Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug treatment program who realize how challenging and difficult methadone detoxification 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 ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under close supervision at a drug rehab program which has practical experience in handling this type of detox, and where the person can receive further treatment services to deal with all addiction issues.
