People who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is frequently uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can effectively oversee and present medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the individual 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 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 kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to make certain that any complications are handled as rapidly and safely as possible.
