This article is all over the place.

I wanted to see the data that supported the idea that "Among children ages 11 to 14, girls had a particularly striking rise: a 111% average increase from 2019 to 2022".

They link to an NBC News article in that sentence.

Problem is, the only mention of girls and marijuana use I can find at that article says:

> Only 16% [of girls surveyed] said they currently use marijuana, compared with 23% in 2011.

The survey is CDC's 2021 Youth Risk Behavior Survey, presumably conducted in 2021.

With that in mind, how does the math of "111% average increase from 2019 to 2022" work? My assumption is that the data for 2019 to 2022 shows it, but where's that data?
