So long as there continues to be a large unmet demand for opioids because we aren't treating people with addiction, the illicit market will find ways to meet that demand - Hakique Virani MD

Carfentanil is the most potent commercial opioid in the world, according to the U.S. Drug Enforcement Agency. It is 10,000 times stronger than morphine, and at least 100 times more powerful than its analog, the opioid fentanyl, which was linked to Prince's untimely death. Carfentanil's only officially recognized use is to sedate large zoo animals like moose, buffalo and elephants. It takes just two milligrams of Carfentanil to knock out a 2,000-pound African elephant, and the veterinarians who administer the drug use gloves and face masks to prevent exposure to it, because a dose the size of a grain of salt could kill a person – and may be lethal even when absorbed through the skin.
