Is VG Safe for Vaping?

As stated, VG is a carbohydrate extracted from plant oils and used in the e-liquid when it comes to the vaping world. The vapes are achieved through a mixture of Propylene glycol (PG) and VG in the ratio of 3:1.

VG is always considered as safe for consumption and has also been assessed for vaping. Most e-liquids contain at least 80%-92% vegetable glycerin. This is the content that produces the smoke-like vapor that is exhaled from the e-cigarette. 

VG contains glycerol one of the most benign organic liquid that makes VG hypo-allergic, non-carcinogenic, non-mutagenic and non-teratogenic. This makes it more metabolic thus easily metabolized in your system, making it safer.
