People who are physically dependent to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not executed 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 properly oversee and provide medical supervision for people who are just coming off of drugs. Detox services frequently 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 getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some type 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 detoxification staff at their disposal around the clock to ensure that any difficulties are handled as rapidly and safely as possible.
