Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab facility who understand how difficult and challenging 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 must only be done under close supervision at a drug rehab program which has experience in dealing with this type of detoxification, and where the individual can receive further rehabilitation services to address all addiction issues.
