Why? Are you "volunteering" to be a subject in a study? There would be no real way to prove this one way or another. To do so, one would need a sample of people who consumed psyllocybin mushrooms, and a matched group which didn't, and then track them as they matured.
There would be too many other variables to control, and the "subjects" would tend to get "lost" to follow-up.
