Irish prison officials are exploring vaping to reduce 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 system 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.
The experience in England and Wales is particularly striking. 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.
When England and Wales chose innovation over prohibition
Prisons in England and Wales became smoke-free in 2018, with vaping, nicotine replacement therapy and cessation support offered as alternatives. Vaping proved popular, but created an unexpected security problem. Prisoners could dismantle conventional devices and use their heated coils to ignite fires.
Instead of responding by banning vaping, HM Prison and Probation Service worked with manufacturer Moja to develop a tamper-resistant Safer Vape Pen.
The device is deliberately frangible: attempts to dismantle it to access the heating element cause it to break apart. Parliamentary evidence indicates that vape-related fires subsequently fell sharply. 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. Prisons Minister Lord Timpson consequently told peers he did not believe vaping should be banned in prisons.
The episode offered an unusually practical example of harm reduction: authorities identified an unintended consequence of a lower-risk alternative and redesigned the product rather than removing it.
Vaping to reduce smoking
Meanwhile, Wheatfield Prison in Dublin faces another problem. 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.
The potential benefit is straightforward. Cigarettes burn tobacco and generate second-hand smoke containing combustion-related toxicants. 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.
This distinction matters particularly in an occupational setting where employees cannot simply avoid their workplace.
Ireland’s Prime Minister’s misguided comments
The prison discussion comes shortly after Taoiseach Micheál Martin publicly described vapes as “nearly worse than cigarettes” and indicated personal support for potentially banning them. 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 help 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.
Cochrane also stresses that its findings concern regulated nicotine e-cigarettes. Researchers found no evidence of serious short-term harm, while acknowledging that larger, longer studies are needed to fully assess long-term safety. So while everyone agrees that vaping should not be encouraged among children or people 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.
A demonstration of pragmatic harm reduction
Correctional facilities provide an unusual test of nicotine policy because smoking prevalence and dependence have historically been high while security requirements are far more stringent than in ordinary retail environments. England and Wales demonstrate that these challenges do not necessarily require prohibition. When vaping created a new fire hazard, authorities modified the device. Parliamentary evidence now describes the Safer Vape Pen programme as contributing to substantial reductions in fires, although other fire-prevention measures were introduced simultaneously and the figures should not be interpreted as proving that the vape redesign alone caused the entire decline.
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. That does not require treating vaping as harmless. It requires recognising that cigarette smoking and nicotine vaping do not present equivalent risks.
The apparent contradiction in Ireland is therefore noteworthy. National political rhetoric is moving towards treating vaping more harshly, while prison officials are examining whether the same technology could help reduce exposure to cigarette smoke. For tobacco harm reduction, the prison experience offers a broader lesson: when abstinence is difficult to achieve (as is generally always the case), adapting a lower-risk alternative may sometimes produce better outcomes than simply banning it.
