Individuals who are physically dependent to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and present medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as necessary 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 sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can offer detoxification services, the person will have detoxification staff at their disposal around the clock to make certain that any problems are resolved as rapidly and safely as possible.
