Criminal activities account for a major proportion of the social costs related to illicit drug use. This article examines the factors contributing to property crime activity among a community sample of 653 untreated regular illicit opiate users in 5 Canadian cities (OPICAN study). Multivariate analyses showed the frequency of heroin, cocaine, and crack use, gender, housing status, and past criminal justice involvement as predictors of property crime. Furthermore, crack use had a significantly different impact on property crime depending on housing status and city. These findings underline the need for targeted intervention efforts toward a reduced crime burden.
