> The effects of LSD resemble schizophrenia so closely, in fact, that it has led to studies on rats using LSD as a hypothetical model to represent schizophrenia. In other words, we give rats LSD and see what chemicals reduce the effects to find treatments for schizophrenia.

And that was the research which led to the rejection of LSD as a model for schizophrenia, and there is still no evidence tying LSD to schizophrenia as all the correlations are heavily contaminated by polydrug use.

It's messy, but https://en.wikipedia.org/wiki/LSD_and_schizophrenia is a better overview of the topic...
