People who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The particular 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 rehabilitation facility which can supply detoxification services, the individual will have detoxification staff at their disposal around the clock to assure that any difficulties are fixed as swiftly and safely as possible.
