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