BAKERSFIELD, Calif. (KGET) — The toll from fentanyl, the illicit synthetic opioid that’s sweeping the country, continues to rise.

The Kern County Coroner’s Division reports that local fentanyl deaths are now at 104 this calendar year, putting the county on track for 155 overdose deaths attributed, in whole or in part, to fentanyl. Last year’s death total was 125.

Law enforcement and health officials report that fentanyl — manufactured primarily by Mexico’s Sinaloa cartel — is turning up not only as an unadvertised substitute for heroin, its chemical cousin, but in virtually every street drug. And in many cases, users don’t realize that’s what they’re taking.

Fentanyl deaths are up across the country, resulting in a shortage of the injectable version of Narcan, the opioid overdose antidote drug. That’s according to Pfizer, which manufactures Narcan.
