Juul

While adolescents are canny enough to hide their Juuls from you, they don't really believe that vaping is harmful.

A Juul is an e-cigarette that looks like a USB thumb drive and uses a "pod" system for refills.

[Jason] Jeong, the Cornell graduate, says his peers stopped using Juuls when the company discontinued its popular flavors. People liked mint, which remained on the shelves, but no one wanted to puff on a tobacco-flavored Juul.

But by spring of that year, nobody had a lighter – everyone had started vaping instead. So I followed my friends and jumped off the cliff: I bought a Juul.

Just this week, while taking a history from a 19-year-old young man, I asked him if he smoked cigarettes. The answer was no. I then asked him if he vaped. He answered that he used a Juul. When asked how many times a day, he replied that he Juuled continuously, all day.

I took my tween to a concert last month at the state fair in Minnesota, and we were possibly the only two people in the crowd near the stage who weren't Juuling.

When I Juuled, I didn't take smoke breaks – I had grown accustomed to puffing away all day at my desk, and even more on stressful deadlines.

His life: […] He [Antoni Porowski] knows he shouldn't, but he Juuls (mint, in case you were wondering).

That is the most important change over the last couple weeks for me... Do you vape? Do you Juul? Very bluntly. It's part of what I ask now.

Perhaps the most fascinating, and darkly comedic, anecdote in "The Devil's Playbook" comes when Juul meets some of its fiercest critics: several wealthy California financiers who become incensed when they learn that their own kids and their kids' friends are Juuling.
