Looking for a college campus where a majority of students support legalizing marijuana? Search no more.
The University of Colorado -- Boulder takes this year's top slot for colleges with "Reefer Madness" in the Princeton Review's annual rankings.
CU Boulder was host to a clash between students and the administration over its annual 4/20 smoke-out, in which the university used "stinky fish fertilizer" to keep pot smokers off its grassy quad. It also closed the entire campus on April 20, 2012 to visitors in an effort to thwart the popular weed event.
Other top colleges on the Princeton Review list primarily included schools from Oregon, New York and California.
