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. Detox is basically the process of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and provide medical supervision for people who are just coming off of drugs. Detox services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is getting proper rest, and supplying supplements and medicine as wanted to make the detox process as easy and safe as possible. The person in detoxification 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 treatment facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to assure that any difficulties are handled as rapidly and safely as possible.
