Ok... This is just nonsense. A passive smoker is a non-smoker. Can they attribute these numbers to actual contact with a smoker? Or were these people hit by a bus when they were fleeing the guy that just lit up?
BWAHAHAHA
Even if that were the case, it would still be a death attributed to exposure to someone else's smoke. That is about the only way I can figure they come up with some of this stuff.
