People who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eliminated from one's system, which is typically uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and supply 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 making certain the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any problems are fixed as swiftly and safely as possible.
