This part presents a range of information on illicit drug use among adults including the prevalence of drug use, the number of people receiving treatment for drug addiction, comparisons across European countries and information on new psychoactive substances (previously known as legal highs).
The main source of data for drug use among adults is the Drug misuse: findings from the Crime Survey for England and Wales published by the Home Office. This is an annual publication covering the prevalence and trends of illicit drug use among 16 to 59 year olds including separate analysis on young adults (16 to 24). Illicit drug use excludes new psychoactive substances, and nitrous oxide from the drug use prevalence figures, but these are covered separately in the survey.
Information on drug dependence is taken from the NHS Digital Adult Psychiatric Morbidity Survey: Survey of Mental Health and Wellbeing, England. This survey has been run every 7 years since 1993, with the last one having taken place in 2014.
Information on treatment for drug misuse is taken from Public Health England’s alcohol and drug misuse treatment publications, which are based on data from the National Drug Treatment Monitoring System (NDTMS).
Comparisons of drug use prevalence across European countries is taken from the European Drug Report –Trends and Developments, published by the European Monitoring Centre for Drugs and Drug Addiction.
