Glyphosate case casts light on pesticide dilemma in cannabis industry

Posted on September 7th, 2018 by Bill Weinberg and tagged , , , , , , , , .

CaliforniaA verdict against glyphosate producer Monsanto in a case brought by a cancer sufferer has brought world attention to the dangers of pesticides and herbicides. This is a question with implications already felt in the cannabis industry—both legal and illegal.

A ground-breaking legal case on a popular herbicide producer's responsibility for cancers ended Aug. 10 when a San Francisco jury awarded $289 million in damages to a school grounds-keeper suffering from lymphoma.

As SFGate reported, the jury unanimously found that Monsanto was responsible for Dewayne "Lee" Johnson’s non-Hodgkin’s lymphoma and should have known of the threat posed by his on-the-job exposure to glyphosate, marketed by the company under the brand names Roundup and Ranger Pro. Jurors found that Monsanto had "acted with malice or oppression" when it sold glyphosate to Johnson's employer, the Benicia Unified School District, without informing of its potential health risks.

A growing concern in the legal industry
To what extent is this a concern for the cannabis industry—either for workers or consumers?

Lydia Abernethy, director of cultivation science for Berkeley-based cannabis testing facility Steep Hill Labs, told Cannabis Now, "Glyphosate is not one of the 66 residual pesticide chemistries required for safety testing by the Bureau of Cannabis Control. Steep Hill does not test for glyphosate in cannabis products or harvest batches, so we are unable to verify the presence of this chemical at this time." But she adds: "I would expect that cultivators use glyphosate products to control weeds on cultivation sites, either within the garden or around the outside of buildings. Prop 65 and negative press may be reducing the frequency these products are applied at cannabis grows, but I cannot confirm this."

Proposition 65— the Safe Drinking Water and Toxic Enforcement Act—is a right-to-know law concerning pesticides that approved by California voters in 1986. It requires the state to maintain a list of chemicals known to cause cancer or birth defects, and requires businesses to provide warnings prior to causing a significant exposure to a listed chemical. It also prohibits discharges of these substances into sources of drinking water.

Glyphosate was added to the Proposition 65 list by the state Office of Environmental Health Hazard Assessment (OEHHA) in March 2017—although it failed to immediately take effect due to a legal challenge launched by Monsanto. The change became official in July 201, when a Fresno judge ruled for the state in Monsanto v OEHHA. Although the case is on appeal, no stay of the listing has been granted. The listing took effect one year later—July 7, 2018. 

"Awareness of the human health risks from exposure to this chemical increases constantly," Abernethy elaborates. "Fear of product recalls and negative brand recognition should limit the liberally application of these products near cannabis crops, theoretically. Folks like Michael Murphy of the Clean Cannabis Initiative are bringing lawsuits to cannabis companies with detectable limits of pesticides in their products. However, until the BCC or another regulatory body (or third party secret shopper) does the residual pesticide testing to confirm the presence of this compound in cannabis products, it will be difficult to pin down the concentration and frequency of glyphosate contamination in this industry."

The notorious "Proposition 65 plaintiff" Michael Murphy and his Clean Cannabis Initiative are certainly pressing the Bureau of Cannabis Control on the matter. Last year, Murphy issued almost 700 Prop 65 "Notices of Violation" to cannabis dispensaries throughout California, alleging that their products contain such listed pesticides as myclobutanil, carbaryl and malathion.

And there has also been at least one recall related to this question. Marijuana Business Daily reported in July that a vape cartridge manufacturer issued the first cannabis product recall in California’s new regulated market. The Bloom Brand company and its manufacturer Greenfield Organix 4th St. voluntarily recalled four products, affecting nearly 100 retailers across California. "Batch Number B-180504 contains the pesticide Myclobutanil and does not comply with the Bureau of Cannabis Control (BCC) standards," the company wrote on its website.

Ecologically conscious cannabis cultivators and consumers in Northern California six years ago launched the Grow It in the Sun initiative, to reverse the trend toward hydroponic and advocate for organic outdoor cultivation. Of course, the legal industry has boomed since then, increasing the pressure on growers to use the most cost-effective methods. And, as a Bloomberg report noted last year, the problem is exacerbated by the failure of the federal Environmental Protection Agency to regulate even state-legal cannabis cultivation. 

An urgent issue in the illegal industry
If this question is an increasingly pressing one in the legal cannabis industry, it has reached crisis proportions in the illegal sector.

During the Operation Forest Watch eradication campaign in the foothills of the Sierra Nevada this summer, cultivation sites were found with a pink material originally thought to be fire retardant—but actually proved to be the toxic pesticide carbofuran.  "[T]hey'll put it around the base and they basically use it to...kill anything that tries to intercede with [the] growth of their plant, and it's very harmful, very dangerous," said Madera County Sheriff Jay Varney to local KFSN

Federal authorities report that 89% of illegal cannabis grows raided in California this year contained traces of potentially lethal pesticides, poisoning wildlife and posing a threat to water supplies. According to the Associated Press of Aug. 28, that's a big jump from 2017, when such chemicals found at about 75% of outlaw grow sites discovered on California's public lands. And this year's figure is six times higher than in 2012. Particularly named was carbofuran. Mourad Gabriel of the Integral Ecology Research Center in Humboldt County said this pesticide is so powerful that a quarter-teaspoon can kill a 300-pound bear.

Concern about the ecological impacts of cannabis cultivation have been mounting in recent years, and it was hoped that the day-lighting of the industry could meaningfully address the problem. This is another way in which the continued existence of an illegal sector poses a challenge to visions of a responsible industry.

Monsanto's public relations drive 
The Lee Johnson case was but one recent reversal in the courts for the pesticide industry. On Aug. 9, the 9th US Circuit Court of Appeals in San Francisco ordered the Environmental Protection Agency to remove the pesticide chlorpyrifos from sale in the United States within 60 days.

Monsanto is currently facing a surge in lawsuits, which could potentially cost its new owners, Bayer, billions in damages, BBC News reports. News of the verdict in the Johnson case sent Bayer's stocks plunging, according to Reuters—just two months after it acquired Monsanto.

After the verdict, The Guardian wrote that Monsanto "has spent decades convincing consumers, farmers, politicians, and regulators to ignore mounting evidence linking its glyphosate-based herbicides to cancer and other health problems. The company has employed a range of tactics—some drawn from the same playbook used by the tobacco industry in defending the safety of cigarettes—to suppress and manipulate scientific literature, harass journalists and scientists who did not parrot the company’s propaganda, and arm-twist and collude with regulators." The account noted that one of Monsanto’s lead attorneys in the San Francisco case was George Lombardi, who has also defending big tobacco in the courts. 

Laat year, the Chigaco-based progressive journal In These Times noted the work of the group Moms Across America, whose commissioned tests found glyphosate in breast milk samples (albeit within legal limits). Monsanto responded with a campaign to keep glyphosate (their most profitable product) on the market, agressively lobbying the EPA with its own studies contradicting the Moms Across America findings. These studies purported to be "independent," but were actually backed by the company.

Retrogression in Colombia
It's a grim irony that all this is happening just as Colombia is about to resume aerial spraying of glyphosate on the countryside of the Andean nation to wipe out illegal crops. As a June report in El Colombiano newspaper explained, this time the spraying will be carried out by drones rather than planes, to supposedly target the planted areas with greater precision. The report also notes that the move was undertaken under heavy pressure from the White House in response to booming coca cultivation in the country. Colombia suspended use of glyphosate against illegal crops in 2015, after the World Health Organization's International Agency for Research on Cancer (IARC) concluded that the herbicide "probably" causes cancer.

And while today the glyphosate spraying is overwhelmingly aimed at coca crops, it actually began in Colombia in the '70s to wipe out cannabis. Colombia's El Espectador ran a retrospective on the spray campaign when it came to a halt in 2015, noting that glyphosate was first used against cannabis plantations in the northern Sierra Nevada de Santa Marta in 1978. The anti-cannabis spraying continued at least through 1993, as coverage in Bogotá daily El Tiempo indicated. It was in this period that Colombia's old cannabis syndicates were morphing into the ultra-violent cocaine cartels—itself a bitter fruit of prohibition.

Ninth Circuit upholds judgment in Roundup case

Global Ganja Report's picture The US Court of Appeals for the Ninth Circuit upheld a $25 million judgment and jury verdict Friday finding that a California man, Edwin Hardeman, developed cancer from exposure to Bayer's weed-killer Roundup.


Hardeman alleged that he developed non-Hodgkin’s lymphoma as a result of the use of Roundup on his property in Windsor, Calif., over decades. In 2019, the jury found that the manufacturer was negligent, and the design on Roundup lacked sufficient cancer warnings. The jury awarded Hardeman $75 million in punitive damages, but the federal judge overseeing the trial reduced the punitive damages to $20 million. The jury also awarded Hardeman $5 million in compensatory damages for past and future pain and suffering. (Jurist)

SCOTUS rejects Bayer bid to stop Roundup lawsuits

Global Ganja Report's picture The Supreme Court has rejected Bayer's appeal to shut down thousands of lawsuits claiming that its Roundup weedkiller causes cancer. The justices on June 21 left in place a $25 million judgment in favor of Edwin Hardeman, a California man who says he developed cancer from using Roundup for decades to treat poison oak and weeds on his San Francisco Bay Area property. Hardeman's lawsuit had served as a test case for thousands of similar suits.

The high court's action comes amid a series of court fights over Roundup that have pointed in different directions. On June 17, a panel of the 9th Circuit Court of Appeals rejected an Environmental Protection Agency finding from 2020 that glyphosate does not pose a serious health risk and is "not likely" to cause cancer in humans. The appellate court ordered the EPA to reexamine its finding. (AP)

SCOTUS rejects Bayer bid to stop Roundup lawsuits —again

Global Ganja Report's picture The US Supreme Court denied certiorari June 27 to pharmaceutical giant Bayer and agrochemical subsidiary Monsanto for the second time this year. Bayer has been seeking certiorari for one of many cases surrounding Roundup, a weed killer produced by Monsanto with alleged cancer-causing properties. The case in question, Pilliods v. Monsanto, concerns a California couple who claim Roundup's key ingredient, glyphosate, caused both of their non-Hodgkin’s lymphoma diagnoses. The California Appeals Court held in the couple's favor, ordering Bayer and Monsanto to pay $86 million in damages (both punitive and compensatory). (Jurist)
