Drinking in the Harry Potter Films

I saw the sixth Harry Potter movie twice. Yeah, I'm a dork. I didn't notice how much drinking there was in the movie until one of the blogs I read directed me to this New York Times article. Context is everything. First of all, the books and movies are set in Britain, a culture which views drinking differently. Secondly, it's a fantasy, a world which doesn't exist. I tend to discount the argument that teens are more likely to smoke/drink if they watch movies with smoking and drinking because it's the same thing as questioning whether or not they can distinguish fantasy from reality.
