State officials collected additional samples containing medetomidine the following month that were involved in two non\u00adfatal overdoses.\u00a0<\/p>\n<p>Officials then alerted medical examiners about the presence of medeto\u00admidine in the illicit drug supply, which helped establish a drug standard and development of a postmortem tox\u00adicology test. Systematic postmortem toxicology testing for medetomidine began in October 2024 in New York City.<\/p>\n<p>After months of laboratory detection in less than 10% of opioid samples, medetomidine skyrocketed in the illicit drug supply, with a jump to over 20% of collected opi\u00adoid samples by October 2024 and into 2025. From May 2024 through December 2025, 25.1% of total included opioid samples contained medetomidine, with a monthly peak of 44.1% of samples in May 2025.<\/p>\n<p>Death certificate data in New York City revealed medetomidine as a contributing cause of 18 overdose deaths in 2024 but 134 such deaths in 2025.
