Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is often uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and provide medical supervision for persons who are just coming off of drugs. Detox services frequently include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as required to make the detox process as smooth 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 detox facility or drug rehab facility which can provide detox services, the individual will have detoxification staff at their disposal around the clock to make certain that any issues are fixed as quickly and safely as possible.
