The section on conspiracy thinking was interesting to me. I've been trying to understand the ever increasing amount of it in our society, and my thoughts keep going back to the rise in marijuana legalization. I can't help but feel that there is a link.
Like ketamine, other psychedelics can trigger mild psychosis and with it conspiratorial thinking, grandiosity, and all of the other symptoms described here.
The rise in legalization seems, anecdotally, to match the "normalization" of tin-foil hat thinking in society. Years ago Dan Quayle was essentially disqualified from office for misspelling potato, now Marjorie Taylor Greene publicly decries the Jewish Space Lasers and nobody blinks. I feel like there has to be more to societies changes over the last ~25 years than "the internet".
