Colombia will use drones to destroy coca crops as it grapples with record cocaine production

Colombia will use drones to resume spraying of coca crops with a weed killer, the government announced on Monday as authorities grapple with record levels of cocaine production that have fueled tensions with the Trump administration. The South American country banned aerial fumigation of coca crops in 2015, after the World Health Organization put glyphosate — the weed killer used by spray planes — on a list of carcinogens.
