This course is designed as an introduction to the study of substance use and addiction. Current research in the pharmacology and physiology of addictive processes is considered as well as current models for understanding chemical dependence, recovery and relapse. Students learn how the addictive process is assessed and professionally treated and how treatment is individualized based upon the physical, emotional and social needs of the client, including family therapy and self-help programs. The course concludes by focusing on the effects of a few of the more prevalent substances currently being abused, strategies for responding to them and harm reduction.
