Well the fact that there's not one recorded death except by explosions due to owners' ignorance and negligence, and that ALL the studies haven't pointed out to any severe health effect, and that it's approved by the FDA are good enough to meCitation needed.
Nicotine alone has no negative effects on health really. It's the vehicle that's the problem.Idk since I ditched nicotine my health got a lot better, mental health also
