Men and women who are physically dependent to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and present medical supervision for people who are just coming off of drugs. Detox services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can provide detox services, the client will have detoxification staff at their disposal around the clock to make certain that any difficulties are fixed as quickly and safely as possible.
