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