I’d never heard of 4/20 until I moved here, but it seems to be a pretty established day of toking celebration on this side of the Atlantic. The story of its origins are great– a bunch of high school guys in the 70s met at 4.20 every day after school to go hunting for a mythical marijuana field. The term 4.20 became synonymous, amongst their gang, for getting baked.  They happened to hang out with the Grateful Dead, so the term has spread amongst the toking community. Now 4/20 is a day to celebrate the weed. Tony Newman  of the DPA also wants stoners to take a moment today to recognize the political context of  their use.
