Substance Use Disorders provides an overview of substance misuse and addresses the neurobiology, pharmacotherapy, and behavioural therapy management of substance use disorders from a clinical perspective. Examining the opioid epidemic to frame its discussion of the epidemiology of substance misuse, this book explores common barriers that prevent the implementation of effective treatment. Chapters discuss various aspects of substance use disorders, particularly opioids, alcohol, cannabis, and cocaine, to inform better conceptualization and management of these conditions. Part of the Primer On Psychiatry series, this book will provide a solid foundation for residents and fellows in psychiatry and addiction medicine and can also be used in clinical practice.
