I guess that makes sense. I thought of the smell as nauseous but being dangerously unhealthy (than breathing the same concentration smoke from a fire, I'm assuming is the comparison) makes it involve different levels of health issues. I'd suppose they'd have to make the buyers sign waivers, huh, otherwise they have a number of civil class-action suits waiting--from which they lose anyway since a waiver would make the cutter much less attractive.
