Maine’s Congressional delegation has asked the US Drug Enforcement Administration (DEA) to clarify federal guidance that could potentially result in new costs for Maine emergency medical services (EMS) agencies. In a letter sent to DEA Administrator Terrance Cole, all four members of Maine’s delegation explained the confusion that currently exists surrounding the agency’s implementation of a 2017 law. Under the Controlled Substances Act (CSA), along with related DEA regulations, any practice that dispenses controlled substances must register with the government. “Therefore, swift clarification from the DEA is urgently needed not only to prevent exorbitant, unexpected costs from being forced onto Maine’s EMS agencies but also to preserve vital local partnerships.” “Therefore, we ask DEA to issue clarifying guidance as soon as possible to prevent further confusion and to ensure more unnecessary costs are not borne by our EMS agencies,” they concluded.
