The National Association of State Alcohol and Drug Abuse Directors (NASADAD) conducted an environmental scan of the training, outreach, and resources offered by the Single State Agencies (SSAs) in charge of drug and alcohol treatment and prevention services to respond to the needs of returning veterans and their families. This scan was conducted to learn how to more effectively serve returning veterans and family members impacted by substance use disorders (SUDs). To accomplish this, NASADAD conducted case studies of nine states that had been identified as having the largest number of initiatives for returning veterans. This book examines the data for these case studies which were gleaned from 36 interviews with SSA staff and staff from publicly funded SUD treatment facilities. NASADAD staff gathered data on state policies, trainings, and outreach efforts, as well as recommendations for future development of technical assistance and training materials to address the gaps in services.
