Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab center 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 individuals frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehabilitation center which has practical experience in dealing with this type of detoxification, and where the person can receive further treatment services to deal with all addiction issues.
