Correlates of adolescent drug use by gender and geographic location

We examined the correlates of self-reported lifetime use of alcohol, marijuana, amphetamines, and cocaine within a sample of almost 7,000 high school sophomores in Arizona and Utah. Correlates of drug use (including parental attachment, religious attachment, educational attachment, conventional values, and drug-using friends) showed very similar patterns by gender, with some interesting differences by location. Drug-using friends are by far the best predictor of drug use for both males and females in Arizona and Utah.
