Sophia F. Dziegielewski draws on her many years as a teacher and practitioner to put together this accessible, well-thought-out overview on a variety of substance addictions and disorders, the people who suffer from them, and the tools available to help them. Each chapter was written specifically for this book by a unique blend of academics and practitioners. Their combined experiences contribute to making this book practical, easy to read, and thoroughly helpful in diagnosing substance disorders. This book may be used in a variety of courses including drug, alcohol, and substance abuse courses taught in social work and human services departments, and substance abuse certificate programs.
