This is not true. I’m sure it’s true for microdosing but you can have a serious adverse event to a larger dose of mushrooms! From serotonin syndrome to full blown psychosis that can lead to dangerous behaviour! This happened to my husband and he actually KILLED his dear friend while hallucinating that they were a murderer and terrorist trying to kill him.
Psychedelics are powerful medicine but you must be careful when telling people there are no risks. There are absolutely risks.
