Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug treatment program who understand 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 often 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 should only be done under close supervision at a drug rehabilitation facility which has experience in dealing with this type of detoxification, and where the person can receive further treatment services to handle all addiction issues.
