Yes. "Too much" in this case should probably be considered "any". It's never good for you to get foreign particulate matter in your lungs. They act as irritants, even if you're not actually allergic to them (a distinct possibility).
I agree with every word above, but I also sure that your lungs would become blocked, and would lodge as tiny splinter particles which would cause breathing issues like a smoking person.
It could also cause Cancer if not treated for serious infections.
However my advice would be seek a doctor and get checked over.
