All the second hand smoke in this thread was starting to make me cough and make my clothes smell funny. Wait...that was the torches, pitchforks, and burning crosses......crap...
One does have to wonder if "second hand smoke" results were any different if it was ^that^ smoke instead of tobacco smoke. Or smoke from the "hole in the roof" chimneys... Oh wait, back then we didn't live long enough to die of cancer, so that makes it OK then.
