Peer influence processes as mediators of effects of a middle school substance use prevention program.

CONCLUSIONS: Cooperative learning was able to significantly reduce the prevalence of both alcohol and tobacco use in friendship networks during the school year. The lower prevalence of alcohol and tobacco use among friends, in turn, reduced individual use at follow-up. This study was registered as trial NCT03119415 in ClinicalTrials.gov.
