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. Detoxification is basically the procedure of the drug being eradicated from one's system, which is frequently uncomfortable and may carry risks if not conducted 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 adequately oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can present detox services, the client will have detoxification staff at their disposal around the clock to make sure that any problems are resolved as quickly and safely as possible.
