LSD and other hallucinogens have long been said to cause flashbacks for some heavy users, but HPPD is a unique phenomenon. Some who suffer from HPPD develop the disorder after years of using hallucinogenic drugs such as LSD and psilocybin mushrooms. On Sunday, one of Locke’s colleagues will present the findings of a recently completed survey titled “Hallucinogen Persisting Perception Disorder (HPPD): When the Trip Doesn’t End” at the annual conference of the American Psychiatric Assn. Some experts believe a bad drug trip can inflict severe trauma that leaves people with a condition akin to PTSD. More than 90% of the people who responded to Locke’s online survey reported that they had taken medication or supplements or undergone other mental heath treatment for their HPPD symptoms.
