People who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is basically 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 detox facility or a drug rehabilitation facility which can correctly oversee and supply medical supervision for people who are just coming off of drugs. Detoxification services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as needed 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 kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detoxification services, the client will have detoxification staff at their disposal around the clock to make sure that any problems are fixed as swiftly and safely as possible.
