April 29, 2014: 4:20 in Vancouver - Amanda Siebert

VANCOUVER – Two attendees at the city’s annual 4:20 event, held every year on April 20 outside the Vancouver Art Gallery, set up a gas mask for smoking marijuana. The event, which has occurred in Vancouver every since 1995, drew nearly 30,000 pot enthusiasts. Though held over the course of a single day, Vancouver’s 4:20 event is the world’s largest free marijuana market: vendors and buyers alike are not fined or penalized by the police department and can smoke and sell openly.
