Question

Can ethnicity affect ur BAC?

Answer 1

Yes, it can. Not tremendously, but I know that many Asians have an enzyme deficiency that makes it difficult for some to break down alcohol.

Answer 2

Have you ever met an Irishman?

Answer 3

As has already been said, Asians tend to be able to process alcohol less efficiently.  

Ethnicity's affect on drinking habits and drinking mortality has been studied a bit, and I found the cited website very interesting.
