Study participants will be 15- to 17-year-old youth recruited from Facebook/Instagram. All youth will complete pretest measures online. Intervention-arm youth will then interact with the 9-session program; youth in the control arm will have access to an attention-placebo website. All youth will then complete posttest measures (immediately following intervention completion and estimated to be approximately 5 months after study onset) and 1-, 2-, and 3-year follow-up measures.\n\nAcross posttest and annual follow-up measurement occasions, data analyses will examine rates of 30-day drug use between study arms. The investigators will also examine intervention effects on mediator variables associated with drug use and assess the extent to which changes in mediator variables explain differences in drug use between arms.\n\nYouth assigned to the intervention arm will have access to 9 intervention sessions delivered online. The sessions will be housed on a website with entertainment features youth seek: life hacks, features on LGBTQ leaders, fortunes, horoscopes, inspiring quotes, and health-related resources.\n\nTo ensure that youths' expectations for study participation are equivalent across arms and to account for the non-active components of the experimental intervention, the investigators designed the attention-placebo arm.
