People who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the client 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 needed to make the detox process as easy and safe as possible. The particular person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can offer detox services, the person will have detox staff at their disposal around the clock to make certain that any issues are resolved as quickly and safely as possible.
