Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug treatment facility who understand how challenging and difficult methadone detox can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users typically 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 should only be done under close supervision at a drug rehab program which has practical experience in dealing with this type of detox, and where the individual can receive further treatment services to deal with all addiction issues.
