The Latest Fear Campaign: Why Julian Hill’s “Vaping is Linked to Cancer” Claim Misleads Australians

Another day, another alarmist claim from Julian Hill on X.

The now familiar line “vaping is linked to cancer” is designed to provoke fear, justify prohibition, and reinforce the Australian Government’s punitive anti-vaping agenda. It is a statement crafted for headlines, not for scientific scrutiny.

The problem is that this claim is deeply misleading.

It takes laboratory speculation, biomarker association studies, and theoretical risk models and presents them as established real-world proof that vaping causes cancer in humans. That leap is not supported by the evidence.

This is exactly the kind of distortion that has poisoned Australia’s vaping debate for years: exaggerate uncertainty into certainty, amplify hypothetical harms, and ignore the overwhelming comparative evidence showing vaping is substantially less harmful than smoking.

A recent example of this distortion can be seen in the reaction to a qualitative risk assessment published through the Science Media Centre examining the theoretical carcinogenicity of e-cigarettes. The assessment itself did not establish that vaping causes cancer in humans. Instead, it attempted to model possible long term risks based on limited toxicological evidence, assumptions about exposure, and mechanistic plausibility. Several experts responding to the publication acknowledged significant uncertainty and stressed that the evidence remains incomplete. Importantly, even within this cautious framework, the discussion centred on hypothetical risk rather than demonstrated real world cancer outcomes. This is a crucial distinction that is often lost when politicians and activists seize upon such studies to claim vaping is “linked to cancer.” A qualitative risk assessment is not epidemiological proof. It is a speculative exercise intended to identify areas for further research. Presenting this as conclusive evidence of cancer causation is scientifically dishonest. It again reflects a pattern in Australia’s vaping debate where preliminary modelling and theoretical concerns are elevated into definitive public health warnings, while the far stronger evidence showing that vaping exposes users to dramatically fewer carcinogens than combustible tobacco is downplayed or ignored.

If Julian Hill is serious about public health, he should be engaging honestly with the evidence instead of repeating simplistic slogans.

The facts tell a very different story.

Cigarette smoking is conclusively linked to cancer because we have decades of epidemiological evidence following millions of smokers over long periods. Smoking-related cancers are caused by exposure to thousands of combustion-generated toxicants, including dozens of established carcinogens such as tar, benzene, formaldehyde, arsenic and nitrosamines.

Vaping does not involve combustion.

That distinction matters enormously.

Because there is no burning tobacco, users are not exposed to the same concentrations of carcinogenic compounds found in cigarette smoke. Numerous independent reviews have found that toxicant exposure from regulated nicotine vaping products is dramatically lower than from combustible cigarettes.

Public Health England concluded vaping is substantially less harmful than smoking.

Cancer Research UK states there is no good evidence that vaping causes cancer.

NHS England advises that while vaping is not risk free, it is far less harmful than smoking and does not produce tar or carbon monoxide.

Even the often-cited laboratory studies used to push “linked to cancer” narratives do not demonstrate actual cancer causation in human vapers.

Many expose isolated cells to unrealistically high concentrations of aerosol condensate.

Others detect biomarkers that may indicate irritation or oxidative stress but do not establish disease outcomes.

Association is not causation.

A cellular stress response observed in a petri dish is not evidence that real-world vaping causes cancer in humans.

This distinction is routinely erased by politicians and activists seeking to manufacture panic.

What makes these claims especially irresponsible is the context in Australia.

The government’s prohibitionist model has already produced clear and measurable harms.

Youth smoking has shown troubling signs of reversal.

The black market has exploded.

Adult smokers face increasing barriers to accessing lower-risk alternatives.

Millions have been spent on enforcement while illicit supply flourishes.

And throughout this failure, officials continue to rely on exaggerated rhetoric rather than transparent evidence.

If cancer risk is the concern, then the rational public health response would be to compare vaping to smoking the behaviour it most often replaces.

That comparison is decisive.

A smoker who completely switches to vaping dramatically reduces exposure to carcinogens.

That is why tobacco harm reduction is endorsed by many international experts and why countries embracing regulated access continue to outperform Australia’s prohibition-first model.

The real danger here is not vaping itself.

It is misinformation.

When public officials falsely imply that vaping carries cancer risks equivalent to smoking, they discourage smokers from switching to a far less harmful alternative.

That misinformation protects cigarette sales, strengthens black markets, and ultimately costs lives.

Australians deserve evidence-based public health communication not fear-based political messaging.

If Julian Hill wants to warn the public about cancer, he should focus on the product responsible for nearly all nicotine-related cancer deaths: combustible tobacco.

Not the lower-risk alternative that could help reduce them.
