From the Introduction: "Abuse of synthetic opioids is devastating communities, endangering public health, and overwhelming the response professionals who protect American communities. Between 2019 and 2020, U.S. drug overdose deaths reached the highest number ever recorded, with synthetic opioids, like illicit fentanyl, largely responsible.  While understanding of synthetic opioids has grown exponentially, important knowledge gaps impact our ability to make informed operational recommendations and decisions across a range of topics, from deploying effective personal protective and detection equipment to developing safe and effective decontamination protocols."
