People who are physically dependent to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is often uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and supply medical supervision for people who are just coming off of drugs. Detox services typically 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 individual is receiving proper rest, and providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detox services, the individual will have detox staff at their disposal around the clock to make sure that any problems are handled as rapidly and safely as possible.
