Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation program who realize how challenging and difficult 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 frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under strict supervision at a drug rehab center which has experience in handling this type of detoxification, and where the person can receive further rehabilitation services to deal with all addiction issues.
