#DrivingWhileImpaired

It’s always nice to get a break from the endless stream of industry marketing materials about electrification, though this week’s impromptu theme still involves going green. Following news that General Motors is considering changing its drug testing policies to exclude marijuana, there has been heavy coverage of an Insurance Institute for Highway Safety (IIHS) study claiming states that have legalized recreational use of cannabis are seeing more crashes.

But the framing seems wildly irresponsible as it fails to highlight the problem being heavily tied to individuals operating a vehicle under the influence of marijuana and alcohol combined. It’s more or less what the IIHS attempted to do in 2018 with help from the Highway Loss Data Institute (HLDI). Our guess is that the duo is seeking out fresh reasons for insurance companies to raise rates in regions that have legalized pot because even their own research complicates the issue.
