When I used to smoke analogs, I used to be a chronic nasal exhaler, until I was told that it was really bad for the nasal membrane along with our "smelling cells" or whatever you wanna call it. basically, over time it greatly reduced our ability to smell, and clogged the nose.
Now keep in mind these effects were not only caused by analog exhaling, but I was told that prolonged exposure to any type of unhealthy gasses, chemicals, or even dust had a similar effect.
So, while I do hate to be a party popper in this hilarious thread, I just wanted to point that out that. I think it should be added as another item on the list to thoroughly test with e-cigs.
