Smoking causes everything

From American Lung Association

As far as we know the tradition of smoking tobacco dates from around 8000 years ago and it has never been so seriously criticized as it has been in the previous few decades.

I remember, when I was a child, a friend of my father who was told that smoking is the habit of “poor, stupid and black” and he commented that he is neither poor or black and briefly stated, “I must be stupid then!”
