Methadone detox is a course of action which should always be overseen with the assistance of drug detox experts in an alcohol and drug rehabilitation program that acknowledges how difficult and how much of a challenge methadone detox is. Methadone detox is known to be far more serious when considering symptoms and duration than even heroin detox, and individuals often go back to methadone to relieve symptoms or worse yet begin abusing heroin or prescription narcotics to relieve symptoms. For this reason methadone detoxification should only be undergone under close supervision at a Waterloo drug rehab which has experience in handling this type of detoxification, and where the person can partake in more rehab services to address all substance abuse concerns.
