Methadone detoxification is a process which should always be overseen by drug rehab professionals in an alcohol and drug rehab facility that recognizes how serious and challenging methadone detox can be. Methadone detox is known as being far more severe when considering symptoms and length of time detoxing than even heroin detox, and persons sometimes relapse back onto methadone to relieve symptoms or even worse turn to heroin or medical pain relievers to relieve symptoms. For this reason methadone detox should only be done under close supervision at a Greenwood drug treatment facility that has experience in handling this type of detox, and where the individual may partake in more extensive treatment methods to handle all addiction issues.
