Substance use-and abuse-has existed in virtually all cultures throughout human history. Canada is no exception, but what may come as a surprise are the rates and the specific substances themselves that are most liable to abuse in this country. In an accessible and engaging style, this short book presents the latest research, survey, and interview data on substance abuse, taking into account Canada's regional differences and demography. It describes the models used by experts to explain substance abuse and addiction, and evaluates the various social policy, psychological, and medical solutions.
