This is a recovery workbook that provides clients with practical information and skills to help them understand and change their problems with alcohol, tobacco, or other drugs, such as marijuana, cocaine or methamphetamine, heroin or fentanyl, or nonprescribed addictive medications. The workbook is designed to be used in therapy or counseling and will help to focus on specific issues involved in stopping substance use and in changing behaviors that keep substance use problems active. The information presented is derived from research, clinical and recovery literature, and the authors’ many years of experience working with clients who have alcohol, tobacco, and other drug problems. It discusses the most effective and helpful recovery issues and change strategies from studies of cognitive-behavioral treatment, coping skills training, 12-step counseling, and relapse prevention. These treatment approaches focus on the importance of changing beliefs, thinking, relationships, and behaviors and learning skills to help clients stay sober and change their lives. The goals of this workbook are to help clients reach maximum treatment benefit by motivating them to develop and implement a personal change plan and to provide them with practical strategies and skills to cope with the most common problems and challenges encountered when substance use is stopped.
