Drug rehabilitation is the process of medical or psychotherapeutic treatment for dependency on psychoactive substances such as alcohol, prescription drugs, and street drugs such as cannabis, cocaine, heroin or amphetamines. The general intent is to enable the patient to confront substance dependence, if present, and cease substance abuse to avoid the psychological, legal, financial, social, and physical consequences that can be caused, especially by extreme abuse.
Treatment includes medication for depression or other disorders, counseling by experts and sharing of experience with other addicts.
