So I got a bottle of this stuff - CVS Pure Glycerin USP - CVS pharmacy thinking it was the same as flavorless VG I get from vendors - the 1 review it has is from someone using it for e-juice...however I just learned there IS a difference between vegetable glycerine and just plain glycerine, basically that gylcerine can contain petroleum products whereas VG is 100% plant-based. The bottle I got says 99.5% glycerine and I was told you can vape it, I'm just wondering if anyone else does this and do they notice a difference... I'm a little wary right now about inhaling this stuff lol.
