Objective: To determine the prevalence of substance use disorders among inmates in a Sri Lankan prisonMethod: A semi- structured interviewer administered questionnaire and ICD 10 clinical diagnostic criteria were applied to 410 randomly selected male and female prisoners in minimum/medium security settings in the largest prison in Sri Lanka.Results: 75.6% (95% CI 71.2 – 79.5) of prisoners had lifetime substance use disorder while 24.4% (95% CI 20.2– 28.6) met criteria for current substance use disorder. 56.8% and 67 % of participants met criteria for lifetime alcohol and tobacco use disorders, respectively, while and 42 %and 25.6% had lifetime cannabis and opioid dependence, respectively. Factors significantly associated with lifetime substance use disorder were male gender, residence in an urban area, younger age and being unemployed or having only temporary employment. 23% of participants who met criteria for dependence were intravenous substance users.Conclusions: Services should be improved in the prison health system to minimize harm from substance use disorders.
