Drug rehabilitation (often drug rehab or just rehab) is an umbrella 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.

Psychological dependency

Psychological dependency is addressed in many drug rehabilitation programs by attempting to teach the patient new methods of interacting in a drug-free environment. In particular, patients are generally encouraged or required not to associate with friends who still use the addictive substance. Twelve-step programs encourage addicts not only to stop using alcohol or other drugs, but to examine and change habits related to their addictions. Many programs emphasize that recovery is a permanent process without culmination. For legal drugs such as alcohol, complete abstention—rather than attempts at moderation, which may lead to relapse—is also emphasized ("One is too many, and a thousand is never enough.") Whether moderation is achievable by those with a history of abuse remains a controversial point but is generally considered unsustainable.

Types of treatment

Various types of programs offer help in drug rehabilitation, including: residential treatment (in-patient), out-patient, local support groups, extended care centers, and recovery or sober houses. Newer rehab centers offer age and gender specific programs.

In a survey of treatment providers from three separate institutions (the National Association of Alcoholism and Drug Abuse Counselors, Rational Recovery Systems and the Society of Psychologists in Addictive Behaviors) measuring the treatment provider's responses on the Spiritual Belief Scale (a scale measuring belief in the four spiritual characteristics AA identified by Ernest Kurtz); the scores were found to explain 41% of the variance in the treatment provider's responses on the Addiction Belief Scale (a scale measuring adherence to the disease model or the free-will model addiction).

Pharmacotherapies

Certain opioid medications such as methadone and more recently buprenorphine are widely used to treat addiction and dependence on other opioids such as heroin, morphine or oxycodone. Methadone and buprenorphine are maintenance therapies used with an intent of stabilizing an abnormal opioid system and used for long durations of time though both may be used to withdraw patients from narcotics over short term periods as well. Ibogaine is an experimental medication proposed to interrupt both physical dependence and psychological craving to a broad range or drugs including narcotics, stimulants, alcohol and nicotine. Some antidepressants also show use in moderating drug use, particularly to nicotine, and it has become common for researchers to re-examine already approved drugs for new uses in drug rehabilitation.

Counseling

Traditional addiction treatment is based primarily on counseling. However, recent discoveries have shown those suffering from addiction often have chemical imbalances that make the recovery process more difficult.

Criminal justice

Drug rehabilitation is sometimes part of the criminal justice system. 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. There have been lawsuits filed, and won, regarding the requirement of attending Alcoholics Anonymous and other twelve-step meetings as being inconsistent with the Establishment Clause of the First Amendment of the U. S. Constitution, mandating separation of church and state.
 

Diseased person model

Some psychotherapists question the validity of the "diseased person" model used within the drug rehabilitation environment. Instead, they state the individual person is entirely capable of rejecting previous behaviors. Further, they contend the use of the disease model of addiction simply perpetuates the addicts' feelings of worthlessness, powerlessness, and inevitably causes inner conflicts that could be resolved if the addict were to approach addiction as behavior that is no longer productive, the same as childhood tantrums.
