Given the prevalence of alcohol and cannabis co-use among college students, prevention for co-use is crucial. We examined hypothetical receptiveness to substance-specific interventions among students who reported co-use. Students who use alcohol and cannabis were more receptive to alcohol interventions than cannabis interventions. Campus…

Objective: To describe an iterative approach to developing an online intervention targeting the intersection of alcohol use and sexual behaviors among first year college students.

Alcohol use, especially heavy or binge-drinking behavior, among college students continues to be an area in need of prevention and effective clinical intervention. With the myriad of known consequences that are associated with problematic and risky drinking, it is crucial that there are evidence-based programs available and offered to college…

An earlier trial of a school-based, preventative intervention, HealthWise South Africa, demonstrated some efficacy in preventing adolescent drinking and smoking in the Western Cape, South Africa. This was followed by the current implementation trial, which examined how implementation support conditions influenced adolescent drinking and smoking…

We report the results of a quasi-experimental evaluation of a mystery shopper intervention in Zacatecas and Guadalupe, Mexico.
