Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehabilitation facility who realize 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 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 should only be done under close supervision at a drug rehab program which has experience in handling this type of detox, and where the person can receive additional treatment services to address all addiction issues.
