Individuals who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and supply medical supervision for people who are just coming off of drugs. Detox services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and supplying 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 detoxification facility or drug treatment facility which can provide detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any difficulties are resolved as swiftly and safely as possible.
