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 eliminated from one's system, which is usually uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can appropriately oversee and present medical supervision for people who are just coming off of drugs. Detox services usually include insuring the person is as relaxed 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 needed to make the detox process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detoxification services, the client will have detox staff at their disposal around the clock to make sure that any problems are handled as quickly and safely as possible.
