Sponsored by University of Washington · Phase 2, Interventional, and Treatment
This behavioral research is an efficacy trial evaluating an intervention called "The Teen Marijuana Check-Up" with non-treatment seeking adolescent marijuana users.
Three hundred adolescents who smoke marijuana (ages 14-19), recruited in four Seattle-area high schools, will be enrolled in the trial. Participants will be recruited either through in-class presentations focusing on marijuana or via referrals from school staff. They will first be assessed regarding use of marijuana, alcohol, and other drugs, as well as pertinent attitudes and goals. Participants will then be randomly assigned to one of three conditions.
Following completion of their two intervention sessions, participants in the two active treatments will be offered an additional four sessions of cognitive-behavioral skills training in which the focus is strategies in quitting marijuana. All participants will be reassessed at 3 and 12 months following their initial assessment interviews.
