Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug treatment center who recognize how challenging and difficult methadone detoxification 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 relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehabilitation center which has practical experience in dealing with this type of detox, and where the individual can receive further rehabilitation services to address all addiction issues.
