People who are physically reliant to drugs or alcohol and want assistance will initially 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 typically uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The particular person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to assure that any issues are resolved as rapidly and safely as possible.
