Summary
Language patterns shift noticeably after psychedelic experiences. Analysis of participants' speech before and after guided psychedelic sessions revealed more positive emotional expression, increased use of words about insight and connection, and fewer references to anxiety. These changes in verbal communication strongly correlated with reported improvements in mental wellbeing.
