Blood Alcohol Charts

Drinking can be a lot of fun. But the most important thing to  remember is you have to KNOW YOUR LIMIT. Below I’ve provided Blood Alcohol Charts for both men and women to help you understand how alcohol effects your mind and body. These numbers are an approximation and will vary based on rate of consumption and food intake.
