A man smokes marijuana as thousands of people gathered at 4/20 celebrations on April 20, 2016 at Sunset Beach in Vancouver, Canada. The Vancouver 4/20 event is the largest free protest festival in the city, with day-long music, public speakers and the world's only open-air public cannabis farmer's market where people sell all kinds of cannabis and extracts while educating the crowd about medical marijuana, political involvement and activism. Canadian Federal Health Minister Jane Philpott says Canada will roll out the legislation in the spring of 2017 to begin the process of legalizing and regulating marijuana.
