About a third (32.7%) of people reported symptoms of hallucinogen persisting perception disorder (HPPD) four weeks after a real-world psychedelic experience, but only 2.94% found those symptoms distressing. Delusional ideation was slightly higher among those with more lifetime psychedelic use at baseline, yet it decreased significantly four weeks after the experience, suggesting the baseline correlation may not be causal. Younger age, female gender, a personality trait called absorption, less non-psychedelic substance use in the prior six months, and using psychedelics outside a retreat setting predicted HPPD-like symptoms. The findings are limited by the observational design.
