Yes.

But this is totally ignoring the fact that there is a potential benefit of vaping, and that's for people who smoke.

And so if you're evaluating vaping as its own thing, ignoring the fact that its major purpose is as a smoking cessation device to get people to stop smoking, when it's very hard to do that, you're missing like a huge part of the argument here.

Wild claim.

That's where scientists put their wild claims is in the last line of their last paragraph.

So I looked into that claim, and what's interesting is that there are other scientists who say we should rethink this idea that vaping is flat out better for you compared to smoking.

Well, I mean...

In Bernard's paper, one of the things he cites to make this case that vaping is really bad is a review paper that came out a couple years ago.

And this one was looking mostly at heart and lung problems in people who smoke or vape.

So for that, we do actually have studies in real people.

And this review paper concluded that smoking and vaping are equally bad for cardiovascular disease, stroke, and metabolic dysfunction.

Wow.

That's stuff that can lead to like diabetes and stuff.

Wow.

And that's a pretty big deal.

And so from Bernard's perspective, if he's pretty sure that vaping is on its own cancer-causing, and this other body of research says vaping on its own is heart disease-causing, boom, like death to vaping.

Why is vaping so bad for your heart?

One reason is that nicotine itself is a vasoconstrictor, so it could, like, tighten your blood vessels, and you can imagine how that would be bad for your cardiovascular system.

Yeah, and vapes have a surprisingly high amount of nicotine in them.

Yes, and getting higher all the time.
