What is the difference between PG and VG?

PG, which stands for Propylene Glycol, is colorless, odorless liquid, which Is fairly thin and sweet. Propylene Glycol is the vehicle for flavor and also the ingredient in our liquids which provides that hit you feel in your throat.

VG, which stands for Vegetable Glycerine, is a much thicker and sweeter ingredient which causes the e-liquid to be smoother. It yields much more vapor than PG and also gives a much milder throat hit, which many vapers prefer.
