Psychoactive Substance Use among Second-Year and Third-Year Medical Students of a Medical College: A Descriptive Cross-sectional Study

INTRODUCTION: Psychoactive substance use among medical students is common. This may not only pose a threat to their health and academic performance but may have medico-legal and ethical ramifications. The aim of this study was to find out the prevalence of six psychoactive substances (alcohol, tobacco, cannabis, cocaine, benzodiazepines, opioids) among second year and third year medical students. METHODS: A descriptive cross-sectional study was done in a medical college. Whole sampling was done and ethical approval was taken from the Institutional Review Committee (Reference Number: 54-074/075). The study was conducted from May 2018 to June 2018. A semi-structured self-administered questionnaire modified and adapted from World Health Organization's guidelines for student substance use survey was used to collect data from second year and third year medical students. Statistical Package for Social Sciences version 16.0 was used for analysis. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: Out of 226 total respondents, 95 (42.0%) (35.55-48.45 at 95% Confidence Interval) reported current use of one or more psychoactive substances. Most frequently used substance was alcohol with current use prevalence of 87 (38.5%), followed by smoking 39 (17.3%) and cannabis 27 (11.9%). Cocaine, benzodiazepines and opioids were the least consumed substances with current use prevalence of 2 (0.9%) each. CONCLUSIONS: Almost half of the students were currently using one or more psychoactive substances which is concerning, and therefore strategies must be adopted to alleviate such use.
