Cancer from cigarettes is largely linked to a small subset of compounds produced by the combustion of tobacco. Appropriately named as carcinogens. Those are the cancer-causing compounds that link cigarettes to cancer.
Vaping, by contrast, is propylene glycol and vegetable glycerine (PG and VG), as the base substance (which is basically the same stuff they use in fog machines, and people breathe that constantly without any directly related issues). PG/VG makes up more than 90% of the vape liquid, by volume. The remaining 10% is usually a solution of PG/VG mixed with nicotine concentrate to make the whole solution have a particular % of nicotine content, usually measured in mg per ml, and the last few percentile are flavorings.
So from a 60ml bottle, more than 55ml will be the VG/PG base fluid, 3-4 mL will be the nicotine concentrate, and the remainder will be flavoring.
Apart from the flavor ingredients: VG, PG, and nicotine, to date, have no carcinogenic characteristics and have not been linked to cancer (to the best of my knowledge). So over 95% of the volume of the liquid is known to not be cancer causing, the rest is usually food-grade flavoring.
Needless to say, food-grade flavoring is generally not carcinogenic.
Has that been proven though? I don’t think there’s yet any sufficient long-term research to know the full risks of vaping.
More or Less, yes, it has.
