Agreed, if banning one type of smoking, it'd be more straight to just ban them all. Or it becomes "taste policing": I/we/they don't like the smell of weed.

You don’t own an ICE or natural gas heater then right? Otherwise, “their pollution bad, my pollution good”

Correct, I don't own either. And even if I did, voluntary smoking cigarettes outside near people is not quite at the same level of necessity as heating your home or moving you from place to place, right?
