I'm sure this has been discussed somewhere before but it might be worth revisiting 
VG or PG - which do you prefer and why?
VG or PG - which do you prefer and why?

VG. After switching to all VG its hard to imagine vaping that foul PG radiator fluid. And then there are the side effects ...
Very informative, thanks guys...and galsSo "health wise" other than allergies. There is no real difference to your lungs?
Some VG is animal fat based.
all vg almost has a fishy taste to me
my fav mix is 70/30
or what mlv uses i think ians is 50/50 but i never find it too thick
I believe you're referring to standard "Glycerin" or "Glycol" - both of which can be made from animal and/or plant bases - inlcuding mixes of both. You can also purchase "Animal Glycerin" - which is made of animal fats and bone tallow.
Vegetable Glycerin USP is derived entirely from vegetable sources. The bottle needs to be marked specifically - or it could be a mix or animal-fat based.
Generic Glycerin and Glycol mixes are readily available in stores and pharmacies including walmart.
VG USP can be a bit more difficult to find. Most health food stores carry it. Also - some pharmacies.
