Day 194: The disturbing revelations by - and about - Albert Liston

As far as I know, this week was one of the very few times in Canadian history that a former senior bureaucrat has been held accountable in court about the management of the tobacco file.

Nevermind that the federal government has been excused from this case. Nevermind that Albert Liston, the former Assistant Deputy Minister at Health Canada, was a witness and not a defendant. Nevermind that Justice Riordan has a mandate to pronounce on whether the tobacco companies acted in ways that harmed smokers' health, but has no responsibility to say whether the government did too.

Despite all of the above, the spotlight was on the thoughts and actions of one man who once sat at the top of the mammoth (2000 or more) scientific branch of Health Canada. It was Mr. Liston that the tobacco companies had chosen as their shield, and it was Mr. Liston who had testified yesterday in support of the company's positions on addiction and warnings. And so it was Mr. Liston who was the object of a gruelling day's cross-examination by the plaintiffs in the Montreal tobacco trials.

Gruelling, yes, but not aggressive. Plaintiff lawyer Bruce Johnston kept his elbows in, exercising a restraint in the tone, scope and phrasing of his questions that earned him the support of Justice Riordan and - after a bit of scolding from the judge -- mostly kept the defendant lawyers from finding a basis to object and interrupt the flow of the exchange.

The morning was one of the most intense of this trial. Colleagues from the health community sitting behind me were leaning forward in their chairs, and barely a muscle twitched in the more than a dozen lawyers seated ahead of the bar.

The last man standing

There were some unpleasant truths in Mr. Liston's testimony, but there was no chance of reconciliation with the rest of the government's record.

Of the two-dozen former employees or contractors once fingered as potential witnesses, only Mr. Liston remained on the list. (Two others - former Minister Marc Lalonde and current director of regulation Denis Choinière - testified in June). A comparative list is shown below.

There was no government lawyer in the courtroom. No one available to defend the public record against the revelations that the man in charge of tobacco regulation never believed that cigarettes caused disease, never accepted that they were addictive in the medical sense, and never believed that there were measurable amounts of second hand smoke in Canadian homes. Not even someone to take notes.

An affair to forget

Sprinkled throughout the day were questions to Mr. Liston about his relationship with the tobacco companies since his retirement from Health Canada in 1992. He worked with the companies from at least 1994 and closed his consultancy in around 2005. Since then, he said, he had not billed the companies for any work. He was not being reimbursed for his appearance at this trial.

Mr. Liston had been subpoenaed with a request to bring with him records of his consulting relationship with the tobacco companies, but the only documents he could locate were an excel table of billings for the years 1995 to 2000. Any other material had been "purged" - "I had no use and they were intrusive in my home."  The loss of any electronic records he blamed on migration from one operating system to another as his computers changed.

The records of billings that remained - Exhibit 1650 - showed that Mr. Liston charged $200 an hour, and that the work he billed for included database searches at quasi-governmental agency, the Canadian Centre on Substance Abuse. It is not clear whether this was during the same period that he was a board member of the CCSA, or why tobacco industry consultants were allowed to be part of its governance.

It was not only the paper records of his post-retirement work that had been purged. So, too, it would appear is his memory of some significant work he did for them in that period.  He shook his head at Bruce Johnston's questions about the affidavits he signed in 2004 to support Imperial Tobacco's defence in the Knight and Sparkes cases.  "I am afraid I don’t believe so. I don’t recall."  

Which is worse? A witness whose memory is so unreliable that he cannot recall the complex task of preparing a legal statement, or the fact that he may have been willing to sign one prepared by lawyers?

Let the record show

Mr. Johnston had with him a stack of documents that he used to contrast Mr. Liston's testimony this week and his consultancy reports to the industry with material he had once put his name to when working with Health Canada.

One of the first he showed Mr. Liston was his advice given to the CTMC that roundly criticized the facts cited in anti-smoking ads prepared by Health Canada in the fall of 1994. (Exhibit 1651).

(You'd have to have a long memory to recall the ads in question - they were the first and final wave of anti-smoking campaigns financed by the Tobacco Demand Reduction Strategy to offset the effects of the 1994 tax-roll back. The first of these ads showed a man's hand squeezing a box of cigarettes while the gooey tar dripped into a glass beneath. The second showed smoke in a home and warned of the ear infections, bronchitis and increased risk of SIDS that could result.)

In this memo, Mr. Liston had provided the companies with talking points to counter these ads: - the chemicals in tar were the same as those found in vegetables or nuts.  "Cigarette smoke is not lethal." Health Canada's estimates of mortality is "ill founded and reflect bias but not fact." Second hand smoke levels are so low in homes that it is difficult if not impossible to measure.

He bristled a bit at the suggestion that his criticisms of Health Canada's ads reflected a change in his desire to ensure "health protection."  If his advice to the companies was different than the advice he had once given the Minister of Health it was because his knowledge had advanced. "At the time, whatever I forwarded was because it thought it was accurate. I found out later that it was less than totally accurate."

The plaintiff lawyers looked at each other in disbelief as Mr. Liston revealed that - 50 years after the government officially acknowledged causation - their former ADM of Health did not.

"I did not believe it. Epidemiology gives you associations and they don’t speak to cause, they only speak to frequencies of occurrence. The classic example is to say most people who die have grey hair, but grey hair does not cause death. An association is not causal."

Duty to warn? Right to exaggerate!

His answers to questions about the obligations on manufacturers to provide factual information to their clients was equally chilling -- especially coming from a man once responsible for overseeing the promotion of products Canadians put on or in their bodies.

"Generally I would say there are many cases where exaggeration is used as a way of promoting use and sale. The whole cosmetic industry is predicated on that - some degree of latitude is granted in the form of exaggeration."  

Mr. Liston seemed to feel that the absence of any reference to risks in cigarette advertising did not mean that there was any misleading about the existence of risk. "I am not sure that they spoke to the risk of smoking in any of their ads."

The purpose of cigarette advertising, he said, was "to try to get market share." He acknowledged that advertising might also encourage use, even for tobacco ads, but this was not a reason to ban it.

Bruce Johnston: "Does tobacco advertising encourage people to participate in an unsafe or dangerous practice?"
Albert Liston: "I have difficulty with that because you can smoke and it doesn’t kill you. Is the practice dangerous? Statistically speaking, over a number of years and thousands of cases it does impact on the number of years of life lost. Is it a dangerous practice? yes, but the manner I which you are framing it leaves me with some concern. 

Bruce Johnston: "Because it doesn’t kill everyone?"
Albert Liston: "Amen!"

Not in line with other scientists -

A recurring theme in Mr. Liston's testimony was the extent to which he saw his own scientific conclusions as being above those of his colleagues - whether those were colleagues in other branches of Health Canada or in health authorities in other areas.

* He refused to back down from his assertion that the switch to the term "addiction" was one supported by the broad scientific community, even after being shown the many-layered peer review process behind the 1988 Surgeon General Report, or the conclusion of the industry's own expert historian that by the late 1980s the term addiction had been accepted by nationally-recognized expert committees in Canada and the United States.

* He pooh-poohed the 1986 Statement of the World Health Assembly that smokers should be warned of the addictive nature of smoking, even though he had been part of the chain within Health Canada that had recommended support for this position. (Exhibit 40346.371)

* He could not recall the existence of the Dominion Council of Health (an important advisory body to the Minister of Health that was in place for the first decade of Mr. Liston's career at Health Canada), nor its 1962 acknowledgement of the addictiveness of smoking. (Exhibit 40346.381)

- and not in line with his own department. 

Mr. Liston had testified yesterday that it was not because of any transgressions by the companies against their advertising code that the government moved towards a ban on advertising. (He had left the implication that it was a purely political decision of Minister Epp and had resulted from pressure by advocacy groups).

Mr. Johnston showed a series of documents reflecting high level concerns of the branch about marketing , and a desire to move towards stronger legislative measures in response. Even the CTMC had noted that Mr. Liston had expressed concerns about violations in their meeting with him in April 1986 (Exhibit 274)


Exhibit 1655
Widespread breaches of the code had come to public attention in 1986 after the Non-Smokers' Rights Association assembled a report, and publicized the report in an advertisement in Macleans. (Exhibit 1655)

This focused the attention of Health Canada - both in Mr. Liston's Health Protection Branch, and also in the Policy and Planning and other divisions.

The Deputy Minister, Mr. David Kirkwood, recommended a series of actions to the Minister, Jake Epp - reassuring the NSRA that a ban on advertising is being contemplated,  acknowleding in the media that violations have taken place, hinting that advertising would be regulated -- and doing all of this quickly to "achieve maximum effect in increasing public support for additional initiatives."(Exhibit 1653).

Almost 30 years on, Mr. Liston remained sniffy about his colleagues who had prepared these recommendations. Their jobs were focused on the "social impact" he said in a derisive tone. In those departments "There was a greater probability that there could have been some looser use of terminology."

His slagging of the other parts of the department drew a stunned question from the judge. Was Mr. Liston suggesting that the Minister of Health would receive advice from senior officials to go public with statements that were not based on facts?  Mr. Liston retreated behind the lack of objective information, but did not change his assessment of his colleagues' judgement. "The code is not very specific. One person could subjectively say there is a violation."

Mr. Johnston showed that other contemporaries had expressed concerns about violations of the code - including the previous Minister of Health, Monique Bégin. (Exhibit 1656).

He showed that, contrary to Mr. Liston's view, the CTMC voluntary code had been modified without consultation with Health Canada, and that this had been identified as problematic. (Exhibit 1656.1, 1657)
One change that happened during this period was a change by the Canadian Advertising Foundation to specifically permit the advertising of dangerous products, as long as they were legal for sale. (Exhibit 1658, 1658.1, 1659).

Taking the piss with  Imperial Tobacco's defence team

One of the funniest moments of the trial was too much of an injoke to be appreciated by Mr. Liston, but was not lost on those in the audience who had a good laugh as sparks began to fly between the opposing sides of the courtroom.

It turns out that a one of the many Canadians who wrote asking for stronger laws against tobacco advertising was a Nancy Roberts of 14 Chatsworth Drive in Toronto.

In November 1985 she wrote the Minister of Health, then Jake Epp:  "As someone who at one time was a heavy smoker, I have first hand knowledge of the terrible effects of cigarettes and the difficulties in quitting. I find it appalling that, in as much as cigarettes are unquestionably harmful, the RJ Macdonald company, with the help of J. Walter Thompson, have now targeted teenagers as a desirable market group." (Exhibit 1649.1 )

The reply - prepared by Mr. Liston's staff and transmitted to the Minister's office through his office -- admitted that the ad was a "contravention of rule #7 of the voluntary cigarette advertising code." (Exhibit 1649)

Nancy Roberts
the Lawyer
There was a flurry of objections to this document being filed! Mr. Johnston's tongue was not very firmly in his cheek when he suggested that if Mr. Liston was not considered the appropriate witness to file the document, there might be someone else available.

Left unsaid - but well understood to the rest of us - was that the Ms. Nancy Roberts who wrote the letter in 1985 might be the one and the same as the Nancy Roberts who became a lawyer ten years later and who has subsequently billed many hours to Imperial Tobacco.

Ms. Roberts was not in the court-room this afternoon, but this did not seem to prevent her from knowing what was going on. Mid-afternoon, her colleague Suzanne Côté came in to express her outrage at any implication that they were the same Nancy Roberts. She asked Justice Riordan to "strike from the record that insinuation that it looks similar to her signature."

Justice Riordan laughed. "I didn't connect it with her," he said. But in any event, there was nothing he could do about the transcript. "Maitre Côté, if you tell me that Maitre Roberts said to you that it is not her signature, then, in my mind, it is not her signature."

But will the real Ms. Nancy Roberts please stand up?

On Monday and Tuesday next week, the trial moves to Vancouver where the testimony of UBC professor James Hogg will be video-conferenced.  On Wednesday, the trial will not sit. On Thursday, Mr. Robert Robitaille will testify.

Day 193: Protecting Canadians from gobbledygook

I felt some excitement this morning at the Montreal tobacco trials. The witness today was Mr. Bert Liston, a man who was once in charge of the health protection of Canadians butwho subsequently aligned himself with the tobacco companies.

Mr. Liston is the third official from Health Canada who has been called to testify during the "Defence proof"  - the others were Marc Lalonde and Denis Choinière. He is, however, the only one of these men who has ever worked under contract to the companies.

From the time he received his PhD in stereochemistry from the University of Montreal in 1964 until his retirement from Health Canada in 1992, Mr. Liston worked entirely within the regulatory science department that was then known as the Health Protection Branch.

For the last 8 years of his public service career he was Assistant Deputy Minister - on the organization chart there was only one person between him and the Minister of Health, and about 2,400 positions that reported under his authority.

Mr. Liston would have managed many challenging files -- medical devices like breast implants, a blood supply that proved to be contaminated, pesticides, food safety -- and tobacco regulation.  It was during his tenure at the top of that branch that Health Canada introduced the first legislative and regulatory controls on tobacco products. And it was in defence of those laws that Mr. Liston testified 24 years ago before a different judge of the Quebec Superior Court.

Mr. Liston no longer testifies against tobacco companies, but has testified on their behalf on at least three previous occasions.

In 2004, he helped Imperial Tobacco against an unsuccessful attempt for a class action on light cigarettes in Newfoundland, and against a successful one in British Columbia. Four years earlier, he had testified on their behalf in a suburban Toronto small claims court during the attempt of Joseph Battaglia to claim damages and an apology for having been misled about the level of nicotine in Matinée cigarettes.

It was in connection with that earlier appearance that I had first met Mr. Liston. Twelve years later, he is now much older. Not only in his age (80 years), but also in his slow movements, fading voice and tendency to answer the question he thought he heard rather than the one he was asked. (If he has hearing aids, he did not wear them to court).

There was also an air of self-protection to his answers that I associate with men who have been sidelined by age - like a member of the Legion whose understanding of global conflict has failed to move past the era of their demobilization.

A brief reunion 

It was Ms. Deborah Glendinning who had questioned Mr. Liston during the Battaglia case, and it was Ms. Glendinning who was at the front of the court prepared to do so again this morning. She has not been seen in this court for 3 months, but no one seemed to think to welcome her back.

She began by asking Mr. Liston to talk about his work as a consultant to the tobacco companies, and giving him an opportunity to say that the insights and advice he gave never entered into the area of lobbying. Later, he sad that about 15% of his consultancy work had been for the tobacco companies. And no, he had never lobbied government on behalf of the tobacco industry. (His CV is at Exhibit 21041)

There was a surprisingly short set of questions prepared for this witness, and the plaintiffs were surprised that her questions wound up before noon. Of the 60 or more exhibits quickly entered before he began testifying (They will be numbered from 20974 to 21041), only a handful were actually shown to Mr. Liston.

Can't quit? Change how you smoke - and what you smoke

When asked to explain what the Health Canada's policy on tobacco was, Mr. Liston said that both before and during his time there "the health department was advising Canadians to not smoke," but that "if they were unable to stop smoking [they should] try and reduce their exposure by modifying their smoking behaviour."

He did not, at this point, identify the low-tar brands that have been the focus of so much discussion in this trial, but mentioned ways that smokers could change their smoking behaviour. "In other words don’t take as many puffs, don’t take as deep a puff, throw a way a longer butt, don’t smoke down to the very last bit."

It was only when Ms. Glendinning asked directly that Mr. Liston agreed that Health Canada "always carried that message" that low tar and nicotine products are less hazardous. "They very much asked Canadians to modify their choices to go to the lower tar and nicotine and carbon monoxide cigarettes."

The choice to smoke

Mr Liston was shown a 1973 press release that encouraged smokers to see that lung cancer and heart disease were both "often diseases of choice. It is up to the smoker to avoid them." 

His answer was an unusual admission from someone who had carried such a high level responsibility to protect health. He said that "each individual is responsible for the food they eat, the cigarettes they smoke, the drugs they take." 

A good relationship and a responsive industry 

Mr. Liston saw the relationship between the department and the companies as "a respectful relationship, a business relationship," similar to those he had experienced between the department and food, drug, medical device and other regulated industries.

On the specific example of the government's request for the companies to lower the average amount of tar, nicotine and carbon monoxide in their products, Mr. Liston said that "in the main [the companies] cooperated and were able to bring the levels within the targets."  One reason for the high level of compliance, he suggested, was the threat of regulations.

He said the industry had complied with the requests made of them by Minister Jake Epp, whom he described as taking a more forceful stance with the companies. But even when that force came in the form of legislation, Mr. Liston said it "was not because of any transgression by the tobacco industry."

The Minister over-ruled the scientists.

Mr. Liston made a clear distinction between the scientific work of his branch and the "social" approach of other areas of the department, and the "political" decisions of the ministers office.

"The Health Protection Branch was the scientific regulatory focal point within the department. It was our view within that branch that we provided unbiased scientific information and any recommendation based on science. ... It was incumbent on us to try to provide unbiased information because the Minister had a number of staff people who would look at the political ramifications of what was coming forward  - he would make a recommendation on whether he wanted to accept straight science or modify it."

"We did not to want to move away from that to go into what was deemed to be more politically acceptable – it was strictly speaking the science. Any other modifications would be done by the Minister."

Which is why a tobacco law was passed

Mr. Liston said that before 1988 there was pressure from advocacy groups , but that his branch had not seen the need for more stringent regulations on tobacco products. In 1983 the department decided against bans on advertising,(Exhibit 20980, 20981). It was "a political decision on the part of a minister" that led to a more formal regulatory approach. (The Tobacco Products Control Act was passed in 1988). 

He cited two reasons he thought a law was not necessary. 

"We were getting what we wanted from the industry. The other factor was that other countries had gone forward with more aggressive programs and in some cases with advertising bans and these were not found to be very effective. Smoking uptake in those countries did not drop as a result of a ban on advertising. There was some thought that it was not an effective procedure or process."

The government's duty to warn and to provide some information ...

The term "duty to warn" is not discussed in this trial as much as one might think. Few witnesses have spoken about this responsibility - and Mr. Liston is the second former health official to agree with a tobacco industry lawyer that this is a duty is born by government. (The first was former Health Minister, Marc Lalonde.)

The first warnings appeared on Canadian cigarettes in 1972. Mr. Liston said that at that time there was it was a "widely known fact" that smoking was dangerous. The reason for the warning, he said was "to reinforce it. It was through repetition that we were hoping to get behaviour modification - to drive home the point of the hazard and to get people to move away from smoking."

"There were limitations, of course that we had to be conscious of - the manufacturers had certain rights to their labels."

Don't confuse smokers with too much information

Mr. Liston did not agree that more information about the toxic contents of tobacco smoke should be communicated to smokers. (Exhibit 20991,20992) 

"Extensive labelling of toxic agents in smoke would not be usable information," he said. Too much information was "not useful and counter productive." 
"People will say 'I don’t know what all this gobbledygook is about.'"

... and don't tell them they are addicted

After the U.S. Surgeon General's 1988 report was focused on addiction, and Mr. Liston fought back against the use of the word "addiction" in relation to smoking. (Exhibit 40001, 40346.373, 40346.381) It is a position he defended today.

He said that there were many who supported his view that this was an inappropriate word to use, and that it was better for smokers to speak of dependence, or habituation. 

"The term 'addiction' brought forward the idea of people that were incapable of functioning in society in a satisfactory way because of the sweats or withdrawal symptoms, and also the needs to find funds to nurture that addiction. A lot of addicts were criminals. This connotation of addiction was troublesome. the medical community went instead to the term that did not have that connotation associated with it."

"Dependence was a better way of describing the way that people would become attached to their smoking habit. Addiction was not the term that we wanted to use." 
He also said it would be better for the government to avoid the term addiction as it "would call into question the integrity of the department." 

"There is a potential element of concern that Health Canada would be allowing the sale of addictive products in the open market and that could have some ramifications."  He saw problems in a "divergence" between the laws that controlled addictive nicotine and addictive narcotics.
Hoist with his own petard

Mr. Liston added some new details to the now familiar story of the Royal Society Report which recommended that the Canadian government use the term addiction with respect to smoking. It turns out the study was commissioned by Mr. Liston in the expectation that the opposite conclusion would be reached.

He thought the report would help stave off pressure that had been built as a result of the "very strong case" built by Surgeon General Koop, which Mr. Liston derided as being "based on his own personal views". 

"I was interested in trying to provide the minister with evidence from a credible professional society that ... we should  use the term other than addiction. I wanted the support of the Royal Society to provide coverage for the Minister. ... I expected them to come back and say 'dependence' or 'habituation' would be the way to go. That was my expectation."
It was not to be. In the fall of 1989, Minister Perrin Beatty received a briefing about the Royal Society's conclusions and gave a handwritten direction to the Deputy Minister: “As a result of this report, I strongly favour the proposed warning on packages.” (Exhibit 20987) 

It took another 5 years and 2 ministers before such a warning was required by regulation. Mr. Liston suggested that the time might have been required to allow the companies to adjust their packaging. 

Although he accepted the decision of the Minister, he never agreed with it. And nor, he said, did others who reported to him. (Exhibit 20988). 
Tomorrow, the fun continues. Mr. Liston's cross-examination is expected to take much of the day. On Monday, part of the trial moves to Vancouver to allow for the testimony of UBC researcher, Dr. James Hogg.
