People who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is frequently uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detox 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. Detoxification services frequently include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as wanted to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to make certain that any difficulties are resolved as rapidly and safely as possible.
