Methadone detoxification is a process which should always be undertaken by drug detox experts in a drug rehabilitation facility that understands how difficult and how much of a challenge methadone detox is. Methadone detoxification is very often far more severe when considering symptoms of withdrawal and duration than even heroin detoxification, and persons often go back to methadone to ease symptoms of withdrawal or worse yet begin abusing heroin or medical pain relievers to ease symptoms. For this reason methadone detox should only be undergone under close supervision at a Smithfield, RI. drug detox facility which has experience in handling this form of detox, and where the individual who is detoxing may receive more extensive treatment services to handle all addiction issues.
