People who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically 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 supply appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and provide medical supervision for men and women who are just coming off of drugs. Detox services frequently include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as required to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to ensure that any difficulties are fixed as swiftly and safely as possible.
