Men and women who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services usually include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as necessary to make the detoxification process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to make sure that any complications are fixed as quickly and safely as possible.
