Drug use among university undergraduate students.

A sample of 457 undergraduate university students were surveyed to assess their current use of illicit drugs. Such information is to be used as a baseline to examine the effectiveness of drug prevention programs designed for this population. Marijuana was the most common illicit drug used among these students, and men were significantly more likely to report use. Age differences were noted; older students (age greater than or equal to 22 yr.) were more likely to report drug use than those students under 22 years of age. The age differences suggest that there may be a shift away from drug use among the younger students. The low over-all rate of drug use may make difficult the evaluation of prevention programs.
