I think it's pretty unquestionable that smoking is worse for the lungs, and almost certainly worse overall than vaping. But smoking was on the decline; if vaping had never existed or gone mainstream, eventually very few people would have smoked. Instead now, there are many young people becoming addicted to nicotine via vaping. That's almost certainly better than if they were smoking instead, but it's likely worse than if they weren't using a nicotine product at all. Now, you could argue that there's little evidence of nicotine being harmful aside from being highly addictive (although even then there would be an economic argument to be made), but if there is any harm, the addictive nature will make sure that harm is long-lasting.
