Tobacco taxation policy as part of a wider framework of tobacco control measures

The tobacco taxation proposals were designed as part of a broader strategic programme to reduce the prevalence of NCDs and the associated economic burden. By 2017 there was strong political support to re-orientate the health system and increase collaboration across government departments to develop stronger NCD prevention. Plans to develop chronic disease management were outlined, and in early 2018 a Health Promotion Strategic Framework (HPSF) was developed. This focused on two leading preventable risk factors – smoking and obesity, adopting a ‘whole system’ approach to address environmental influences and enhance health literacy⁵.

Tobacco taxation was among the tobacco control strategies, and a range of important developments had started to happen and to show positive impact in the previous year. A ‘Smoke-Free Government’ (SFG) policy was introduced, creating fully smokefree indoor and outdoor public spaces across a large number of government-owned employment and community sites, and ending the practice of sanctioned ‘smoke breaks’ for all government staff (about 25% of all adults on the island). At the same time, the island’s first smoking cessation support service commenced, providing advice, support and free courses of nicotine replacement therapy, and community social marketing promoted the newly available support to help smokers quit. Concurrently, legislative proposals were being developed to meet the key provisions of FCTC, particularly to strengthen policy on packaging, advertising, and protection from secondhand smoke exposure⁹.

The development of the tobacco taxation proposals took place in this context of strategic focus, high profile policies and service development, and public information and discussion in the media and community about smoking. The political debates about the tax increases reflected themes reported in other countries¹⁰, particularly the role of price in deterring youth from starting to smoke and whether the tax would unfairly penalise smokers on low incomes. Discussions indicated that increasing excise taxes and thereby the price of tobacco as a standalone measure may have been politically unpalatable; whereas the case to increase taxes was reported to have been strengthened by being considered against a backdrop of increased quit support, community quit awareness, and wider policies to reduce and restrict smoking.

The view that the taxation proposals were stronger by being accompanied by wider measures was additionally influenced by a parallel area of NCD prevention: reducing sugar-sweetened beverages (SSBs) consumption. In 2018, the government’s health directorate worked with large importers and retailers of soft drinks to improve supply of sugar-free drinks on the island and undertook social marketing to encourage a shift away from SSBs. This supply/demand initiative was accompanied by increased taxes on sugary drinks. SSB consumption declined and water intake increased¹¹. The combination of the commercial and community measures to support the tax increase was considered to have been key in achieving impact and was cited by policymakers as a further reason to view the tobacco excise proposals positively, as they were supported by wider actions.

Academic–government collaboration to achieve population tobacco control policy

The WHO KH is housed in the Research Unit on the Economics of Excisable Products (REEP), University of Cape Town, South Africa. The KH supports Parties to the FCTC by facilitating training, capacity building, technical assistance and knowledge dissemination in the areas of taxation (Article 6) and illicit trade (Article 15) and is funded by international donor foundations, including Cancer Research UK.

There are seven WHO FCTC Knowledge Hubs globally, each focused on various articles of the FCTC (https://untobaccocontrol.org/intro/). While they mimic elements of civil society organizations, they do not necessarily participate in advocacy activities. The WHO KH provides fact sheets to simplify and make more accessible tobacco taxation and illicit trade related topics. Most KHs also work with country-level policymakers¹².

There are documented reports of academic institutions contributing to the implementation of tobacco control policies in South Africa^13,1414. The capacity of academia in this regard has been largely to provide research support to civil society organisations or provide evidence for advocacy to policymakers¹³.

The credibility of the WHO KH, with an established reputation in tobacco taxation, made it an attractive partner to support the Government of Saint Helena’s desire to develop effective tobacco taxation. This was greatly significant in augmenting policymakers’ confidence that the recommendations were robust and evidence-based. Expertise on specific economic policy areas is not generally available within governments, particularly smaller governments, and so expert, impartial tobaccospecific economics input was seen to add value and complement the government’s strong understanding of the local economy.

The role of modelling

The TETSiM model is a quantitative, tax simulation model designed by researchers at REEP¹. It is a partial equilibrium model used to illustrate what could happen to the average retail price, consumption, and excise tax revenue if excise tax on tobacco products increases, and has been shown to be an accurate predictor of these outcomes¹⁵.

The WHO KH has developed and applied the TETSiM model for many countries. In this case, the model was Saint Helena specific, populated with credible local data from government departments. The model reflected the current tobacco tax structure and level of cigarette consumption. Reflecting the current levels of cigarette consumption in Saint Helena, the model takes into account the consumption of the top three most consumed cigarette brands in the country (L&M, Benson & Hedges, and Brand-555), and allows for differing consumer responses to price changes. Given the uniform, specific tax structure, the model was used to calculate various politically viable tobacco excise tax changes and their probable impact on government revenue, and cigarette consumption and deaths to be avoided. The results from the TETSiM model were valued as evidencebased, reliable, and perhaps most importantly, locally tailored – a crucial consideration for policymakers wishing to ensure their circumstances are reflected.

The primary value of the model was to confirm tangibly, based on data, what could be expected to occur to tobacco consumption, and to forecast what would happen to revenue. While the health impetus was a key driver, it was important to identify a specific level for the taxation increase and show the likely revenue impacts because of this. In the wider Saint Helena economic and political context, whereby increasing government revenue is a priority, it was of major importance to be able to show a level of increase that would both decrease consumption as well as guarantee and even increase government revenue in the short-to-medium term. A policy proposal that would decrease consumption and reduce tobacco excise revenue may have been unlikely to achieve the broad political support required for the policy to pass. Modelling has the added benefit of creating a clear roadmap of the planned policy change, effectively easing some of the uncertainty for manufacturers and sellers of cigarettes and tobacco products.

Several models were initially presented and discussed by the Public Health Committee. It was determined that the second modelled option would be optimal for the island, enabling an important reduction in consumption, while moderating the level of tax increase, to be effective while acceptable to the public. Taxation proposals generally are considered by the island’s Economic Committee and so the proposal first was considered by this body as a tax rather than a health measure and was not supported. As a matter of wider population significance, the case was made that the proposal should receive consideration by the full Council, with opportunity for Members to identify questions and concerns. Following presentation and debate, the proposal was taken to the island’s highest policy body, and after this session members were able to further scrutinise the proposal about its role and potential impacts for the community, with support from the government health directorate. The proposal was presented and discussed at the Executive Committee and was unanimously passed in August 2019 and implemented from October 2019.

The final successful policy proposal, presented in Table 1, had a 13.98% increase in excise tax in 2019, followed by an annual inflationary tax increase of 3.8%, plus an additional 1%.

The model predicts that (given a set of assumptions) by 2023, the government will collect £1.136 million (in 2018 prices) annually as excise revenue. This is an increase from the £0.931 million annual collection. Cigarette consumption will decline substantially, resulting in public health benefits (Table 1). While we observe approximately 11% reduction in cigarette consumption, the reduction in smoking prevalence is only half of this at 5.6% (or 1 percentage point). This is based on the assumption that reduction in consumption is partially driven by smokers quitting but also smokers just decreasing their daily consumption. The proposed policy will result in the avoidance of smoking-related deaths. These are projected relative to the number of births in Saint Helena for context. Over the period of assessment, annual lives saved are equivalent to between 20% and 30% of the number of births in 2018.
