Methadone detox is a procedure which should always be overseen by drug detox specialists in an alcohol and drug rehabilitation program that understands how serious and how much of a challenge methadone detox can be. Methadone detox is very often far more serious in terms of symptoms and duration than even heroin detox, and individuals can very easily relapse back onto methadone to alleviate symptoms or even worse begin abusing heroin or medical opioids to ease symptoms. This is why methadone detoxification should only be done under close supervision at a Simi Valley drug rehab that has expertise in addressing this type of detoxification, and where the individual can partake in further rehab services to address all substance abuse concerns.
