A total prohibition state nestled among a number of other total prohibition states, Tennessee is nevertheless a crossroads for U.S. marijuana traffickers. Indeed, today’s bust at the Nashville International Airport is the second there this month. But the 21 pounds of cannabis a police K9 unit discovered in two suitcases pales in comparison to the 160 pounds police dogs found in four suitcases two weeks ago.

Since at least 2017, police departments around the U.S. have been phasing out their use of drug-sniffing dogs to detect cannabis.
