Methadone detox is a procedure which should be undertaken with the assistance of drug detox specialists in a drug rehab facility that understands how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be significantly more serious in terms of symptoms and duration than even heroin detox, and individuals often relapse back onto methadone to alleviate symptoms of withdrawal or even worse turn to heroin or medical opioids to relieve symptoms. This is why methadone detoxification should only be attempted under close supervision at a Greenville drug treatment facility that has experience in handling this form of detox, and where the individual can receive further rehabilitation services to address all substance abuse concerns.
