Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehabilitation facility who realize 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 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 should only be done under strict supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the individual can receive further rehabilitation services to address all addiction issues.
