Happy 4/20, the unofficial holiday celebrating marijuana!

These are good times to be a pothead” writes Los Angeles blog LA Observed. “Let's Be Blunt: It's Time to End the Drug War” argues Forbes.

Just how many people celebrate 420 anyway? The Washington Post estimates at least 14.7 million people smoke weed in the United States (2010 numbers), so we’re banking the answer is “a lot.”  

As you ready your pipe, bong, bowl or whatever apparatus you have at hand for weed smoking (not that we'd condone such an act) enjoy these videos celebrating the act of toking.

Check out this YouTube video of student celebrations at the University of Colorodo Boulder in 2010. Estimates put the crowd size at more than 10,000. (Parents, avert your eyes, unless you're in the crowd.)
