Documents & Timeline

1989 Nov 19 [Wrong date on document] The Environmenal Protection Agency (EPA) was in the process of publicly asserting that second-hand smoke (ETS) was a known carcinogen ("risk assessment").

This is a draft speech script prepared for a media briefing by Dr Don de Bethizy, sentior toxicologist at RJ Reynolds. They have lined up all the industry's favourite scientific touts who are being paid to attack

..."the scientific merit of two EPA draft documents -- the ETS risk assessment and the workplace smoking guide" [which he says] contain many major scientific shortcomings. The time we have today only permits us to scratch the surface.

[In fact they dug out the deepest slime in the pit. Every scientist mentioned here is a long-term tobacco industry science-for-sale entrepreneur or witness for hire.]

Today, you'll hear why

• Gray Robertson, an internationally regarded expert on indoor air quality, believes the Workplace Smoking Guide is poorly conceived, with conclusions that are ill-considered.

  [Robertson was the owner of ACVA/HBI -- the most corrupt of all the indoor air testing company employed by the tobacco industry. He was one of the industry's main contract lobbyists.]

• After Gray Robertson, you'll hear from Dr Phil Witorsch, pulmonary physician and a clinical professor of medicine at George Washington University Medical Center. He will detail the specific reasons he believes the EPA has drawn invalid from evidence concerning the relationship between ETS and respiratory diseases in children.

  [He spent most of his time as a tobacco consultant lobbyist, travelling around the world to provide witness services for the tobacco industry in court cases. He was a founding member of the notorious IAPAG (Indoor Air Pollution Advisory Group) which was a 'WhiteCoats' organisation run by tobacco lawyers Covington & Burling.]

• Dr. John Wesley Clayton, professor emeritus of pharmacology and toxicology at the University of Arizona, and former president of the International Congress of Toxicologists, will discuss the available toxicological data on ETS. None of these data appears in the Risk Assessment. And -- more important -- none supports the contention that ETS is a human carcinogen.

  [Clayon had then been receiving CTR grants for 15 years, and in return, on his retirement, he had become a professional witness who worked extensively for the Tobacco Institute (and probably any other industry with the funds). He was handled by lawyers Shook Hardy & Bacon.]

• Dr Maurice E LeVois, a highly experienced epidemiologist who has designed large studies for the US government will detail some important omissions in the Risk Assessment. As Dr LeVois will point out,the draft arbitrarily omits important epidemiological, dosimetric, medical and statistical evidence that conflicts with the conclusions reached by the EPA.

  [LeVois was, at various times, the partner of Max Layard and also George Carlo -- both notorious science-for-sale entrepreneurs (Carlo also for the cellphone industry). During the 1990s they worked almost full-time for two industries -- tobacco and dioxin/herbicides -- mainly through infiltrating organisations like Veterams Affairs and conducting their fake studies]

• Dr. Richard L Tweedie, the dean of information and computing sciences at Bond University in Australia, will present the findings of his own analysis of the epidemiologic studies conducted on ETS. And he will discuss some major differences between his conclusions and those reached by the EPA.

  [Tweedie and his girlfriend (also a long-term tobacco tout) Kerry Mengerson were rewarded with an endowed chair at the University of Colorado]

• Peter N. Lee, a British statistician whose work is frequently cited by the EPA in the Risk Assessment, will explain why the misclassification adjustment made by the EPA is mathematically incorrect.

  [Lee spent his life as a full-time contractor in statistics to the Tobacco Advisory Committee (TAC) of the UK. He was retained to try to find holes in any adverse scientific finding.]

  Dr William J. Butler, a biostatistician, will focus on the EPA's failure to identify or discuss several important confounding factors that could account for most -- if not all -- of the increased risk noted by the EPA.

  [Butler was a contract scientific lobbyist from the company Failure Anaiysis, Inc. Butler and this company worked extensively for the tobacco industry: he was one of their regular witnesses used with State Assembly hearings. He also spoke at Philip Morris's closed McGill Uni. ETS symposium -- which only enrolled paid industry touts.]

• Dr Joseph L Fleiss, the head of the division of biostatistics at the Columbia University School of Public Health, will discuss a number of considerations that make meta-analyis an invalid basis for drawing conclusions about ETS.

  [A regular Tobacco Institute consultant and speaker used at fake/closed conferences. (McGill Uni.)]

• Dr. Paul Switzer, a professor of statistics at Stanford University, will focus on a number of statistical uncertainties, inconsistencies and biases that seriously undermine the scientific credibility of the Risk Assessment.

  [Another regular scientific witness who also played a key role in the loaded McGill University ETS Symposium,]

• Finally, Dr W Gary Flamm, the president of the International Society for Regulatory Toxicology & Pharmacology, will talk about serious violations of scientific objectivity contained within the .document. [

  The Society was a front for a group of science-for-sale toxicologist who worked for a range of industries with poisoning and polluting problems. Flamm also lectured at McGill.]
