Location: Boulder, Colo.

The first state in the nation to legalize marijuana also houses one of the most boisterous party schools, known for a massive marijuana "smoke out" that existed many years before the grass was legal. The University of Colorado at Boulder took the #3 spot in Playboy's ranking of the top schools for revelry in the US. The school's art program "affirms the power of art to transform individuals and society," making it one of the best spots to produce strong work and to ingest chemicals of all stripes, even as the college fights to shed that perception.
