Substance use and related disorders among persons exposed to the 9/11 terrorist attacks: Essentials for screening and intervention.

A growing body of research supports the association between direct exposure to the September 11, 2001, terrorist attacks, increased rates of alcohol and substance use and elevated risk of subsequent diagnosis with trauma-related and substance use disorders. Posttraumatic stress disorder (PTSD) is the most diagnosed psychiatric illness in individuals who witnessed the 9/11 attacks or participated in disaster response efforts, and substance use disorders (SUDs) are highly comorbid with PTSD. The presence of both conditions poses challenges for clinical management and highlights the importance of screening and offering intervention to this at-risk population. This paper provides background on substance use, SUDs, and co-occurring PTSD in trauma exposed populations, describes best practices for identifying harmful substance use, the role of psychotherapy and medication for addiction treatment (MAT), and recommendations for management of co-occurring SUD and PTSD.
