How did you not think of it once? Anyone who knows Marvel and Quesada would've picked up on the relevance to the ban the second you see the old man smoking in ASM.
I can't blame Quesada for putting smoking down, as I can't stand it either...but at the same time, I feel like he could address it a little differently. Informing everyone that smoking causes lung cancer through speech bubbles full of 'kaff kaff', with an accompanying info box seems a little bit odd to me. I already know that stuff, and I don't want patronising comics
