Men and women who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services often include insuring the client 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 needed to make the detoxification process as smooth and safe as possible. The individual 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 rehabilitation facility which can present detox services, the person will have detox staff at their disposal around the clock to make sure that any problems are fixed as swiftly and safely as possible.
