Hallucinogen persisting perception disorder (HPPD) typically follows use of classical hallucinogens like LSD or psilocybin, but its cause is unclear. This case report describes a boy who developed HPPD-like symptoms after using cannabis only seven times, suggesting that cannabis may also trigger the disorder. The authors present this case to highlight the possibility of HPPD occurring with cannabis use alone.
