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 basically the process of the drug being eradicated from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as easy and safe as possible. The particular person in detox 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 detox services, the client will have detox staff at their disposal around the clock to ensure that any problems are fixed as quickly and safely as possible.
