Does someone who hardly drinks get drunk faster than someone who drinks a lot?

Yes. Alcohol is a toxin and the body can only take a certain amount before a person blacks out or dies. The more a person drinks the more the body builds resistance to it. But drinking more often is not the only factor contributing to being intoxicated faster. Size is also a factor. So if you are bigger than your friend and you are both taking your first drink of your life, your friend is more likely to become intoxicated before you.
