People who are physically dependent to drugs or alcohol and want help will 1st go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and provide medical supervision for individuals 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 ensuring the individual is receiving proper rest, and providing supplements and medicine as necessary to make the detoxification process as smooth and safe as possible. The 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 supply detox services, the individual will have detoxification staff at their disposal around the clock to make certain that any difficulties are resolved as quickly and safely as possible.
