> we didn’t have modern laboratory science when tobacco was brought over to Europe
Modern laboratory science is no help in figuring out fast whether vaping is harmful, because we don't understand how the human body works well enough to do laboratory tests that will tell us. So we're reduced to basically what we used to show that smoking was harmful: long-term data collection and analysis.
> My lungs function so much better now that it’s easily discernible to me that smoking irritates lungs far more than vaping.
Saying that vaping is less harmful than smoking (which is probably true) is a much weaker statement than saying that there's zero indication that vaping is harmful, so there's no reason to worry about it, which is the claim I was responding to.
