Men and women 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 carry risks if not carried out in a setting which can provide appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and supply medical supervision for people who are just coming off of drugs. Detox services often include insuring the person 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 wanted to make the detoxification process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detox services, the individual will have detox staff at their disposal around the clock to assure that any difficulties are resolved as swiftly and safely as possible.
