This completely revised and updated third edition presents a comprehensive overview of substance misuse and dependence. The volume places a special emphasis on practical, evidence-based approaches to the assessment and management of a wide range of drug-related problems in a variety of clinical settings, and includes an entirely new chapter on alcohol abuse. The author defines all the terms and describes the effects of substance misuse on a patient's life. Epidemiology, and international prevention and drug control policies are covered to address the global nature of the problem, and the appendix provides a series of clinical intervention tools, among them a Substance Misuse Assessment Questionnaire.
