To fair and accurate I cherry picked TWO studies

You didn't cite or include a link to even one. You just tossed a load of bullshit here and hoped it would stick.

By the way... one of those cherry picked links goes to Scientific American's website. Hard to do better than that even if you are picking cherries.

You have the power to search for "cannabis iq" and find the literature.

Generally I expect some basic scientific literacy on HN. But of course I should have learned by now to expect science denialism when ego is at stake.

If you want a concrete source look at any of the studies that cite the twin studies, including the meta-analysis from this year.

Scientific American is not a peer reviewed publication. They are science journalism and they aren't even particularly careful about their analysis. They posted an article in 2017 claiming cannabis might make you smarter:

They might be right about "makes you smarter". I mean, here you are complaining that SA isn't "peer reviewed", which is pretty stupid because they're publishing the results of studies done by others, not doing or controlling them.

Ha. I honestly don't think I've ever seen such a childish response on HN.
