Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehab program who realize how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more serious 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 alleviate symptoms. This is why methadone detox should only be done under strict supervision at a drug rehabilitation program which has practical experience in handling this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
