Men and women who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The particular person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detox services, the person will have detox staff at their disposal around the clock to make certain that any difficulties are resolved as swiftly and safely as possible.
