People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detox services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as required to make the detox process as smooth and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detox services, the individual will have detoxification staff at their disposal around the clock to assure that any difficulties are fixed as quickly and safely as possible.
