Individuals who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is often uncomfortable and may carry risks if not carried out in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab 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, providing proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detoxification services, the person will have detoxification staff at their disposal around the clock to make certain that any complications are resolved as rapidly and safely as possible.
