Well, if the public non-smoking agenda keeps rolling along like it has been, second-hand smoke will be a complaint of the past anyway.
But seriously, considering that marijuanna screws with the brain just as much as alcohol, I doubt many people will be smoking it in public even if it became legal, because there will probably be laws preventing them from driving while they’re high.
Oh, and don’t be hatin’ the substance, hate the idiots who use them irresponsibly. Recreational drugs are fine when used in moderation, and responsibly.
