About this release

Our quarterly report

The Drugs Team at Public Health Scotland (PHS) has compiled this report of drug-related indicators in order to inform action to prevent drug harms and deaths.

The objectives of this report are to:

  • monitor changes in drug trends, harms and use of services to inform immediate and short-term actions that reduce drug harms
  • detect potential clusters of harms and recommend appropriate responses

Update

This publication was updated on 26 January 2023, with a slight amendment to provide the total figures for October 2022 in the suspected drug deaths indicator.

There was a minor update to this publication on 27 July 2023, in the opioid substitution therapy indicator. The glossary was updated to state that injectable buprenorphine is administered as a subcutaneous injection (previously listed as an intramuscular injection).

Data and reporting period

  • Observed changes in indicators may reflect genuine trends in behaviours but may also be influenced by factors such as the configuration of services, or data quality and completeness issues.
  • This release reports on Scotland-level data. Analysis for some indicators is available by NHS Board in the substance use section of the COVID-19 wider impacts dashboard.
  • These data may be subject to change. Further analysis of these data will be made available in our Official and National Statistics publications on substance use.
  • Different time periods may be reported across the different indicators. In all cases, the most recently available data are used. Most charts are based upon a 2-year time series.
  • Key time periods, during which notable pandemic restrictions were in place, are indicated by reference lines and shaded areas on the charts. For more information on COVID-19 restrictions, view this timeline from the Scottish Parliament Information Centre.

Date of next report

The next release of this publication will be 25 April 2023.

Acknowledgements

This report reflects the collective efforts of different organisations and hundreds of people in frontline and supporting roles who record, organise, analyse and interpret information from a range of sources and services.

We gratefully acknowledge the continued commitment and effort of all those involved.

Summary of indicators

Police Scotland drug trends bulletin

This update provides information on street benzos (benzodiazepines) and nitazenes mis-sold as oxycodone.

Reports of drug harms to RADAR

18 reports were validated by RADAR between 24 September 2022 and 11 January 2023.

Naloxone administration by Scottish Ambulance Service

The number of incidents between September and November 2022 (832) were lower compared to the same time period in 2020 (1,032) and 2021 (1,176).

Drug-related attendances at emergency departments

The number of attendances between September to November 2022 (1,022) were slightly lower than expected for this time period comparing to similar time periods in the previous two years (1,068 attendances in 2021 and 1,114 in 2020).

Drug-related acute hospital admissions

The number of admissions between July and September 2022 (2,024) were considerably lower compared to the same time period in 2020 (3,643) and 2021 (3,033).

Suspected drug deaths

The average weekly number of suspected drug deaths increased in October and November 2022, following a decreasing trend in recent months. There were 76 suspected drug deaths in October 2022 and 109 suspected drug deaths in November 2022. The number of suspected drug deaths in November 2022 (109) was 17% higher than in November 2020 (93) and 22% higher than in November 2021 (89).

Emergency department toxicology: ASSIST

Between August and November 2022, 169 detections of 30 different illicit drugs were identified by the ASSIST pilot. More than one substance was detected in 82% of attendances.

Forensic toxicology testing for controlled substances

During July to September 2022, the most commonly found drugs or drug types in post-mortem testing were opioids (74%) and benzodiazepines (50%). Heroin/morphine was detected in 35% of deaths and there was a continued reduction in detections for etizolam (17%) and methadone (25%).

Drug seizures in Scottish prisons

Synthetic cannabinoids were the most prevalent drug type detected in drug seizures in Scottish prisons during April, detected in 50% of samples. In contrast, benzodiazepines were the most prevalent in May, detected in 27% of samples.

Specialist drug treatment referrals

The number of specialist drug treatment referrals between August to November 2022 (4,620) were lower compared to the same time periods in 2020 (5,092) and 2021 (5,511).

Opioid substitution therapy

The average number of opioid substitution therapy (OST) doses supplied per month decreased slightly in the period from July to September 2022. The number of OST doses supplied during this period was higher than in the same time period in 2018 and 2019, and lower than in the same time period in 2020 and 2021.

Injecting equipment provision

The average weekly numbers of Injecting Equipment Provision (IEP) transactions, and needles and syringes distributed were broadly stable between July and September 2022. The total numbers of IEP transactions, and needles and syringes distributed during this time period were lower compared to the same time periods in 2020 and 2021.

Main points

  • An increase in suspected drug deaths was observed in Scotland between October and November 2022. All other healthcare indicators of harm and service utilisation remained stable and below expected levels. The predominant picture of drugs harms in Scotland continues to be polydrug use involving benzodiazepines, stimulants and opioids. Partners are advised to strengthen harm reduction and support measures with particular consideration for those who may have limited contact with health and social care services.
  • This report also contains an alert on nitazene-type opioids in Scotland, which requires action by people working and volunteering in drug and alcohol services, emergency services, health care settings and high-risk settings.

Alerts

  • RADAR has published a public health alert called nitazene-type opioids in Scotland. This is in response to an increase in the availability of a new group of synthetic opioid drugs called nitazenes.
  • Due to their unexpected presence in the drug supply and high potency, nitazenes pose a substantial risk of overdose, drug-related hospitalisation and drug-related death.
  • This alert details the action required by people working and volunteering in drug and alcohol services, emergency services, health care and medical settings and high-risk settings, such as prisons and hostels.
  • Actions required include sharing harm reduction information, promoting naloxone distribution and increasing awareness of the signs of an overdose.

Trends

  • 18 reports were validated by RADAR between 24 September 2022 and 11 January 2023.
  • Benzodiazepines were the most commonly reported drug type, with seven (39%) reports indicating a benzodiazepine as the ‘primary drug’. Three reports related to bromazolam. Bromazolam is a Class C benzodiazepine that is structurally similar to alprazolam.
  • There were also seven reports where a stimulant was reported to be the ‘primary drug’. Four reports were about the adverse effects of both cocaine powder and crack cocaine.
  • Half of reports mention mixing two or more substances (polydrug use). Mixing drugs can cause unexpected and unpredictable effects and is a major risk factor in drug-related deaths in Scotland.

Harm indicators

  • Scottish Ambulance Service naloxone incidents between September and November 2022 (832) were lower compared to the same time period in 2020 (1,032) and 2021 (1,176).
  • The number of drug-related hospital admissions between July and September 2022 (2,024) were considerably lower compared to the same time period in 2020 (3,643) and 2021 (3,033).
  • Suspected drug deaths increased in October and November 2022, following a decreasing trend in recent months. There were 109 suspected drug deaths in November 2022. This is higher than in the same month in 2020 (93) and 2021 (89).

Toxicology indicators

  • In the ASSIST hospital toxicology pilot, two or more substances were detected in 82% of drug-related emergency department presentations. The most commonly detected drug was cocaine (13%), followed by desmethyldiazepam (11%) and cannabis (9%).
  • Changes were observed in post-mortem toxicology in quarter 3 of 2022, with the percentage of cases testing positive for etizolam (17%) falling below diazepam (24%) for the first time since before 2019. The most commonly detected drug type in post-mortem testing was opioids (74%). Heroin/morphine was detected in 35% of deaths.
  • Prison drug analysis also shows a changing picture of drug use as new synthetic cannabinoids and benzodiazepines continue to appear. Synthetic cannabinoids were the most commonly detected drug type in April 2022, detected in 50% of samples. In contrast, benzodiazepines were the most common in May 2022, detected in 27% of samples.
  • The constant evolution in the types of substances available emphasises the importance of investment in drug checking, forensic post-mortem toxicology and hospital toxicology testing.

Service indicators

  • The number of specialist drug treatment referrals between August and November 2022 were lower compared to the same time periods in 2020 and 2021.
  • The average number of opioid substitution therapy doses supplied per month decreased slightly in the period from July to September 2022. The number of doses supplied during this period was higher than in the same time period in 2018 and 2019, and lower than in the same time period in 2020 and 2021.
  • The average weekly number of injecting equipment provision transactions, and needles and syringes were broadly stable between July and September 2022. The total numbers of transactions and needles and syringes distributed during this time period were lower compared to the same time periods in 2020 and 2021.

Alerts

RADAR publishes ad-hoc alerts related to new drugs, trends and harms.

A public health alert about nitazene-type drugs in Scotland, was published on 24 January 2023.

This alert relates to an increase in the availability of a new group of drugs called nitazenes.

Nitazenes are potent synthetic opioids. Due to their unexpected presence in the drug supply and high potency, nitazenes pose a substantial risk of overdose, drug-related hospitalisation and drug-related death.

Trends

Police Scotland drug trends bulletin

This bulletin contains photos of drugs.

This update provides information on street benzos (benzodiazepines) and nitazenes mis-sold as oxycodone.

This information has been provided by Police Scotland’s STOP Unit to raise awareness of drug appearance and to demonstrate some of the substances present in Scotland’s drugs market.

Street benzos

'Street benzos' is a term used to describe benzodiazepines that are unlicensed or illicitly produced.

Most common benzodiazepines 
  • Etizolam is the most common active ingredient used to produce these tablets, but an increasing number of new benzodiazepine types and forms continue to appear.
  • White ‘10’ with a half score on the reverse is still the most commonly recovered illicitly produced street benzodiazepine tablet.
  • Light blue ‘D/10’ with a half score on the reverse is the second most commonly recovered street benzodiazepine tablet.

Flubromazepam

Flubromazepam is a Class C drug. Some recent recoveries of note are the following tablets:

  • A white tablet with what appears to be a back to front ‘10’, with a half score on the reverse, containing flubromazepam.
Image caption Benzodiazepine tablet: white with back to front 10
Image shows a benzodiazepine tablet that’s white with a back to front 10 on one side.
  • A light blue tablet ‘V10’ with a half score on the reverse, containing flubromazepam.
Image caption Benzodiazepine tablet: light blue V10 with half score on reverse
Image shows a benzodiazepine tablet that’s light blue with V10 on one side and a half score on the reverse.

Bromazolam

There has been a recent increase in the number of bromazolam recoveries across Scotland. Bromazolam is a Class C drug.

According to recent information shared by the Scottish Prison Service, bromazolam has been detected in prisons in tablet and powder form. Reports suggest a link between the use of powder (suspected to be bromazolam) and serious and adverse health effects. The intelligence indicates that it is being obtained in pure powder form and consumed per ‘grain’.

A bulletin issued by Northumbria Police in June 2022 shows bromazolam was detected within ‘benzo bear’ jelly sweets, but no such recoveries have been found in Scotland at this time.

Visit NHS inform for more information on benzodiazepines.

Oxycodone/nitazene tablets

A recovery in Aberdeen found a quantity of tablets bearing oxycodone markings that contained N-pyrrolidino etonitazene, a highly potent opioid.

Oxycodone is available on prescription in the UK and is a Class A controlled drug within the provisions of the Misuse of Drugs Act 1971.

N-pyrrolidino etonitazene is not yet classified under the Misuse of Drugs Act 1971, but recommendations have been made to the Home Office that this drug and other similar synthetic opioids should be classified as Class A in the future.

For more information on this recovery, see the Police Scotland interim drug bulletin (10 November 2022).

For more information on nitazenes, see the nitazene-type drugs in Scotland RADAR alert.

Reports of drug harms to RADAR

18 reports were validated by RADAR between 24 September 2022 and 11 January 2023.

A summary of validated reports is shown below for informational purposes.

These were received through our online reporting form and mailbox.

These reports have been collected as part of intelligence gathering.

PHS recommends the widespread use of the following harm reduction messages and interventions across Scotland.

Be cautious

Drugs in circulation can vary widely
  • The drug purchased may not always be the drug that it’s expected to be.
  • It may contain adulterants, be mis-sold or contain a different amount than anticipated.
Test before use
  • Drug contents cannot be confirmed by the way it looks, smells or tastes.
  • People in Scotland can get their drugs tested by using the free, anonymous postal service provided by WEDINOS.
Mixing drugs is dangerous and should be avoided
  • Mixing drugs increases the risk of drug harms and death – this includes mixing alcohol with other drugs.
  • Those taking medicines should research any potential interactions between their medicines and the drugs they are taking.
  • The risk of overdose is also increased if someone takes drugs alone, takes drugs after a break, takes higher purity drugs than expected or injects drugs.
Get help in an emergency
  • If someone needs medical help, call 999, ask for an ambulance and stay with the person until help arrives.
  • If the person is non-responsive and displaying the signs of an overdose (unconsciousness, shallow breathing, snoring, blue lips, pale skin, pin-point pupils), administer naloxone.

Harm indicators

Naloxone administration by Scottish Ambulance Service

The average weekly number of naloxone administration incidents was broadly stable between September and November 2022 (69 incidents per week). The total number of incidents during this time period (832) was lower compared to the same time periods in 2020 (1,032) and 2021 (1,176).

Background

Naloxone is a medicine used to prevent fatal opioid overdoses. These data relate to the number of incidents in which naloxone was administered by Scottish Ambulance Service (SAS) clinicians.

While these data count multiple overdose patients at the same incident separately, multiple naloxone administrations to the same patient at the same incident are not counted separately.

The chart below shows the weekly number of SAS naloxone administration incidents from 31 August 2020 to 27 November 2022.

Image caption Naloxone administration by Scottish Ambulance Service

Summary

Historic trend
  • Until winter 2021, the average weekly number of SAS naloxone administration incidents was similar to previous years, which have generally been characterised by lower numbers of incidents during winter months and higher numbers during summer months.
  • In spring 2022, the trend diverged from previous years and, in spite of an increase in April, the number of naloxone incidents has remained relatively stable since January 2022. At the end of May 2022, the number of naloxone incidents was approximately 25% lower compared to the same time period in 2021.
Update

For the most recent time period (5 September to 27 November 2022):

  • 832 SAS naloxone incidents were recorded, at an average of 69 per week. Weekly numbers of incidents were generally stable throughout this period.
  • The total number of incidents was 8% lower than in the previous 12-week time period (13 June to 4 September 2022) when 904 incidents were recorded, at an average of 75 per week.
  • The total number of incidents was 19% lower than expected compared to the same time period in 2020 (1,032 attendances, average of 86 per week) and 29% lower than in 2021 (1,176 attendances, average of 98 per week).

Additional information

PHS was provided with these data by SAS.

For more information, or to analyse this data by NHS board, visit the COVID-19 wider impacts dashboard.

Why we use a 3-week moving average  

As these data are highly variable over time, a 3-week moving average has been included in the graph to aid interpretation of trends over time.

 

Scotland’s Take-Home Naloxone Programme

The Take-Home Naloxone Programme was launched by the Scottish Government in 2011 to prevent fatal opioid overdoses.

Naloxone is a medicine that can temporarily reverse the effects of an opioid overdose. It can be given to anyone who is non-responsive and displaying the signs of an overdose (unconsciousness, shallow breathing, snoring, blue lips, pale skin, pin-point pupils).

Anyone in Scotland can carry naloxone. It can be accessed through most local drug services or pharmacies and it can also be delivered to your home through the charity Scottish Families Affected by Alcohol and Drugs.

Naloxone is very easy to administer.

You can learn more about administering naloxone in a free e-learning module created by the Scottish Drugs Forum.

Information on Take-Home Naloxone distribution can be found in the substance use section of the COVID-19 wider impacts dashboard and in the National Naloxone Programme Scotland Quarterly Monitoring Bulletin, both published by PHS.

Drug-related attendances at emergency departments

Average attendances were stable between September and November 2022 (1,022 attendances). Number of attendances were slightly lower than expected for this time period comparing to similar time periods in the previous two years (1,068 attendances in 2021 and 1,114 in 2020).

Background

A drug-related emergency department (ED) attendance is an attendance for a drug intoxication or overdose, either alone, or combined with alcohol intoxication. 

The chart below shows the weekly number of drug-related ED attendances between 2 November 2020 and 27 November 2022. 

Image caption Drug-related attendances at emergency departments

Summary

Historic trend
  • An overall decreasing trend was observed in drug-related attendances at EDs between August 2021 and April 2022, with the lowest weekly levels in the time series observed in the week beginning 4 April 2022 (54).
  • Drug-related ED attendances then increased sharply and peaked in May 2022, with the highest weekly levels in the time series observed in the week beginning 16 May 2022 (123).
  • Attendances then decreased remaining fairly stable, averaging 83 attendances per week throughout June, July and August 2022.
Update

For the most recent time period (5 September to 27 November 2022):

  • 1,022 ED attendances were recorded, an average of 85 per week. This was 3% higher than the previous twelve-week time period - 13 June to 29 August 2022 (990 attendances, average of 83 per week).
  • Attendances were slightly lower when comparing to the similar time period in 2021 (1,068 attendances, average of 89 per week) and 8% lower than those in 2020 (1,114 attendances, average of 93 per week).

Additional information

These data are taken from our Accident and Emergency Data Mart.

Diagnosis and reason for attendance can be recorded in a variety of ways, including in free text fields. Therefore, the numbers presented in this report only give a high-level indication of attendances over time.

Why we use a 3-week moving average

As these data are highly variable over time, a 3-week moving average has been included in the graph to aid interpretation of trends over time.

Drug-related acute hospital admissions

The average weekly number of drug-related hospital admissions were stable between July and September 2022. The total number of admissions in this time period (2,024) was significantly lower than expected, compared to the same time period in 2020 (3,643) and 2021 (3,033) (decreases of 44% and 33% respectively).

Background

The data used in these statistics relate to all inpatient and day case admissions to general acute hospitals (excluding maternity, neonatal, geriatric long stay and admissions to psychiatric hospitals), where drug use was recorded as a diagnosis at some point during the patient’s hospital stay. Data are presented by date of admission.

The chart below shows the weekly number of drug-related admissions to Scotland’s general acute hospitals from 29 June 2020 to 25 September 2022.

Image caption Drug-related hospital admissions

Summary

Historic trend
  • There was a long-term decreasing trend in the average weekly number of drug-related hospital admissions from June 2021 to April 2022. Admissions briefly increased in April and May 2022, before decreasing again in June 2022.
  • The long-term decreasing trend in drug-related hospital admissions observed since June 2021 differs markedly from previous years, which have generally been characterised by lower numbers of admissions during winter months and higher numbers during summer months.
Update

For the most recent time period (27 June to 25 September 2022):

  • 2,024 drug-related hospital admissions were recorded, at an average of 155 per week. Weekly numbers of admissions were generally stable throughout this period, ranging from 130 to 180.
  • The total number of admissions was lower than expected compared to previous years:
    • 44% lower than the same period in 2020 (3,643, at an average of 280 per week); and,
    • 33% lower than the same period in 2021 (3,033, at an average of 233 per week).
  • The most common substance type recorded in drug-related general acute hospital admissions between July and September 2022 was opioids (47% of admissions).

Additional information

These data have been extracted from our SMR01 dataset.

The data presented on drug type is based on ICD-10 diagnostic codes and is not confirmed by toxicology analysis.

For more information on diagnostic coding, please refer to the drug-related hospital statistics publication methods page.

To analyse the latest published information by NHS Board or by Alcohol and Drug Partnership (ADP), go to our information on drug-related hospital statistics admissions.

Why we use a 3-week moving average

As these data are highly variable over time the 3-week moving average has been included in the graph to account for this variability and provide an average line.

Glossary

 

Opioids

Opioid drugs act on opioid receptors to produce sedative and painkilling effects. They are respiratory depressants (reduce heart rate and breathing). Opioids include synthetic (lab-made) drugs such as methadone and buprenorphine, as well as opiates (drugs made from opium) such as heroin and morphine.

Suspected drug deaths

The average weekly number of suspected drug deaths increased in October and November 2022, following a decreasing trend in recent months. There were 76 suspected drug deaths in October 2022 and 109 suspected drug deaths in November 2022. The number of suspected drug deaths in November 2022 (109) was 17% higher than in November 2020 (93) and 22% higher than in November 2021 (89).

Background

Suspected drug death figures are based on reports from police officers attending scenes of death. The details of these events are recorded by Police Scotland and shared with Public Health Scotland.

Following further investigation, these suspected drug deaths are either confirmed as a ‘drug-related death’ or determined ‘not to be a drug death’. This can take several months so suspected figures are used to provide a timely indication of trends and inform prevention activity.

The chart below shows the weekly number of suspected drug deaths in Scotland from 28 June 2020 to 27 November 2022.

Image caption Suspected drug deaths

Summary

Historic trend

  • Following a large increase in suspected drug deaths in Scotland during December 2020, there was a decreasing trend in the average weekly number of deaths until May 2021. The number of suspected drug deaths increased during summer 2021, peaking at 34 in the week beginning 7 June 2021.
  • Between July 2021 and June 2022, the average number of suspected drug deaths remained relatively stable, generally ranging between 15 and 25 deaths per week.

Update

For the most recent time period (4 July to 27 November 2022):

  • An average of 20 suspected drug deaths were recorded per week (ranging between 12 and 31). This was slightly lower than for the same weeks in 2020 and 2021 (an average of 22 deaths per week in both years).
  • There was an increase in the average number of suspected drug deaths per week during October and November 2022. In the week beginning 31 October 2022, there were 31 suspected drug deaths. This was a 72% increase compared to the previous week (18) and the highest weekly total recorded since week beginning 30 May 2022 (32).

Additional information

Drug-related death

A drug-related death (also referred to as drug-misuse death) is a death where the underlying cause was confirmed to be drug poisoning and where any of the substances that were implicated or potentially contributed to the death are controlled in the UK. National Statistics on drug-related deaths are published by NRS. In 2021, there were 1,330 drug-related deaths in Scotland. This was a small decrease compared to 2020 (1,339), which saw the highest annual total on record.

Suspected drug death

A suspected drug death is a death where controlled drugs are suspected of being involved. This operational measure used by Police Scotland is based on the reports, observations and initial enquiries of officers attending the scene of death.

Toxicology indicators

Emergency department toxicology: ASSIST

Between August and November 2022, 169 detections of 30 different illicit drugs were identified by the ASSIST pilot. More than one substance was detected in 82% of attendances. The most commonly detected drug category was depressants (58%), followed by stimulants (27%). The most commonly detected drug was cocaine (13%), followed by desmethyldiazepam (11%).

Background

The ASSIST (A Surveillance Study in Illicit Substance Toxicity) pilot conducted by the emergency department (ED) at the Queen Elizabeth University Hospital (QEUH) aims to assess the feasibility of prospective surveillance of ED attendances due to acute illicit drug toxicity.

The study collects anonymised data through analysis of standard of care clinical data for severely ill patients attending the ED due to illicit drug toxicity.

The use of the term ‘illicit drug’ encompasses any substance that is controlled. It excludes:

  • legal substances such as alcohol, nicotine, caffeine and paracetamol
  • medications recently prescribed to the individual
  • drugs administered to the individual as part of treatment (by ambulance or hospital)

The pilot enables full toxicological analysis through the biorepository. This allows drug profiling and the identification of emerging drugs or changing trends, to inform appropriate harm reduction measures and public health responses.

This pilot will run in the QEUH ED in Glasgow from August 2022 to August 2023, followed by a three-month follow up period.

Toxicology analysis of surplus serum samples

Surplus serum samples are left over blood samples, that were taken as part of usual care. The chart below shows the most common drug categories detected in toxicology analysis of surplus serum samples between 17 August 2022 and 16 November 2022. The results are shown as the total number of detections, broken down by top five drug categories and then broken down further by drug name.

Image caption Toxicology analysis of surplus serum samples: drug category

Summary

For the most recent time period (17 August 2022 to 16 November 2022), 273 discreet ED attendances related to illicit drug use were identified.

Drug type and category

Complete toxicology and clinical data are available for 38 attendances, with results described below. Results from the remaining attendances will be available in the next report.

Glossary

Depressants

Depressant drugs depress the central nervous system, which also decreases heart rate and breathing. Depressant drugs include substances such as benzodiazepines and gabapentinoids.

Benzodiazepines are a group of drugs with depressant and anxiolytic (anti-anxiety) effects. They are also known as tranquilisers. Benzodiazepines (and metabolites) detected in this project include desmethyldiazepam, etizolam, temazepam, oxazepam, diazepam, bromazolam, gidazepam, flubromazepam, flualprazolam, lorazepam, nitrazepam and alprazolam. Please note that desmethyldiazepam, temazepam and oxazepam are all benzodiazepine drugs in their own right but can also be found as a metabolite of diazepam.

Gabapentinoids (pregabalin and gabapentin) are a group of drugs with depressant and painkilling effects.

Stimulants

Stimulant drugs stimulate the central nervous system, which also increases heart rate and breathing. Stimulants drugs include substances such as cocaine and amphetamines.

Cocaine is a short-lasting stimulant drug that increases heart rate and breathing. This group includes powder cocaine and crack cocaine.

Other stimulants are stimulant drugs apart from cocaine. Stimulants detected in this project include amphetamine, methamphetamine, MDMA, mephedrone and MDA.

Opioids

Opioid drugs act on opioid receptors to produce sedative and painkilling effects. They are respiratory depressants (reduce heart rate and breathing). Opioids detected in this project include codeine, methadone, dihydrocodeine, tramadol, dihydromorphine, buprenorphine and morphine.

Cannabinoids

Cannabinoids are compounds that interact with the endocannabinoid system. They are found in the cannabis plant (such as THC) or can be produced synthetically in a laboratory (synthetic cannabinoids). No synthetic cannabinoids were detected in this project. All cannabinoid detections are for cannabis.

Unique ED attendances

In this quarter there was a total of 273 unique attendances to the emergency department related to illicit drug use. Each separate attendance is counted as one. If the same person presented more than once, each attendance would be a separate data point.

Illicit drug

The use of the term 'illicit drug' encompasses any substance that is controlled. It excludes:

  • Legal substances such as alcohol, nicotine, caffeine and paracetamol
  • Medications recently prescribed to the individual
  • Drugs administered to the individual as part of treatment (by ambulance or hospital)
Metabolite

A drug metabolite is a compound produced when a drug breaks down in the body.
In this study, if either a drug or metabolite are detected, this will only be included as one substance – the drug. For example, if both diazepam and its metabolite desmethyldiazepam are detected, only diazepam is recorded.
If only a metabolite is detected this will be documented as the substance.
Due to this we are unable to ascertain the source of some substances, for example, oxazepam is a benzodiazepine, but it is also a metabolite of a range of other benzodiazepines, so we cannot determine whether oxazepam or another benzodiazepine was consumed.

Forensic toxicology testing for controlled substances

The total number of deaths testing positive for controlled substances via Forensic Medicine and Science (FMS) toxicology testing was 16% lower in Q3 of 2022 (1 July 2022 to 30 September 2022) than in Q2 (1 April 2022 to 30 June 2022).
In Q3 of 2022, the most commonly found drugs or drug types were opioids (74%) and benzodiazepines (50%). Heroin/morphine was detected in 35% of deaths and there was a continued reduction in detections for etizolam (17%) and methadone (25%).

Background

This analysis is based on toxicology testing data completed at post-mortem.

This testing was performed by the Forensic Toxicology Service based within FMS at the University of Glasgow, on behalf of the Crown Office and Procurator Fiscal Service.

The range of substances routinely analysed by this service is extensive and includes the detection of alcohol, prescribed medicines and controlled drugs.

The first chart below provides an indication of controlled drugs found present at post-mortem in deaths occurring between 1 January 2020 and 30 September 2022.

The second chart provides an indication of specific opioids and benzodiazepines found present at post-mortem in deaths occurring between 1 January 2020 and 30 September 2022.

Image caption Forensic toxicology cases testing positive for specific opioids and benzodiazepines

Summary

Historic trend
  • In total, 2,172 deaths occurred in 2021 where controlled drugs were found present via FMS toxicology testing, which was 2% higher than in 2020 (2,136).
  • The most commonly found drug types were opioids and benzodiazepines. The percentage of deaths with these drugs present increased during the time period when the initial COVID-19 restrictions were in place (Q2 of 2020) and remained high throughout 2020 to Q2 of 2021, but has been decreasing since Q3 of 2021.
  • The specific drugs most commonly present throughout the time series (from Q1 of 2020 to Q2 of 2022) were etizolam, methadone and heroin/morphine, with etizolam and methadone both increasing sharply in Q2 of 2020.
  • Although there was a gradual reduction in deaths where methadone was found present, etizolam presence remained high throughout 2020 and early 2021 before sharply decreasing in Q3 of 2021.
  • The percentage of deaths involving diazepam, other opioids, gabapentin/ pregabalin or cocaine have remained relatively stable over time.
Update
  • The total number of deaths testing positive for controlled substances via FMS toxicology testing was 16% lower in Q3 of 2022 (1 July 2022 to 30 September 2022) than in Q2 (1 April 2022 to 30 June 2022) and 9% lower than in Q3 of 2021.
  • In Q3 of 2022, the following drugs or drug types were most commonly detected:
    • opioids: 329 (74%)
    • benzodiazepines: 221 (50%)
    • gabapentin/pregabalin: 152 (34%)
    • cocaine: 130 (29%)
  • Following a continued reduction in cases testing positive for etizolam (from 35% in Q1 to 17% in Q3) and methadone (from 34% in Q1 to 25% in Q3), the most commonly found substance was heroin/morphine (35% in Q3 of 2022).
  • In Q3 of 2022, the percentage of cases testing positive for etizolam fell below diazepam (24% in Q3 of 2022), which remained relatively stable.
  • There were no deaths positive for clonazolam via FMS testing in Q3 of 2022, in comparison to a peak of 12% of deaths in Q3 of 2021.
  • Other toxicology sources suggest the ‘street’ benzodiazepine market continues to diversify, with substances such as bromazolam increasingly in use. The decrease in benzodiazepine detections described above may be due to these emerging compounds not being included in testing during this time period. These data will develop further as bromazolam (and other new or emerging drugs) are added to toxicology screening in the coming months.

Additional information

PHS was provided with these data by FMS, University of Glasgow.

Detailed interpretation of the levels of drugs found present, drug interactions, co-morbidities or other factors relating to death are outside the scope of this analysis. This analysis does not imply that specific drugs were implicated in deaths nor that deaths were classified as ‘drug-related’ and does not include consideration of wider causes of death.

The data above are for deaths occurring in the west, east and parts of the north of Scotland. Apart from a very small number of cases analysed at the University of Glasgow, post-mortem toxicology testing for deaths occurring in Aberdeen and the far north of Scotland is conducted by a similar service at the Aberdeen Royal Infirmary (ARI). Results from the ARI are not included in the analysis above.

Drug seizures in Scottish prisons

Synthetic cannabinoids were the most prevalent drug type in the Scottish Prisons Non-Judicial Drug Monitoring Project during April, detected in 50% of samples. In contrast, benzodiazepines were the most prevalent in May, detected in 27% of samples.

Background

The Leverhulme Research Centre for Forensic Science (LRCFS) is currently undertaking research with the Scottish Prison Service (SPS). The Scottish Prisons Non-Judicial Drug Monitoring Project tests drug seizures made across the Scottish prison estate in order to understand the changing characteristics of synthetic drugs, including synthetic cannabinoids, often referred to as ‘spice’.

The chart below shows the five drug types most commonly detected in drug seizures in Scottish prisons between 1 September 2020 and 31 May 2022, based on the percentage of all samples tested.

The second chart shows the four sample types most commonly seized in Scottish prisons between 1 September 2020 and 31 May 2022, based on the percentage of all samples tested.

Image caption Drug seizures in Scottish prisons: sample type

Summary

Historic trend
  • Synthetic opioids were the most common substances seized throughout the time series, followed by benzodiazepines. However, both were highly variable over time:
    • The percentage of seizures testing positive for synthetic cannabinoids decreased markedly between July 2021 (57%) and January 2022 (15%). Overall, an average of 47% of seizures in 2021 tested positive for synthetic cannabinoids compared with 19% between January and March 2022.
    • The percentage of seizures testing positive for benzodiazepines fluctuated throughout 2021 with an average of 45% per month for the year (ranging from 21% to 48%). The percentage then decreased and remained stable from January to March 2022 (average of 22%).
  • Opioid detections increased at the start of 2022, averaging 17% per month from January to March 2022 compared to 4% in 2021.
  • Paper samples were the most common sample types seized in 2021, accounting for an average of 53% of samples per month. This fell to an average of 26% per month from January to March 2022. Increasing trends in the percentage of powder (average of 17% per month) and tablet (35% per month) samples were observed from January to March 2022.
Update

Please note, that data for the full time period (April to June 2022) were not available. This update provides analysis of samples seized in April and May 2022 (63 samples).

For the most recent time period (1 April 2022 to 31 May 2022):

  • The three most commonly detected drugs were ADB-BUTINACA (synthetic cannabinoid), ADB-HEXINACA (synthetic cannabinoid) and etizolam (benzodiazepine).
  • Synthetic cannabinoids were the most common drug type, detected in an average of 30% of seizures. This was lower than the same time period in 2021 (50%).
  • Benzodiazepines were the second most common drug type, detected in an average of 29% of seizures. This was higher than the same time period in 2021 (24%).
  • A continuing increasing trend in the percentage of powder and paper samples was observed in April (39% paper, 38% powder). Paper samples decreased in May (11% compared to a monthly average of 53% in 2022). An increase in tablet samples was also observed (38%).

Further findings

A small number of samples (31) were tested between June and September 2022, with these broadly following previously observed trends. 58% of samples tested positive for synthetic cannabinoids and 32% for benzodiazepines.

Additional information

PHS was provided with these data by SPS and LRCFS.

The Scottish Prisons Non-Judicial Drug Monitoring Project is a collaboration between the SPS and the LRCFS at the University of Dundee.

An initial pilot project ran between September 2018 and January 2021. The project has been directly funded by SPS since February 2021.

Glossary

Benzodiazepines

Benzodiazepines are a group of drugs with depressant and anxiolytic (anti-anxiety) effects. They are also known as tranquilisers. Benzodiazepines detected in this project include etizolam, flubromazepam, bromazolam, diazepam and flualprazolam.

Gabapentinoids

Gabapentinoids are a group of drugs with depressant and painkilling effects. On average, in this project 16% of gabapentinoid detections are for gabapentin and 84% are for pregabalin.

Opioids

Opioid drugs act on opioid receptors to produce sedative and painkilling effects. They are respiratory depressants (reduce heart rate and breathing). Opioids include synthetic (lab-made) drugs such as methadone and opiates (drugs made from opium) such as heroin. Opioids detected in this project include buprenorphine, heroin, tramadol, codeine, dihydrocodeine, metonitazene, oxycodone and methadone.

Synthetic cannabinoids

'Synthetic cannabinoids' is a term used to describe over 200 lab-made drugs that interact with the endocannabinoid system.

The prevalence of synthetic cannabinoids in seizures is higher in prisons than in the general population.

People working and living in prisons should be aware of the harmful effects and risks of synthetic cannabinoid use.

Visit NHS inform for more information on synthetic cannabinoids.

Service indicators

Specialist drug treatment referrals

The average weekly number of referrals to specialist drug treatment services was stable from August to November 2022. The number of referrals during this time period (4,620) was lower compared to the same time periods in 2020 (5,092) and 2021 (5,511).

Background

Specialist drug treatment referrals occur when a person comes into contact with services designed to support their recovery from problem drug use.

Figures shown are for referrals relating to either drug use or co-dependency (people seeking help for both drug and alcohol use). Figures include new referrals for treatment and referrals between services.

The chart below shows the weekly number of referrals to specialist drug treatment services between 7 August 2020 and 13 November 2022.

Image caption Specialist drug treatment referrals

Summary

Historic trend
  • The average weekly number of referrals increased from September 2020 to May 2021, reaching a peak of 554 in week beginning 17 May 2021.
  • Referrals decreased throughout June and July 2021, and then remained stable to January 2022 (between 400-480 referrals per week, apart from the seasonal decrease in December and January).
  • From January 2022 onwards, there has been a gradual decrease in the average weekly number of referrals.
Update

For the most recent time period (22 August to 13 November 2022):

  • 4,620 specialist drug treatment referrals were recorded, at an average of 385 per week.
  • This was almost the same as the previous twelve-week time period (30 May to 21 August 2022) when 4,622 referrals were recorded, at an average of 385 per week.
  • Referrals were 9% lower compared to the same time period in 2020 (5,092, at an average of 424 per week) and 16% less than those in 2021 (5,511, at an average of 459 per week).

Opioid substitution therapy

The average number of OST doses supplied per month decreased slightly in the period from July to September 2022. The number of OST doses supplied during this period was higher than in the same time period in 2018 and 2019, and lower than in the same time period in 2020 and 2021.

Background

The data used in these statistics relate to the number of average daily quantity (ADQ) doses for opioid substitution therapy (OST) drugs dispensed in the community in Scotland. OST drugs include methadone, oral buprenorphine and injectable buprenorphine.

The first chart below shows the average total monthly number of ADQ doses supplied for OST medications in the community between January 2018 and September 2022.

Image caption Average total number of OST doses per month

The chart below shows monthly trends in the number of ADQ doses supplied for specific OST medications in the community between January 2018 and September 2022.

Image caption Number of doses per month for OST medications

Summary

Historic trend
  • From early 2018 to early 2020, the average total monthly number of OST doses supplied was broadly stable. In February 2020, the number of OST doses increased, peaking in June 2020. There was a decreasing trend in the average monthly total number of OST doses supplied between July 2020 and June 2022.
  • The average monthly number of methadone doses supplied was stable from early 2018 to early 2020, increased between February 2020 and June 2020 and has gradually decreased since then.
  • The average monthly number of oral buprenorphine doses supplied increased gradually from early 2018 to June 2020 and has remained broadly stable since.
  • Injectable buprenorphine was first licensed for use in Scotland in early 2020. The average total number of doses supplied has increased steadily since then, to approximately 63,000 in June 2022.
Update

For the most recent time period (July to September 2022):

  • The average total monthly number of OST doses supplied was approximately 747,800.
    • This was roughly the same as in the previous quarter (April to June 2022) when approximately 749,700 doses were supplied.
    • The number of OST doses supplied was higher (both 3%) than in July to September in 2018 and 2019 and lower (5% and 3% respectively) than in the same time period in 2020 and 2021.
  • The average monthly number of methadone doses supplied was approximately 563,900. Equivalent figures for oral buprenorphine and injectable buprenorphine were 118,300 and 65,700 respectively.
    • The number of methadone doses was lower than in the previous quarter (April to June 2022) when approximately 569,000 doses were supplied.
    • The number of methadone doses supplied was between 8% and 16% lower than in July to September in previous years (2018 to 2021).
    • The number of oral buprenorphine doses supplied was roughly the same as in the previous quarter, higher than the same time period in 2018 and 2019 (21% and 12% higher respectively) and lower than the same time period in 2020 and 2021 (7% and 6% lower respectively).
    • The number of injectable buprenorphine doses was 5% higher than in the previous quarter and 44% higher than in the same time period in 2021.

Additional information

These data have been extracted from Prescribing Information System (PIS) and the Hospital Medicines Utilisation Data Manual (HMUD).

The data shown on methadone and oral buprenorphine, and the majority of injectable buprenorphine data, relate to prescriptions dispensed to an individual from a community pharmacy in Scotland where a request for reimbursement of costs was processed. These community prescribing data are extracted from PIS. The time period reflects the month for which reimbursement was claimed. This is regarded as the most comprehensive and reliable way of reporting community prescribing data. There can be a lag of approximately three months from a prescription being written to reimbursed data becoming available.

As a consequence of the direct administration of injectable buprenorphine within clinics, some NHS Boards do not request the reimbursement of costs for all of the OST treatments they provide. Data for approximately 30% of injectable buprenorphine doses supplied in Scotland are held in HMUD and have been combined with the community prescribing data to provide a comprehensive account of OST supply over time.

The time period shown for HMUD data reflects the month in which medication was purchased. For injectable buprenorphine, the length of time between the purchase and administration of medication is thought to be generally short. Therefore, the differences in the basis of the time periods shown in PIS and HMUD data are not thought to negatively impact the reliability of this analysis.

Why we use a 3-month moving average

As these data are highly variable over time, a 3-month moving average has been included in the charts to aid interpretation of trends over time.

Even if all other factors are constant (for example, the number of treated patients), the total number of ADQ doses supplied will vary according to the number of days in each month. Averaging over three months minimises the impact of that variability.

What is average daily quantity (ADQ)?

When comparing use between medicines and over time, it is common to use World Health Organization (WHO) Defined Daily Doses (DDDs). The DDD is defined as the usual average daily maintenance dose used in adults for the main therapeutic use of the medicine. The WHO DDD is a global average and may not be representative of the doses used in clinical practice at a more local level. This is particularly the case for methadone, where the WHO DDD of 25 milligrams (mg) daily is between one-half and one-third of the normal maintenance dose used in Scotland.

We have therefore replaced DDDs with ADQs, which are more representative of the daily maintenance doses used within Scotland. These values have been developed through a combination of prescription analyses and by consultation with the Specialist Pharmacists in Substance Misuse group. The ADQs agreed are:

  • methadone (oral): 65 mg
  • buprenorphine (oral): 13 mg
  • buprenorphine (parenteral/injectable): 3.4 mg

Glossary

Methadone

Methadone is an opioid drug commonly prescribed as an opioid substitution therapy. Methadone is a full opioid agonist – it is most commonly seen as a green liquid, which is swallowed. These data refers to methadone prepared as a 1 mg/ml solution.

Buprenorphine

Buprenorphine is an opioid drug commonly prescribed as an opioid substitution therapy. Buprenorphine is a partial opioid agonist – it is available in oral and injectable forms:

  • Oral buprenorphine is buprenorphine in tablet form that is administered orally (by mouth, usually sub-lingual – under the tongue). It is also known by brand names such as Subutex. These data include 2 mg, 8 mg and 16 mg tablets.
  • Injectable buprenorphine is buprenorphine in liquid form that is administered as a subcutaneous injection. It is also known by brand names such as Buvidal. These data include various weekly and monthly prolonged release formulations
Defined daily dose (DDD)

As defined by the World Health Organization, the DDD is ‘the assumed average maintenance dose per day for drug use for its main indication in adults’.

Average daily quantity (ADQ)

ADQ is similar to the DDD but adjusted to reflect how medication is used in Scotland.

Injecting equipment provision

The average weekly numbers of Injecting Equipment Provision (IEP) transactions and needles and syringes distributed were broadly stable between July and September 2022. The total numbers of IEP transactions and needles and syringes distributed during this time period were lower compared to the same time periods in 2020 and 2021.

Background

IEP is a form of harm reduction that helps to reduce the transmission of blood borne viruses among people who inject drugs. These data relate to the number of needle/syringe transactions at IEP sites and the total number of needles and syringes distributed.

The first chart below shows the weekly number of IEP transactions from 29 June 2020 to 2 October 2022.

Summary

Historic trend

  • There was an overall decrease in the average weekly number of IEP transactions from June 2020 to February 2022. This trend included seasonal fluctuations during December and January each year. Since February 2022, average numbers of IEP transactions have been relatively stable (approximately 3,000 per week).
  • A fluctuating decreasing trend in the average weekly number of needles and syringes distributed was observed from June 2020 to July 2021. Since July 2021, the average number distributed has remained relatively stable (approximately 37,500 per week).

Update

For IEP transactions in the most recent time period (4 July 2022 to 2 October 2022):

  • 38,644 transactions were recorded, at an average of 2,973 per week.
  • This was comparable to the previous time period (4 April to 3 July 2022) when a total of 38,102 were recorded, at an average of 2,931 per week.
  • The total number of transactions was 17% lower compared to the same time period in 2020 (46,365, at an average of 3,567 per week), and 15% lower compared to those in 2021 (45,221, at an average of 3,230 per week).

For needles and syringes distributed in the most recent time period (4 July 2022 to 2 October 2022):

  • 492,782 needles and syringes were distributed, at an average of 37,906 per week.
  • This was comparable to the previous time period (4 April to 3 July 2022) when a total of 483,377 needles and syringes were distributed, at an average of 37,183 per week.
  • The total number of needles and syringes distributed in the most recent time period was 14% lower compared to the same time period in 2020 (571,559, at an average of 43,966 per week), and 11% lower compared to those in 2021 (554,021, at an average of 39,573 per week).

Additional information

These data are taken from the Needle Exchange Online 360 database (neo360).

The 11 mainland NHS Boards use neo360 routinely, but due to missing data for part of the time period presented, NHS Highland is excluded from the transaction data, and both NHS Fife and NHS Highland are excluded from the needle and syringe figures.

For more information, or to analyse these data by NHS board, visit the COVID-19 wider impacts dashboard.

For details of injecting equipment providers in your area, visit the Scottish Needle Exchange Directory.

Why we use a 3-week moving average

As these data are highly variable over time, a 3-week moving average has been included in the graph to aid interpretation of trends over time.

Glossary

Transaction

A transaction is an episode in which a client received equipment relating to an injecting episode (i.e. a barrel and/or fixed needle and syringe). People who inject drugs may attend IEP outlets at any time, whether or not they are undertaking specialist treatment for problematic drug use.

N/A

Concepts and definitions

Naloxone is a medicine used to prevent fatal opioid overdoses. Opioid overdoses are commonly associated with drug-related deaths. These data on the numbers of incidents in which naloxone was administered by SAS clinicians provide an indication of numbers of suspected opioid overdoses.

A small percentage of these administrations will have been due to circumstances other than an illicit opioid overdose (for example, some may relate to prescribed opioid overdoses or to adverse reactions associated with medications administered in the course of emergency treatment).

Also, in a small number of cases, naloxone may be administered to someone who is unconscious for unconfirmed reasons, which may be confirmed at a later point not to have been an opioid overdose. While these data count multiple overdose patients at the same incident separately, multiple naloxone administrations to the same patient at the same incident are not counted separately.

Under some circumstances, naloxone administration will not successfully reverse an opioid overdose (for example, if administered too late) and these statistics should not be interpreted as equating to numbers of lives saved.

Further details can be found in the substance use section of the COVID wider impacts dashboard.

Concepts and definitions

Drug-related death

A drug-related death (also referred to as drug misuse death) is a death where the underlying cause was confirmed to be drug poisoning and where any of the substances which were implicated, or potentially contributed to death, are controlled in the UK. National Statistics on drug-related deaths are published by NRS. In 2021 there were 1,330 drug-related deaths in Scotland. This was a small decrease compared to 2020 (1,339), which saw the highest annual total on record.

Suspected drug death

A suspected drug death is a death where controlled drugs are suspected of being involved. This operational measure used by Police Scotland is based on the reports, observations and initial enquiries of officers attending the scene of death.

Emergency department toxicology: ASSIST

Publication title

Rapid Action Drug Alerts and Response (RADAR) quarterly report – January 2023

Description

This indicator provides information on number of attendances, length of stay and toxicology of presentations due to acute illicit drug toxicity at the Queen Elizabeth University Hospital (QEUH) emergency department (ED), Glasgow, Scotland. This study assesses the feasibility of prospective surveillance of ED presentations due to acute illicit drug toxicity.

Continuity of data

ASSIST: A Surveillance Study in Illicit Substance Toxicity is a pilot by the ED at the QEUH. It will run from August 2022 to August 2023, followed by a three-month follow up period.

QEUH will provide Public Health Scotland with toxicology screening data on a quarterly and ad-hoc basis for the purposes of public health surveillance.

Because the sample size is small, some of the variables are combined in a different way to the data shared in quarterly report 1 (October 2022), to ensure that they are completely non-identifiable. Later outputs may have narrower categories as the numbers become greater.

Revisions statement

N/A

Concepts and definitions

Unique ED attendances

In this quarter there was a total of 273 unique attendances to the ED related to illicit drug use. Each separate attendance is counted as one. If the same person presented more than once, each attendance would be a separate data point.

Illicit drug

The use of the term ‘illicit drug’ encompasses any substance that is controlled. It excludes:

  • legal substances such as alcohol, nicotine, caffeine and paracetamol
  • medications recently prescribed to the individual
  • drugs administered to the individual as part of treatment (by ambulance or hospital)

Metabolite

A drug metabolite is a compound produced when a drug breaks down in the body.

In this study, if either a drug or metabolite are detected, this will only be included as one substance – the drug. For example, if both diazepam and its metabolite desmethyldiazepam are detected, only diazepam is recorded.

If only a metabolite is detected this will be documented as the substance.

Due to this we are unable to ascertain the source of some substances, for example, oxazepam is a benzodiazepine, but it is also a metabolite of a range of other benzodiazepines, so we cannot determine whether oxazepam or another benzodiazepine was consumed.

Benzodiazepines

Benzodiazepines are a group of drugs with depressant and anxiolytic (anti-anxiety) effects. They are also known as tranquilisers.

Cocaine

Cocaine is a short-lasting stimulant drug that increases heart rate and breathing.

Gabapentinoids

Gabapentinoids are a group of drugs with depressant and painkilling effects.

Opioids

Opioid drugs act on opioid receptors to produce sedative and painkilling effects. They are respiratory depressants (reduce heart rate and breathing).

Cannabinoids

Cannabinoids are compounds that interact with the endocannabinoid system. They are found in the cannabis plant (such as THC) or can be produced synthetically in a laboratory (synthetic cannabinoids).

Other stimulants

Other stimulants are stimulant drugs apart from cocaine. They increase heart rate, breathing and energy.

Relevance and key uses of the statistics

Data are collected as part of public health surveillance on substance use in Scotland.

The most up–to–date data available is published in this report to provide a timely indicator of drug trends as part of RADAR, Scotland’s Drugs Early Warning System.

Accuracy

The data are considered accurate.

Data are validated locally by data suppliers/partnerships/sources and checked by PHS.

Where relevant, data quality and completeness issues are described in the text associated with each indicator.

The Code of Practice for Statistics has been followed to ensure a high standard of data value, trustworthiness and quality.

Completeness

Not all data identified for all ED attendances is available for analysis, due to the time required to send and receive toxicology results and to link patient and clinical data.

For quarter 1 of this study:

  • total recruited (unique ED attendances related to illicit drug use): 273
  • completed Castor (clinical notes made by research nurses) data available: 134
  • completed West of Scotland Safe Haven (electronic clinical record) data available: 113
  • toxicology results available: 76
  • toxicology results presented here (as have corresponding Castor data): 38

The testing has been carried out by the LGC Group. LGC analyse pseudonymised samples using mass spectrometry and screen against a database of over 3,500 analytes including illicit drugs, novel psychoactive substances, synthetic cannabinoid receptor agonists, benzodiazepines and medications. We are confident that the compound screen used by LGC is up to date with known drugs and metabolites so will be detected in this study. This analysis does not, however, imply that specific drugs were implicated in harms.

Value type and unit of measurement

Number of ED attendances related to illicit drug use, destination on discharge from the ED, number of hours in the ED, number of hours in hospital, anonymised toxicology results of surplus serum sampling by drug type and drug category.

This study includes patients aged 16 or over attending QEUH adult ED directly related to acute illicit drug use. It excludes patients where the condition is more likely due to a cause other than acute illicit drug use, due to withdrawal, primarily related to alcohol use or where the attendance is due to a complication of previous drug use, i.e. infected injection site.

N/A

Concepts and definitions

Forensic Medicine and Science undertakes toxicology testing on behalf of the Crown Office and Procurator Fiscal Service for post-mortem cases where controlled drugs (as defined in the Misuse of Drugs Act 1971) were found present.

Detailed interpretation of the levels of drugs found present, drug interactions, co–morbidities or other factors relating to death are outside the scope of this analysis.

This analysis does not imply that specific drugs were implicated in deaths nor that deaths were classified as 'drug–related' and does not include consideration of wider causes of death.

Benzodiazepines

Benzodiazepines are a group of drugs with depressant and anxiolytic (anti-anxiety) effects. They are also known as tranquilisers. Diazepam is a ‘prescribable benzodiazepine’. Etizolam, clonazolam and bromazolam are ‘street benzos’, benzodiazepines that are not licensed for prescription in the UK.

Cocaine

Cocaine is a short-lasting stimulant drug that increases heart rate and breathing. This group includes powder cocaine and crack cocaine.

Gabapentin/pregabalin

Gabapentin and pregabalin are gabapentinoids, a group of drugs with depressant and painkilling effects.

Opioids

Opioid drugs act on opioid receptors to produce sedative and painkilling effects. They are respiratory depressants (reduce heart rate and breathing). This category includes buprenorphine, fentanyl, heroin/morphine and methadone.

Relevance and key uses of the statistics

Data are collected as part of public health surveillance on substance use in Scotland.

The most up–to–date data available is published in this report to provide a timely indicator of drug trends as part of RADAR, Scotland’s Drugs Early Warning System.

Where relevant, data quality and completeness issues are described in the text associated with each indicator.

The Code of Practice for Statistics has been followed to ensure a high standard of data value, trustworthiness and quality.

Completeness

The data above are for deaths occurring in the west, east and parts of the north of Scotland. Apart from a very small number of cases analysed at the University of Glasgow, post–mortem toxicology testing for deaths occurring in Aberdeen and the far north of Scotland is conducted by a similar service at the Aberdeen Royal Infirmary (ARI). Results from the ARI are not included in this report.

Concepts and definitions

Benzodiazepines

Benzodiazepines are a group of drugs with depressant and anxiolytic (anti-anxiety) effects. They are also known as tranquilisers. Benzodiazepines detected in this project include etizolam, flubromazepam, bromazolam, diazepam and flualprazolam.

Cocaine

Cocaine is a short-lasting stimulant drug that increases heart rate and breathing. This group includes powder cocaine and crack cocaine.

Gabapentinoids

Gabapentinoids are a group of drugs with depressant and painkilling effects. On average, in this project 16% of gabapentinoid detections are for gabapentin and 84% are for pregabalin.

Opioids

Opioid drugs act on opioid receptors to produce sedative and painkilling effects. They are respiratory depressants (reduce heart rate and breathing). Opioids include synthetic (lab-made) drugs such as methadone and opiates (drugs made from opium) such as heroin. Opioids detected in this project include buprenorphine, heroin, tramadol, codeine, dihydrocodeine, metonitazene, oxycodone and methadone.

Synthetic cannabinoids

'Synthetic cannabinoids' is a term used to describe over 200 lab-made drugs that interact with the endocannabinoid system.

Relevance and key uses of the statistics

Data are collected as part of public health surveillance on substance use in Scotland.

The most up–to–date data available is published in this report to provide a timely indicator of drug trends as part of RADAR, Scotland’s Drugs Early Warning System.

Accuracy

The data are considered accurate.

Data are validated locally by data suppliers/partnerships/sources and checked by PHS.

Where relevant, data quality and completeness issues are described in the text associated with each indicator.

The Code of Practice for Statistics has been followed to ensure a high standard of data value, trustworthiness and quality.

Completeness

Our analysis includes all data provided to PHS by LCRFS. LCRFS does not analysis all seizures from SPS and this data should be considered as a sizeable subset of all national prison seizures.

Comparability

Data are not comparable outwith Scotland.

Release date

24 January 2023

Frequency

Quarterly

Timeframe of data and timeliness

7 August 2020 to 13 November 2022, approximately two months in arrears.

Continuity of data

These data have been extracted from Drug and Alcohol Information System (DAISy) and its predecessor, the Drug and Alcohol Treatment Waiting Times (DATWT) database (both Public Health Scotland). DAISy was available in all NHS Boards from April 2021 (while four NHS Boards were early adopters and transferred to DAISy on 1 December 2020; NHS Ayrshire & Arran, NHS Dumfries & Galloway, NHS Grampian and NHS Western Isles).

Direct comparisons between recent and earlier numbers of referrals recorded in DAISy and the DATWT database respectively, should be interpreted carefully (see revisions statement for further explanation).

Revisions statement

Data in the most recent quarterly updates supersedes data reported in previous reports.

A new continuation of care process was introduced in DAISy which affects how referrals are recorded when people have started treatment and move from one service to another without a break or change in their treatment (for instance, when moving between community-based and prison-based services). Previously in the DATWT database, a referral would have been recorded at both the transferring and receiving service, and the subsequent waiting time for treatment would be recorded at both. In DAISy, if a person is transferred following the continuation of care process, only one wait is recorded, associated with the initial service where the person started treatment, but a referral is recorded for both services. In previous versions of this report these continuation of care referrals were not included. They have been incorporated to improve comparability between DATWT and DAISy.

N/A

Concepts and definitions

These data relate to the number of referrals to specialist drug and alcohol treatment services in Scotland delivering tier 3 and 4 interventions (community-based specialised drug assessment and co-ordinated care-planned treatment, and residential specialised drug treatment). These data are for community-based drug and alcohol treatment services and exclude prison-based services.

An additional ‘co-dependency’ client type was introduced, where the referral relates to treatment for both drug and alcohol use. Co-dependency has only been recorded in all NHS Boards since the introduction of DAISy (April 2021) so is not available as a separate client type in the earlier years. This data is the number of referrals where the client type is recorded as either ‘drugs’ or ‘co-dependency’.

Completeness

Drug and alcohol treatment services are required to submit accurate and up-to-date waiting times information to PHS. These referrals data are management information and includes all services that enter data on DAISy and its predecessor, the DATWT database. (This contrasts with the figures reported in the National Drug and Alcohol Treatment Waiting Times Statistics release for Scotland where data from services that were unable to confirm their data were accurate and up-to-date within specified timescales are excluded). Further details can be found in the substance use section of the COVID wider impacts dashboard.

Concepts and definitions

Defined daily dose

When comparing use between medicines and over time it is common to use World Health Organization (WHO) defined daily doses (DDDs). The DDD is defined as the usual average daily maintenance dose used in adults for the main therapeutic use of the medicine. The WHO DDD is a global average and may not be representative of the doses used in clinical practice at a more local level.

Average daily quantity

Due to differences between the average OST doses used in Scotland and the rest of the world, the analysis presented here is based on average daily quantities (ADQs). These are more representative of the daily maintenance doses used within Scotland and were developed via analysis of prescriptions and by consultation with the Specialist Pharmacists in Substance Misuse group. The ADQs agreed are:

  • methadone (oral): 65 mg
  • buprenorphine (oral): 13 mg
  • buprenorphine (parenteral/injectable): 3.4 mg

Buprenorphine

Buprenorphine is a synthetic partial opioid agonist used to treat acute pain, chronic pain and opioid dependence. Prescribed for daily use (oral) or weekly or monthly prolonged release (injectable), buprenorphine relieves opioid cravings and withdrawal symptoms and blocks the effects of other opioids. As with other opioids, buprenorphine can result in sedation, respiratory depression and death. These statistics relate to the prescribing of oral (2 mg, 8 mg and 16 mg buprenorphine or buprenorphine and naloxone tablets) and injectable buprenorphine (various strengths) for the treatment of opioid dependence.

Opioids

Opioid drugs act on opioid receptors to produce sedative and painkilling effects. They are respiratory depressants (reduce heart rate and breathing). Opioids include synthetic (lab-made) drugs such as methadone and buprenorphine, as well as opiates (drugs made from opium) such as heroin and morphine.

Methadone

Methadone is a synthetic opioid agonist used to treat chronic pain and opioid dependence. Prescribed for daily use, methadone relieves opioid cravings and withdrawal symptoms. As with other opioids, methadone can result in sedation, respiratory depression and death. These statistics include data on the prescribing of methadone 1mg/1ml solution for the treatment of opioid dependence.

Relevance and key uses of the statistics

Data are collected as part of public health surveillance on substance use in Scotland.

The most up–to–date data available are published in this report to provide a timely indicator of drug trends as part of RADAR, Scotland’s Drugs Early Warning System.

Accuracy

The data are considered accurate.

There are differences between community prescribing data (PIS) and hospital prescribing data (HMUD) in the way that dates are allocated to medications supplied. The basis for date allocation in PIS data is the month in which the costs associated with dispensing medication are reimbursed. The basis for date allocation in HMUD data is the month in which medications are supplied for onward administration to patients. While useful to note, these differences are not thought to have a significant impact on the reliability of this analysis.

Data are validated locally by data suppliers/partnerships/sources and checked by PHS.

Where relevant, data quality and completeness issues are described in the text associated with each indicator.
