The World Health Organization on Wednesday warned that the widespread availability of inexpensive sugary drinks and alcohol is driving avoidable illness and deaths and straining health systems around the world, with low- and middle-income countries in Africa among the most exposed. In two new reports accompanying the agency’s statement, WHO officials said weak tax systems that fail to raise prices on harmful products leave them affordable and fuel a growing tide of noncommunicable diseases.
“By increasing taxes on products like tobacco, sugary drinks, and alcohol, governments can reduce harmful consumption and unlock funds for vital health services,” WHO Director-General Tedros Adhanom Ghebreyesus said. The statement underlines the dual role that taxes can play: changing consumer behaviour and generating revenue to shore up underfunded health programmes.

The WHO’s advisory comes amid a familiar public‑health dilemma. Excessive intake of sugar and alcohol contributes to obesity, Type 2 diabetes, dental caries and other chronic conditions — and the organization’s reports stress that these illnesses are preventable. At the same time, many countries lack fiscal measures robust enough to raise prices or to direct new resources toward prevention, treatment and health-system resilience.
The policy prescription is straightforward in principle but politically complex in practice. Higher excise taxes and other fiscal instruments make harmful products less affordable, which tends to reduce consumption, while producing a predictable stream of government revenue. For countries confronting fragile public finances and rising treatment costs for chronic diseases, the fiscal case for such taxes has particular force: revenue collected can be earmarked for primary care, vaccination, screening and other services that blunt the long‑term costs of noncommunicable illnesses.
Yet implementation barriers are real. Many African countries and other low‑income jurisdictions face weak tax administration, porous borders, and informal markets that blunt the impact of formal levies. Producers and distributors of sugary drinks and alcoholic beverages often lobby strongly against steep taxes, and marketing campaigns can limit the perceived urgency of policy action. Policymakers must also grapple with concerns that consumption taxes are regressive, hitting lower‑income households proportionally harder.
Those concerns are surmountable when measures are designed with equity and effectiveness in mind. Experience from multiple jurisdictions shows several complementary design principles:
- Set excise taxes at levels that meaningfully raise retail prices and index them to inflation to prevent erosion of real value.
- Apply broad coverage to limit substitution effects and clamp down on tax avoidance through informal or illicit supply chains.
- Earmark a share of revenues for targeted health and social programmes, including subsidies for healthy foods and expanded primary‑care services.
- Pair fiscal measures with regulatory steps — clearer labeling, restrictions on marketing to children and public education campaigns — to amplify behavior change.
For countries with fragile tax collection systems, international support and regional cooperation can help. Technical assistance to modernize customs and excise administration, coordinated fiscal policies across neighboring states, and capacity building for health ministries will magnify the effectiveness of domestic tax reforms. Donors and multilateral institutions can assist by financing the up-front costs of reforms and by supporting surveillance systems that track consumption, revenue and health outcomes.
Political will is the decisive variable. Where elected leaders have committed to tackling tobacco and sugar consumption, they have won measurable improvements in public health and raised resources that feed back into health services. Where political resolve is weak, industry pressure and short‑term electoral calculations can stall action, even as treatment costs compound and preventive services remain underfunded.
The WHO reports make a blunt point: ignoring fiscal policy is not a neutral choice. Allowing harmful products to remain cheap is, effectively, a subsidy for future illness. The alternative — progressive, well‑designed taxes combined with investments in health systems and equitable safety nets — offers a path to fewer cases of diabetes and dental disease, stronger primary care and a more sustainable fiscal footing for health spending.
Policymakers in Africa and elsewhere face a practical question as the next budget cycles approach: will they treat taxation on sugary drinks, alcohol and tobacco as a revenue opportunity to be captured and deployed for health, or as a political minefield to be avoided? The WHO’s message is clear: the choice has consequences for public health and for the financial viability of health systems already under strain.
Raising taxes is not a silver bullet. But when paired with strong administration, equity protections and regulatory measures, it is one of the most direct levers governments possess to reduce preventable illness and unlock funds for lifesaving services — a test of whether health policy will finally match the magnitude of the noncommunicable‑disease challenge.
