Clinical Characteristics of Cannabis Use Disorder

Abstract

This chapter reviews the signs and symptoms of cannabis use disorder (CUD). Core clinical characteristics of addiction as reflected by the fourth and fifth editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM) apply to cannabis, although certain substance use disorder symptoms are less salient to cannabis relative to other substances. The chapter addresses cannabis use prevalence, onset and progression of cannabis use, and heterogeneity in the course of cannabis use. The core features of addiction and the DSM CUD diagnosis are described with reference to the prevalence of CUD based on the fourth edition of the DSM, differences between the fourth and fifth editions for the criteria for diagnosis, and DSM-based cannabis symptoms. The course of CUD and remission and recovery from CUD are also addressed. The chapter closes with a discussion of research and treatment gaps.
