If you read any old literature, even as far back as the 1800's, you get this feeling. No one ever outright says "this will kill you," but it was certainly regarded as a poor health choice.

The one thing that bugs me about this was, as a kid in a health class, I was shown a video of a little girl and her grandma. The girl asked the grandma "Why do you smoke grandma?" The old lady responded "Because when I was your age, nobody knew that smoking was bad for you."

The bullcrap we were fed as kids is incredible.
