I was fairly sure I'd seen the overall numbers and that they'd risen but of course now I cannot find that. However I found data that supports my main point there which is that loads of kids are vaping and we have good reason to think they'd have avoided cigarettes if vapes weren't a thing:

From 2011 to 2022, current use of electronic cigarettes:

Increased 667% among middle school students, from 0.6% to 4.6%.

Increased 567% among high school students, from 1.5% to 10.0%. This was a 64% decrease from the peak rate of 27.5% in 2019.

In 2022, more than 825,000 children started using e-cigarettes, or more than 2,200 per day.
