Thoroughly updated with the latest research, social trends and legal changes, Maisto/Galizio/Connors DRUG USE AND MISUSE, 9th Edition, takes an interdisciplinary approach in its comprehensive coverage of current drug issues. Weaving historical, social, psychological, cultural, biological and medical perspectives, it emphasizes the idea that a drugs effects depend not only on its properties, but also on the psychological and biological characteristics of its user. Highlighted throughout, this theme is prominent in discussions of the individual classes of drugs and in the chapters on pharmacology and psychopharmacology. The 9th Edition includes the most current survey data available on patterns of drug use as well as new section-review activities, end-of-chapter essays and critical thinking questions.
