This is an interesting topic for me. I realized I was born with congenital lung defects (a boatload of blebs) 6 years ago when my lung spontaneously collapsed (while sitting at my desk at home, blogging on the computer, for cripes sake.) And yet I tested out as negative for both emphysema and COPD... Bottom-line, I have weak out-pouches/bubbles on the surface of my lungs, which with phlegm/mucus in the lung put stress on the weak spots and they go POP.
So, smoking is a huge no-no for me. I have tried gum, patches, lozenges and have been thinking of hypnosis. But I've been hearing so many success stories about E-cigs that I've decided to give it a go. And am STILL trying to find the best set up for me to start with...
Anyway, thanks for bring up this subject. I had not thought about any tie in between vaping and lung congestion. But will now be looking into it a bit more. It's nice to know that hospitals use PG in treatments..
Side question, I believe I've acquired a moderate allergic reaction to petroleum byproducts, is there anything with vaping that I should avoid?
