The debate on vaping policy in the United Kingdom is at a critical juncture. A motion to expand indoor smoking restrictions — also called “smoking bans” — to include vaping has, of course, sparked outrage from harm reduction advocates, public health experts and business leaders. Emerging research indicates that restricting access to certain vaping products has unintended consequences, including a potential resurgence in smoking.
Inaccurately lumping vaping with smoking
The government’s proposal would treat vaping in the same way as smoking, across indoor public spaces — workplaces, pubs and clubs, even specialist vape shops. This, critics say, is a fundamental misunderstanding of these products’ risk profile. In fact, public health messaging has been grappling with a fundamental problem for ages: relative risk. Combustible cigarettes continue to be one of the largest preventable causes of death, yet vaping is broadly recognised as a far lower risk option for adult smokers. That distinction disappears when both are regulated the same way.
Experts say the proposed restriction would contribute to a misconception gaining ground among the public — that vaping is just as dangerous as smoking, a belief that has been associated with slower switching rates among smokers.
It is also important to note that several independent assessments — including one by Public Health England (PHE) — have concluded that second-hand vapour poses little risk to those around the user.” This begs a critical question: In the face of very low exposure risk, what is the scientific basis behind expanding smoke-free laws?
Encouraging former smokers to revert to smoking?
The proposal arrives at a moment when advances in driving down smoking rates have been closely linked with greatly reducing accessibility to lower-risk alternatives. A grassroots campaign led by the New Nicotine Alliance reiterates that limiting where people can use vape products may prevent smokers from switching — or, worse still, drive former smokers back to cigarettes. This concern is not theoretical. Research from the University of Bristol, published in PLOS Global Public Health, suggests that such a policy restricting access to certain vaping products could lead to adverse outcomes. And some young adult vapers say they might smoke more cigarettes or relapse to smoking as a result of the UK’s disposable vape ban.
Although many participants reported they would switch to reusable devices, the findings point to an important risk: When barriers are raised for safer alternatives, not all users make a smooth transition. Some default to the most available, even if that is the most damaging choice. For harm reduction advocates, this highlights a key principle: the demand for nicotine does not evaporate when products are banned. On the contrary, behaviour is modified — at times in ways that thwart public health objectives.
Economic costs and no health gains
Additionally, lessons from other regulatory encroachments indicate that overly restrictive policies can create parallel, illegal markets. If legal access is limited, informal supply chains tend to grow to meet demand. The Bristol study hinted at this dynamic, too, with some participants predicting that restrictions might have the opposite effect, driving underground trade in prohibited products. Whereas some thought that enforcing the law could further reduce illegal sales, even this ambiguity highlights how complex consumers’ behaviour tends to be. At the same time, policies that limit the availability or convenience of vaping may inadvertently advantage cigarettes, which are widely available. But it also creates a paradox: the most damaging product is often the one that’s easiest to get and use.
A significant difference in risk that is not being considered
Policies that do not take this gradient seriously risk oversimplifying a problem and potentially making it more difficult to reduce deaths from smoking-related disease. The new Nicotine Alliance’s Save Vaping campaign is calling on policymakers, businesses and the public to get involved in the consultation process. But at stake is not just a particular policy, but something deeper — the overall approach to tobacco control in the UK.
Regulation should be risk-proportionate, evidence-based, and in keeping with the principles of harm reduction. This means acknowledging the role of vaping as a smoking cessation tool through smoking minimisation policies and keeping access to safer alternatives for adult smokers.
It’s time to align policy with science and reality
The trick for policymakers is not to downplay risk, but to put it in its proper perspective. While treating all nicotine products as if they posed the same risks may seem precautionary, it may also have unintended consequences that ultimately kill people.
The UK is at a turning point regarding nicotine regulation. On one side is an increasing body of scientific data supporting harm reduction. On the other hand, a policy approach risks conflating fundamentally disparate products. If the aim is to mitigate smoking-related harm, then access to less hazardous substitutes must continue to be an important part of any strategy.
