VG stands for vegetable glycerin, which is used along with PG to make vape juice. VG is made entirely from vegetable oils and, therefore, is completely safe to consume and vegan-friendly. Usually, there is anything from 50/50 to 70/30 VG to PG. That is because some people are mildly allergic to PG, and it irritates their throats. Vape juice with more VG will feel better for those individuals. VG is much thicker than PG, so it can only be used in certain atomizers. Otherwise, the vape can become clogged. Be sure that you ask a Kure associate which vape juice will be best for you and the devices you have.
