My cousin died from lung cancer caused by secondhand smoke. Her smoker husband is still alive in his 60's.

You could well be right.

On the other hand, what do we call the "products of combustion" in other circumstances? A: Air pollution. Science backs up the fact that sludge in the air irritates our lungs.

I'm not sure how I got into this :-). I certainly have no interest in regulating other people's smoking!
