Not that it's easy to tell from the police reports. During the Labor Day crackdown, there were more than 1,320 DUI arrests -- one of the drunk driver who crashed into a car carrying cannabis activist Jenny Kush, who was killed in the collision. But while law-enforcement sent tallies of their arrests to CDOT, they did not distinguish between arrests for driving under the influence of alcohol and drugs.
And despite the brave new world of recreational retail marijuana sales, there are no changes to how the New Year's crackdown arrests will be reported. "It's still a challenge for us to differentiate between the two," says CDOT's Emily Wilfong. "People don't understand the challenges."
William Breathes does: After writing about the death of Jenny Kush, he tried to discover how many of the Labor Day DUI arrests were for driving under the influence of marijuana. Read the results of his labor in "Under the Influence."
"It would probably take legislation" to require more specific statistics on marijuana-impaired driving, Wilfong suggests. But in the meantime, the heat is definitely on New Year's Eve.
