>>13714634Source? Most antipsychotic drugs work primarily by inhibiting dopaminergic pathways, whilst classical psychedelics work via a serotonergic mechanism. The "drug induced psychosis" is not typically the psychosis of a mental disorder w/r/t psychedelics, while stimulant psychoses exhibit extremely similar pathologies to "typical" psychotic episodes because their action mechanisms are also dopaminergic.
There is a serotonergic component to antipsychotics as well, which is why you can use drugs like risperdal or quetiapine to kill trips, because they have an inverse agonist or antagonistic mechanism for the 5-HT receptors that psychedelics work on, that exists alongside the dopaminergic mechanism.
In addition, the rise of first-occurring psychotic episodes related to drug use seem to be congruent with the idea of a stressful event being trigger for a latent mental illness, rather than a mechanism by the drug itself. This is supported by a recent survey in what I think was Denmark, that showed no significant correlation between drug use and mental illness, implying that drug use only exacerbates rather than causes mental illness.
I'm pretty certain that there are also reports about "real" or non-drug-related psychoses being qualitatively different from typical psychoses. Schizophrenics don't usually rave on about pretty colors and shapes, only voices in their head, which afaik isn't typical of a psychedelic experience.
It just seems indeterminate at best right now whether or not drug use can actually "cause" mental illness. I'll grant it can turn you into a fucking nutcase though, given all of the intelligent people that take psychedelics and start to believe the hallucinations too much, but I have some trouble characterizing this as a typical "mental illness".
