It's more appealing to everyone, irrespective of age. Wikipedia suggests that it's been popular since the 19th century at latest. It was flavoured cigarillos that were the first tobacco products that tempted me, at a young age but not a child. Later, when I was much old, if pleasingly-flavoured vapes had been unavailable I would've had a much more difficult time quitting the nicotine.
But anyway, it's the misguided notion that enjoying things which taste good is childish that I find offensive. Advocate for banning all tobacco and I can't really say you're wrong to suggest it, but don't fall for that nonsense.
