||There are no known long-term effects of psilocybin mushrooms. Psychoactive mushrooms have been used for thousands of years by several cultures and there are no recorded long-term adverse health effects related to their use.|
There are rumors about pretty much all psychedelic drugs causing reproductive harm...nearly all of these are false. It is a common scare tactic used to dissuade people from experimenting. This is a completely separate issue from whether or not use during pregnancy can affect the fetus, but in the case of mushrooms there is little evidence that even that is a problem.
Hope this helps.
