Cannabis Presentations to the Emergency Department After Motor Vehicle Crashes In the Era of Legalization for Recreational Use
This study examined cannabis and/or alcohol use of drivers involved in motor vehicle crashes (MVCs) who reported using cannabis and/or alcohol within 8 hours of the crash. Data was collected on emergency department (EDs) visits by 817 patients in three states where cannabis use is legal (Denver, Colorado; Portland, Oregon; Sacramento, California). Information included: frequency of alcohol or cannabis use; type of cannabis used; use of cannabis, alcohol, or both; and crash characteristics. Drivers were interviewed and blood and breathalyzer test data was analyzed. It was found that 8% of drivers self-reported cannabis use in the 8 hours before their MVC; however, based on the biosamples, 18% of the drivers were positive for cannabis use in the 8 hours prior to their MVC.
