Vapes enjoyed a fuckton of marketing from people proudly proclaiming "There is no proof that these new things cause cancer!" Followed by a decade of company funded "Nuh-uh!" ambiguous refutations and lobbying campaigns to kill any kind of contrary studies.

Like, I get the impulse to say "No duh". But I doubt you're listening to a congo line of Joe Rogan and Tucker Carlson ad men telling you that vaping is the safest, bestest, most liberating way to consume your drug of choice.
