Can't see that the study is solid evidence for that. Very likely yes, but teenagers who have a high risk of developing psychic disorder might also have a higher tendency to try out canabis (and keep using it)

They're controlling for that...
The real sticking point is another way to say a rate doubled, is that it increased from 0.0004% rate to 0.0008% rate, is an increase of 0.0004%.
That's most likely going on here, and is something we've always known.
It's not like someone is born destined to experience these conditions, people are just suspectable at various rates, so for some people right on the line, weird shit can tip them over when they wouldn't have before.
Do the same test with sugar or caffeine and your likely to get similar results even, but good luck finding control groups that aren't drastically different in other ways.
We also can't control the study the other way, and force kids to smoke weed
Anyone acting like these types of studies proves anything safe or unsafe, at best doesn't know what they're talking about.
You can only controll for known previous conditions.
And genes could be a driving factor.
The last paragraph in the article seems to indicate that being born into low income families increases psychic health risks.
Fully agree that studies like these are pretty much useless. They are the reason we get media outlets to proclaim bullshit like "drinking 1 glass of wine everyday is good for your heart"
I could quote pieces of the article until (hopefully) you read all the bits and understand...
But can you try reading the article first?
From the study itself
unmeasured confounding (eg, adverse childhood experiences, genetic risk, parent mental health) cannot be ruled out.
