you would be wrong. if you are predisposed to psychosis shrooms can trigger that.
I get it that you prefer mushrooms. But most people actually handle LSD better than mushrooms. So the fact you trashed LSD is a little silly.
On the other hand, there are increasing numbers of recent studies that refute the idea that psilocybin is as dangerous as some people have claimed in the past [1] [2]:
> We failed to find any associations between lifetime use of psychedelics and past year serious psychological distress, receiving or needing mental health treatment, depression, anxiety, or suicidal thoughts or behavior in the past year. Rather, lifetime use of psychedelics was associated with decreased inpatient psychiatric treatment.
I'm unable to find any studies showing a link between psilocybin and the triggering of latent mental illness. There's some debate about whether age is possibly not coincidental, in the sense that the heaviest users of "hard" psychedelics like LSD tend to start at an age which coincides with the emergence of latent disorders such as schizophrenia, implying that there isn't necessarily a cause and effect.
Nobody is obviously promoting irresponsible use of psychedelics. That said, everything in life has risk. The risks involved with psilocybin seem infinitesimally small compared to those of, say, alcohol or smoking.

And I've seen people have psychosis manifest on mushrooms that was life altering, lasted for months, and they were never the same.
