Methadone detoxification is a procedure which should be undertaken with the assistance of drug rehab experts in an alcohol and drug rehab center that acknowledges how serious and how much of a challenge methadone detox can be. Methadone detoxification is known as being far more serious when considering symptoms of withdrawal and length of time detoxing than even heroin detox, and individuals sometimes relapse back onto methadone to relieve symptoms or even worse begin abusing heroin or medical pain relievers to relieve symptoms. This is why methadone detoxification should only be done under with the help of treatment professionals at a Haverhill, New Hampshire drug rehab which has experience in addressing this form of detox, and where the individual can receive further rehabilitation services to handle all substance abuse problems.
