I haven't experienced anything like a burn, but have heard that quite a bit. Some people are sensitive to some suppliers PG, Flavorings. possibly even the brand of nicotene. Are you normally sensitive to various types of, chemicals, After shave, perfume,
or even some brands of face and laundry soaps? Does this happen with a few sellers juice or is it isolated to a particular brand juice? I'd be curious on your anwers. I have a friend who gave up on vaping because pg made him ill. He didn't want to use VG
juices because he said he didn't get enough flavor or Throat hit. I can see this as I don't like all VG for the same reasons. I will say that Boba's bounty had a decent TH for straight VG, but most brands I find lacking in VG alone.
