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