The analysis shows that countries fall into four distinct groups. Forty-one countries restrict flavors in neither product, sixteen restrict flavors in both, forty restrict flavored e-cigarettes more strictly than flavored cigarettes, and thirty-nine restrict flavored cigarettes more strictly than e-cigarettes. This uneven patchwork has emerged over the past five years, a period in which the market for flavored tobacco and nicotine products has become increasingly global while policies have fragmented along national lines.

The authors frame the stakes clearly: flavors attract new consumers, help keep existing consumers addicted, and can worsen the negative health effects of smoking. Many of these concerns extend to newer products such as e-cigarettes, but with an added layer of complexity for policymakers, who must weigh differential risks for certain groups within the population.

To explain why countries regulate the two product categories so differently, the researchers classified the observed policy combinations into four distinct approaches and generated several hypotheses about the drivers of global policy variation. In exploring these potential explanations, they found that countries’ political systems, state capacity, and the role of states in the global tobacco economy all correlate with different policies on flavor restrictions for cigarettes and e-cigarettes.

The study’s conclusions emphasize that these structural factors create real barriers to coordinated action. Government capacity, governance type, and a country’s place within the global economy all contribute to countries taking different policy approaches, even though they face a globalized product market and share a common body of current scientific evidence.

The fragmentation persists despite global calls to ban flavored tobacco and nicotine products. According to the authors, policymakers, tobacco control advocates, tobacco industry representatives and other relevant actors remain divided on how such products should be regulated, producing the patchwork of national policies documented in the dataset.

Methodologically, the work is a comparative policy mapping exercise rather than a clinical or experimental study. Its contribution lies in the systematic classification of regulations across a large number of jurisdictions and in the hypotheses it generates about political economy explanations for variation. The correlations the authors report between political systems, state capacity, global tobacco economy roles and policy choices are associations identified through this mapping, not demonstrated causal effects.

As an open access article published on 20 October 2026 and shared early as a peer-reviewed accepted manuscript, the study offers researchers and policymakers a structured baseline for understanding how flavor regulation diverges worldwide, and a starting point for testing the political and economic explanations it proposes.

The research team, led by Ava Vukovic of the University of Belgrade and Guglielmo Campus of the University of Gothenburg and Sapienza Università di Roma, with collaborators in Italy, Switzerland, Germany, Sweden and Chile, identified 129 countries, territories or jurisdictions with documented sugar-sweetened beverage taxes. After applying eligibility criteria, 117 jurisdictions entered the final analysis. According to the study, the unit of analysis was deliberately broad: it included sovereign states as well as territories with independent fiscal authority to implement a tax, in order to capture every independently implemented SSBT-related fiscal policy, regardless of when it was introduced or what its original legislative intent had been.

The documentary analysis produced a strikingly uniform result. None of the SSBT legal texts reviewed included dental caries or oral health as an explicit legal objective. This absence held across every World Health Organization region and every national income category. When the researchers widened the net to related implementation documents — governmental reports, background policy analyses and strategic health plans — the picture improved only marginally. Twenty-two jurisdictions, or 18.80 percent, included oral health or dental caries as an explicit objective, and five jurisdictions, or 4.27 percent, mentioned it as a secondary or collateral benefit of reducing sugar consumption. The remaining 90 jurisdictions, 76.93 percent, contained no documented oral-health reference at all in the material reviewed.

The authors are careful about what this absence does and does not mean. A document coded as “oral health not addressed” denotes the absence of a documented reference in the material reviewed, not proof that oral health was absent from the deliberations that produced the policy. Oral health may have been considered implicitly within broader objectives concerning sugar consumption, nutrition or non-communicable disease prevention. The findings therefore concern documented policy framing rather than the full decision-making process — a distinction that matters for anyone tempted to read the result as evidence of active neglect.

The study's second strand assessed the availability of epidemiological dental caries data, using the Decayed, Missing and Filled Teeth (DMFT) index in 12-year-old children, before and after tax implementation. The 12-year-old age group was chosen because the WHO recommends it as a standard indicator for international oral-health comparisons: most children at this age have a complete permanent dentition, they are still the oldest group attending primary schools in most countries, and they show greater dietary independence from their parents, making them particularly relevant for assessing beverage consumption patterns. The researchers searched PubMed, Scopus and Google Scholar, supplemented by hand searches, backward citation, snowball sampling, the WHO-CAPP Malmö database, and doctoral and master's theses in national languages.

The data-availability picture was lopsided. Among the 117 jurisdictions, eligible age-12 DMFT data were available only before tax implementation for 73 jurisdictions (62.4 percent), both before and after implementation for 25 (21.4 percent), only after implementation for 7 (6.0 percent), and neither before nor after for 12 (10.3 percent). Overall, pre-tax DMFT estimates were far more frequently available than post-tax estimates — 83.8 percent versus 27.4 percent. Only 38 jurisdictions, or 32.48 percent, had DMFT data available both before and after implementation when counted at the jurisdiction level in the abstract’s summary figure. The researchers stress that the presence of data before and after implementation is an indicator of potential evaluative capacity, not evidence that the available data are directly comparable or sufficient for causal policy evaluation, and not evidence of any effect of the taxes themselves.

Regional patterns were pronounced. By contrast, explicit references were concentrated in the WHO Western Pacific Region, where 20 of 21 jurisdictions (95.24 percent) included them, while elsewhere they were almost entirely absent: one jurisdiction in the Region of the Americas, one in South-East Asia, and none in Africa, Europe or the Eastern Mediterranean. The authors suggest this clustering may partly reflect the inclusion of Pacific Island countries, where policy discussions around sugary drinks often explicitly connect sugar consumption with dental disease, obesity, diabetes and health-system financing. They caution that this should be read as a regional policy pattern rather than evidence of independent country-level effects.

Economic context also showed associations, though the authors urge restraint in interpreting them. In a complete-case analysis restricted to the 110 jurisdictions with observed per capita Gross National Income values, median pGNI was USD 3,970 in the explicit-reference group (n = 18), USD 42,130 in the secondary-reference group (n = 5), and USD 2,150 in the oral-health-not-addressed group (n = 87). The distributions differed significantly across the three categories (Kruskal–Wallis H(2) = 7.68, p = 0.022), but the authors emphasize that this ecological association should not be interpreted as evidence that national income determines policy framing, particularly given the small secondary-reference group and the wide dispersion of pGNI values, which ranged from USD 110 to USD 117,160 in the not-addressed group alone. The pattern is also not monotonic: the secondary-reference group had the highest median income but contained only five units.

A historical analysis added a further nuance. The researchers grouped implementation years into three eras — before 2000, 2000–2014 and 2015–2023 — covering 16, 45 and 56 jurisdictions respectively. Explicit oral-health references appeared in 25.0 percent, 22.2 percent and 14.3 percent of units in these periods, and secondary references occurred only in the most recent period, in 8.9 percent of units. The distribution across periods did not differ significantly (Fisher-Freeman-Halton exact test, p = 0.201), so the data did not demonstrate a clear temporal shift toward more frequent explicit oral-health framing in more recently introduced taxes. The authors note an important caveat: the implementation year of a tax is not necessarily the publication year of every policy document reviewed, and older fiscal measures may have been discussed within newer health-policy frameworks later. Many early taxes were general excise or consumption taxes rather than health-oriented interventions — the World Bank database records introduction dates of 1965 for Brazil, 1969 for Niue and 1976 for São Tomé and Príncipe, reflecting when a taxing instrument took effect rather than early health policy. Brazil is illustrative: country-level analyses describe its IPI as a general manufactured-goods levy and conclude the country has no SSB-specific tax, its rate having fallen in 2016 and 2018. Almost one-third of SSB excise taxes worldwide tax unsweetened bottled water at equal or higher rates.

The study’s broader point is about evidence infrastructure rather than tax efficacy. Robust modeling studies have supported SSBTs’ cost-effectiveness in reducing obesity and related non-communicable diseases, and econometric modeling and global reviews suggest fiscal policies on sugary drinks can serve as an effective oral-health strategy, mitigating the burden of dental caries and reducing dental treatment expenditures across diverse healthcare systems. Yet obesity and diabetes outcomes are often monitored through established national surveillance systems, while dental caries data are not, creating what the authors call an evidence asymmetry that may reinforce the exclusion of oral health from future policy considerations. The authors argue that explicitly incorporating oral-health objectives and surveillance indicators into SSBT frameworks — aligning with the WHO Global Strategy on Oral Health and the common risk factor approach to non-communicable disease prevention — would strengthen the accountability, comprehensiveness and public-health value of these policies, particularly in low- and middle-income countries where preventive policies may offer the greatest returns on investment given limited treatment capacity. As the authors state, the study was designed as a global evidence and policy mapping study that documents where the written record and the surveillance data fall short; it does not aim to estimate the causal effect of sugar taxes on dental caries.
