Turns out the recreational drugs were never good for you. Is there a single recreational popular >100M user drug that’s good for most? Maybe coffee? It’s a shame there are so many with reduced brain function and IQ. Next thing will be shocking studies showing regular shroom usage is bad too, lol. It is a shame we are in a post truth society. People burying their heads in the sand.

This is such an obvious problem to anyone who is above the age of 25.

All of my friends who were real big into weed in high school are all pretty bad at remembering things, most work dead end jobs and are generally unmotivated The ones who started the youngest are in rough shape mentally. Every single one of my friends who still lives with their parents smokes multiple times daily.

Out of all of them, only one is successful, and It's because he bought BTC in 2014 and still has around 20 of them.

I have no doubt, smoking when you are <21 is a huge problem long term.

dang what about other people outside your sample size that did smoke under 18 and then became successful? what was your control group also?

Effect size of -0.3 standard deviations on working memory. P value of .02 corrected for FDR. Not huge. Sounds believable to me.

Small effect size, and one I'd expect to be comparable to a lot of other things, like similar alcohol use, sleep deprivation, mood disorders, etc.

Hard as it may be for some to believe, not all people are trying to optimize for maximum brain function, evidence suggests that a vast swathe of humanity tries very hard to actively REDUCE their function on a recreational basis.

Earlier quoted context omitted.

A great deal of both the psychological and the drug policy communities disagree with you on this point.

Point out the problems caused by marijuana during the thousands of years of unregulated use. The regulatory environment is the main driver for the problems caused by most drugs in the modern world. If it weren't illegal to use/possess/sell, people would largely not be stealing or killing or doing other antisocial things in order to do so. I'm not really a fan of decriminalization as a panacea to societal problems around drugs, but criminalization was the cause of most of those problems.

It's quite reminiscent of how long it took people to associate smoking with emphysema and lung disease. In hindsight it seems so obvious! But building evidence for even obvious conclusions can be surprisingly hard.

It would be more shocking if cannabis didn't do this.

Most adolescents who get heavily into any drug generally have issues--this includes alcohol and nicotine, as well.

"Study [..] found that the drug can reduce brain function"

Causal language in news on correlational (case-control) studies should be a crime.

This is a brazen misrepresentation of the results. The direction of the causal arrow (cannabis -> dumb vs dumb -> cannabis)--or if there even is a causal arrow (other factor(s) -> cannabis+dumb)--is purely editorialization and born of a severe lack of journalistic integrity.
