Psychosis valuable? The difference between clinical psychosis and a psychedelic breakthrough experience is that the latter is integrated. The Psychonaut finds a way to make it part of his psyche and thus neutralize the dissonance.
Those who talk about predisposition really have no clue regarding proper psychedelic use. Psychosis is the whole point. But, taking place inside a framework that allows for integration. There is a reason shamans have rituals.
But if that's true, replace "psychosis" in the preceding arguments about the dangers with "failure to integrate the experience".
Same danger, different name.
It still needs to be acknowledged, not brushed away. Frameworks and rituals do not remove this danger. They may alter the risks, but it still occurs within them.
Its predictable:
Have a bad experience?
“Whaat no way dude, you must have taken something else or you were predisposed to schizophrenia you should have predicted that and checked your family history and genetics first! This experience is totally invalid to us and anyone considering using our favorite psychadelic”
Develop schizophrenia?
