University spokesman Bronson Hilliard told the Boulder Daily Camera on Wednesday officials still plan to make sure thousands of pot smokers don't gather on April 20, despite the passage of a statewide measure legalizing marijuana.

The new law bans smoking marijuana in public. Earlier this year, the university closed the campus to visitors and blocked access to a student gathering place.

Every year, marijuana activists across the nation hold pot-smoking protests on April 20 to demand legalization.

The gathering at the University of Colorado in Boulder has become one of the biggest campus protests.
