People who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is often uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can effectively oversee and supply medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the particular person is getting proper rest, and providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can present detoxification services, the individual will have detox staff at their disposal around the clock to ensure that any difficulties are handled as swiftly and safely as possible.
