Is there a difference between Vegetable Glycerin and Glycerin with DIY & Vaping ?
Vegetable Glycerin that is USP grade should be used for vaping. Read the ingredients on the Glycerin to see if it is actually vegetable glycerin. Some glycerin is animal based and not vegetable based.
In the U.S.A. we use USP which stands for "United States Pharmacopeia" and deems it safe. I don't know what is used in other countries.
It may be SFDA which is Saudi Food And Drug Authority
