That 90% is admittedly going by memory of statistical analysis that I’m now unable to find amongst all the anti-vape misinformation and data that focuses only on how many vape and doesn’t show the age distribution.

I am not saying you are lying, I know it is impossible to memorize all studies you ever read. On the other hand this makes your 90% pretty useless, as it is not clear what is counted here. You mentioning anti-vape misinformtion seems to me like you could be a bit biased, defending vaping for whatever reason.

That sounds ridiculously high. The highest I’ve seen for 2018 was 2.9%. There’s no way it went from that to 20% in just two years.

Ok but that is not how studies work. I am not from the US, but the affiliations of the study I linked seem to be pretty credible:

Office on Smoking and Health, National Center for Chronic Disease Prevention and Health Promotion, CDC; Center for Tobacco Products, Food and Drug Administration, Silver Spring, Maryland.

The “myths debunked” may be an interesting read, but it does not contribute anything useful to the discussion.

I don’t want to fight and as a non-smoker I am absolutely open to get convinced by you if you can provide some substancial information. However downvoting me is not really a strong argument.
