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. Detoxification is basically the process of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the client 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 smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any difficulties are fixed as swiftly and safely as possible.
