People who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is often uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can effectively oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The individual in detox 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 rehab facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to ensure that any complications are fixed as swiftly and safely as possible.
