Pretty sure no legitimate nicotine vapor devices ever used or contained vitamin e.
Nor will they.
Sure, there’s some unknowns in the industry, but it’s been around for 20 years now. The basic forms of e liquid are all GRAS, and unless you are burning the cap out of your coil or using nonstandard ingredients, this is a much safer means of nicotine compared to smoking.
No one in their mind will say it’s safe or healthy, but it’s a means of lowering risk.
