In this completely revised and updated third edition of his highly successful book, Hamid Ghodse presents a comprehensive overview of substance misuse and dependence. There is a particular 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 he has written an entirely new chapter on alcohol abuse. He 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. This will be essential reading for all clinicians and other professionals dealing with addiction, from counsellors and social workers to policy makers.
