Trauma and Substance Abuse offers a broad overview of current trends in the field of co-occurring substance abuse and PTSD from both clinical and research perspectives. The goal of this volume, newly revised to include special settings, such as court systems and disasters, and special populations, such as veterans, is to clarify issues specific to trauma, PTSD, and substance abuse and to translate both quantitative and qualitative data into specific recommendations for clinicians, researchers, and administrators.
