Men and women who are physically dependent 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 eliminated from one's system, which is often uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and provide medical supervision for men and women who are just coming off of drugs. Detox services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The individual in detox 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 offer detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any problems are handled as rapidly and safely as possible.
