The relationship of preaddiction characteristics to the types and amounts of crime committed by narcotic addicts.

Postaddiction crime rates among narcotic (principally heroin) addicts in five different areas (theft, violence, dealing, confidence games, and other crime) were found to be substantially related to a number of preaddiction characteristics, especially criminal activity and drug and alcohol use prior to addiction to narcotics. Early family influences such as lack of religious training, history of parents' arrest, and use of drugs and alcohol by other family members also appear to play an important role. Early identification of extremely crime-prone individuals followed by intensive intervention efforts might reduce the amounts of crime such persons might otherwise commit.
