My view - just like my view with marijuana - we need to do a better job of quantifying the negative impacts of addiction. It is fundamentally a bad thing for your body to be addicted to something, and we normalize that view by engaging in whataboutism; oh, it's just coffee, it's just sugar, it's better than cigarettes and on and on.
There hasn't been enough research on it, it's certainly more opaque for consumers to really know where the ingredients are being sourced and how much nicotine they're actually receiving. These are all bad things, even if it's "better" than combustibles.
That's of course in addition to the extreme shittiness of these companies blatantly advertising to kids, but that's another argument altogether.
