Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehab center who understand how difficult and challenging 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 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 detox should only be done under close supervision at a drug rehabilitation center which has practical experience in handling this type of detoxification, and where the person can receive additional treatment services to handle all addiction issues.
