Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who understand how challenging and difficult 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 typically revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab center which has experience in dealing with this type of detox, and where the person can receive additional recovery services to deal with all addiction issues.
