Hallucinogen persisting perception disorder (HPPD) is a non-psychotic disorder in which a person experiences apparent lasting or persistent visual hallucinations or perceptual distortions after using drugs, [1] including but not limited to psychedelics, dissociatives, entactogens, tetrahydrocannabinol (THC), and SSRIs.
Additionally, it may trigger "flashbacks," also known as hallucinogen persisting perception disorder (HPPD), where individuals experience persistent visual distortions after use. [17] [18] The effects of LSD begin within 30 minutes of ingestion and can last up to 20 hours, with most trips averaging 8–12 hours.
HPPD is most common after LSD ingestion, but can occur after any hallucinogen use. HPPD is commonly described in psychiatric literature and illusory palinopsia symptoms are sometimes not defined as palinopsia. It is not clear if there is a relationship between HPPD and the quantity and strength of hallucinogen doses taken. [4] [18]

From the late 1940s through the mid-1970s, extensive research and testing was conducted on LSD. During a 15-year period beginning in 1950, research on LSD and other hallucinogens generated over 1,000 scientific papers, several dozen books, and six international conferences. Overall, LSD was prescribed as treatment to over 40,000 patients.
