People who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is typically uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detox services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring 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 detoxification will sometimes be encouraged to take part in some type 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 make sure that any difficulties are fixed as quickly and safely as possible.
