Its a combination of a few different things. The flavors make it more attractive to kids. The non-combustible method of inhalation means it can be safely/cleanly vaped indoors, say in school bathrooms, and you don't have to waste a whole cigarette just for one puff. They're also ridiculously easy to find online under 18; Juul themselves does digital age verification, but plenty of retailers don't. They're being asked to prove that the device helps adult smokers more-so than it hurts new smokers. The keyword is "more-so", because if these statistics suggest that Juul's uptake in adult users is lower than the FDA's statistics on high school usage, or if Juul can't prove that the vast majority of their users were former smokers rather than new users at any age, or if Juul can't present evidence that vape devices (especially their ultra concentrated 5% nic salt formula) are safe, they're finished. And they'll take the rest of the vape industry down with them.
