People who are physically dependent to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services frequently include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the particular person is receiving proper rest, and supplying supplements and medicine as necessary to make the detox 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 treatment facility which can present detox services, the person will have detoxification staff at their disposal around the clock to ensure that any problems are resolved as rapidly and safely as possible.
