I'd be interested in helping too, from both a "fairly new vaper" and "asthmatic" perspective. I'm finding that while it must surely be better for my lungs than smoking, and not so much of that gross coughing up to do, VG is really not kind at all to asthmatic lungs, and I think that really needs to be addressed. I've been tapering back my PG usage, due to swollen feet/ankles, now vaping at about 67%PG/33%VG, and this morning, I woke, went to the bathroom, and almost before I could get back to the bed (where my inhaler was, beside the bed) I just literally almost could not breathe at all, and when I went to use the inhaler, it was hard just to get the inhaled medicine inside, on the first puff. It's got to be the VG, because when I was vaping 85% PG, I didn't have this problem at all.
Today, of course, I'm trying to go as lightly as I can possibly manage on vaping, because that really scared me, almost not being able to inhale my medicine, and I think I'm going to have to go back to a higher PG percentage.
