Multiple Drug Use Among Marijuana Smokers in Eastern Canada

Abstract

Emphasis has recently shifted from an almost exclusive focus on the social and psychological characteristics of those who use particular drugs to special consideration of the users' relationships to the use of other substances. It is only proper that this should be the case. The clearest datum that emerges from studies of drug use is that those who use any one drug are more likely to use any other drug than those who do not use that drug The important questions are the following (a) what is the magnitude of this relationship?; (b) with what other drugs is this relationship strongest?; and (c) what is the significance of this relationship?
