People who are physically dependent to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is frequently uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detoxification services, the individual will have detoxification staff at their disposal around the clock to assure that any issues are handled as quickly and safely as possible.
