Comparative public health outcomes across countries can provide valuable insight into how regulatory frameworks shape behaviour, risk exposure, and long-term disease burden. A recent comparative analysis of Brazil and New Zealand highlights how differing policy approaches toward nicotine products are associated with divergent trends in smoking prevalence.
Both countries have implemented strong tobacco control measures over the past decades. However, their regulatory treatment of non-combustible nicotine alternatives differs significantly. This divergence offers an opportunity to examine how policy design may influence smoking reduction trajectories, consumer behaviour, and regulatory effectiveness.
Diverging smoking trends
Over the past decade, both Brazil and New Zealand have reduced smoking prevalence, but at markedly different rates. The report indicates that New Zealand reduced adult daily smoking from 16.4% in 2011 to approximately 6.8% in 2024/25, while Brazil’s rate declined more slowly and has recently increased to around 11.6%.
This widening gap suggests that while traditional tobacco control measures remain important, additional factors may influence the pace of decline. These include product availability, regulatory clarity, and the role of alternative nicotine products within national strategies.
Policy frameworks and regulatory direction
Brazil has largely maintained a traditional tobacco control approach, including taxation, public smoking restrictions, and advertising controls. At the same time, it has implemented prohibitions on several non-combustible nicotine products, including vaping devices and heated tobacco products.
In contrast, New Zealand has incorporated non-combustible alternatives into its broader tobacco control strategy. Regulatory frameworks allow these products to be legally available under defined conditions, including age restrictions, product standards, and controlled retail environments. Public health communication has also played a role in informing adult smokers about alternatives within a regulated context.
These differing approaches reflect two distinct regulatory models: one focused primarily on restriction, and another integrating risk differentiation within policy design.
Market dynamics and enforcement challenges
The report highlights that prohibition does not necessarily eliminate demand. In Brazil, despite regulatory bans, millions of consumers are estimated to use vaping products, with supply largely occurring through informal or illicit channels.
Illicit markets present challenges for regulatory oversight, including the absence of product standards, quality control, and age-verification mechanisms. This can limit the ability of authorities to manage risks effectively and monitor usage patterns.
In contrast, regulated markets provide authorities with tools to set product specifications, enforce compliance, and collect data to inform policy decisions. This distinction is relevant for broader regulatory considerations, particularly in relation to consumer protection and enforcement capacity.
The role of non-combustible alternatives
A central issue in the comparison is how non-combustible nicotine products are positioned within tobacco control strategies. The report notes that such products eliminate combustion, which is the primary source of toxic exposure associated with smoking-related disease.
However, these products are not risk-free and require appropriate regulation. The key policy question is how to balance potential benefits for adult smokers with safeguards to prevent youth uptake and unintended consequences.
New Zealand’s experience suggests that regulatory frameworks incorporating alternative products, combined with public health messaging and enforcement measures, may contribute to accelerated declines in smoking prevalence. At the same time, the long-term population-level impact depends on patterns of use, including switching, dual use, and initiation.
Regulatory gaps and emerging categories
The report also identifies regulatory gaps in Brazil, particularly in relation to newer product categories such as nicotine pouches. The absence of clear frameworks may result in unregulated market activity, limiting oversight and consumer protections.
From a policy perspective, emerging nicotine categories raise similar questions across jurisdictions: how to define product standards, regulate marketing, apply taxation, and ensure proportionate oversight relative to risk.
Implications for evidence-based policy
The comparison between Brazil and New Zealand illustrates the importance of aligning regulatory frameworks with observed consumer behaviour and evolving product landscapes.
Key considerations for policymakers include:
The effectiveness of prohibition versus regulated access
The role of illicit markets in shaping real-world outcomes
The importance of risk-proportionate regulation across product categories
The need for clear communication to support informed decision-making
No single policy model is universally applicable. However, comparative evidence can support more informed, adaptive approaches to nicotine regulation.
Conclusion
Brazil and New Zealand represent two distinct policy pathways within global tobacco control. Both have achieved reductions in smoking, but at different speeds and under different regulatory conditions.
The evidence suggests that regulatory design, particularly how non-combustible alternatives are addressed, may influence outcomes in measurable ways. As new nicotine products continue to emerge, the challenge for policymakers is to develop frameworks that are evidence-based, proportionate, and responsive to real-world behaviour.
A balanced approach that combines strong safeguards with effective regulation and clear public health communication is more likely to support sustained reductions in smoking-related harm.
