Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug treatment facility who understand how challenging and difficult methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under close supervision at a drug rehab facility which has experience in handling this type of detoxification, and where the person can receive further rehabilitation services to deal with all addiction issues.
