Predictors of substance use at school among high school students

Although many studies have examined the predictors of overall substance use among adolescents, few have focused on the high school setting as a specif ic context for substance use. Therefore, predictors of alcohol and marijuan a use at school were examined in a sample of high school students. The gene ral hypotheses were that substance use at school depends on (a) personal pr edispositions, (b) the situational opportunity for substance use at school, and (c) the interaction of predispositions and opportunity. Several intera ctions were found suggesting that personal predispositions are more strongl y related to substance use at school when students believe they have the op portunity to use alcohol and drugs without getting caught.
