Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehab center who realize 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 users typically 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 must only be done under close supervision at a drug treatment center which has experience in handling this type of detox, and where the person can receive further treatment services to deal with all addiction issues.
