My Niece is somewhat allergic to PG. She really wants to vape, not sure yet if she's going to have to go 100% VG or maybe just a high vg/pg blend. My husband got a rash from using high pg liquids too but he's able to use 50/50 ok without a rash. Question to VG users, what kind of pv do you find works with VG liquids? I know they're thicker and what I use (Ego Mega Dual Coil Cartomizer's) don't work at all with 100% VG. Any advice greatly appreciated!
