Drug rehabilitation (often
drug rehab or just
rehab) is a term for the processes of medical and/or psychotherapeutic treatment, for dependency on
psychoactive substances such as
alcohol,
prescription drugs, and so-called
street drugs such as
cocaine,
heroin or
amphetamines. The general intent is to enable the patient to cease substance abuse, in order to avoid the psychological, legal, financial, social, and physical consequences that can be caused, especially by extreme abuse.
