Doweiko/Evans' CONCEPTS OF CHEMICAL DEPENDENCY, 11th EDITION, provides comprehensive coverage and the latest information on a spectrum of substance use disorders and the substances commonly misused. Author Amelia Evans, continuing Harold Doweiko’s work on prior editions, also covers topics not usually discussed in other substance use disorder texts, including anabolic steroids, inhalants, infectious diseases associated with substance misuse, the medical cannabis debate, and how the "war on drugs" has contributed to the problem of substance use disorders. Students report that they appreciate the balanced approach, which allows them to form their own opinions and doesn't preach that "drugs are bad for you." This edition includes new information on recent reports expanding beyond the United States and updates reflecting new preferred language to reduce stigma. It also has a perspective beyond the United States for a more worldwide understanding of substance use disorders.
