How far can you go? Association between illicit drug use and academic migration

Objective: To measure the prevalence of illicit drugs use in the lifetime, last year and last month, as well as the factors associated to the last year's use and its association with academic migration, among undergraduate students of a university in southern Brazil. Methods: In this cross-sectional study, data were collected through self-administered questionnaire. It was conducted a clustered systematic sampling. For multivariate analyses, it was used Poisson regression. Results: 1,423 students participated. The prevalence of illicit drug use in the lifetime, last year and last month were 42.4%, 25.5% and 17.7%, respectively. Regarding illicit substances, marijuana use was the most prevalent. The variables independently associated with illicit drugs use in the last year were academic migration, being male, younger, single, high parent's educational level, living with peers, tobacco use in the last year, and having friend and relative that have used illicit drugs. Religious practice had a protective effect. Conclusion: Individuals who migrated from their cities to study at the university are more exposed to the main risk factors pointed out by this research and hence to the use of illicit drugs. Based on these results, we suggest that universities develop evaluation, prevention, treatment or referral strategies considering specific needs of this population
