Prisoners have significantly greater levels of drug use than the general population, which is related to many adverse outcomes both during and post-imprisonment. Reducing the availability of drugs in prison can lead to a reduction in the drug use of prisoners but requires knowledge of the different drug smuggling routes and the implementation of effective security measures. The main smuggling routes identified in the literature are through visitors; mail; prisoners on reception, remand, or work release; staff; and perimeter throwovers, but they differ between prisons depending on various contextual factors and security measures in place. Based on a total of 81 studies from 22 different countries, the average prevalence of drug use during incarceration is 32.0% with a range from 3.4% to 90%. The types of drugs used in prisons vary among geographical regions, countries, and even regions within countries. The most common drug reported to be used by prisoners in most studies was cannabis, except in South Asia and Scotland, where heroin was more prevalent. The drugs used in prison tend to reflect the prevalence of drugs in the local community, except where a drug has advantages unique to use in prison. It is vital to examine the prevalence of drug use and different types of drugs used during incarceration to help inform drug treatment services, assist prison staff in identifying potential drug use or intoxicated prisoners, and advise prisons about the most prevalent drug smuggling routes so new security measures can be considered.

This European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) Insights report provides a comprehensive overview of the current knowledge and latest developments in the field of drug use and prison in the 30 countries reporting to the EMCDDA up to the end of 2020: the 27 EU Member States, Norway, Turkey and the United Kingdom. It also identifies important gaps in our knowledge, challenges for better provision of interventions and implications for policy and practice. The report provides an overview of the current situation in the field of drugs and prison in the following areas: drug use and drug-related problems among the prison population; the availability of drug-related services in prison; the evidence available for effective interventions in the prison setting; drug supply and supply reduction interventions; and future challenges relating to prison and drugs.

People in prison report high levels of lifetime prevalence of substance use before imprisonment and increased levels of consumption, especially of heroin, cocaine and amphetamines, compared with the general population. Although many people will stop injecting drugs when they enter prison, for those that continue, the use and reuse of contaminated equipment is not uncommon, contributing to an increased risk of transmission of infectious diseases in these settings.
