nav 2: no-reliable-evidence
Big tobacco strongly argues that there is no reliable evidence to show that plain packaging will reduce smoking rates. The tobacco companies have used this argument in their advertising campaigns in Australia, the UK, France and elsewhere. It is part of the opposition in each jurisdiction that considers the policy.
Advertisements run by BAT in Australia and JTI in the UK.
These industry campaigns make bold but simple assertions that are often then picked up and repeated in the media. The tobacco company submissions to the governments go into more detail. Their arguments fall into four broad categories:
The four big tobacco companies have criticized the systematic evidence reviews — such as the Stirling Review, the Chantler Review, and the Hammond Review, detailed on the RESEARCH EVIDENCE page of the Tools and Resources.
For instance, in its response to the UK 2014 consultation, Imperial Tobacco commented on the Chantler Review:
“At its heart the Report relies on a selection of theoretical studies, including those in the ‘Systematic Review’ commissioned by the Department of Health from Public Health Research Consortium (“PHRC”), none of which have been able to show that standardised packaging would reduce smoking prevalence and which themselves have had to acknowledge their very significant limitations.” [p. 9]
In its written response to the Oireachtas Joint Committee on Health and Children in Ireland, JTI stated that:
“The Systematic Reviews, which were written by a small number of tobacco control advocates, are not reliable or convincing. The methodology is flawed. Not a single study can be pointed to in the Systematic Reviews which demonstrates that plain packaging is likely to achieve actual public health benefits. Furthermore, the individual surveys underlying the ‘systematic’ reviews test what people say they will do rather than what they actually do.”[p. 5]
In their responses to consultations on plain packaging, tobacco companies have consistently stated that the real life evidence from Australia’s statistics on prevalence and consumption do not show any decline attributable to plain packaging and that countries should wait until the outcome of real life evidence from Australia.
For instance, in its submission to the UK 2014 consultation, Imperial Tobacco stated:
“The Australian Government is planning to conduct a review on the plain packaging implementation in December 2014 and we would expect other governments to wait until this review has been completed before making any policy decisions.”[p. 21]
And the JTI submission to the Canadian 2016 consultation stated:
“The empirical evidence does not show that plain packaging has accelerated the rate of decline in smoking, or has had any public health impact at all.”[p. 71]
(The Post-Implementation Review by the Australian Government was published in February 2016 and is discussed on the Australia’s Post-Implementation Evidence page of the Tools and Resources.)
In its submission to Australia’s post implementation review of plain packaging, Philip Morris stated that:
“The vast majority of the data available from the first two years of plain packaging show consistently that there is no sound basis today for concluding that plain packaging has been effective in achieving its original objectives of reducing smoking prevalence or consumption.”[p. 12]
The tobacco company consultation submissions also highlight other statistics from Australia to seek to show that prevalence and consumption have not been affected by the introduction of plain packaging.
Philip Morris, in its submission to the Australian Post-Implementation Review, cited the surveys from a number of Australian state governments and organizations.
“. . . four of five states, Victoria, Queensland, Western Australia and South Australia reported increases in smoking prevalence after the implementation of plain packaging. Specifically, smoking prevalence in South Australia increased from 16.7% to 19.4% between 2012 and 2013. During the same period, smoking prevalence in Queensland and Western Australia went from 14.3% to 15.8% and 12.7% to 13%, respectively.” [p. 9]
However, these state surveys use small sample sizes and, therefore, year on year, the changes in prevalence are not statistically significant. This issue was addressed in the PIR (see the Australia’s Post-Implementation Evidence page on Tools and Resources).
The tobacco companies rely on academic studies both to criticize the supporting research evidence and to analyze the prevalence and consumption data from Australia. It is important to note that almost all of these have been directly funded by the tobacco companies, none of them has been subject to peer review, and their authors were never provided access to tobacco company internal research or sales data to assist or verify their conclusions.
It is also important for government officials to recognize the experts that the industry repeatedly use around the world and the criticisms that have been made of them. Reports by the following experts are considered below:
In relation to smoking prevalence and sales data from Australia -
In relation to the international research evidence on plain packaging:
In its response to the Norwegian consultation JTI stated:
“Studies by the Universities of Zurich and Saarland [by Kaul and Wolf] have found that plain packaging has had no effect on smoking prevalence, either among minors or adults.1
A study by London Economics found that: “the data does not demonstrate that there has been a change in smoking prevalence following the introduction of plain packaging and larger health warnings, despite an increase in the notice ability of the new health warnings” 2.
Contrary to misleading claims by the tobacco control lobby, Australian government data further reinforces the fact that plain packaging has not had a positive impact. The overall decline in smoking prevalence between 2010 and 2013 is consistent with the continuation of the pre-existing trend, despite the introduction of plain packaging.” [pp. 11–12]
These two studies have been referred to extensively by all the tobacco companies, in particular those by professors Kaul and Wolf from the Universities of Zurich and Saarland. In their response to the 2014 UK consultation, BAT relied on a Kaul and Wolf study to state:
“The evidence to date from Australia shows that more than 18 months after its introduction, Plain Packaging has not had any effect on smoking behaviours beneficial to public health.3”
The Kaul and Wolf studies are relied on by BAT, JTI, PMI, and Imperial Tobacco in all their consultation submissions.
These (and other industry-commissioned studies) claim that there was an existing downward trend in tobacco prevalence rates in Australia that would have continued even without plain packaging being introduced. A number of tobacco-control measures were introduced in Australia at a similar time to plain packaging, such as larger graphic health warnings and increases in excise tax. The analysis from these studies is that plain packaging did not increase the predicted trend in the rate of decrease in prevalence and, therefore, cannot be shown to have had any impact.
Sinclair Davidson of RMIT University in Australia has been vocal in claiming that consumption rates and sales have not fallen. Philip Morris relies on his reports to claim that there is no evidence to show that plain packaging has had any impact on the declines that have occurred.
“Researchers from RMIT University in Australia who analyzed this data could find no evidence of a plain packaging effect. When holding price constant and controlling for long-term declines in spending on tobacco, the researchers found: ‘Any evidence to suggest that the plain packaging policy has reduced household expenditure on tobacco is simply lacking.’”4
BAT has consistently relied on reports by Professor Kip Viscusi. Following his critical review of the studies supporting the conclusion that plain packaging increases the effectiveness of health warnings, Prof.Viscusi claims there is:
no evidence from these studies that plain packaging will increase the effectiveness of warnings … The public is overwhelmingly aware of the dangers of smoking. In this environment, there is no beneficial role of plain packs for increasing the effectiveness of warnings or discouraging smoking initiation. 5
A report by Professor Mitchell of the University of Virginia is also used by different tobacco companies. His report concludes that:
“Factors associated with the initiation, continuation, and cessation of underage smoking have been the subject of a large amount of empirical research. Two propositions relevant to the question of the effects of standardized packaging regulations on underage smoking are apparent from this body of research: (a) many variables are now known to be associated with underage decisions to initiate and continue smoking; (b) features of cigarette packaging have been relatively little studied as a cause or correlate of underage smoking, with no published field studies demonstrating an association between standardized cigarette packaging characteristics and reduced smoking initiation or continuation by underage persons.”6
The reports by Mitchell and Viscusi were annexed to the BAT submission to the UK 2014 consultation.
JTI relies on a report by Professor Steinberg from 2010 7 that analyzes the research evidence on plain packaging and his letter to the Chantler Review process in 2013, which stated that he was aware of:
no scientific evidence that suggests, nor would [his] understanding of the current research on adolescent decision-making suggest, that cigarette packaging is relevant to adolescents’ decisions to experiment with or continue smoking.
JTI also commissioned reports by Professor Devinney who has undertaken ‘in-depth analysis of a large number of publicly available consumer studies’ on plain packaging. His 2014 report was submitted by JTI to the Chantler review and concluded that:
The current evidence base is insufficient to justify the conclusion that plain packaging is likely to have any impact on actual smoking behaviours. 8
The studies by Kaul and Wolf (which did not receive a peer-review scrutiny before publication) have been the subject of significant academic criticism. A paper by Anthony Laverty and others commented on:
…the low statistical significance of the analytical methods used and the assumption that Standardised Packaging should have an immediate large impact on smoking prevalence
“Both of [the Kaul et al papers] are flawed in conception as well as design but have nonetheless been widely publicised as cautionary tales against standardised pack legislation.”
A study by Diethelm and Farley sought to assess the effect of plain packaging on smoking prevalence among adults in Australia based on the same data as Kaul and Wolf but using a more appropriate statistical method and accounting for the potential effect of other key tobacco-control measures. They concluded that:
A significant decline in smoking prevalence in Australia followed the introduction of plain packaging, after adjusting for the impact of other tobacco control measures. This conclusion is in marked contrast to that of the industry-funded analysis. 10
Cancer Council Victoria have also produced critiques of Karl and Wolf’s reports 11; the London Economics report 12; and the Davidson and de Silva report. 13

Reports by Viscusi, Mitchel, Devinney and Steinberg were used as expert evidence by the four tobacco companies in their legal challenge to the UK plain packaging regulations.The judge was highly critical of the evidence put forward by the tobacco companies in general stating that they “not accord with internationally recognised best practice” or international norms. The judge also highlighted flaws in the reports of specific experts including Viscusi [at paragraph 385], Mitchell [at paragraph 384], Devinney at [at paragraph 388] and Steinberg [at paragraph 353]. 14
The criticisms included that:
Similar criticisms can be made of all the academic experts relied on by the tobacco industry. More detail on the High Court legal challenge against the UK regulations is provided in Legal issues and case summaries.
The Evidence pages of the Tools and Resources contain detailed information about the evidence that supports the introduction of plain packaging of tobacco products.
The judge’s conclusion was that the “qualitative evidence relied upon by the [Government] is cogent, substantial and overwhelmingly one-directional in its conclusion.” [para 492].
He was then scathing in his criticism of the evidence put forward by the tobacco companies because it was not peer reviewed, either ignored or airily dismissed the worldwide research and literature base, and was frequently unverifiable. He made detailed critiques of each of the expert reports put forward by the tobacco companies and concluded that this “body of expert evidence does not accord with internationally recognised best practice.” [para 374].
