Long-term behavioral effects of a school-based prevention program on illicit drug use among young adults

Most universal drug abuse prevention efforts target early adolescents with the goal of delaying or preventing the onset of substance use. The present study examined long-term follow-up data from a large-scale randomized trial of a school-based prevention program that used cognitive-behavioral skills-training techniques to enhance social and personal competence skills and drug refusal skills. The preventive intervention was implemented in junior high schools, and pretest data were collected from students in the classroom. Approximately 13 years later, follow-up data were collected by mail from 2042 young adults. Rates of overall lifetime illicit drug use, as well as lifetime marijuana use, marijuana intoxication, and lifetime non-medical pill use, were lower among students who received the prevention program (Life Skills Training) during junior high school compared to control group participants. These findings support the hypothesis that comprehensive, universal school-based prevention programs can produce long-term effects on illicit drug use behavior.
