Explaining the link between violence perpetration, victimization and drug use.

This study examined relationships between illegal and legal drug use and violence perpetration and victimization as well as possible mediators of these relationships. Subjects were continuation high school students followed prospectively over 5 years. Results indicated that illegal drug use predicted violence and victimization 5 years later and that earlier victimization was also associated with later illegal drug use. A measure intending to tap a psychopharmacological effects system, consistent with its definition in [Goldstein, P. J. (1985). The drugs/violence nexus: A tripartite conceptual framework. Journal of Drug Issues, 15(4), 493-506] tripartite model, was found to mediate the relationships between illegal drug use and victimization and violence. Results suggest that violence and victimization prevention efforts may benefit by addressing the psychopharmacological effects of adolescent illegal drug use.
