People who are physically reliant to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is frequently uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detox services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the particular person is getting proper rest, and providing 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 sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detox services, the client will have detoxification staff at their disposal around the clock to make sure that any issues are fixed as swiftly and safely as possible.
