Disclaimer

Your actual BAC is dependent on many complex factors, including your emotional and physical condition and health, and what you've recently ingested (including food, water, medications and other drugs).

NOTE: The basic formula for estimating a person's blood/breath alcohol concentration comes from the National Highway Traffic Safety Administration.
