TZD Traffic Safety Hotdish: Cannabis and the Highway through the Lens of EMS, Law Enforcement, and Prosecution

Wednesday, April 12, 2023

About the Event

This webinar included information about the impairing effects of cannabis and how it impacts a person’s ability to drive. It also explored public perception of cannabis use and driving, examined existing laws related to cannabis and driving, and discussed the highway safety considerations of the current cannabis legalization bill that is making its way through the legislature in Minnesota. Additionally, presenters shared data from the state's emergency medical system that can help identify any trends in pre-hospital care since changes were made to the state’s laws on THC edibles.
