People who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is generally uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detox 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 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, supplying proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The particular person 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 rehabilitation facility which can present detoxification services, the individual will have detox staff at their disposal around the clock to make certain that any problems are handled as rapidly and safely as possible.
