People who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and present medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as easy and safe as possible. The particular person in detoxification 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 guarantee that any complications are handled as rapidly and safely as possible.
