Guerras Ajenas (2016) Wars of Others, a new original documentary by HBO Latin America, will premiere on June 13th, at 8:00pm exclusively on HBO. The documentary examines the practice of aerial spraying with glyphosate, an herbicide declared to be potentially carcinogenic by the World Health Organization in 2015. The aerial fumigation has been a key tool in the collaboration between Colombia and the United States in the overall "War on Drugs", and specifically against the cultivation of the coca leaf. Thus, for many years Colombia had been the only country in the world to disperse this herbicide from airplanes, making way for bitter debates between those that defended it as a harmless product and those that argued that it was severely affecting the health of Colombians.
