People who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain 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 particular person 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 treatment facility which can present detox services, the person will have detoxification staff at their disposal around the clock to ensure that any issues are resolved as swiftly and safely as possible.
