What is vegetable glycerine (VG) and propylene glycol (PG)?
Both PG and VG are non-toxic, organic compounds that are considered safe for human consumption. Both have been widely used for decades as food additives in a variety of commercially available food products such as cheese, cereal, ice cream and soft drinks. PG and VG make up the base of all e-liquids and are what produce the throat hit and vapour clouds when vaping.
