Sure, but I think in this case we're trying to convince OP to not do either. Vaping is safer than smoking, it's not safe. If you currently smoke and can't/won't quit the nicotine, switch to vaping. Don't start vaping if you're not already a cigarette smoker.

I would like to see some better quality studies, but those are in short supply because of the amount of bullshit studies funded by people who profit from big tobacco. I think there was one good study about how nicotine specifically was bad for cardiovascular health?
