Tobacco, cannabis, and alcohol consumption, found to be most common among college students, is known to cause life-threatening diseases, and is correlated with social, financial and health problems. For the present study, we aimed to assess the sociodemographic factors affecting tobacco, alcohol, and cannabis consumption among university students. A cross-sectional study was conducted from January to March 2020, on a random sample of 507 undergraduates, between the ages of 18 and 24. The research instrument was a self- administered questionnaire with questions on the sociodemographic characteristics, and questions regarding the consumption of tobacco, alcohol, and cannabis.

The mean ± standard deviation age of study sample was 21.56 ± 1.81 years, and 56.4% participants were females. The lifetime prevalence of tobacco usage among the study sample was 66.7%, alcohol 54.2%, and the cannabis had a prevalence of 13.8%. About 46.2% (n = 234) were co-users of tobacco smoking and alcohol, and 12.6% (n = 64) were co-user of tobacco smoking, alcohol consumption, and drug use. Analyzed with Pearson's chi-squared test, there was no statistically significant difference between students from private and public institutions on lifetime, in the past 1 year/1 month of tobacco smoking, alcohol consumption, and cannabis use (p > 0.05). The logistic regression model for dependent variable cannabis abuse in the past 1 year is associated with lower odds among female students (odds ratio: 0.337, 95% confidence interval: 0.167–0.682; p = 0.002). Smoking, drinking, and cannabis were found to be highly prevalent among university students. These findings can help program managers and policy makers devise effective and appropriate control programs and policies for substance-using university students.
