which factors affect a person’s bac?

The question “What is my blood alcohol content?” speaks to the influence of many factors on the degree of alcohol impairment a person will experience.

Factors such as the following all come into play.

  • weight
  • body fat percentage
  • natural tolerance to alcohol
  • type and amount of food in the stomach

It’s also important to note that what really matters is not your BAC at any particular moment in time but what it was when you were drinking.

So if you’ve been drinking steadily for an hour then continue after checking your BAC and now have a slightly higher reading than at first, that can’t be used as proof that there has been any increased clearance.
