VG is also recognized as safe to ingest as it’s extracted from vegetable oil. It’s responsible for giving vape clouds their sweetness and large white-cloud thickness. It also provides a smoother hit compared to propylene glycol. Vegetable glycerin is a favorite amongst new vapers as it doesn’t scratch the throat as much. It’s also a lot sweeter in taste. However, it is a thicker liquid and does require a bit of extra cleaner to avoid your CBD vape pen from getting clogged.
