I have been vaping about a month now. Before I was a very light smoker maybe one or two a day and sometimes none. I've been using a 6mg nicotine. After a week a switched to max vg because I was experiencing skin breakouts. All seemed better but now I'm coughing and wheezing a lot. I even busted out an old inhaler from my "heavy" smoking days. Could this be an allergic reaction to pg? I did read somewhere that max VG (which I use) still has some pg. Should I try 100% VG? I haven't had breathing problems like this since I smoked a pack of reds a day years ago. Any advice would be appreciated.
