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.

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

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

Is it like a catalyst?

Sometimes, but not always. In chemistry, catalysts can help initiate or facilitate chemical reactions, but there is often another input required to kick start the process (e.g. heat).

We know that cannabis can act as a catalyst for schizophrenia, but we also know that not everyone who is predisposed to schizophrenia develops it 100% of the time after cannabis use. There are degrees of predisposition, and a bunch of other factors that contribute to this.

Does a freezer make ice, or does water make ice?

A trigger requires a gun to actually do anything.

> at-birth mental health issues

many of the most common mental health conditions (personality disorders, and schizophrenia) don't appear till the end of adolescence.

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 is a weird argument, because “trigger” and “cause” here are exact synonyms.

See, you just have to draw a causal diagram and enumerate all possible counterfactual worlds…

Your analogy isn't equivalent to what was said. To be 1-1 with the OP, you'd be arguing that the lighter caused something to be flammable. Causing a *fire* is something else.

Similarly someone can be schizophrenic but have an *episode* caused by weed. The weed didn't make them schizophrenic but it did cause an episode to happen.

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