Men and women who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eradicated from one's system, which is generally uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and present medical supervision for men and women who are just coming off of drugs. Detox services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can offer detoxification services, the client will have detoxification staff at their disposal around the clock to make certain that any difficulties are resolved as rapidly and safely as possible.
