Abstract: 

This study is a continuation of 3 previous NIDA-funded projects that developed and evaluated the acceptability and preliminary efficacy of a brief intervention (The Teen Marijuana Check-Up) intended to attract voluntary participation from adolescents who smoke marijuana. The interventions are designed to provide adolescents who are not seeking treatment with an opportunity to weigh the pros and cons of smoking marijuana through the provision of objective information regarding marijuana use. The present study will evaluate the efficacy of this intervention with an adequate sample size to determine its impact on adolescent marijuana use and readiness to change.
