People who are physically dependent to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being removed from one's system, which is often uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detoxification services, the individual will have detoxification staff at their disposal around the clock to ensure that any problems are handled as swiftly and safely as possible.
