Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab program who realize how difficult and challenging methadone detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification should only be done under strict supervision at a drug rehab program which has practical experience in dealing with this type of detox, and where the person can receive additional treatment services to handle all addiction issues.
