People who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services frequently include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as needed to make the detox process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to make sure that any issues are fixed as rapidly and safely as possible.
