Geoffrey Kabat’s Ties to Tobacco and Chemical Industry Groups

Print Email Share Tweet

Geoffrey Kabat, PhD, is a cancer epidemiologist and author of two books arguing that that health hazards of pesticides, electromagnetic fields, secondhand tobacco smoke and other environmental exposures are “greatly overblown.” He is often quoted in the press as an independent expert on cancer risk. Reporters who use Dr. Kabat as a source should be aware of (and disclose) his longstanding ties to the tobacco industry and involvement with groups that partner with the chemical industry on PR and lobbying campaigns.

Front group leader and advisor

Dr. Kabat is a member of the board of directors of the Science Literacy Project, the parent group of Genetic Literacy Project, which works behind the scenes with Monsanto to promote and defend agrichemical products. Dr. Kabat is also a member of the board of scientific advisors of the American Council on Science and Health (ACSH), a group that receives funding from chemical, tobacco and pharmaceutical companies.

Both Genetic Literacy Project and ACSH partnered with Monsanto on a public relations campaign to attempt to discredit the International Agency for Research on Cancer (IARC) for its report that glyphosate, the main ingredient in Monsanto’s Roundup herbicide, is a probable human carcinogen. According to documents released via litigation:

  • A Monsanto PR plan (February 2015) named Genetic Literacy Project among the “industry partners” Monsanto planned to engage in its efforts to “neutralize [the] impact” of the IARC report. The goals of Monsanto’s plan were to “protect the reputation and FTO of Roundup” and “provide cover for regulatory agencies…” GLP has since posted more than 200 articles critical of the cancer agency.
  • Emails from February 2015 show that Monsanto funded ACSH on an ongoing basis and reached out to give ACSH the “full array” of Monsanto information about the IARC report on glyphosate. In the emails, Monsanto staffers discussed the usefulness of ACSH’s materials on pesticides, and one wrote, “You WILL NOT GET A BETTER VALUE FOR YOUR DOLLAR than ACSH.” (emphasis in original)
  • ACSH staffers told Monsanto the IARC glyphosate report was on their radar, and noted, “We are involved in a full-court press re: IARC, regarding ag-chemicals, DINP [phthalate] and diesel exhaust.”

These groups used similar messaging to attack the IARC cancer researchers as “scientific frauds” and “anti-chemical enviros” who “lied” and “conspired to misrepresent” the science on glyphosate. They cited Dr. Kabat as a key source for claims that IARC is “discredited” and “only enviro-fanatics” pay attention to reports on cancer hazard. Dr. Kabat has written that “there are literally no more studies we can do to show glyphosate is safe,” based on an interview with an anonymous expert.

Attacking scientists who raise cancer concerns

Another example of how Dr. Kabat aids the Monsanto-connected groups can be found in his efforts to discredit a different group of scientists who raised cancer concerns about glyphosate in a February 2019 meta-analysis. The meta-analysis, co-authored by three scientists who were tapped by EPA to serve on an expert scientific advisory committee on glyphosate, reported “compelling links” between exposures to glyphosate-based herbicides and increased risk of non-Hodgkin lymphoma.

Dr. Kabat skewered the analysis in an article that was first published on Forbes but was later removed after Forbes editors received complaints about Kabat’s lack of disclosure about his ties to ACSH. When questioned about the issue, Forbes said the article was pulled because it violated Forbes standards and Kabat would no longer be a contributor to Forbes.

Dr. Kabat’s deleted Forbes article can still be read on Science 2.0, a website run by the former director of ACSH, and a version appears on Genetic Literacy Project. GLP Executive Director Jon Entine promoted Dr. Kabat’s article along with suggestions that the scientists may have committed “deliberate fraud.”

Jon Entine is also tied in with the American Council on Science and Health. ACSH published Entine’s 2011 book that defends atrazine, a pesticide manufactured by Syngenta, which was funding ACSH.

Dr. Kabat’s longstanding tobacco ties

Dr. Kabat has published several papers favorable to the tobacco industry that were funded by the tobacco industry. He and his co-author on some of those papers, James Enstrom (a trustee of the American Council on Science and Health), have longstanding ties to the tobacco industry, according to a 2005 paper in BMJ Tobacco Control.

In a widely cited 2003 paper in BMJ, Kabat and Enstrom concluded that secondhand smoke does not increase the risk of lung cancer and heart disease. The study was sponsored in part by the Center for Indoor Air Research (CIAR), a tobacco industry group. Although that funding was disclosed, a follow-up analysis in BMJ Tobacco Control found that the disclosures provided by Kabat and Enstrom, although they met the journal’s standards, “did not provide the reader with a full picture of the tobacco industry’s involvement with the study authors. The tobacco industry documents reveal that the authors had long standing financial and other working relationships with the tobacco industry.” (emphasis added)

This table in the BMJ Tobacco Control paper reports the early ties:

In 2019, a search for Geoffrey Kabat in the UCSF Tobacco Industry Documents brings up over 800 documents, including a 2007 invoice to Phillip Morris for over $20,000 for “consulting on the health effects of low-yield cigarettes” billed at $350 an hour.

In 2008, Kabat and Enstrom published a paper partly funded by Phillip Morris reporting that previous assessments appeared to have overestimated the strength of the association between environmental tobacco smoke and coronary heart disease.

In 2012, Dr. Kabat co-authored a paper finding that mentholated cigarettes were not an important contributor to esophageal cancer. For that paper, Dr. Kabat declared he had “served as a consultant to a law firm and to a consulting firm on the health effects of menthol cigarettes.”

The American Council on Science and Health is a Corporate Front Group

Updated in July 2019

The American Council on Science and Health (ACSH) calls itself a “pro-science consumer advocacy organization” and media outlets often quote the group as an independent science source; however, documents described in this fact sheet establish that ACSH is corporate front group that solicits money from tobacco, chemical, cosmetic, pharmaceutical and other companies in exchange for defending and promoting their products. The group does not disclose its funding.

Key documents:

  • Emails from 2015 released via discovery reveal that Monsanto funded ACSH and asked the group to help defend glyphosate.
  • Leaked financial documents from 2012 establish that ACSH solicits money from corporations for product defense campaigns. Donors include a wide array of companies and industry groups.
  • Emails from 2009 show that ACSH solicited $100,000 from Syngenta to write a paper and book about Syngenta’s pesticide atrazine. In 2011, ACSH released a book by Jon Entine similar to the project described in the email.
  • Syngenta and Monsanto have been regular contributors to ACSH over the years, the emails show.

Monsanto funds ACSH to defend Monsanto products

Emails released in April 2019 reveal that Monsanto agreed to fund ACSH in 2015 and asked the group to help defend glyphosate from cancer concerns raised by the International Agency for Research. ACSH agreed to do so, and later attacked the cancer report as a “scientific fraud.” The emails illuminate ACSH’s reliance on corporate funding and efforts to please its funders. ACSH’s former acting director Gil Ross (who spent time in jail for Medicaid fraud) wrote to a Monsanto executive, “Each and every day, we work hard to prove our worth to companies such as Monsanto.” Ross wrote:

Emails also show that Monsanto executives paid ACSH despite their discomfort with the group. Monsanto’s senior science lead Daniel Goldstein championed ACSH to his colleagues, and sent them links to 53 ACSH articles, two books and a pesticide review he described as as “EXTREMELY USEFUL.” Goldstein wrote:

Key player in Monsanto’s propaganda network

An award-winning investigation by Le Monde into Monsanto’s “war on science” to defend glyphosate named the American Council on Science and Health among the “well known propaganda websites” that played a key role in attacking the scientists who raised cancer concerns. In May 2017, plaintiffs’ attorneys suing Monsanto over glyphosate cancer concerns stated in a brief: “Monsanto quietly funnels money to ‘think tanks’ such as the ‘Genetic Literacy Project’ and the ‘American Council on Science and Health,’ organizations intended to shame scientists and highlight information helpful to Monsanto and other chemical producers.”

Emails obtained by U.S. Right to Know reveal that Monsanto initially chose ACSH to publish a series of pro-GMO papers that were assigned to professors by Monsanto and “merchandized” by a PR firm to heavily promote them as independent. Monsanto executive Eric Sachs wrote to the professors: “To ensure that the papers have the greatest impact, the American Council for Science and Health is partnering with CMA Consulting to drive the project. The completed policy briefs will be offered on the ACSH website … CMA and ACSH also will merchandize the policy briefs, including the development of media specific materials, such as op-eds, blog postings, speaking engagements, events, webinars, etc.” The papers were eventually published by Genetic Literacy Project with no disclosure of Monsanto’s role.

In a report from the U.S. House of Representatives, congressional investigators stated that Monsanto uses “industry trade groups, such as CropLife and industry front groups, such as Genetic Literacy Project and Academics Review as platforms of support for industry spokespersons.”

Leaked ACSH docs reveal corporate-defense funding strategy

A leaked 2012 ACSH financial summary reported by Mother Jones revealed that ACSH has received funding from a large number of corporations and industry groups with a financial stake in the science messaging ACSH promotes — and showed how ACSH solicits corporate donations for quid pro quo product-defense campaigns. For example, the document outlines:

  • Plans to pitch the Vinyl Institute which “previously supported chlorine and health report”
  • Plans to pitch food companies for a messaging campaign to oppose GMO labeling
  • Plans to pitch cosmetic companies to counter “reformulation pressures” from the Campaign for Safe Cosmetics
  • Efforts to court tobacco and e-cigarette companies

Mother Jones reported, “ACSH’s donors and the potential backers the group has been targeting comprise a who’s-who of energy, agriculture, cosmetics, food, soda, chemical, pharmaceutical, and tobacco corporations.” Funding details:

  • ACSH donors in the second half of 2012 included Chevron, Coca-Cola, the Bristol Myers Squibb Foundation, Dr. Pepper/Snapple, Bayer Cropscience, Procter and Gamble, Syngenta, 3M, McDonald’s, and tobacco conglomerate Altria. ACSH also pursued financial support from Pepsi, Monsanto, British American Tobacco, DowAgro, ExxonMobil Foundation, Philip Morris International, Reynolds American, the Koch family-controlled Claude R. Lambe Foundation, the Dow-linked Gerstacker Foundation, the Bradley Foundation and Searle Freedom Trust.
  • Reynolds American and Phillip Morris International were the two largest donors listed in the documents.

Syngenta funding, Syngenta defense

In 2011, ACSH published a book about “chemophobia” written by Jon Entine, who is now the executive director of the Genetic Literacy Project, another front group that works with Monsanto. Entine’s ACSH book defended atrazine, a pesticide manufactured by Syngenta, which was funding ACSH.

A 2012 Mother Jones article describes the circumstances leading up to the book. The article by Tom Philpott, based in part on internal company documents obtained by the Center for Media and Democracy, describes Syngenta’s PR efforts to get third-party allies to spin media coverage of atrazine.

In one email from 2009, ACSH staff asked Syngenta for an additional $100,000 – “separate and distinct from general operating support Syngenta has been so generously providing over the years” – to produce an atrazine-friendly paper and “consumer-friendly booklet” to help educate media and scientists.

Email from ASCH staffer Gil Ross to Syngenta about proposed atrazine project:

A year and a half later, ACSH published Entine’s book with a press release that sounds similar to the project Ross described in his solicitation email to Syngenta: “The American Council on Science and Health is pleased to announce a new book and companion friendly, abbreviated position paper” in response to the “irrational fear of chemicals.” Author Jon Entine denied any relationship with Syngenta and told Philpott he had “no idea” Syngenta was funding ACSH.

ACSH personnel

  • ACSH’s longtime “Medical/Executive DirectorDr. Gilbert Ross was convicted in a scheme to defraud the Medicaid system prior to joining ACSH. See court documents about Dr. Ross’ multiple fraud convictions and sentencing, and article in Mother Jones “Paging Dr. Ross” (2005). Dr. Ross was found to be a “highly untrustworthy individual” by a judge who sustained the exclusion of Dr. Ross from Medicaid for 10 years (see additional references and court document).
  • In June 2015, Hank Campbell took over ACSH leadership from acting president (and convicted felon) Dr. Gilbert Ross. Campbell worked for software development companies before starting the website Science 2.0 in 2006. In his 2012 book with Alex Berezow, “Science Left Behind: Feel Good Fallacies and the Rise of the Anti Science Left,” Campbell describes his background: “six years ago… I decided I wanted to write science on the Internet … with nothing but enthusiasm and a concept, I approached world famous people about helping me reshape how science could be done, and they did it for free.” Campbell left suddenly under unknown circumstances in December 2018. Read more about Campbell here.
  • Campbell’s book co-author, Alex Berezow, is now vice president of scientific affairs at ACSH.  He is a founding editor of Real Clear Science and is on the USA Today editorial board of contributors but USA Today does not disclose Berezow’s ACSH affiliation or ACSH’s corporate funding despite repeated complaints (more info below).

Leaders and advisors: tobacco ties and climate science denial  

The ACSH board of trustees includes Fred L. Smith Jr., founder of the Competitive Enterprises Institute, a leading promoter of climate science denial and a group that has received millions of dollars from Exxon Mobile and dark money funding vehicle Donors Trust.  Smith and CEI also have a history of fighting against tobacco regulations and soliciting money from the tobacco industry, according to documents from the UCSF Truth Tobacco Industry Documents archive. 

James Enstrom and Geoffrey Kabat, two epidemiologists who took money from tobacco companies and wrote studies defending tobacco products, also have ACSH ties. Dr. Enstrom is a member of the ACSH board of trustees and Dr. Kabat serves on the “health board of scientific advisors“. Both scientists have “long standing financial and other working relationships with the tobacco industry,” according to a paper in BMJ Tobacco Control.

In a widely cited 2003 paper in BMJ, Kabat and Enstrom concluded that secondhand smoke does not increase the risk of lung cancer and heart disease. The study was sponsored in part by the Center for Indoor Air Research (CIAR), a tobacco industry group. Although that funding was disclosed, a follow-up analysis in BMJ Tobacco Control found that the disclosures by Enstrom and Kabat “did not provide the reader with a full picture of the tobacco industry’s involvement with the study authors.” The paper details numerous financial ties between Enstrom and the tobacco industry.

Emails from 2014 feature Dr. Enstrom discussing with famous climate science denier Fred Singer ideas to attack and discredit two scientists who were involved in the film “Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming,” and whether to try to stop the release of the film with a lawsuit. For more information, see DeSmog blog, “Tobacco Gun for Hire James Enstrom, Willie Soon and the Climate Deniers Attack on Merchants of Doubt” (March 2015).

Dr. Kabat is also on the board of directors of the parent organization of the Genetic Literacy Project, a front group that works with Monsanto on PR projects while claiming to be independent. Read more about his work in our fact sheet, Geoffrey Kabat’s Ties to Tobacco and Chemical Industry Groups

Incorrect statements about science 

American Council on Science and Health has claimed:

  • “There is no evidence that exposure to secondhand smoke involves heart attacks or cardiac arrest.” Winston-Salem Journal, 2012
  • “there is no scientific consensus concerning global warming.” ACSH, 1998 (Greenpeace has described ACSH a “Koch Industries climate denial front group”)
  • fracking “doesn’t pollute water or air.” Daily Caller, 2013
  • “There has never been a case of ill health linked to the regulated, approved use of pesticides in this country.” Tobacco Documents Library, UCSF, The Advancement of Sound Science Coalition document page 9, 1995
  • “There is no evidence that BPA [bisphenol A] in consumer products of any type, including cash register receipts, are harmful to health.” ACSH, 2012
  • exposure to mercury, a potent neurotoxin, “in conventional seafood causes no harm in humans.” ACSH, 2010.

Recent ACSH messaging continues in the same theme, denying risk from products that are important to the chemical, tobacco and other industries, and making frequent attacks on scientists, journalists and others who raise concerns.

  • A 2016 “top junk science” post by ACSH denies that chemicals can cause endocrine disruption; defends e-cigarettes, vaping and soda; and attacks journalists and the Journal of the American Medical Association.

USA Today gives ACSH a platform 

USA Today continues to publish columns by ACSH staffers Hank Campbell and Alex Berezow without disclosing their funding ties to corporations whose interests they defend. In February 2017, 30 health, environmental, labor and public interest groups wrote to the editors of USA Today asking the paper to stop providing a platform of legitimacy to ACSH or at least provide full disclosures about who funds the group.

The letter states:

  • “We are writing to express our concern that USA Today continues to publish columns written by members of the American Council on Science and Health (ACSH), a corporate-funded group with a long history of promoting corporate agendas that are at odds with mainstream science. USA Today should not be helping this group promote its false identity as a credible, independent source on science. Your readers deserve accurate information about what and whom this group represents, as they reflect on the content of the columns.”
  • “These are no idle allegations. Many of the undersigned health, environmental, labor and public interest groups have been tracking ACSH’s work over the years. We have documented instances in which the group has worked to undermine climate change science, and deny the health threats associated with various products, including second-hand smokefrackingpesticides and industrial chemicals – all without being transparent about its corporate backers.”
  • We note that financial documents obtained by Mother Jones show that ACSH has received funding from tobacco, chemical, pharmaceutical and oil corporations. Public interest groups have reported that ACSH received funding from the Koch Foundations between 2005-2011, and released internal documents showing that ACSH solicited $100,000 from Syngenta in 2009 to write favorably about its product atrazine – a donation that was to be “separate and distinct from general operating support Syngenta has been so generously providing over the years.”
  • “At a time when the public is questioning the legitimacy of the news media, we believe it is vital for publications such as USA Today to follow the highest standards of journalistic ethics and serve the public with as much truth and transparency as possible. We respectfully ask you to refrain from publishing further columns authored by members of the American Council on Science and Health, or at the very least require that the individuals identify the organization accurately as a corporate-funded advocacy group.”

As of December 2017, USA Today editorial page editor Bill Sternberg has declined to stop publishing ACSH columns and the paper has repeatedly provided inaccurate or incomplete disclosures for the columns, and failed to notify its readers about ACSH’s funding from corporations whose agenda they promote.
