Individuals 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 simply the process of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The particular person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to make certain that any issues are handled as rapidly and safely as possible.
