Definitely possible IMO! Seems like it would be surprising tho - consider the disparities in volume. I think the boring answer is that breathing smoke is dangerous, despite the occult and ambience benefits of a hearth ;( it forms minute bits of plastic that are tinier than 5 millimeters long. Their size means they end up everywhere, even in our blood, where they range in size between 700 nanometers and 5,000 nanometers.
