I’m sorry but this comment is just very misinformed.

Why would people not just switch to unflavored vaping instead of smoking? […] Would you not switch to flavorless?

Because there is no such thing as “unflavored vaping”. Just forced flavors.

the flavored ones are tailored towards younger consumers

Also just untrue. I’m an ex smoker, but just can’t stand tobacco flavored liquids, or menthol ones. Some vapers like those, others prefer fruits and cakes. And if you’re already vaping, why wouldn’t you choose what you like best? Especially considering the alternative is cigarettes.
