Description
Summary:Objective: To determine the prevalence of licit and illicit substance use among male and female prisoners of Karachi jails, and the association between substance use and the type of crime committed. Study Design: A descriptive cross-sectional study. Place and Duration of Study: This study was conducted among male and female prisoners in Malir and Central Jail, Karachi, Pakistan from April 2020 to September 2020. Methods: A cross-sectional survey was conducted among 700 males and females aged 18-60 from Central and Malir Jail, Karachi, Pakistan. The sample population was selected using a convenience sampling technique. The prevalence and type of substance use were assessed using the WHO Questionnaire. Chi-square was applied to identify the association between drug use and criminal profile. Results: Male prisoners were more likely to have ever used tobacco compared with females (91.5% vs 34.0%) followed by cannabis (55.0% vs 2.0%) and opioids (25.8% vs 2.0%). Overall, current substance use during imprisonment was relatively less than lifetime use of substance before imprisonment. However, the types of substance used remained unchanged. During imprisonment, Tobacco was currently the most common substance of use among males (85.2%) and females (27%). A significant association was observed between ever drug use and type of crime committed (P<0.001). Conclusion: The current study demonstrated a higher prevalence of lifetime substance use compared to the prevalence of current substance use; however, the type of drugs was not specified. However, the type of drug use remained consistent. A predominant consumption of tobacco, cannabis, and opiates was found among male prisoners, and high consumption of tobacco was found among female prisoners. Respectively, 95.1% and 91.6% of inmates imprisoned for drug-related crimes and unlicensed weapons were drug users. How to cite this: Jamal M, Waheed S, Shakoor A.
