Law enforcement agencies across the country are raising alarms about the increasing trend of finding heroin laced with an extremely lethal elephant tranquilizer called carfentanil, The Washington Post reports.
The drug is 10,000 times stronger than morphine and 100 times stronger than fentanyl, just two milligrams of which is lethal—that’s about one toss of a salt shaker. Carfentanil can be absorbed through the skin, and just a puff from re-sealing a plastic bag can be lethal, raising risks for first-responders. Just a whiff can kill a drug-sniffing dog.
Though authorities are struggling to identify it in overdose cases—and sometimes not trying due to the health risks—carfentanil has been linked to dramatic increases in overdoses, which were already at alarming levels amid the nationwide opioid epidemic.
