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 process of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services frequently include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering 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 particular person in detoxification 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 rehab facility which can supply detoxification services, the individual will have detoxification staff at their disposal around the clock to ensure that any problems are fixed as rapidly and safely as possible.
