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