The conversation was about a single vape, and casual use, in the first place.
And yeah, I bet that's happened before, just like I bet a day-trader who ran on margin has lost all of his savings, house, cars, and wages through garnishment. That doesn't mean it's how 99% of situations, even in trading on margin, goes.
Even as it relates to underage dealers - even the stupid ones, a very few amount of teens buy in bulk - let alone do it only to fail on sales and get coerced into crime for payback. Not to downplay, the old "ATL" story like that is definitely real shit for illicit drug selling. But for vapes/alcohol/sanctioned (but legal and readily-available) substances? C'mon now. The market's there, but the incentives for coercion (due to the commodities being readily-available) are not.
I'd sooner assume that a story like that is a teen that's making a BS "blame the system" excuse for the fact that they actually bought vapes in bulk, squared it away, wanted to make more money than that hustle could offer, and voluntarily graduated to higher crime on their own. Fair play if they pull the excuse off, though - they've got us talking about it.
