This book is part of the Forensic Practice Guidebooks series published by the American Psychological Association. One may question the need to even consider a book written about substance abuse treatment, since many already exist. Moreover, for more than a decade organized medicine has officially recognized the subspecialties of addiction psychiatry and forensic psychiatry, and an important work at the intersection of these two psychiatric subspecialties would have been anticipated. Curiously, however, the professional literature lacks a current comprehensive critical review on the topic of treatment of criminal offenders with substance use disorders.
