CONCEPTS OF CHEMICAL DEPENDENCY, 10th Edition, provides comprehensive coverage and the latest information on a spectrum of substance use disorders and the compounds commonly misused. Author Harold Doweiko also covers topics not usually discussed in other substance abuse texts, including anabolic steroids, inhalants, infectious diseases associated with substance misuse, the medical marijuana 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 synthetic drugs, updates reflecting new preferred language in referring to those who struggle with substance use disorders and a new chapter on substance use and misuse in older adults.
