I don't know what you think the studies on this say, but I assure you none of them support the position that it's dangerous to walk past someone smoking. Again

I don't know what you think the studies on this say, but I assure you none of them support the position that it's dangerous to walk past someone smoking. Again, it's only because there's a deliberate hysteria around this issue that my claim seems even remotely controversial to you. And, yes, even the CDC is capable of hyperbole: Secondhand smoke harms children and adults, and the only way to fully protect nonsmokers is to eliminate smoking in all homes, worksites, and public places.1,2,3 Yes, I mean, that's trivially true. Eliminating all smoke in the world is the only way to ever truly be safe <cue scary music>.
