People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the procedure 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 provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as wanted 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 kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can present detox services, the person will have detoxification staff at their disposal around the clock to make certain that any issues are handled as swiftly and safely as possible.
