Substance‐Related Disorders

Abstract

The substance‐related disorders category encompasses a wide range of conditions associated with legal and/or illegal substance use. Substance‐related disorders fall broadly into two categories: substance use disorders , characterized by dependence and/or abuse, and substance‐induced disorders , which involve intoxication or withdrawal. This entry begins with a brief overview of the clinical features of substance use and substance‐induced disorders in both adolescents and adult populations. Epidemiological data on the prevalence of substance‐related conditions are then summarized and the literature regarding both the development and clinical course of treatment is reviewed. Subsequently, risk factors for substance use and abuse are outlined, along with protective factors that attenuate risk for substance‐related disorders. The final section describes evidence‐based treatment approaches for substance‐related conditions.
