People who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is frequently uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and provide medical supervision for people who are just coming off of drugs. Detox services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the individual is getting proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The individual 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 rehabilitation facility which can provide detoxification services, the individual will have detoxification staff at their disposal around the clock to guarantee that any difficulties are fixed as quickly and safely as possible.
