The difference is that you have a choice to be in an environment filled with cigarette smoke, and don’t often have a choice to be in a pollen filled environment.
I asked Sender ... "how do you do in "fresh" air filled with pollen?"
The point is, though you avoid areas you knowingly are allergic to, ie: those dreaded smokey bars you must inhabit the rest of the planet.
Now, if you have a genetic condition that precludes you from breathing "fresh" air, obviously you are in deep doo doo.
Of course, as the imurities found in "fresh" air are, no doubt, the fault of humans we should demand that the earth's air be filtered.
Perhaps the UN could do that, when they get the chance.
I have chronic asthma.. and the fire works have sent me to the ER.. but alas, I just dont go out doors any more on the 4th of july evening....you would think this young lady had to know that smoke bothered her asthma..
