The politics of prevention: why public health depends on bold policies
7 May 2026
Education alone will not curb use of tobacco and other harmful products. Only bold legislation can counter industry power and prevent millions of entirely avoidable deaths.
In many countries, the debate around smoking prevention focuses on personal responsibility – the idea that people simply need to make better choices. Policy debates continue to circle back to personal responsibility, but this overlooks a fundamental truth: our choices are shaped by our environments, and our environments are heavily influenced by outside forces, including for-profit actors whose products contribute to preventable disease. This is misleading, but it is politically convenient. It shifts responsibility away from governments and industries that are profiting from addiction, while individuals are left to bear the cost.
Across the globe, more people die from non‑communicable diseases (including cancer, heart disease and diabetes) than from anything else. Tobacco use is a leading driver of these conditions – it alone kills more than 8 million people every year. The harms of tobacco have been well documented and communicated for decades, so most people know using tobacco shouldn’t be encouraged. The problem is not a lack of awareness or information. The problem is that current systems and structures have allowed harmful industries to operate without adequate constraint, and governments have too often chosen short-term comfort over long-term action.
Legislation is a powerful tool to shape living conditions, and strong, well-designed public health laws can shift population behaviour in ways education alone cannot.
Why legislation matters
The evidence is clear and substantial: population‑level policies (including taxation, advertising restrictions and smoke‑free zone laws) are among the most effective and equitable ways to reduce harm. For example, a 10% increase in the price of tobacco reduces consumption by around 4% in high‑income countries, and by even more in low‑ and middle‑income countries.
Legislative and policy interventions work because they reshape the context in which decisions are made. They reduce exposure to harmful products, limit the reach of marketing and make healthier choices easier.

The UK example: a test of political courage
The UK’s proposal to create a tobacco‑free generation is a striking example of legislation as a structural tool for prevention. This matters because health education has to compete with an industry that continues to invest heavily in marketing, product design and lobbying. Treating smoking as a purely behavioural issue ignores the reality of addiction and shifts responsibility away from the systems that profit from it.
Why education alone is not enough
Even in countries with high health literacy, tobacco companies adapt their strategies, creating new nicotine products and targeting young people in their marketing. This generates a profound power imbalance: people are expected to make healthy choices while being constantly nudged in the opposite direction. And once addiction sets in, the tobacco companies have won. Legislation is far more effective at reducing consumption than education alone, particularly among young people and traditionally underserved populations.

Why has legislation taken this long?
Given what has been known about tobacco for decades, a reasonable question remains: why has legislation like this taken so long? Part of the answer lies in the extraordinary efforts of harmful product industries (as well as tobacco, these include ultra-processed food and alcohol producers) to delay, dilute or derail regulation. Tobacco companies have repeatedly challenged policies through litigation, lobbying and public campaigns designed to frame regulation as an assault on freedom rather than a defence of life.
But delay is also a political choice. Governments have often prioritised avoiding short‑term controversy over long‑term health outcomes, and the cost of these decisions has been measured in lives lost to entirely preventable disease. Successes in tobacco control show that legislation can counteract sophisticated marketing strategies and that policymakers can use the law to prioritise population health.
The broader lesson: unpopular policies save lives
Public health policy is rarely popular at first. Seatbelt laws, now commonplace the world over, were once condemned as government overreach. Today it is almost impossible to argue that requiring people to buckle up was anything other than an act of basic civic responsibility. The same trajectory is visible in tobacco control.
The UK is not alone in confronting this tension head on. Australia has long been a global leader in tobacco control, pioneering plain packaging laws that significantly reduced the appeal of cigarettes and contributed to a decline in the prevalence of smoking. Evaluations show that plain packaging increased the impact of health warnings and reduced brand appeal.
A call for bold, decisive action
Legislation does not eliminate personal agency – it creates the conditions in which healthier choices become the default. As countries face rising rates of preventable disease, the evidence is clear: education must be paired with strong policy, and individual responsibility must be supported by structural safeguards.
The UK’s ambition for tobacco-free generation is a development the world will watch closely. The harms of tobacco are well known. The question that remains is whether governments are willing to risk unpopularity to act boldly on what they know.
