Hallucinogen persisting perception disorder: What do we know after 50 years?

Some users suffer from hallucinogen persisting perception disorder, although this is uncommon.

MDMA use has been occasionally associated with liver damage, excessive wear of teeth, and (very rarely) hallucinogen persisting perception disorder.

In addition to concerns about neurotoxicity, several published reports have described hallucinogen persisting perception disorder in MDMA users.

Hallucinogen persisting perception disorder (HPPD) is another condition which has resulted in the onset of the visual snow following the use of hallucinogenic psychedelic drugs.

Hallucinogen persisting perception disorder (HPPD) is characterized by a continual presence of visual disturbances similar to those generated by psychedelic substances.

The hallucinogen persisting perception disorder (HPPD), also known as post-psychedelic perception disorder, has been observed in patients as long as 26 years after LSD use.

Micropsia can be a symptom of Hallucinogen Persisting Perception Disorder, or HPPD, in which a person can experience hallucinogenic flashbacks long after ingesting a hallucinogen.

This could feasibly alter the function/relationship of various structures, specifically the ventral visual stream, which is a likely cause of the anecdotal reports of hallucinogen persisting perception disorder (HPPD) from such chronic users.

However, hallucinogen persisting perception disorder (HPPD) is a diagnosed condition wherein certain visual effects of drugs persist for a long time, sometimes permanently, although science and medicine have yet to determine what causes the condition.
