The Research Brief is a short take about interesting academic work.
The big idea
Long before Pablo Escobar's Medellin cartel got rich supplying Americans with cocaine in the 1980s, Colombia was already the United States' main source of illicit drugs - specifically, marijuana. That's the takeaway of my new book "Marijuana Boom."
Back in the 1970s, peasant farmers from the Sierra Nevada de Santa Marta - a remote and mountainous region of Colombia's Caribbean coast - began shifting from banana, cotton and coffee production to marijuana cultivation. When this population again pivoted to growing coca leaf for processing into cocaine in the 1980s, they set Colombia on a course to become the illicit drug capital of the Americas.
Why it matters
This research upends other old tropes about the drug trade, including the idea that it's inherently violent.
Colombia's marijuana economy operated relatively peacefully until the Colombian and U.S. governments in 1978 launched a militarized campaign to eradicate marijuana crops and increase drug interdictions. Traffickers retaliated, giving rise to the now familiar "war on drugs"-style dynamic of escalating conflict.
My research also disproves the long-held academic consensus that illegal drug markets emerge in remote areas where the state has insufficient presence.
I find Colombia's marijuana boom was actually an unintended consequence of state-led efforts to economically develop Colombia. Throughout the 20th century, Colombia worked to build its banana export sector, create a cotton belt to supply Colombian textile factories and to redistribute land. By the 1970s, Colombia was expanding international trade, particularly with the U.S.
These changes made some rural Colombians rich but, my research shows, impoverished peasant farmers in the Sierra Nevada de Santa Marta. People who'd grown legal commodity crops saw opportunity in exporting an illegal one to the United States: marijuana.
My book recounts how and why people in northern Colombia used their farming experience to grow and export marijuana. But it doesn't detail their next transition, from marijuana to cocaine.
In southern Colombia, academics have documented how Pablo Escobar's generation of traffickers financed new settlers to grow coca leaf, the base ingredient in cocaine, in the 1980s. We just don't know how cocaine simultaneously supplanted marijuana as the staple drug crop of the peasant economy up north.
How I do my work
This began as a personal quest to understand the country of my childhood. My father is from the Sierra Nevada de Santa Marta, where marijuana once boomed.
Some of my research was archival, conducted in Colombia and the U.S. But much of it was done on the ground. I began collecting testimonials in northern Colombia is the early 2000s, during Colombia's 52-year armed conflict. Paramilitary forces controlled the area. The war ended in 2016. But armed groups, including cartels, still operate there.

To stay safe while studying an industry that uses cash and violence to keep its affairs clandestine, I relied on friends and family, who helped me establish contacts and identify information sources. I also kept my questions focused on the defunct marijuana business - not the active cocaine trade.
This focus helped me avoid reproducing what historian Luis Astorga calls "the mythology of the narcotrafficker." There are no Pablo Escobars in my book - just everyday Colombians who seized on their country's growing commercial ties to the world's largest drug market - the United States - to launch a global business.
