People who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is frequently 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 detoxification facility or a drug rehab facility which can adequately oversee and supply medical supervision for people who are just coming off of drugs. Detox services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy 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 detox facility or drug treatment facility which can present detox services, the individual will have detox staff at their disposal around the clock to assure that any difficulties are handled as rapidly and safely as possible.
