#2What a strange study. Only less than 1% even developed these conditions.
They excluded people with a mental health diagnosis, and their data for already having symptoms was having a diagnosis?
Why do they assume this shows marihuana causes mental disorders, as opposed to being undiagnosed whilst already showing symptoms leads to self medication, for example?
I’m sorry, but most psychology research is just so incredibly badly done.

#3"But by excluding teens who were already showing mental health symptoms, the new study points to a potential causal link between cannabis use and later mental health diagnoses. Additional research is needed to understand the link fully."
Hm, but this does not exclude the possibility that the being prone to mental illness comes with a little bit higher tendency to consume cannabis...

#4Unless you blind this, I’m not sure it’s possible to get past the correlation or causation problem. Weed use is not yet so destigmatized for teens that usage itself is not a marker of deviance (in the math sense, not any kind of judgement).

#6I used to read forums for schizophrenics (self disorders fascinate me, look the term up if you want to understand schizophrenia), and it was the consensus there that out of all the recreational drugs cannabis caused the greatest deterioration in one's mental state. Those are generally fairly sick people, but I don't think one can just ignore this signal. I personally went catatonic once after consumption, and I'm not schizophrenic at all. And that was in Amsterdam, so it wasn't some trash spiced up by a 17-years old dealer with whatever he found in his grandma's medical cabinet.

When I read this article the other day I had the exact same thought. Is this simply correlation, or is it causation? Is teenage usage an indicator of a possible underlying condition that hasn’t fully manifest? Is it an early form of self medication?

#9The NPR article seems to confuse causation and correlation.
The actual paper doesn't, and merely implies correlation. Which is fascinating (and well-known) and might still prove useful in one way or another.

#10The correlation used to cite heavy (daily repeated administration across the day; what the kids call "the chronic.")
But now its just any degree of use.
I should add that I happen to know of more than one heavy user who subsequently progressed to Schizophrenia or bipolar disorders so I don't personally doubt the cause and effect.
But this blanket correlation seems to me to be overbroad.
