Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detoxification services are provided 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. Detox services generally include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detoxification services, the client will have detoxification staff at their disposal around the clock to assure that any difficulties are handled as quickly and safely as possible.
