To curb drug use, these police officers have turned to what they know best: doughnuts.

Iowa State University and Ames police departments launched a campaign to encourage students not to smoke weed by giving out free glazed doughnuts.

The police departments busted out a “Donutmobile” emblazoned with “Donut Disrespect” on the hood Thursday at the campus in Ames, Iowa.

“Donutmobile will be out soon. Donut come baked (or fried),” Ames Police Department wrote on Twitter.

Using hashtags such as “#GlazeItDontBlazeIt,” the department also got the word out on social media.

In a viral video on Twitter, the officers promise donuts to anyone who “donut disrespect, donut discriminate, donut harass and donut hate.”

“Respect each other, and donut make bad decisions and we will give you free donuts,” Iowa State University police officer Anthony Greiter said.
