People who are physically dependent to drugs or alcohol and want assistance will initially go through detox 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 carry risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as required to make the detox process as easy and safe as possible. The individual in detoxification 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 detoxification services, the client will have detox staff at their disposal around the clock to make certain that any problems are handled as quickly and safely as possible.
