We are living in the golden age of cocaine. Consumption and production have never been higher, despite more than 50 years of the War on Drugs. For many Europeans and North Americans, cocaine is a party drug; for many Latin Americans, it is a source of bloodshed, violence, corruption and death. Sangre Blanca by award-winning documentary photographer Mads Nissen delves into the murky depths of the cocaine trade, examining the human consequences along its journey—from the neglected countryside of Colombia, to the cartel lands of Mexico, to craving consumers on a European dancefloor. The most significant exploration through photojournalism of the cocaine industry published to date, it follows the white powder across continents, exposing an uneasy link between Western pleasure and Latin American violence. 'The War on Drugs has been raging for more than 50 years. I wanted to question whether it is working—and if so, for whom.' For Nissen, photography is all about empathy: creating understanding and intimacy while confronting contemporary social issues such as inequality, human rights violations and the lack of global responsibility.
