Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehab center who recognize 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 ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under strict supervision at a drug treatment program which has experience in dealing with this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
