The University of Colorado still plans to make sure thousands of pot smokers don't gather April 20, despite the passage of a statewide measure legalizing marijuana.
Bronson Hilliard, spokesman for the Boulder campus, said the 4/20 smoke-out causes a disruption at CU, which is the heart of the problem.
"A large, 10,000- or 12,000-person, uncontrolled smoke-out on the campus is a huge physical disruption to our operation," he said. "Marijuana, legal or not legal, was never the issue for us. It was an issue of forcing us to accommodate a crowd that large in the academic heart of the campus, while there is teaching and research going on."
Last year, CU took unprecedented steps to snuff the smoke-out -- closing the campus to visitors and entirely shutting down the Norlin Quad, which staged the annual marijuana rally.
