Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab program who understand how challenging and difficult methadone detoxification can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and individuals 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 strict supervision at a drug rehabilitation program which has practical experience in handling this type of detoxification, and where the person can receive further rehabilitation services to deal with all addiction issues.
