The dynamic nature of the drug use/serious violence relationship: a multi-causal approach.

Relying on historical research, a longitudinal data set, and multivariate analyses, the drug-violence relationship is scrutinized. A proposed model is tested and supported, indicating that attitudes toward violence, gender, neighborhood problems, minor delinquency, and victimization were persistent correlates that must be considered within the drug-violence relationship. Parental attachment and importance, exposure to delinquent peers, and drug dealing were also important.
