People who are physically dependent to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and supply medical supervision for people 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, delivering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The individual 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 supply detoxification services, the client will have detoxification staff at their disposal around the clock to assure that any difficulties are fixed as swiftly and safely as possible.
