Key Discussion Points & Insights

1. The Supply Chain: From Leaf to Nose

• Origins of Cocaine (03:38)

  • Cocaine production begins in the mountains of Colombia, Bolivia, and Peru, where coca is cultivated by small farmers.
  • John Grillo: “These are not really cartel figures, organized crime figures. They're like small farmers who grow this crop and then they'll sell the leaves or they'll turn it into, into the paste.” (04:01)

• Processing and Standardization (04:13)

  • Farmers process leaves into coca paste, which is then refined into one-kilo bricks—the standard unit for trafficking.
  • Bricks are marked with producer seals to identify their origin and ownership.
  • John Grillo: “The kilo brick is really the operating unit of the cocaine trade...they are very, very standardized.” (04:21, 04:39)

• Evolution of Smuggling Routes (05:10)

  • Decades ago, cocaine often went straight from Colombia to the US. US crackdowns led traffickers to route through Mexico and Central America.
  • Mexico’s pre-existing smuggling infrastructure for marijuana and heroin made it a key transit hub.

• Corruption and Violence in Mexico (05:39)

  • As cocaine money flooded into Mexico, cartels bought off officials, politicians, and built armies of hitmen.
  • John Grillo: "You're buying off vast amounts of law enforcement and politicians...creating a real bloodbath in Mexico, pumping billions of dollars into this business." (05:39)

• The Venezuelan Shift (06:04)

  • US-Colombia crackdowns prompted traffickers to use Venezuela as a jumping-off point for flights to Honduras, Mexico, or other Caribbean locations.
  • Venezuela became a crucial hub, and its involvement in trafficking deepened.

2. How the Supply Chain Translates into Big Money (06:47)

• Each stage multiplies the value—by the time a kilo brick crosses the US border, its price skyrockets.
• John Grillo: “You could invest $1,000 and get back $10,000.” (06:52)
• After entering the US, cocaine is cut, repackaged, and sometimes converted into crack to sell at even higher prices—up to $60,000+ per kilogram.

3. Government Complicity and Indictments (08:07)

• The US government has accused top Venezuelan officials, including President Maduro, of facilitating cocaine shipments.
• Indictments reference the "Cartel de los Soles" (Cartel of the Suns), named after the sun emblem on Venezuelan military uniforms.
• John Grillo: “I do think there are credible accusations.” (08:32)
• Multiple sources, including traffickers and officials, describe active complicity by elements of the Venezuelan military and government in allowing and aiding cocaine flights.
  • “I did an interview with a guy who ran airplanes of cocaine. The Venezuelan government then were totally, you know, on board. They were allowing them to use the airports to move cocaine.” (08:58)

4. The Recent US Strikes and Legal Questions (09:21)

• The Trump administration justified recent attacks on ships and Venezuelan soil as targeting traffickers.
• Prior to these strikes, the US frequently intercepted drug boats off Venezuela—backs up smuggling claims but doesn't prove every interception involved cocaine.
• John Grillo: “They are involved in cocaine trafficking. But is that a reason to in itself to invade the country?” (09:48)
• International law experts widely condemned the January 3rd US strikes as illegal.

5. The Big Picture: Supply and Demand (10:14)

• The show closes by highlighting US and European demand as the ultimate driver for cocaine production, trafficking, and the resulting corruption and violence.
  • Darian Woods: “Of course, the US and Europe provide the demand for cocaine. That's what motivates turning a barrel of green leaves in the Andes into cocaine crystals...smuggled across the US and sold on the street.” (10:14)

Former Venezuelan leader Nicolas Maduro appeared in a New York court yesterday. He pleaded not guilty to drug trafficking and weapons charges. This is after an explosive abduction by US Forces in Caracas and is the culmination of months of American attacks on vessels in the Caribbean and Pacific north alleged to be carrying cocaine. The attacks have killed at least 115 people.

[Darian Woods]

The stated motivation for the Trump administration to depose Venezuela's leader extends far beyond cocaine. Trump has mentioned oil many times and also the migration of alleged Venezuelan criminals into the U.S. but the drug trafficking accusations against Maduro go back many years under both Republican and Democratic administrations. So we wanted to learn more about what cocaine trafficking looks like right now. This is the indicator from Planet Money. I'm Darian Woods.

[Stephen Bisaha]

And I'm Stephen Bisaha. Today on the show the cocaine Supply Chain, we trace the drug from leaf to nose and ask how the Venezuelan government might have been involved.

[NPR Announcer]

Hey there.

[Stephen Bisaha]

How you doing?

[John Grillo]

Good.

[Darian Woods]

Glad you could join me.

[Stephen Bisaha]

John Grillo is a journalist based in Mexico City and the author of the El Narco trilogy of his journalistic work. He's been on the drug trafficking beat for 25 years. And yet he's got a bit of firsthand experience from a military base in Mexico. A general once showed him a pile of seized cocaine.

[John Grillo]

He held the cocaine to me and he said, go on, have a taste. And I didn't know if he was joking, so I put my finger in the cocaine and licked it like that. And he said, oh, yeah, you can feel your tongue going numb, can't you?

[Darian Woods]

Yeah, I don't know what I would do in that situation, Stephen. Like, is he testing me?

[Stephen Bisaha]

Yeah, you're about to get arrested. The second you try, it's like, ah, we got you.

[Darian Woods]

Anyway, Jan says the cocaine trade starts in the high altitudes of Colombia, Bolivia and Peru. The that's where the coca plant is grown.

[John Grillo]

Quite an ordinary looking plant. It doesn't look actually anything too exotic when you see it. Kind of dark green leaves.

[Stephen Bisaha]

These coca leaves are harvested by the farmers living in those remote mountainous areas, often with pretty limited road access.

[John Grillo]

These are not really cartel figures, organized crime figures. They're like small farmers who grow this crop and then they'll sell the leaves or they'll turn it into, into the paste.

[Darian Woods]

That paste can be chucked in a backpack and taken by motorbike to the next step in processing, purification and crystallization.

[John Grillo]

These are quite expensive operations where you have quite a lot of equipment and you turn the paste into a kilo brick of cocaine. And the kilo brick is really the operating unit of the cocaine trade.

[Darian Woods]

They're standardized, I guess.

[John Grillo]

Yeah, yeah, they are very, very standardized, yeah, very standardized, yeah.

[Stephen Bisaha]

In fact, these kilo bricks are so standardized that cocaine producers will often put a seal on them to mark whose cocaine this actually is. And this is important because the cocaine producers are often different from the next stage in the chain. The trafficker. Trafficking these days rarely goes straight from Colombia like it used to several decades ago. Intense US law enforcement efforts meant that direct routes were too likely to get caught.

[John Grillo]

The traffickers then flipped and said, okay, we're gonna move it through Mexico and we'll go Colombia and sometimes bounce it through Central America. Move it through Mexico, and then we've got a 2,000 mile border to smuggle cocaine through. So then Mexico becomes a major transit country.

[Darian Woods]

Mexico already had the illicit smuggling infrastructure because of marijuana and heroin trafficking. And so the country was ripe for the cocaine trafficking trade. A tidal wave of new business.

[John Grillo]

You've got all of this cocaine money and then you're buying off vast amounts of law enforcement and Politicians and starting to build up armies of hitmen and create this, this real bloodbath in Mexico, pumping billions of dollars into this business.

[Stephen Bisaha]

In Mexico in the 2000s. At the same time, Mexico's role in the cocaine trade was growing. The US Government was working with Colombian authorities to really crack down on Colombian airspace.

[John Grillo]

So then it becomes easier for traffickers to flip to bring it over the border to Venezuela and then fly it from Venezuela on planes there. And fly it into. One route was fly it to Honduras, other routes fly it to Mexico on planes from Venezuela.

[Darian Woods]

So this is when cartels and groups start operating in Venezuela. Venezuela starts to become a more material player in the cocaine supply chain. Now we'll return to the question of whether the Venezuelan government is involved or how likely it is that those US Military strikes are, are actually hitting cocaine traffickers. For now, though, the bricks keep moving up the Caribbean, maybe over to Honduras perhaps, and up to the US Mexico border.

[Stephen Bisaha]

Once that brick gets across the US Border, Jan says the price goes way up.

[John Grillo]

They'll sell that in the U.S. border. It's a pretty big markup. I know most of us would love to be in that kind of business where you could invest $1,000 and get back $10,000.

[Darian Woods]

That's just the price. Once the brick hits the US the supply chain doesn't end there. Jan says that after the American trafficker has purchased their brick, they'll smuggle it across the US and sell them onto other groups who break down the bricks. Maybe they add fillers and other substances to make more money, and then they put it in bags as grams to sell on the street. Or they'll turn it into crack cocaine.

[Stephen Bisaha]

Thanks to solid demand for cocaine in the US the price of a gram could go anywhere between 60 and 200. In other words, that kilogram brick went from a price of about $2,000 in South America to $60,000 plus in the US a massive increase. But of course, there were a lot of expenses along the way, bribing vast.

[John Grillo]

Amounts of officials and paying for armors of killers and all of these kind of things.

[Darian Woods]

So a lot of money going to corrupt officials. Which brings us with the first big question is, is the Venezuelan government involved in the cocaine trade like the Trump administration claims?

[Stephen Bisaha]

According to an indictment from the United States against Nicolas Maduro and others unsealed this weekend, Maduro's government facilitated the importation of tons of cocaine into the United States. The indictment builds off a similar one in 2020 that describes Nicolas Maduro as leading what the US government calls the cartel de los Soles, the cartel of the suns. The sun being the symbol the Venezuelan military wears on their uniform.

[John Grillo]

I do think there are credible accusations.

[Darian Woods]

The reason Jan thinks this is because of his reporting over the years. Like a trafficker who moved cocaine from Venezuela to Mexico.

[John Grillo]

He described mass complicity of the Venezuelan military.

[Stephen Bisaha]

Also separately from a former drug czar from Honduras.

[John Grillo]

You know, see they were flying cocaine from Venezuela into Honduras at that time very openly.

[Stephen Bisaha]

And from others Yan's talk to.

[John Grillo]

I did an interview with a guy who ran airplanes of cocaine. The Venezuelan government then were totally, you know, on board. They were, they were allowing them to use the airports to move cocaine. So these are not claims that suddenly came from nowhere a couple of years ago. And familiarity with the cocaine trade around Latin America, there's immense corruption.

[Darian Woods]

So a lot of examples by plane. But that leads to our second big question. Were the vessels that were being blown up in the Caribbean and Pacific drug traffickers? The Trump administration says they were, but hasn't provided proof.

[Stephen Bisaha]

While we can't give answers for any individual case. Prior to these strikes, the US Southern Command was regularly intercepting similar boats in the same routes, hauling thousands of pounds worth of cocaine, often off the coast of Venezuela.

[John Grillo]

They are involved in cocaine trafficking. But is that a reason to in itself to invade the country?

[Darian Woods]

No.

[John Grillo]

You know, they do it for political reasons.

[Stephen Bisaha]

International law Experts condemn the U.S. s January 3rd strikes on Venezuelan soil as illegal. And President Trump himself has given shifting explanations for the invasion. Oil, gang migration and drugs.

[Darian Woods]

Of course the US And Europe provide the demand for cocaine. That's what motivates turning a barrel of green leaves in the Andes into cocaine crystals, trafficking them across land, sea and air to get to the Mexican border, smuggled across the US and sold on the street.
