People who are physically dependent to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is often uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detoxification 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 person is getting proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detox services, the client will have detox staff at their disposal around the clock to make sure that any difficulties are fixed as quickly and safely as possible.
