Description

This is a school-based program to prevent the abuse of psychoactive substances by high school students who exhibit violent behaviors and are at risk when it comes to drug abuse.
Classes are taught by trained health educators, who administer the curriculum over a three-week period. Each session lasts 40 minutes and takes place during class time.
The first version of the program develops nine sessions focused on: communication and active listening, stereotypes, myths and denial, chemical dependency, motivational interviewing, stress, health and goals, self-control, perspectives, and decision-making and commitment.
The second version of the program includes three more specific sessions dealing with cannabis use, the links between positive and negative thinking and subsequent behavior, and quitting smoking tobacco.

Impact evaluations

Impact evaluation studies showed that the program produced no statistically significant effects on cannabis use, cocaine use, or prevalence of drunkenness, and mixed effects on tobacco use, alcohol use, and hard drug use. There was a statistically significant improvement for the treatment group in overall substance use and in the index of use of all hard drugs [1] [2] [3].
