After more than 30 years of daily cannabis use with occasional tolerance breaks I recently took an IQ test along with a series of mental evaluations and was in the 99th percentile. So maybe cannabis took me down just enough to avoid being one of those Mensa jerks?

It might be interesting and revealing to see the correlation between casual cannabis dismissal and low or reduced IQ, but of course that goes against the popular narrative and looking for potential errors isn't where most scientists focus since that isn't super glamorous or likely to get citations from publication.

What do you mean by casual cannabis dismissal?

That’s an excellent line of research to dive down. You’re going to get some folks here sweating, though.

Yeah, I've heard people say that all my life. Some folks love to believe that. But there's nothing that really backs that up with solid proof. A lot of them whom I've heard say that were coke users, which to me would indicate a lack of intelligence.

Here's a couple studies that seem to disprove that myth about weed users but, like all of these studies, they really cannot claim to be conclusive. Still better than most I've seen though:

The "some folks" include the scientists who actually study this.

But good job cherry picking a study. Hope it makes you feel better.

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.
