Juul's mint flavor has become the most popular e-cigarette flavor for teens in 12th and 10th grades and the second most popular in 8th grade, an NIH-funded study published in JAMA shows. A second JAMA study found that mint and menthol's popularity among all e-cigarette brands is also rising.

Why it matters: The Trump administration is expected to move forward this week with a ban on flavored vape products, except for tobacco and menthol flavors, and Juul has already said it will stop selling all flavors except tobacco, mint and menthol.

By the numbers: About 1.6 million high school and middle school students have used fruit-flavored e-cigarettes in the last 30 days. About 1.2 million use either menthol or mint flavors, one of the studies notes.

Meanwhile, the Food and Drug Administration has been investigating Juul's advertising and marketing practices.

  • Reuters reported Tuesday that in 2015, Juul had disregarded early evidence it was enticing teens to use its product and ultimately become addicted. Its nicotine blend was so potent, engineers tried to create a fail safe with a lesser a dosage. The notion was delayed.

What to watch: Will teens switch to menthol- or tobacco-flavored vape pods, when that's all that's left?

The Justice Department and 11 states Tuesday filed an antitrust lawsuit against Google, accusing the company of using anticompetitive tactics to illegally monopolize the online search and search advertising markets.

Why it matters: The long-awaited suit is Washington's first major blow against the tech giants that many on both the right and left argue have grown too large and powerful. Still, this is just step one in what could be a lengthy and messy court battle.
