Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can appropriately oversee and present medical supervision for people who are just coming off of drugs. Detox services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as necessary to make the detox process as easy 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 detox facility or drug rehab facility which can provide detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any issues are resolved as quickly and safely as possible.
