Prisons Turn to Vaping for Harm Reduction as Ireland Debates Tougher Restrictions

Irish prison officials are exploring vaping to lower cigarette smoke exposure, highlighting a striking contrast with calls for tougher national restrictions.

As Ireland considers increasingly restrictive vaping policies , including comments from Taoiseach Micheál Martin supporting a potential ban, officials inside the country’s prison setup are examining whether controlled vaping could help solve a very different public-health problem: exposure to cigarette smoke.

The contrast highlights a wider tobacco harm reduction debate.

While vaping is increasingly treated as a regulatory problem outside prison walls, correctional authorities in Ireland, England and Wales are exploring how specially designed products can reduce harms associated with smoking and nicotine dependence.

A prison-specific vape has been credited with helping dramatically reduce deliberate fires without removing the smoke-free nicotine alternative prisoners have relied upon since the estate became smoke-free.

Prisons in England and Wales became smoke-free in 2018 , with vaping, nicotine replacement therapy and cessation backing offered as alternatives.

Vaping proved popular, but created an unexpected security problem.

Instead of responding by banning vaping, HM Prison and Probation Service worked with manufacturer Moja to develop a tamper-resistant Safer Vape Pen.

One submission reported a 92% reduction in vape-related fires, while officials told the House of Lords that the wider initiative contributed to a 46% reduction in overall prison fires.

Only 36 vape-related fires were reported during the first five months of 2026, compared with more than 2,000 previously cited by prison officials.

Concerns about prison officers’ exposure to second-hand cigarette smoke have prompted air-quality investigations and measures including improved ventilation and smoking-cessation support.

Officials have also reportedly explored prison-specific vaping products and tighter control over tobacco availability.

Vaping does not involve combustion, so moving prisoners who smoke completely to vaping would remove cigarette smoke from that source, and vaping indoors raises no serious concerns about aerosol exposure and air quality.

He also called vaping the “revenge of Big Tobacco. Those comments have been challenged by tobacco harm reduction advocates because they do not reflect the current comparative-risk evidence.

The latest Cochrane living systematic review, published in August, found high-certainty evidence that nicotine e-cigarettes assist more people quit smoking than conventional nicotine replacement therapy, including patches and gum.

For every 100 people trying to quit, researchers estimated that approximately eight to ten would succeed with nicotine vaping, compared with around six using NRT.

So while everyone agrees that vaping should not be encouraged among children or individuals who do not smoke, it does mean that describing it as approximately equivalent to—or worse than—cigarette smoking risks obscuring an important distinction for adults trying to leave combustible tobacco behind.

When vaping created a new fire hazard, authorities modified the device.

Ireland could potentially apply the same principle to second-hand smoke: identify the dominant harm, then provide a tightly controlled alternative designed around the environment.

It requires recognising that cigarette smoking and nicotine vaping do not present equivalent risks.

National political rhetoric is moving towards treating vaping more harshly, while prison officials are examining whether the same innovation could assist reduce exposure to cigarette smoke.
