Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation center 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 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 rehabilitation program which has practical experience in handling this type of detoxification, and where the individual can receive further rehabilitation services to deal with all addiction issues.
