Phencyclidine is a synthetic dissociative anesthetic used medically in the past and known illicitly as a hallucinogen. It is pronounced with a four-syllable pattern and a stress peak on the third syllable, yielding a distinct cl-uh-sihd-lin-ide rhythm. In modern usage, it appears mainly in academic, pharmacology, and forensic contexts, though it is a controlled substance with historical relevance in medicine and substance abuse discussions.
