People who are physically dependent to drugs or alcohol and want help will initially 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 typically uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and supply medical supervision for persons who are just coming off of drugs. Detoxification services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The particular person 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 treatment facility which can supply detox services, the person will have detox staff at their disposal around the clock to ensure that any problems are handled as quickly and safely as possible.
