Methadone detoxification is a course of action which should be undertaken by drug rehab specialists in an alcohol and drug rehab program that understands how serious and challenging methadone detoxification can be. Methadone detox is known to be significantly more severe in terms of symptoms and duration than even heroin detox, and persons often relapse back onto methadone to relieve symptoms of withdrawal or even worse turn to heroin or prescription pain relievers to relieve symptoms. This is why methadone detoxification should only be done under close supervision at a Greenland, New Hampshire drug detox facility which has experience in addressing this type of detox, and where the person may receive more extensive rehab methods to address all substance abuse concerns.
