I really wish there were also laws about not doing it in public spaces. I don't care if people do it in their own spaces, but when the smell wafts out onto the sidewalk, it makes me nauseous.
At least it isn't hazardous like cigarette smoke. I really wish cigarettes were completely banned in public spaces. If you want to destroy your own lungs on your own property, fine. But I shouldn't have to breath it in.
Also, a bit of secondhand smoke outside isn't dangerous, it just smells bad.
