The first responders on the front line in the battle against the national opioid epidemic got a new guideline Tuesday from the Drug Enforcement Agency on how handle the incredibly deadly drug fentanyl. It's called “Fentanyl: A Brief Guide for First Responders.” And Acting DEA chief Chuck Rosenberg said it should be required reading. It was produced thanks to Patrolman Chris Green of the East Liverpool (Ohio) Police Department, as well as officers in New Jersey, Connecticut, Maryland and Georgia who were inadvertently exposed to the extremely dangerous drug and survived.
