To be clear, there is science that is compatible with THC increasing the risk of psychosis (and perhaps that CBD is protective). I would agree that some are self medicating, but the data also shows that dosage, THC/CBD mixture, and age of use each elevate psychosis risk over random controls [1][2]. It would be great to do double blinded experiments to test this more definitely, but we don't due to unethical reasons. I think the differential legalization will provide useful data along those lines, though it will take some years. I also think it's important to distinguish between THC "exacerbating" an existing mental illness and triggering psychosis in otherwise healthy people who have a predisposition, due to genes and early life experience. We still don't have a clear idea exactly how to say who's predisposed. Plenty of reasons to take caution, in my opinion.
