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 basically the process of the drug being eliminated from one's system, which is frequently uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services frequently include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can present detox services, the person will have detox staff at their disposal around the clock to ensure that any issues are handled as swiftly and safely as possible.
