Cocaine and Heroin Dependence Compared: Evidence form an Epidemiologic Field Survey.

Abstract: Analyzing self-report interview data from a multi-site collaborative study of mental disorders in the community, we examined suspected differences between 611 cocaine users and 126 heroin users in relation to indicators of drug dependence. Cocaine users were less likely to report dependence-related problems as compared to heroin users. These epidemiologic sample data underscore concerns about the generalizability of published clinical sample data on self-reported cocaine dependence. [ABSTRACT FROM AUTHOR]
