Because there are so many different e-liquids on the market, it would be difficult to say with absolute certainty that ALL e-liquids are vegan. However, most e-liquids are probably vegan simply based on the ingredients they have. E-liquids have a base of vegetable glycerine (VG), propylene glycol (PG) or a combination of both.
Vegetable glycerine made from plant oils (typically palm oil, soy or coconut oil). Propylene glycol is an organic compound derived from petroleum products. E-liquids also contain nicotine (unless you vape zero nic), which is an addictive substance found in nightshade plants like tobacco. Then, there is the food-grade flavoring, which is also typically made from plant sources but may occasionally contain animal products. Thus, it would be best to check with your e-liquid manufacturer about the specific ingredients used in the flavoring.
Additionally, there is also a chance that some of the ingredients in your vape juices may have been tested on animals. So this is something else you may want to check.
