people eat PG all the time, it doesnt dissolve their organs. again with VG, PG is used everywhere - food, drink, health products, animal treatments and suppliments, etc.
im not trying to prove its water - To be factual, PG does contain a small amount of water however - from the spec sheets ive seen. water is present @ around 0.2%.
Everyone i know that vapes, mixes @ around 0-3% PG. So thats my expierience with "most people". I dont care if theres water in it or not. Vaporizing product in a VG/PG suspension is just a more efficient way of delivery than inhaling smoke and hundreds of other undisclosed chemicals, like with analog smoking.
