<p>Campus</a> Locks Down For Pot-Smoking 'Holiday' - Education News Story - WNBC | New York</p>
<p>ANTA CRUZ, Calif. -- The University of California-Santa Cruz campus was in lockdown Friday night, but it's not in the traditional sense of the word.</p>
<p>The university is anticipating thousands of students Sunday, gathering to mark the so-called "4/20" cannabis culture holiday, reported KSBW-TV in Monterey, Calif.</p>
<p>Four-twenty is named for the day, which is Sunday's date, or the time of the day well known among regular marijuana users for smoking pot.</p>
<p>It was once a student-only gathering to smoke marijuana at the university's Porter Meadow, but in recent years the crowds have become unmanageable.</p>
<p>UCSC sent thousands of e-mails to students reminding them that it does not condone the 4/20 gathering.</p>
<p>The e-mail also warned that using marijuana could land students a police citation and a campus judicial write-up.</p>
