I'm allergic to dusts, and many spray can propellants (and the spray-contents) make me cough. The Krylon paint I use for the camo does 'cause it has fine particles to make the finish matt. Been making sure ever since my allergy diagnosis to wear a mask when making dist (especially with my dremel) because my lungs are buggered enough as it is (had pneumonia twice, and sepsis twice after that)

I'd say leave the smokers for large areas (like gymn displays) or open areas, that way you don't get complaints from the spectators. Wiping down the tank afterward with a damp cloth might be good too, to get any residue off the area surrounding the emitters.
