What 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.

The experiment to get to the root of this is forbidden. They’d have to perform double blind (kind of a fools errand when being high is so obvious) experiment where they gave matched patients and controls either weed or placebo. Then they’d measure effects long term with enough of a sample size to overpower latent factors.

But this study will never be approved for obvious reasons so we will never know one way or another.

Science has to start somewhere. Actually proving a causation is hard and expensive and usually needs to be very targeted. You need these kind of feeler studies to find promising links to target for further research.

This is why science is so much about standing on the shoulders of giants.

It is wrong for journalists to report these low rigor, survey studies as the meaningful results they always seem to report, but for some reason Women's Health can keep saying "Chocolate causes cancer actually chocolate cures cancer actually chocolate has no effect on cancer actually...." for decades and people don't stop buying it and instead insist that the scientists are the ones lying
