Amnesty boxes are going up at the Colorado Springs Airport on Wednesday for people who didn't realize that it's illegal to possess marijuana on a plane.
It is legal to leave marijuana in a parked car at airports under the Colorado law that legalized recreational marijuana, but you can't bring marijuana inside airport facilities.
Officials are encouraging people to leave their marijuana behind, but they also want to help people who broke the law and don't want to miss their flights. Installation of the boxes begins Wednesday.
Colorado Springs police chief Pete Carey said last week that all checked bags are screened by Transportation Security Administration, the U.S. Department of Homeland Security agency that screens airline passengers and baggage for weapons and other contraband.
If passengers pack the pot and TSA officials find it, they will call Colorado Springs police, Carey said.
Passengers will have the opportunity to give up the pot without penalty, he said. All the marijuana placed in the special amnesty boxes will then be destroyed.
But once the doors on an aircraft are closed, the passengers are under federal law, Carey said. And, if they get caught with weed they can be fined and jailed, he said.
Denver International Airport also has banned marijuana on DIA property, and enforcement is expected to begin this month.
