I usually vape 70pg/30vg with no problem. I bought a 100% VG flavor the other day because that's all that was offered in that much talked about flavor. I loved the flavor btw. The first time I vaped it I had some chest tightness and had to use my asthma inhaler, but I thought that it was everyday allergies acting up and didn't think anything else about it. I didn't vape it for a few days cause I had trouble with my tank and carto but that's beside the point. When I vaped it again, the same thing happened almost immediately. I could literally fell my chest tighten up. No other symptoms, just cough and chest tightness and wheezing. Using the inhaler makes it go away. I tried another 100% VG flavor I bought later that day and had the same result. I went back to my 70pg/30vg mix and all was well. Today I tried again, just cause I wanted to see if it was a fluke the first three times..immediately had to reach for the inhaler. Needless to say, I'm no longer going to vape those flavors, which is a shame cause I have a 30ml bottle Boba's now that I can't use, and I really like it too. I'd much rather breathe though.
Anyway, has anyone ever heard of this happening with a 100% VG? I thought a PG allergy would be more likely but I seem fine with pg.
