BOULDER, Colo. -

A provocative anti-marijuana campaign aimed at Colorado youths has angered marijuana activists for its tag line, "Don't Be a Lab Rat."

Now a school system is declining to display a human-size cage used in the campaign.

The Daily Camera reports that the Boulder Valley School District has announced it won't participate in the campaign. School officials say they don't believe the cage is an effective display for 12- to 15-year-olds about the dangers of using marijuana. Instead, the cage will be displayed near a city park through Sept. 15.

The cage attracted vandalism and jeering social media pictures during its stint in Denver.

But the state health department says its campaign is at least getting people talking. The campaign is funded by marijuana taxes.
