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. Detoxification is simply the procedure of the drug being eliminated from one's system, which is often uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can properly oversee and supply 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, delivering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as required to make the detoxification process as smooth and safe as possible. The 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 supply detox services, the individual will have detoxification staff at their disposal around the clock to guarantee that any difficulties are handled as quickly and safely as possible.
