National Weed Day, 420, Stoners Day, 4:20, National Smoke Day, and 4/20 are all terms used for what is known as a holiday for pot smokers. How fitting that Bob Marley fans will be able to watch Kevin MacDonald's documentary, 'MARLEY', streaming on Facebook on the same day that many will unite to celebrate their affection for marijuana on April 20, 2012. Facebook users who want to watch "MARLEY" can watch the documentary for free on the Bob Marley Facebook page starting at 12:01 am on Friday, April 20.

Of course it does haha
