"In medical terminology, addiction is a state in which the body relies on a substance for normal functioning and develops physical dependence. It is a term that is specifically applied to drug addiction. When the drug or substance on which someone is dependent is suddenly removed, it will cause withdrawal, a characteristic set of signs and symptoms. Addiction is generally associated with increased drug tolerance. In physiological terms, addiction is not necessarily associated with substance abuse since this form of addiction can result from using medication as prescribed by a doctor."
