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. Detox is basically the procedure of the drug being eliminated from one's system, which is often uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and supply medical supervision for people who are just coming off of drugs. Detoxification services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any complications are fixed as quickly and safely as possible.
