PORTLAND, Maine - Over the weekend, York police responded to a 24-year-old man who overdosed on elephant tranquilizer.
Sgt. John Lizanecz says carfentanil is the lastest synthetic opioid that's being mixed with heroin, and it's 10,000 more times powerful than morphine.
"If you touch skin-to-skin on this, even a couple of grains - they liken it to granules of salt - can kill you, if it touches your skin, or if you inhale it," Lizanecz says.
Lizanecz says it took six doses of Narcan, the opioid overdose anti-dote, to revive the man, who was treated at a local hospital and released.
