weedtime

I'm not in the US, but my city smelled like weed before it was legal and it smells like weed now too lol.

Like frosty said, some places make rules that you can't smoke in public. But even without that, people are generally discrete. I (dry flower) vape in public, generally when out for walks. I imagine it's the same etiquette that is expected of cigarette smokers: don't blow smoke in people's faces, don't smoke in crowded areas like bus shelters (not allowed anyways), don't litter, etc.
