I've not seen any..
Here's the problem though, you'd have to have had an xray taken just prior to beginning to vape.. like a before and after in order to see what the differences are.
That's why studies pick people and then follow them through the course of before and after.
Therefore, the long time vapers who have been
vaping since the beginning are less likely to be picked for any new studies of long term effects.
You can pat yourself on the back though. Because
vaping didn't kill you and you were willing to go first, others decided
vaping was safe enough for them to try too..
You ma'am are responsible for giving people the confidence to save their own life. We watched you not die and took note. Thank you for being the most awesome guinea pig ever!
