People who are physically dependent to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is often uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can present detoxification services, the client will have detoxification staff at their disposal around the clock to make sure that any complications are handled as quickly and safely as possible.
