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 process of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and present medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as wanted to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can present detoxification services, the client will have detoxification staff at their disposal around the clock to guarantee that any difficulties are resolved as rapidly and safely as possible.
