Are some people unaffected by alcohol?

Answer:

Alcohol affects anyone who drinks it. Some people have a high tolerance for alcohol which makes it seem that they are unaffected until they have had enough to exceed the tolerance level, at which point they usually become drunk quite rapidly.

A high tolerance for alcohol is a defining characteristic of alcohol addiction, by the way.
