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