multiple substances from one or more of those groups, each a dependency of the same patient.
Frequent (but in no case universal) elements of such rehab are:
Twelve-step programs,
the doctrine that recovery is a permanent process without a culmination, whence the adjective "recovering" before "addict", "alcoholic", etc.
the doctrine that addicts' attempts at moderation rather than complete abstention inevitably produces relapse (with the slogan "I don't want a drink, I want too many drinks.")
In any case, the intent is to enable the patient to cease their previous level of abuse, for the sake of avoiding its legal, social, and physical consequences, especially in extreme abuse; the controversies over seeking moderation or abstinence are almost entirely factual diagreements about whether moderation is achievable by persons with a history of abuse, not about the morality or harm of moderate use by those who practice it with apparent success.
Substanceabuse refers to the overindulgence in and dependence on a stimulant, depressant, or other chemical substance, leading to effects that are detrimental to the individual's physical or mental health, or the welfare of others.
There are on-going debates as to the exact distinctions between substanceabuse and substance dependence, but current practice standard distinguishes between the two by defining substance dependence in terms of physiological and behavioral symptoms of substance use, and substanceabuse in terms of the social consequences of substance use.
Substanceabuse is sometimes used as a synonym for drug abuse, drug addiction, and chemical dependency, but actually refers to the use of substances in a manner outside sociocultural conventions.
Drug rehabilitation is an umbrella term for process 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 obvious intent is to enable the patient to cease their previous level of abuse, for the sake of avoiding its legal, social, and physical consequences, especially in extreme abuse.
People convicted of minor drug offenses may be sentenced to rehabilitation instead of prison, and those convicted of driving while intoxicated are sometimes required to attend Alcoholics Anonymous meetings.
