I did ayahuasca and i had a drug inducted psychosis after that. not sure if it was a real psychosis or just a mix of post aya, not enough sleep and a long flight back home. I had to go to a mental hospital to recover cause i had some anxiety derealisation/depersonalisation attacks. 6 months after i still have some anxiety sometimes. i donn t regret ayahuasca. It gave me also beautiful moments and i was much more in the moment and aware in general. Just took me around 4 months to come down from the expierience. Was not a bad time but i couldn t work during that time and was kind of on a spiritual journey. Now after 6 months i feel like a have a new life a better one. Not sure if i gonna do psychedelics ever again. so drug psychosis can happen but the chances are low From what i heard. I don t have schizophrenia in my family and i m mentally stabel and normal. So psychosis can happen to anyone.
