So I stopped smoking last night and have been vaping since then. When I ordered my vape gear, I also got some liquid, and because I had never tried nicotine salt liquid, I thought I'd give it a go. But when I vape it, it really makes me cough. I never had that problem with normal nicotine. Is that because it is 50% VG / 50% PG or is nicotine salts the reason? A couple of years ago, I used to vape high VG liquid with normal nicotine and never had this problem before.
