The broad term "drug rehabilitation", or "drug rehab", is a collection of treatments and procedures (pharmaceutical, psychotherapeutic, medical, etc.) to help an individual get rid of his or her drug dependency, including psychological and physical types of dependency on various psychoactive agents, such as "street drugs" (amphetamine, crystal meth, heroin, cocaine, etc.), alcohol, prescription drugs, and so on.
Various measures of drug rehabilitation are intended to enable the drug user to stop abusing drugs and, therefore, to avoid the numerous negative consequences and implications of substance abuse - legal, physical, physiological, social, and financial.
