PG vs VG E Liquids

PG (propylene glycol) and VG (vegetable glyerine, or glycerol) are ingredients in e-liquid which create the vapor.

Both are widely used in a variety of products for human consumption. PG is associated with a stronger “throat hit” but with less visible vapor, whereas VG has a sweetish taste and produces a much more visible vapor. Some vapers find PG irritates their throat and lungs and choose to use VG based e-liquids instead. Some e-liquids contain a blend of both ingredients to balance out the characteristics of each.
