Colorado wants to know why some marijuana users choose to drive while stoned

As it continues to combat stoned driving in Colorado, the state transportation department is hoping to have an online conversation with the public about their opinions toward marijuana, alcohol and driving.

The Colorado Department of Transportation has launched The Cannabis Conversation, an online, anonymous survey that asks people about their marijuana and alcohol use and how they feel about driving while using marijuana. The survey can be found at

“We want to find out from marijuana users why they drive high when it’s so dangerous,” said Sam Cole, a transportation department spokesman.

In 2016, there were 77 traffic fatalities involving drivers with active THC in their blood, according to CDOT statistics. In Colorado, a driver is presumed impaired when when they have five nanograms or more of Delta 9-THC in their blood, but Colorado police do not use roadside devices to detect marijuana. Arrests are based on observed impairment.
