I stopped smoking 9 years ago because of bronchitis or something every year. The last year was really bad. Plus it's too expensive. Picked up vaping and haven't had any lung issues since. I make my own liquid that's 2.5% nicotine so not sure if I'm even feeling it or if it's a placebo.
I don't think we fully know the long term effects since it's still relatively new. People can smoke cigarettes for decades before getting serious health problems/death.
This is where cool people write stuff.
