The research also focused on whether the number of risk factors present also has an effect on the different dimensions of juvenile drug use. Results of multivariate logistic regression analyses revealed that the effects of family disruption, conflict in the family, parental monitoring, academic performance, time spent with friends, and peer deviance differed significantly across the various dimensions of drug use studied.
