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 detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals often 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 strict supervision at a drug rehabilitation program which has practical experience in handling this type of detoxification, and where the person can receive additional rehabilitation services to deal with all addiction issues.
