People who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not conducted in a setting which can provide 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 supply medical supervision for men and women who are just coming off of drugs. Detoxification services usually include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can offer detoxification services, the individual will have detoxification staff at their disposal around the clock to guarantee that any difficulties are fixed as swiftly and safely as possible.
