Individuals who are physically reliant to drugs or alcohol and want help will initially 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 generally uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can effectively oversee and present medical supervision for persons 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 making certain the person is getting proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The 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 rehab facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to make certain that any complications are resolved as swiftly and safely as possible.
