Individuals 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 basically the process of the drug being removed from one's system, which is frequently uncomfortable and may hold 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 detox facility or a drug treatment facility which can correctly oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring 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 particular 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 treatment facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to assure that any difficulties are resolved as quickly and safely as possible.
