Bupe Snorting Suboxone--Damaging to Lungs?

OK, so I now know that talc is damaging to the lungs (which I guess is a filler in many pills), but does the same hold true for buprenorphine? I looked up the ingredients, and the only thing that jumped out at me as a potential hazard was magnesium stearate, but I have no idea if this carries the same risk as talc or not.

Taking smaller lines will prevent "lines" from getting into your lungs. I have never had this problem since I broke up my drugs into smaller lines, and didnt inhale too hard.
