An alarming increase in the use of a highly toxic and banned pesticide at illegal marijuana farms hidden on public land in California is leading U.S. and state officials to team up on an issue that recently divided them: pot.
They announced Tuesday that they will use $2.5 million in federal money to target illegal grows even as they remain at odds over the drug and other issues. Federal law still bans pot, but U.S. Attorney McGregor Scott said he will prioritize illegal weed rather than going after the world’s largest legal recreational marijuana market, a decision U.S. Attorney General Jeff Sessions has left to the discretion of top federal prosecutors.
“The reality of the situation is there is so much black market marijuana in California that we could use all of our resources going after just the black market and never get there,” Scott said.
“So for right now, our priorities are to focus on what have been historically our federal law enforcement priorities: interstate trafficking, organized crime and the federal public lands,” said Scott, whom President Donald Trump appointed last year as U.S. attorney of inland California, from Bakersfield northward.
Most of illegally grown California pot is destined for Midwestern and Eastern states where it is more profitable. California Attorney General Xavier Becerra and others referred to the illegal grows as California’s new Gold Rush, bringing both riches and environmental devastation.
“You’ve got to make it so crime doesn’t pay,” Becerra said.
The illegal grows, where the highly toxic pesticide Carbofuran is prevalent, pose an increasing threat to water, wildlife and ultimately people, officials said. Researcher Mourad Gabriel said he and his colleagues found the chemical at 72 percent of grow sites last year, up from 15 percent in 2012.
About 60 percent of California’s water supply flows through national forests, and researchers found that 40 percent of water samples downstream from illegal grows are contaminated.
Gabriel’s research found that traces of the pesticide are now showing up in pot, though he did not attempt to quantify how much was in each sample or its effects on people. Such dangers have long been an issue in unregulated drug markets, something California’s new legal pot market intends to change.
Carbofuran, which can’t legally be used in the U.S., is meant to be heavily diluted and used as an insecticide. It is so powerful, a quarter of a teaspoon of concentrate can kill a 300-pound bear, said Gabriel, executive director and senior ecologist at Integral Ecology Research Center, one of the few researchers studying the ecological impact of illicit grow sites.
It’s also being used on pot plants in barely diluted form. Carbofuran is being smuggled in from Mexico by drug cartels and laborers hired to clear forestland and replant it with illegal marijuana, Scott said.
