How do you ever know if it's enough? To me, I guess one definition that it's enough is does the individual know it's wrong? Does the individual know that it's illegal? Does the individual know that it could be harmful? My hunch is you could go into an elementary classroom, and those kids would know that (about underage drinking). I certainly know that at the senior high school, they would know that.
