Blood Alcohol Concentration

The following charts show some approximate Blood Alcohol Concentration (BAC) levels based on sex, weight, and number of drinks containing alcohol. For each hour that a person drinks (including the first one), one should subtract 0.015 from the BAC. While these charts may give you a general guideline of where your BAC might be, do not use these charts to influence your decisions in regards to driving. Individual factors including, but not limited to, genetics, food consumption, and use of other drugs, may lead to a higher BAC.
