My understanding is that schizophernia is a predisposed condition. Cannabis can trigger it but not really cause it. (That's at least what I got from talking to a professional). One clue to find out whether you are predisposed is if you have someone in the family (related genetically) who has at-birth mental health issues. Then stay a gazillion miles clear of any drugs.

If you don’t have it and then taking it makes you have it then that is causing it

Right. Which is why there’s no science to back up the claim that marijuana causes schizophrenia.

> My understanding is that schizophernia is a predisposed condition. Cannabis can trigger it but not really cause it. If something is flammable, and so predisposed to burning, and you hold a lit match to it, you did cause the fire. You didn't just trigger it.

This allegory only works if you’re willing to accept that some people are inflammable.

There's a big difference between a direct cause and a potential trigger for a condition with specific endogenous prerequisites.

There is no universal trend of people consuming cannabis and developing schizophrenia.

Psychosis can do a lot of damage. I had a 4-month-long psychotic break that eventually led to me being diagnosed bipolar. It several years to recover from but I think some of the damage is permanent. I feel like I've lost a lot of memory function but I can't remember what things were like before. And it's difficult to separate that out from medication side-effects at this point. What I do know is caffeine gives me pa…

First person that I read about also having a problem with coffee and even with decaf. For me it started inducing anxiety like effects and gives me insomnia now if I accidentally eat a tiramisu or something containing a bit of it. Haven’t found anything that one can get an acquired caffeine sensitivity, but I guess there is not much research. I didn’t have an episode, but it did start during some more mentally challen…

Sorry, neurotoxic ? That's not a settled debate; not remotely. There are many reasons to believe cannabis is neuroprotective. Especially when using safe, high CBD, high cannabinoid varieties; a rather vital distinction. And it's not semantics, because you can't make the assumption that people would "never have become psychotic without the drug". On a population scale, such an effect would have stood out by now if it…

> That's not a settled debate; not remotely. In my opinion it is neurotoxic, based on studies I have seen (such as this one that we are commenting on) plus my own direct personal experience. Even without the psychoactive components, the smoke is carcinogenic (like tobacco) and toxic to all cells, including neurons.

>plus my own direct personal experience

How do you measure neurotoxicity on yourself?

>Go take a massive bong hit, then tell me your mind and lungs feel healthy.

Smoking is far from the only way to consume cannabis.

>the smoke is carcinogenic (like tobacco)

All smoke is carcinogenic, because it is smoke. This is not a function of cannabis, but a function of organic matter.

Marijuana causing schizophrenia would be easy to determine if nobody was schizophrenic before the reefer. Before then they were just possessed by demons.

If you consume it, and it subjectively and objectively harms your mental health and cognitive abilities, then basic common sense and reasoning tells you it is harmful to the brain (neurotoxic).

This is my opinion based on my experience. If you smoked this shit and it gave you an extra 20 IQ point boost, then congratulations.

> All smoke is carcinogenic, because it is smoke.

That's the point. Neurons don't get healthier from carcinogens.

> Cannabis is blatantly toxic filth No, it isn't. It's medicine, and remarkably harmless recreation. It saves many lives, and enhances quality of life for millions of people. It has a smorgasbord of health benefits. It does have side effects, and drawbacks. It's not a panacea, and it doesn't suit every one. It's not for kids (except when it's medically worth it). But calling it "blatantly toxic filth" is wildly infla…

Original journal article (apparently not linked to in the Bloomberg piece): Association between cannabis use disorder and schizophrenia stronger in young males than in females (May 4 2023) https://www.cambridge.org/core/journals/psychological-medici... Interestingly, the journal article doesn't bother to mention how cannabis use disorder (CUD) is defined; however, Bloomberg's description "frequent use despite negativ…

I'll save everyone a click: yes, this is a case of 'correlation != causation'. We know extremely well, for a fact, that at least a good chunk of the SCZ/marijuana use relationship is confounded/reverse causation. The authors do little to improve over the known-wrong simple correlation strategy. This is especially lame when they have access to the Danish population registry with its rich metadata and very large _n_, a…

I'll save everyone a click: yes, this is a case of 'correlation != causation'.

The authors (whose freshman stats classes were presumably as good as yours) were evidently well aware of this distinction - which is why they took the trouble to say 'association' rather than 'causation' in the title.

So the pedantry here seems rather misplaced.
