A subset of people who take psychedelics and then experience flashbacks develop hallucinogen persisting perception disorder (HPPD), a rare condition in which people experience regular or near-constant psychedelic symptoms.

But that’s not all. Some people have a first episode of psychosis (UptoDate article) after a hallucinogen trip or heavy cannabis use and go on to have a persistent or relapsing psychotic disorder (Wikipedia entry on “psychosis”). The verdict is out on whether it is “caused” by the drug use (whatever that means) or if it was an “accident waiting to happen” with any of a number of provocative influences. And, finally, some hallucinogen or stimulant users go on to develop epilepsy, particularly temporal lobe epilepsy (TLE; Wikipedia entry on “temporal lobe epilepsy”), a seizure disorder whose bewildering variety of symptoms can look like psychotic presentations (Google).
