The ONDCP twitter account just posted a very interesting graph on past-month marijuana use rates in the 12-17 year old adolescent population.

This dovetails very nicely with a factoid being twittered today in the #MTF2013 hashtag which is covering the release of the mid-term data from the Monitoring the Future project.

this actually surprised me. That it was so low.

Of course, one’s first suspicion is that states which are liberal enough to pass medical marijuana laws might have adolescent populations that are more likely to smoke marijuana anyway, i.e., regardless of the medical legalization. Be nice to see a workup on teen marijuana use in these states before and after they legalized medical marijuana.
