Exposure to vaping products — through friends, endorsements on social media or branded merchandise — makes students much more likely to vape, according to a study published in JAMA on Wednesday.

Driving the news: The study was published the same day Massachusetts Attorney General Maura Healey sued Juul, saying its early marketing campaign targeted teenagers with celebrity endorsements and ads on popular sites.

Between the lines: The JAMA study, which polled more than 4,000 students in New Jersey, confirmed that Juul is especially popular with teens.

  • Nearly 90% of high school e-cigarette users said they had used a Juul product in the past 30 days.

U.S. government bonds could breakout further after yields on the benchmark 10-year Treasury note ticked up to their highest since early June last week.

But, but, but: Strategists say this move is about an improving outlook for economic growth rather than just inflation.

The dangerous instability of school re-openings

Schools across the country have flip-flopped between in-person and remote learning — and that instability is taking a toll on students' ability to learn and their mental health.

The big picture: While companies were able to set long timelines for their return, schools — under immense political and social strain — had to rush to figure out how to reopen. The cobbled-together approach has hurt students, parents and teachers alike.
