People who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and supply medical supervision for persons 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, offering proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy 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 detoxification facility or drug treatment facility which can present detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any problems are handled as quickly and safely as possible.
