You can make a mix of just vg and pg. but why? You’re concerned about the hazard of flavors, but not the possible hazards of vg, pg, coil and wick?
Normally, I’m not against people who have never smoked vaping - if it keeps them from ever smoking, I think that’s still a form of harm reduction. I wish it had been an option for me in the 70s.
But I have no idea why you want to vape at all. Seems like you just want to sit at the cool kid’s table and make clouds. Which, okay, you do you. But for Pete’s sake, educate yourself. If you really think flavors are the biggest or only danger, you do not have enough information to vape.
