Banners say Mexican gang has sworn off fentanyl sales

MEXICO CITY — Banners appeared this week in northern Mexico purportedly signed by a faction of Mexico’s Sinaloa cartel claiming that the gang has sworn off the sale and production of the synthetic opioid fentanyl.

But experts quickly cast doubt on the veracity of the claim, saying that fentanyl — which has caused tens of thousands of overdose deaths in the United States — remains one of the cartel’s biggest money makers.

Prosecutors in Sinaloa confirmed that the banners appeared on overpasses and near roadways, but could not say whether they were authentic or who had hung them up.

The machine-printed banners purportedly signed by the sons of imprisoned drug lord Joaquin “El Chapo” Guzman claim they have prohibited the sale or production of fentanyl in the northern state of Sinaloa. The sons are known as “the Chapitos” after their famous father.

“In Sinaloa, the sale, manufacture, transport or any other business dealing with fentanyl, is strictly prohibited, including the sale of chemicals used to produce it,” the banners read. “You have been warned. Respectfully, Chapitos.”

Mike Vigil, former head of international operations for the Drug Enforcement Administration, said there is concrete evidence that “Sinaloa is the biggest producer of fentanyl in Mexico” and that there has been no sign the cartel is moving away from it.

“I think the Chapitos started feeling the pressure when they increased the reward for their capture. I think they are trying to create a massive illusion to take the pressure off,” he said. “It’s almost like a big campaign to convince the U.S. they’re not involved. It’s nothing more than pure propaganda,” Vigil said.

In September, Mexico extradited Ovidio Guzmán López, one of the Chapitos, to the United States to face drug trafficking, money laundering and other charges. Mexican security forces captured Guzmán López, alias “the Mouse,” in January in Culiacan, capital of Sinaloa state, the cartel’s namesake.

In May, the Chapitos claimed in a letter that they were not involved in the fentanyl trade. The sons of Guzmán wrote at the time that “we have never produced, manufactured or commercialized fentanyl nor any of its derivatives,” the letter said. “We are victims of persecution and have been made into scapegoats.”

Vigil maintained it was untrue that the cartel would stop producing fentanyl because, “that is their big money maker.” He also said that the rest of the Sinaloa Cartel “would never go along with” any move to stop the lucrative production.

“The Sinaloa Cartel strategy is to move away from plant-based drugs” like cocaine, marijuana and heroin, Vigil said. Giving up fentanyl — which could strengthen the rival Jalisco gang — “is going to give Jalisco the keys to basically overshadow them in terms of money.”

An estimated 109,680 overdose deaths occurred last year in the United States, according to the CDC. About 75,000 of those were linked to fentanyl and other synthetic opioids.
