People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The particular person in detoxification 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 rehab facility which can supply detox services, the person will have detoxification staff at their disposal around the clock to ensure that any issues are fixed as rapidly and safely as possible.
