Video: Marijuana Protests In San Francisco

Yesterday was April 20th – or 4/20 – a kind of national holiday for marijuana advocates. As CBSNews.com's Brian Montopoli reported here, the day was celebrated with protests, calls for marijuana legalization and pot-themed parties.

"There's some data out there that shows 47 percent of Americans have smoked marijuana at some point in their life," Keith Stroup, founder of the marijuana legalization organization NORML, said in the story. "That was five years ago, and that means there are likely more living Americans today who have smoked than have not. That tells me that we are very close to a tipping point on this issue."

Last night, CBS 5 in Northern California also took a look at the issue and the large protest held at San Francisco's Golden Gate Park. You can watch their report below:
