People who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and present medical supervision for people who are just coming off of drugs. Detox services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as necessary to make the detoxification process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any difficulties are resolved as rapidly and safely as possible.
