OBJECTIVE To assess the prevalence of illegal drug use in college students on any previous occasion, during the previous year and the previous month, and to analyze the relationship between illegal drug use and family support and other factors. METHODS A cross-sectional study using data from students participating in the uniHcos project (n = 3767) was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives, stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent variables were: family support, age, residence, and employment status. To determine the factors related to drug use multivariate logistic regression models stratified by gender were fitted. RESULTS Differences between men and women in prevalence of illegal drug use except non-prescription sedatives were observed. In both genders, less family support was associated with higher consumption of all drugs, except depressants, and with polyconsumption. To be studying and looking for work was related to cannabis and stimulant use and to polyconsumption among women, but only to cannabis use among men. CONCLUSIONS These results support the notion that the start of university studies is a particularly relevant stage in the onset of illegal drug use and its prevention, and that consumption may be especially associated with family support.
