Men and women who are physically reliant to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being eliminated from one's system, which is typically uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services generally include insuring the person 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 needed 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 rehabilitation facility which can provide detoxification services, the client will have detox staff at their disposal around the clock to guarantee that any problems are resolved as rapidly and safely as possible.
