Posttraumatic stress disorder (PTSD) is a common co-occurring diagnosis in patients with substance use disorders (SUDs). Despite the documented prevalence of this particular "dual diagnosis," relatively little is known about effective treatment for SUD-PTSD patients. This article reviews empirical research on the course and treatment of SUD-PTSD comorbidity and highlights clinically relevant findings. Based on this review, the following is noted: PTSD is highly prevalent in SUD patients, consistently associated with poorer SUD treatment outcomes, and related to distinct barriers to treatment. Specific treatment practices are recommended for substance abuse treatment providers: (a) All patients should be carefully screened and evaluated for trauma and PTSD; (b) referrals should be provided for concurrent treatment of SUD-PTSD, if available, or for psychological counseling with the recommendation that trauma/PTSD be addressed; and (c) increased intensity of SUD treatment should be offered in conjunction with referrals for family treatment and self-help group participation.
