I don't think alot of stuff would go into your lungs from snorting, since it would first hit your wet mucous membranes in both your nose and throat before going into your lungs
There was a similar thread to this not to long ago where another intelligent, informed BLer gave some statistics about only 12% of the powder actually sticking to mucus membranes and the rest going into the lungs. I can't find it now though, but it was pretty scary.
