In 20 years of grinding war in Afghanistan, the United States dropped a multitude of weapons from the skies: Millions of tons of ordnance. Hellfire missiles launched from Predator drones. Even the “Mother of All Bombs,” the most powerful nonnuclear bomb in existence. And, amid the more conventional projectiles, tiny poppy seeds. By the billions.
On and off for over a decade, the Central Intelligence Agency conducted an audacious highly classified program to covertly manipulate Afghanistan’s lucrative poppy crop, blanketing Afghan farmers’ fields with specially modified seeds that germinated plants containing almost none of the chemicals that are refined into heroin, The Washington Post has learned.
The covert program, which has not previously been disclosed, is an unreported chapter in the 2001-2021 U.S. war in Afghanistan and in the long checkered history of American efforts to combat narcotics globally, from Latin America to Asia. Its existence was confirmed by 14 people familiar with aspects of the secret operation, all of whom spoke on the condition of anonymity to describe a classified project.


The program’s disclosure comes as the war on narcotics is again dominating the security agenda. President Donald Trump has declared war on drug cartels in the Western Hemisphere, ordering more than a dozen lethal strikes on alleged drug boats in the Caribbean and the eastern Pacific, designating cartels as terrorist groups, and moving a vast naval and air force to the region. He has also authorized the CIA to take aggressive covert action against drug traffickers and their supporters.
This latest effort, like the fight against opium in Afghanistan two decades ago, faces uncertain success, according to former officials who participated in drug wars of the past.
In Afghanistan in the early 2000s, the burgeoning opium trade was thwarting U.S. goals, as American troops engaged in a deadly struggle to defeat the Taliban, eliminate terrorist groups and stabilize the weak Western-backed government. Afghan heroin fueled corruption in President Hamid Karzai’s government and in the provinces. It helped pay for the Taliban’s weapons and equipment. And it accounted for the majority of global heroin supplies, with most of the drugs bound for Europe or the former Soviet Union.
Western allies and U.S. government agencies argued bitterly over which strategies would dent the crop without undermining rural Afghan support for Karzai. Diplomats and drug enforcement officials debated everything from aerial herbicide spraying to purchasing the entire Afghan crop and sending it overseas to be processed into medicine.
Unbeknownst to almost all of them, the CIA was operating its own secret heroin-eradication program, run by the spy agency’s Crime and Narcotics Center, which was flush with funds during the Afghan war. The airdrops of modified poppy seeds began in the autumn of 2004, three people familiar with the program said. The operation was paused at least once and ended about 2015, those familiar with it said.
