This book serves as a tool for general psychiatrists, medical students, residents, and fellows looking for a clinically relevant and high-yield overview of addiction psychiatry in preparation for their board exams – or for everyday clinical practice.  Written by expert educators in addiction psychiatry, the text is organized by substances misused and populations affected. This book serves as both a primary learning tool for those new to the field, as well as a reference for those working in addiction treatment. Each chapter begins with summaries of high yield clinical pearls, followed by general information including treatment, and then ends with accompanying board-style review questions. The scope includes understanding substances of misuse and substance use disorders (SUDs), how to evaluate, diagnose, and monitor SUDs, how to treat SUDs both pharmacologically and behaviorally, and critical information for specific populations of patients.   Absolute Addiction Psychiatry for Clinical Practice and Review is an excellent resource for all medical students, residents, fellows, and professionals taking certification exams in addiction, including those in psychiatry, addiction medicine, emergency medicine, internal medicine, pain medicine, and others.   The chapter "Laboratory Testing for Substance Use Disorders" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
