Answering that I found this case for example. "Report of a 15-year-old boy with a possible case of PHPD is provided by Kaminer and Hrecznyj (1991). The subject used LSD on a daily basis for 6 months before admission to an inpatient treatment facility. He admitted constant perceptual disturbances over the previous 6 months, including colored-dot patterns, white trails behind moving objects, halos around objects, "like a television screen with multiple transmission disturbances" (p. 173), and occasional auditory hallucinations consisting of unintelligible whispers.
