Comparative study of drug use among undergraduate students at the University of São Paulo: São Paulo campus in 1996 and 2001
OBJECTIVE: To compare the rate of drug use prevalence and to investigate opinions regarding such use among undergraduate students at the University of São Paulo - São Paulo campus in 1996 and again in 2001. METHODS: Both studies followed the same procedures of sampling and data collection. A random sample of undergraduate students, divided into the areas Humanities, Exact Sciences and Biologic Sciences, responded to an anonymous and self-report survey regarding the use of licit and illicit drugs within the last 30 days, within the last 12 months and over the lifetime of the subject. The two surveys were compared through the construction of (95%) confidence intervals for the prevalence differences for each substance by area and by total number of students. The Wald test for homogeneity was applied in order to compare the prevalences. RESULTS: High approval of regularly trying and using cocaine, crack, amphetamines and inhalants was observed. The drugs that showed statistic significant increasing were:lifetime use: alcohol, tobacco, marijuana, inhalants, hallucinogens, amphetamines, anticholines, barbiturics and any illicit drug;last-12-month use: marijuana, inhalants, amphetamines, hallucinogens and any illicit drug;last-30-day use: marijuana, inhalants, amphetamines and any illicit drug. DISCUSSON: The observed difference in the use of some drugs between the two surveys appears to be a consequence of the higher rates of favorable opinions regarding trying and regularly using some psychoactive substances, a finding that mirrors global trends in drug use.
