Rather, vaping is (from what we know so far) legitimately a far, far healthier alternative to smoking cigarettes. The biggest health risk by far isn't the nicotine, it's the smoke, which vaping doesn't have.
It's been framed as a public health question since the very beginning: do the population-wide large health benefits of smokers who can't quit then switching to vaping, outweigh the (as currently understood) much smaller potential health problems with vaping, but which may be taken up by many people who otherwise wouldn't smoke at all? It's a balance of harms.
What I've heard about Juul addiction among college-age kids sounds a little scary. (But then in my generation it was scary binge drinking, and that's fallen significantly over the past 10 years.)
But at the same time, I've seen friends finally be able to give up smoking for vaping, which can only be a good thing given what we know right now.
