An addiction medicine physician is a medical professional who provides treatment within the bio-psycho-social framework for individuals with addiction, for people with substance-related health conditions, for individuals who embrace unhealthy substance use and for those whose health is affected by another’s substance use or addiction. An addiction medicine physician is clinically trained to address substance use and addiction in ambulances, long-term care facilities, psychiatric settings, and residential facilities. Addiction medicine physicians also provide treatment to those who have co-occurring general medical and psychiatric conditions. An addiction medicine physician is a key member of the medical team and provides consultation services for other physicians. While some addiction medicine physicians limit their practice to patients with addiction, other concentrate on patients within their initial medical specialty.
