Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab facility who realize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to ease 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 detoxification, and where the individual can receive additional recovery services to deal with all addiction issues.
