The role of schools in substance use prevention and intervention.

Schools provide an ideal setting for screening, brief interventions, and outpatient treatment for substance use disorders (SUD). Individual treatment for SUD is effective at decreasing substance use as well as substance-related harm. In some contexts, rather than being helpful, group interventions can result in harm to participants; therefore, individual treatment may be preferred. Early interventions for adolescents who are using alcohol and other drugs (AOD) are generally effective in decreasing frequency and quantity of AOD use as well as decreasing risky behaviors.
