Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being eradicated 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. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and present medical supervision for persons who are just coming off of drugs. Detox services frequently include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy 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 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 resolved as swiftly and safely as possible.
