Cops in Colorado have been trained on how to spot drivers who are high, and many people have predicted a surge in DUI arrests due to the legalization of marijuana, but at least in Northern Colorado it hasn't really happened. 

Either the police are recognizing high drivers, or drivers aren't high...

Last weekend, several Colorado law enforcement agencies joined forces to set up a sobriety checkpoint in Larimer County, which, by the end of the night, produced 22 arrests. 21 of them for alcohol, and one for possession of marijuana and paraphernalia by a minor. Not a single arrest was made for stoned driving.

1,572 vehicles were stopped over the weekend, and although it may not be fair to assume that this is an accurate portrayal of the exact ratio between drunk and stoned driving in Colorado, it does provide fascinating stats. Especially because the Colorado Department of Transportation (CDOT) has a budget allocating roughly $500,000 for their “Drive High, Get a DUI” ad campaign, while only allotting $325,000 for ads for drinking and driving.

Are the ads working? Or are stoners smarter than drinkers?
