Youth Subcultures: "420"

For people who advocate for the legalization of non-medical cannabis, April 20th (4/20) has been an important date for quite some time now.  People gather in places around the world (mainly college campuses) to smoke pot on this date, at 4:20 in the afternoon.  The term "420" has actually evolved beyond just a date and a time; it is now used to describe this particular subculture.  Youth who say that they are "420" are saying that they are avid cannabis users and implying that they are also advocates for legalizing the substance.
