The Viral Story About the Cop Who Overdosed by Touching Fentanyl Is Nonsense (Slate Magazine, Dr. Jeremy Faust)
"If Green's story is true, it would be the first reported case of an overdose caused solely by unintentional skin contact with an opioid. There is one published case of a veterinarian who was squirted in the eye with carfentanil after trying to sedate an elk (the vet experienced drowsiness, which resolved shortly after receiving a whopping dose of the antidote naltrexone). But scrutinizing Green's story from a medical perspective reveals an irresolvable conflict between the accounts that have been widely disseminated and the realities of medicine and toxicologic possibility."
Discussions of synthetic opioids get people really riled up, but passion is not a legitimate substitute for accurate information. The popular story about the cop who overdosed is wrong, and the details are interesting. If you want to know why, Dr. Jeremy Faust's article in Slate does an excellent job of presenting the science.
