The hallucinogen-induced persistent perception disorder (hppd) is a disturbing complication resulting from the use of hallucinogens. We report on a case-study in which an artist suffering from visual, auditory and olfactory hallucinations also experienced chromatic-phonemic synesthesias that had persisted for two years after he had stopped using lysergic acid diethylamide (lsd). The case described demonstrates that individuals suffering from hppd can also experience synesthesias that may in fact differ phenomenologically from 'coloured hearing', which is a symptom known to occur in the context of substance abuse.
致幻剂所致持续性感知障碍（HPPD）是使用致幻剂引起的一种令人不安的并发症。我们报告了一个案例研究，一名患有视觉、听觉和嗅觉幻觉的艺术家，在停止使用麦角酸二乙酰胺（LSD）两年后，仍持续经历色-音联觉。所描述的案例表明，患有HPPD的个体也可能经历联觉，事实上，这种联觉在现象学上可能与“彩色听觉”不同，“彩色听觉”是已知在药物滥用情况下出现的一种症状。
