When Ideology Speaks Louder Than Evidence: The Tobacco Control Establishment Defends a Failed Model

There was a time when tobacco control was genuinely disruptive. It challenged one of the world’s most powerful industries, exposed decades of deception and forced governments to confront the enormous burden of disease caused by smoking. Through decades of research, advocacy and policy reform, public health experts built an impressive evidence base demonstrating that taxation, advertising restrictions, smoke-free laws and public education campaigns could significantly reduce smoking rates. Millions of lives have undoubtedly been saved because of those efforts, and that legacy deserves recognition.

However, successful movements can develop an unexpected weakness. Strategies that once solved problems can gradually become articles of faith, while policies that were originally driven by evidence begin to be defended regardless of whether the evidence continues to support them. Institutions can become invested in preserving yesterday’s solutions instead of asking whether they remain the most effective answers to today’s problems. Rather than continually testing assumptions against emerging evidence, they begin protecting established narratives. It is a subtle shift, but an important one, because the moment policy becomes insulated from criticism, science risks giving way to ideology.

That appears to be exactly what is happening within sections of tobacco control today. The recent reaction to the possibility of reviewing New Zealand’s tobacco excise demonstrates this perfectly. Before the Cabinet has even considered Associate Health Minister Casey Costello’s proposal, prominent tobacco control academics (Janet Hoek) have publicly condemned the idea, warning that any reduction in tobacco excise would undermine decades of public health progress, increase smoking, encourage youth uptake and hand a victory to the tobacco industry. The message is clear: the policy should not even be questioned.

On the surface, these arguments sound persuasive. They reflect decades of tobacco control messaging and are built upon evidence showing that increasing cigarette prices has historically reduced smoking prevalence. Few serious observers would dispute that tobacco taxation has been an effective public health measure. Price has long been one of the strongest incentives for smokers to quit and one of the most effective deterrents preventing young people from taking up smoking. That historical evidence is real, and it should not be dismissed.

The problem, however, is that history alone cannot determine future policy. Public policy should never become so dependent upon historical success that it stops asking whether circumstances have changed. The nicotine market of 2026 bears little resemblance to the cigarette market of the 1990s. Today, millions of smokers have access to significantly lower-risk nicotine alternatives. Organised criminal groups operate sophisticated international supply chains capable of distributing illicit tobacco on an industrial scale. Consumers purchase products online, communicate through encrypted messaging platforms and access illegal markets with unprecedented ease. These are not minor changes around the edges of the market; they fundamentally alter the environment in which tobacco taxation operates.

Yet despite these profound changes, much of the tobacco control community continues proposing remarkably familiar solutions. Raise tobacco taxes. Reduce the number of retailers. Increase enforcement. Introduce tougher penalties. Expand licensing requirements. Strengthen border controls. Restrict availability even further. The underlying assumption remains that if current policies are not producing the desired outcomes, then the answer must simply be to implement those same policies more aggressively.

Notice what rarely enters the discussion. There is remarkably little willingness to ask whether tobacco taxation itself may be approaching the point of diminishing returns. There is almost no consideration of whether continually increasing prices might eventually encourage unintended consumer behaviour, particularly when organised criminal networks are waiting to supply products at a fraction of the legal price. Instead, criticism of existing policy is often portrayed as criticism of public health itself. The possibility that a policy can be both historically successful and increasingly problematic is rarely entertained.

Perhaps the most revealing aspect of the response from Health Coalition Aotearoa’s Smokefree Expert Advisory Group is not what was said, but what was omitted. Professor Chris Bullen correctly points out that cigarette prices influence smoking behaviour. That is true. Professor Janet Hoek argues that reducing excise would simply trigger a price war with illegal suppliers that governments cannot win. There is truth in that observation as well. Yet neither argument fully engages with the more fundamental question confronting policymakers. What happens when taxation reaches the point where organised crime becomes the most competitive retailer? At what point do increasingly high prices begin creating opportunities that criminal organisations are only too willing to exploit?

These questions are no longer theoretical because Australia has already provided a real-world case study. Over the past decade, Australia has combined some of the highest tobacco prices in the world with increasingly restrictive nicotine policies. The result has not been the elimination of nicotine use. Instead, the country has witnessed the rapid expansion of a multi-billion-dollar illicit tobacco market, widespread criminal infiltration of tobacco distribution, hundreds of firebombings linked to organised crime and billions of dollars in lost excise revenue. Smokers have not simply disappeared. Many have shifted their purchasing from regulated retailers to illegal suppliers.

Faced with this uncomfortable reality, many tobacco control advocates insist that Australia’s experience is somehow unique. According to this argument, Australia’s illicit tobacco crisis reflects organised crime, inadequate enforcement and historical circumstances rather than exceptionally high tobacco prices. But this explanation raises more questions than it answers. Why did organised crime choose tobacco? Why has the illicit market expanded so dramatically in one of the world’s most heavily taxed tobacco markets? Why are criminal syndicates investing so heavily in illegal tobacco if price plays little role in consumer demand? These are entirely legitimate questions, yet they are often dismissed before they are even explored.

This highlights one of the most troubling developments within contemporary tobacco control. Increasingly, disagreement is framed not as a scientific debate but as a question of moral allegiance. Support existing policies, and you are protecting public health. Question whether those policies remain appropriate, and you risk being portrayed as advancing tobacco industry arguments. Such framing may be politically effective, but it is intellectually corrosive because science advances by questioning assumptions rather than defending them. Evidence-based policymaking requires continual reassessment, not unquestioning loyalty to long-established strategies. Policies should ultimately be judged by the outcomes they produce, not by the intentions that originally inspired them.

This is particularly important because nicotine is no longer synonymous with smoking. For most of the twentieth century, that distinction hardly mattered because almost every nicotine user smoked combustible cigarettes. Today, however, smokers have access to vaping products, nicotine pouches and other substantially lower-risk alternatives. This fundamentally changes the policy landscape. The objective should no longer be to make nicotine increasingly inaccessible. The objective should be to make combustible tobacco increasingly obsolete by encouraging smokers to move away from the products that cause almost all smoking-related diseases.

Yet this crucial distinction remains surprisingly absent from much of the current debate. Instead of asking how smokers can most effectively transition away from cigarettes, the discussion continues revolving around making smoking more expensive while paying comparatively little attention to ensuring attractive, regulated alternatives remain accessible. Harm reduction is frequently treated as an uncomfortable exception rather than a central component of modern tobacco control, despite growing international evidence that alternative nicotine products can accelerate smoking decline when properly regulated.

Governments should never fear reviewing established policies. On the contrary, refusing to review them is often far more dangerous. Associate Health Minister Casey Costello has not proposed abolishing tobacco taxation or dismantling tobacco control. She has proposed reviewing whether current excise settings remain appropriate in light of changing market conditions. That is precisely what evidence-based policymaking should involve. Policies should evolve as evidence evolves, and assumptions should be tested rather than protected.

The intensity of the opposition to even conducting such a review suggests something far more significant than disagreement over tax policy. It suggests that, for parts of the tobacco control establishment, tobacco excise has evolved beyond being simply one policy instrument among many. It has become an article of faith, a measure that must be defended regardless of changing evidence or emerging unintended consequences. When questioning policy becomes unacceptable, science ceases to function as an open inquiry and begins resembling ideology. That should concern everyone, regardless of where they stand in the debate over tobacco control, because good public health depends not on defending orthodoxy, but on following the evidence wherever it leads.
