These mystical experiences are part of the outcome, not an environmental variable. There maybe anecdotal or some other kind of evidence in the sense of what the effect of the supporting environment is on the long term.
this thread is all about the “trip” ie the mystical experience aspect, that presumably the “plasticity-specific” novel psychedeloids do not occasion because they are not considered part of the physiological outcome but merely a drug experience. that is what the comment I replied was countering: GP claimed more study was needed to say the trip IS the treatment, and I’m saying the research has been done.
