People who are physically dependent to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and supply medical supervision for persons who are just coming off of drugs. Detoxification services generally include insuring the individual is as relaxed 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 smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to assure that any issues are fixed as rapidly and safely as possible.
