Risk of fatal traffic crash higher during annual 4/20 cannabis celebration

(University of British Columbia) US drivers are more likely to be in a fatal traffic crash during the annual April 20 cannabis celebration. Twenty-five years' worth of data from the National Highway Traffic Safety Administration shows the number of drivers involved in fatal crashes after 4:20 pm on April 20 is higher compared to the same time intervals on control days one week earlier and one week later.
