amounts of carcinogens that we find in vapors' bodies, they're actually kind of low.

And as Leon puts it, the dose makes the poison, right?

And that's just sort of a general rule in epidemiology that the more you're exposed to something that has some kind of risk, the more likely you are to develop

but that disease, you know, and so with vaping.

Now, I mean, Leon did say, he agrees, it's totally possible vaping could have a risk of causing cancer.

He just doesn't think that we currently have the evidence to support saying that for sure, yes, we know now vaping does cause cancer.

And one reason is we actually don't have much data in actual human beings with actual cancer.

Yes.

And I really went looking for other evidence that didn't make it in Bernard's review of people who vape getting cancer.

And I did find some studies, and they find things like people who vape are more likely to have lung cancer, for example.

But in all the studies that I could find, a lot of the vapers also smokes or used to smoke.

Right.

So we don't know if the cancer came from the vaping or the smoking.

It's messy.

And that makes it a real mess.

Yeah.

And so without more like evidence in people actually getting cancer, I don't think that these authors should have said that they have produced the, this is what they said in a press release.

They call it the most definitive determination that those who vape are at increased risk of cancer compared to those who don't.

I think that is an overstatement.

Strong words.
