How to Tell if Vape Juice Contains Synthetic Nicotine

All vape liquids and products containing e-liquids (like disposables) must follow specific legal guidelines to be offered for sale. One of these guidelines is displaying a complete and accurate list of ingredients on the packaging or label. If Synthetic Nicotine has been used in a vape liquid, it cannot be listed as just “nicotine”.

Instead, it can be listed in the ingredients as TFN, TF Nicotine, NTN, or simply as Synthetic Nicotine. TFN stands for Tobacco Free Nicotine, and NTN is Non-Tobacco Nicotine, both of which are now recognized terms within the tobacco and vape industries (and the lobbying bodies that oppose them.)

Black-market vape juice, which is unlikely to abide by U.S. regulations, may incorrectly label plant-derived nicotine as synthetic or TF nicotine. And although, if that were the case, it would have little effect on your health, it’s yet another reason to make sure you buy your ejuice from reputable retailers.
