A recent study by the Journal of the American College of Cardiology has brought popular e-liquid flavors to the forefront. The study examined six different flavors to see what effect they had on the cells. The flavors that were tested included caramel, cinnamon fruit, menthol sweet tobacco, butterscotch, and vanilla. The researchers also looked at the effects of different nicotine. The journal states that menthol and Cinnamon flavors can be harmful to cells. Cinnamon, menthol, and other flavors “disrupted” the ability of cultured cells to create capillary-like structures.

They help them on their journey to nicotine-free.

Many household products, including toothpaste, gum, and nasal sprays, as well as essential oils, contain the flavors that are being studied. No surprise, then, that these flavors are also popular in vape fluids and e-cigarettes. It begs the question – just how dangerous are these flavors? We suggest that cinnamon and menthol be avoided in any form until more studies are done. You can still find many other flavors to help you quit smoking.
