Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation facility 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 users often revert back to methadone to alleviate 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 rehab center which has practical experience in dealing with this type of detox, and where the person can receive further treatment services to address all addiction issues.
