Vegetable Glycerin or “VG” is a thicker liquid. It is the base of all e-liquid formulations. VG also produces a lot of vapour on exhale. Higher VG content juices tend to be a smoother hit, depending on nicotine level.

Propylene Glycol or PG is a much thinner liquid and produces very little vapour on exhale. PG attributes to what we call the “throat hit”, which can vary in intensity depending on the nicotine strength. PG helps to simulate that “cigarette style” hit. Without the other 6000 chemicals of course.
