A protester smokes marijuana during a demonstration against new government legislation calling for the creation of a "weed pass" and the stopping of the substance's sale to foreigners, in Amsterdam, on April 20, 2012. Several hundred pro-cannabis demonstrators lit up joints in central Amsterdam today in the most public display yet against the Dutch government's plan to stop the drug's sale to tourists. Pot-friendly protesters "flash-mobbed" in front of the capital's Muziektheater -- a venue announced only an hour before on social media sites -- where they played loud reggae music and unfolded banners before lighting up.
