Smoking IS Bad

They smoke for 30-40 years, then they show up, 'I had no idea it was bad for me!'
Come on. You're breathing in fire. What did you think you were doing, training for the circus?
Even if they didn't put a label on the pack, you would know it's bad for you, wouldn't you?
They don't need to put a warning label on a hammer for me to know if I smack myself in the face, it's gonna hurt.
