Comparing triggers to visual disturbances among individuals with positive vs negative experiences of hallucinogen-persisting perception disorder (HPPD) following LSD use.

CONCLUSIONS: HPPD I and II differ in terms of visual disturbances and triggers, possibly representing different phenomena existing on the same spectrum. SCIENTIFIC SIGNIFICANCE: Our study indicating differences in triggers to HPPD I and II adds to existing literature on differences in visual disturbances between the two subtypes. Further research elucidating additional differences between the subtypes of HPPD is needed. (Am J Addict 2017;XX:1-4). PMID: 28654720 [PubMed - as supplied by publisher]
