No....I'm vaping now, doing ok so far. But I'm smoking too. Last month when I realized I had a problem with the PG I did not vape for about 10 days to get all the PG out of my system and got better....now I am vaping the highbrow stuff, cheesecake torte is ok not having probs with it, except it is thick and hard on the clearo. The VV stuff is ok too, no headaches. Have you tried that VV Ecopure?
