Men and women who are physically reliant to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is usually 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 rehabilitation facility which can correctly oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can provide detox services, the client will have detoxification staff at their disposal around the clock to make sure that any difficulties are resolved as rapidly and safely as possible.
