In real live plasmas give off some odor. The closest to a reference I find is this. But one can easily check for himself. It's mostly ozone what one smells (smell of thunderstorms).
So I was wondering as lightsabers are kind of plasma and we sometimes see even flashes between blades - do lightsabers have a peculiar odor?
