How to calculate your blood alcohol level?
When it comes to drinking, there’s no point looking to your friends, no matter how nice they are. Everyone responds differently to alcohol, depending on various physical and emotional factors. How quickly you drink, how much you weigh and how much muscle mass you have can also affect how you react. And, unfair as it may seem, alcohol affects women more quickly than men. In terms of impact, an average drink for a woman is equivalent to a drink and a half for a man. So it’s very important to know exactly what your tolerance is.
These charts can help you determine what your blood alcohol level is likely to be after drinking. Please remember that these figures are approximate only.
Subtract 15 mg of alcohol per hour from the time you take your first drink, since that’s the rate at which your body eliminates alcohol.
