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 process of the drug being removed from one's system, which is frequently uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and provide 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 individual is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can supply detoxification services, the individual will have detoxification staff at their disposal around the clock to ensure that any problems are handled as rapidly and safely as possible.
