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 procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is getting proper rest, and supplying 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 variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to make certain that any difficulties are handled as quickly and safely as possible.
