Vaping is likely to cause lung and oral cancer.

The conclusion is unavoidable.

We can hardly say that e-cigarettes are somehow safer than conventional cigarettes.

Good morning.

Microplastics, pesticides in soil.

Those chemicals are detectable.

In other words, they have been absorbed into the body and not just to exhale.

So strike one.

Individual dentists say, I saw a patient with oral cancer and this patient never smoked, which is the well-known cause of oral cancer, but he or she did vape and I suspect the vaping was connected with the cancer.

So all of that data, the laboratory data, the biomarker data, the animal data, the case reports, all of that taken together lead us inexorably to the conclusion that vaping is likely to cause oral and lung cancer.

Yes.

The criticisms are absurd and I treat them with complete contempt.

You're serious?

You're saying we wait around until enough people are dead from lung cancer before we do anything?

Is that what you're suggesting?

Look, the definitive proof will take decades, okay?

It took just on 100 years to definitively prove that cigarettes caused cancer.

Cigarettes by that time had become the major known cause of cancer in the world.
