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