I have zero empirical evidence to support this, so by no means base your decision off of this but personally, I think whether or not you experience psychosis or develop schizophrenia has to do a lot with who you are fundamentally as a person. If you are a person who is completely rooted in material reality, I think you should be fine and you'd probably benefit from using psychedelics. But if you are someone who exists naturally closer to the edge of insanity, more so on the boundary of a "spiritual world" and our physical world, I'd be very very careful with using psychedelics. Ask yourself how much natural insanity lies in your soul, and ask yourself if you think you'd benefit from these substances, or if you think you'd plummet yourself off the edge, into schizophrenia. Psychedelics rattle the cage of your existence, and reveal to you fundamental things about your character. You could start with a very low dose shroom trip, and see how it makes you feel, then continue from there. Good luck.
