Women coca growers hold coca leaves during the so-called "National day of coca leaf-chewing" in La Paz, Bolivia, Monday March 12, 2012. Bolivia held a national campaign in defense of chewing the coca leaf, known locally as "acullico," parallel to a request for the legalization of this practice which Bolivia's President Evo Morales will make at a UN meeting in Vienna, Austria.
