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 detoxification can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals frequently 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 must only be done under strict supervision at a drug rehab facility which has practical experience in handling this type of detoxification, and where the person can receive further recovery services to deal with all addiction issues.
