Southern Nevada Health District detects medetomidine in illicit drug supply
he Southern Nevada Health District has identified medetomidine—a veterinary sedative also known as “rhino tranq”—in the local illicit drug supply through its community drug surveillance program, which anonymously samples used drug paraphernalia. While medetomidine use has not been widely reported in Nevada, the Health District has confirmed five positive samples since July 1, 2025, representing less than 1% of all samples collected since September 2024.
