"In 2021, the Drug Abuse Warning Network (DAWN) identified 141,529 (unweighted) drug-related emergency department (ED) visits from 52 participating hospitals. These data were analyzed to (1) generate nationally representative weighted estimates for the top five drugs in drug-related ED visits, (2) assess monthly trends and drugs involved in polysubstance ED visits in a subset of sentinel hospitals, and (3) identify drugs new to DAWN's Drug Reference Vocabulary (DRV) in 2021."
