Chemical Countermeasures Research Program Initiative: Basic Research on The Deleterious Effects of Acute Exposure to Ultra-Potent Synthetic Opioids (R01 – Clinical Trial Not Allowed)

This opportunity will support research towards understanding and mitigating the deleterious effects of acute exposure to Ultra-Potent Synthetic opioids (e.g., fentanyl, carfentanil, nitazenes) and their combinations (e.g., fentanyl and xylazine).
