Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is usually uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and provide medical supervision for people who are just coming off of drugs. Detox services often include insuring the client is as relaxed 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 necessary to make the detoxification process as smooth and safe as possible. The 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 rehabilitation facility which can offer detox services, the person will have detoxification staff at their disposal around the clock to assure that any problems are handled as quickly and safely as possible.
