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 often uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The particular person in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detox services, the individual will have detox staff at their disposal around the clock to assure that any problems are resolved as rapidly and safely as possible.
