Well because second hand smoke is so obvious and real and second hand vape... I mean... I'm not convinced it even exists. I see the vapor for about 2 seconds then it's gone. I can sniff as hard as I want, I'm not smelling anything.

But smoking? Woof. I could tell someone smoked 2 hours ago from 10 feet away. My fingers used to smell like ash 24/7. Even walking past someone 20 feet away, outside, in the wind, you can clearly smell cigarette smoke.

So I don't think it is the same.
