Have you ever met someone who didn't know cigarettes are addictive and dangerous?
They print it all right there on the box, and at the bottom of every advertisement (are there even still cigarette ads? I never see them around), and you can't complete school without being told over and over how dangerous they are. I think these days the cigarette companies don't even need to do anything. Cigs are there, if you want them they're easy to find, everyone knows what they do, some will still choose to smoke them.
Yes, my grandfather. Back then, the dangers of smoking were not well known by the public. In fact, the tobacco industry pushed bogus research to attempt to throw the conclusion that smoking causes cancer into doubt. Once it was apparent that smoking was harmful, my grandfather quit smoking cold turkey.
It was too late. He spent more than a decade coughing up his lungs only to finally succumb to cancer, weakened by the steroids keeping him alive to the point where he broke his back picking up a gallon of milk.
