People who are physically reliant to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as wanted to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any issues are resolved as quickly and safely as possible.
