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