Yeah well the “problem” if you want to call it that is that e cigarettes don’t harm your lungs anywhere near the level of tobacco smoke.
There is no “these are your lungs on vape” bc frankly your lungs will look pretty normal.
If you’re interested in the data, look at the studies that have come out of the UK and the statements their public health officials have put out.
There is a public knowledge problem in the US regarding vaping because of reporting on the short lived emergence of so called “EVALI” (ecig/vaping associated lung injury) which hospitalized some teenagers and adults.
EVALI was determined to be caused by Vitamin E Acetate which was a flavoring additive used in some illegal THC vapes. Once the cause was determined, even the shady illegal vape makers stopped using that ingredient. But the reputational damage to ecigs remained. EVALI was a US only problem and a short lived one at that.
Data broadly shows that ecigs are a much safer alternative to combustible cigarettes for nicotine consumption.

It wasn't even a flavoring additive. It was sold under the name "Honey Cut" and was used to dilute cannabis oil to rip off customers. That's why it never showed up in the legal market.
