#397 - "We're Under Siege" China's New Deal With The Sinaloa Cartel | John Nores
"The US Fish and Wildlife Service had a monetary value of $35,000 to $40,000 per steelhead trout. These guys take that stuff, take it to send in a water bottle and mix it up and shake it, or put half of a whole container inside a backpack sprayer with 6 gallons of water, and they're hosing down marijuana plants. If a black bear comes in, licks a drop of that stuff in tuna oil, 15 minutes, this 400-pound black bear frothing at the mouth, central nervous system seizes. They're done."
Nores revealed that cartel growers are using EPA-banned nerve agent insecticides like carbofuran on marijuana crops in concentrated, undiluted doses. The toxins kill endangered wildlife including bears and fish, and exposure has left law enforcement officers temporarily blind or seriously ill. The growers call the poison 'El Diablo' and knowingly apply it despite its lethality, creating a public health crisis as the contaminated marijuana enters the black market across the United States.

About this episode

In this episode, host Danny Jones sits down with retired California game warden John Nores, who spent nearly 30 years battling Mexican and Chinese cartel operations on American public lands. Nores recounts how a routine wildlife enforcement career transformed into a hidden war after he discovered armed Sinaloa Cartel growers operating near Silicon Valley in 2004. The conversation centers on a shocking 2005 incident in which one of Nores' officers was shot by cartel gunmen during a raid in the Los Gatos foothills, marking the first time any U.S. law enforcement officer had been shot by marijuana growers tied to organized crime. Nores explains how cartel operations employ EPA-banned nerve agent insecticides like carbofuran on marijuana crops, killing endangered wildlife and sickening officers, while producing poison-tainted weed that floods the black market nationwide. He reveals that a captured Sinaloa plaza boss openly referred to California as 'Mexico North' and detailed how deported growers are smuggled back across the border within days for as little as four thousand dollars. The episode takes a geopolitical turn as Nores describes recent Chinese cartel involvement, explaining that Chinese criminal organizations now partner with Mexican cartels to dominate black market marijuana while laundering fentanyl cash and supplying precursor chemicals from mainland China. Nores, who now lives in Montana, warns that as the southern border tightened under recent enforcement, cartel operations have shifted to the largely undefended 5,000-mile northern border, where fentanyl is manufactured in Canadian labs and walked across remote forest trails into American communities. He criticizes California's Proposition 64 for reducing illegal growing penalties from felonies to misdemeanors, effectively eliminating deterrence and allowing cartel grows to explode across multiple states. Throughout, Nores calls for national prioritization of the issue, arguing it represents the greatest domestic threat to American wildlife, public lands, and youth safety.
