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?

Why it matters: The CIA has conducted disruptive covert cyber operations against Iran and Russia since the signing of this presidential finding, said former officials.

Tech was the first industry to send its workers home when COVID-19 first hit the U.S., and it has been among the most cautious in bringing workers back. Even still, many companies are realizing that their reopening plans from as recently as a few weeks ago are now too optimistic.

Why it matters: Crafting reopening plans gave tech firms a chance to bolster their leadership and model the beginnings of a path back to normalcy for other office workers. Their decision to pause those plans is the latest sign that normalcy is likely to remain elusive in the U.S.
