Medetomidine Emerges as New Threat in North Carolina Street Drug Supply, Raising Public Health Concerns
Medetomidine, a potent veterinary tranquilizer, has significantly increased its presence in North Carolina's illicit street drug supply, surpassing xylazine in prevalence, according to data from the UNC Street Drug Analysis Lab. This development follows a trend of constantly changing adulterants in illegal drugs, making it difficult for users to know what substances they are consuming. The North Carolina Department of Health and Human Services issued a provider alert on June 8, flagging medetomidine and other emerging substances. Unlike xylazine, medetomidine does not typically cause skin wounds but is considerably more potent, leading to prolonged sedation, slowed heart rate, low blood pressure, and severe withdrawal symptoms that can require intensive care unit hospitalization. Medetomidine is frequently mixed with fentanyl, complicating overdose responses as naloxone, while effective for opioids, does not reverse the tranquilizer's effects.
