Thought I'd share this interesting take: > Prof David Curtis, Honorary Professor, UCL Genetics Institute, said: “While it is true that people diagnosed with schizophrenia are also more likely to be diagnosed with cannabis use disorder, the reasons for this association are far from clear and it is extremely difficult to interpret results such as these with confidence. I am struck by two simple findings. In Denmark, the incidence in schizophrenia in 2016 was about the same as it had been in 1996 but over the same period of time the prevalence of cannabis use disorder increased nearly five-fold. If, as the authors suggest, cannabis use disorder can cause schizophrenia then there should have been a quite dramatic increase in schizophrenia incidence and we simply do not see that. So far as I can see, this study does not really provide support for the hypothesis that cannabis use causes schizophrenia. In fact, it seems to provide evidence that it does not.”
