Blood Alcohol Concentration (BAC) is the amount of alcohol present in the blood. It is calculated by determining how many milligrams of alcohol are present in 100 milliliters of blood.
We created a card to help you estimate your BAC. These cards can help you monitor various factors that affect your BAC such as sex, weight and hours spent drinking. All drinks are not created equal, so use these cards to learn about drink equivalents, and remember to “keep it in the green!”
The green levels on the card are the areas where you’re least likely to encounter the negative and potentially dangerous effects of alcohol consumption.
While it’s certainly your best bet to avoid drinking all together, and it’s downright illegal to drink if you’re under the age of 21, those that do choose to drink should use the card to ensure that they make the safest and most responsible decisions possible.
