Addiction Medicine (ADM) is a recognized physician subspecialty of the American Board of Medical Specialties. [1]
Addiction is a treatable, chronic medical disease involving complex interactions among brain circuits, genetics, the environment, and an individual’s life experiences. People with addiction use substances or engage in behaviors that become compulsive and often continue despite harmful consequences. [2]
Dependence or physical dependence is used in the psychopharmacological context in a narrower sense, referring solely to the development of withdrawal symptoms on cessation of drug use. [3]
