Welcome to the Companion website!

This site is intended to enhance your use of Substance Use Disorders and Addictions by Keith Morgen. Please note that all the materials on this site are especially geared toward maximizing your understanding of the material.

Based on a decade of research and theory, Substance Use Disorders and Addictions examines co-occurring psychiatric disorders as the norm with substance use disorders and addictions. With more than 20 years of experience in the field as a clinician, a researcher, a program developer, and an instructor, Keith Morgen encourages a holistic approach to working with individuals, using a single case example throughout the text to encourage the sequential application of concepts to co-occurring disorders. With DSM-5 diagnostic criteria, the 2014 ACA code of ethics, and 2016 CACREP standards integrated throughout, readers will benefit from this applied and cutting-edge introduction to the field.


We gratefully acknowledge Keith Morgen for writing an excellent text and creating the materials on this site.
