People who are physically dependent to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and provide medical supervision for men and women who are just coming off of drugs. Detoxification services generally include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can present detox services, the person will have detoxification staff at their disposal around the clock to assure that any problems are handled as rapidly and safely as possible.
