People 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 eliminated from one's system, which is typically uncomfortable and may carry risks if not carried out in a setting which can supply appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services frequently include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as needed to make the detox process as smooth and safe as possible. The individual 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 rehab facility which can provide detoxification services, the person will have detox staff at their disposal around the clock to ensure that any complications are resolved as swiftly and safely as possible.
