Men and women who are physically reliant to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and present medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the client 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 supplying supplements and medicine as needed 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 detoxification facility or drug rehabilitation facility which can offer detox services, the person will have detox staff at their disposal around the clock to make sure that any problems are fixed as swiftly and safely as possible.
