People who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not performed in a setting which can supply 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 effectively oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is getting proper rest, and providing 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 kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detox services, the person will have detox staff at their disposal around the clock to guarantee that any problems are fixed as swiftly and safely as possible.
