Individuals 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 basically 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 needed. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and supply medical supervision for people who are just coming off of drugs. Detoxification services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as wanted to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can present detox services, the individual will have detoxification staff at their disposal around the clock to assure that any difficulties are handled as quickly and safely as possible.
