Many vapers have asked what is in nicotine vap liquid, so we thought to take a look. We chose one of the top sellers of nicotine vap to take a look. Analysis of commercial products can remove the advertising glamour to reveal what is really in the bottle. The product promised natural and artificial flavors, nicotine and a smooth experience. Well the liquid did in fact contain nicotine at a level as labeled, the rest of the product is unimpressive. There is a very large amount of glycerine and other semi volatile liquid solvent, and artificial flavor-not much else. The amount of glycerine inhaled is so much more than the nicotine, it makes you wonder why are you inhaling all that glycerine if your goal is nicotine.
