Substance use is a global phenomenon that is particularly affecting the prison population. This study aimed to describe the prevalence of drug use among people in prison before and during incarceration in seven European countries and to compare it with the prevalence in the general population. Individual data collection was carried out between 2014 and 2018 with a model European Questionnaire on Drug Use among people in prison. A total of 12,918 people living in prison filled in the survey. People in prison report higher level of drug use when compared with the general population and the use of drug inside prison exist, although at lower levels when compared with predetention. Prisons can represent a point of access to engage individuals who use drugs in interventions that address drug use and risk factors related to both drug use and imprisonment.

Background: Many people who enter prison have recently used drugs in the community, a substantial portion of whom will continue to do so while incarcerated. To date, little is known about what factors may contribute to the continuation of drug use during imprisonment. Methods: Self-reported data were collected from a random sample of 1326 adults (123 women) incarcerated across 15 prisons in Belgium. Multivariate regression was used to investigate associations between in-prison drug use and sociodemographic background, criminological profile, drug-related history, and mental health among participants who reported pre-prison drug use. Results: Of all 1326 participants, 719 (54%) used drugs in the 12 months prior to their incarceration and 462 (35%) did so while in prison. There was a strong association between drug use before and during imprisonment (OR = 6.77, 95% CI 5.16–8.89). Of those who recently used drugs in the community, half (52%) continued to do so while incarcerated. Factors independently associated with continuation (versus cessation) were young age, treatment history, polydrug use, and poor mental health. In a secondary analysis, initiation of drug use while in prison was further related to incarceration history and low education. Conclusion: Persistence of drug use following prison entry is common. People who continue to use drugs inside prison can be differentiated from those who discontinue in terms of drug-related history and mental health. Routine screening for drug use and psychiatric morbidity on admission to prison would allow for identifying unmet needs and initiating appropriate treatment.
