BASIC DRUG RAHABILITATIONDrug rehabilitation (often drug rehab or just rehab) is an umbrella term for the processes of medical and/or psychotherapeutic treatment, for dependency on psychoactive substancesalcohol, 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.
Drug rehabilitation tends to address a stated two fold nature of drug dependency: physical and psychological dependency. Physical dependency involves a detoxification process to cope with withdrawal symptoms from regular use of a drug. With regular use of many drugs, legal or otherwise, the brain gradually adapts to the presence of the drug so the desired effect is minimal. Apparently normal functioning of the user may be observed, despite being under the influence of the drug. This is how physical tolerance develops to drugs such as heroin, amphetamines, cocaine, nicotine or alcohol. It also explains why more of the drug is needed to get the same effect with regular use. The abrupt cessation of taking a drug can lead to withdrawal symptoms where the body may take weeks or months (depending on the drug involved) to return to normal.
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.
