Hello and welcome to the forum
@Jozeph87. Glad to have you here!
PG = Propylene Glycol - the "flavor carrier" of
e-liquid. A secondary source of "throat hit", but not as strong as the nicotine concentration. Some people have a sensitivity or even an allergy to PG. It's very thin.
VG = Vegetable Glycerin - the "vapor maker" of
e-liquid. Used as a sweeter in many food sources, and also as a skin emollient. It's very thick. Often labeled just "Glycerine"
PG and VG are often used together in different ratios in
e-liquid. For example, a 50/50 PG/VG ratio. Some juice vendors offer a range of different ratios as far as PG/VG.
