People who are physically reliant 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 eradicated from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can offer 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 appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The person in detoxification 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 rehab facility which can provide detox services, the individual will have detoxification staff at their disposal around the clock to guarantee that any issues are handled as rapidly and safely as possible.
