Methadone detoxification is a process which should always be overseen with the assistance of drug detox experts in an alcohol and drug rehab center that understands how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more severe in terms of symptoms of withdrawal and length of time detoxing than even heroin detox, and persons can very easily go back to methadone to relieve symptoms or worse yet turn to heroin or medical pain relievers to relieve symptoms. This is why methadone detox should only be done under close supervision at a Hensley drug detox facility which has experience in addressing this type of detox, and where the person may receive further rehab methods to handle all addiction problems.
