Individuals who are physically dependent to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated 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 necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services typically include insuring the client is as comfortable 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 needed to make the detox process as smooth and safe as possible. The individual 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 present detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any complications are fixed as quickly and safely as possible.
