You wouldn't go to a cigar smoking club if you didn't want the smell of cigar smoke on you. No one is going to make you go to a marijuana smoking club so therefore you wouldn't be exposed to the smoke against your wishes. The law the article was discussing was specifically about allowing marijuana smoking clubs to exist... just like a hookah lounge or a tobacco club. I understand your concern about how smoke can et on you in ways that alcohol can't. But again this law is specifically about creating a space where people who wanted to smoke marijuana in a public (and hopefully contained space) and socialize could do so.
