While I agree, these laws aren’t being made because smokers keep accidentally smoking near others, it’s because a large number of smokers can’t be assed to keep their distance. The major place I notice smokers is when they are just meandering through a large crowd as if everyone around them is fine with the smoke.

The issue with smoking is the second hand smoke. It causes cancer, among many other health issues. Vape on the other hand doesn’t really have this same concern.

They aren’t banning smoking because of nicotine, they are banning it because it causes cancer.

Do you often spill drinks into the mouths of passerby’s?

The issue isn’t the substance, it’s the second hand smoke. Children are smart enough to know “this is a thing my parents do that I can’t” but no level of smart can keep the air they breath from containing smoke.
