Prison Vaping Tests Harm Reduction as Ireland Tightens Vape Policy

Irish prison officials have considered using a specially designed vape at Dublin’s Wheatfield Prison to reduce employees’ exposure to second-hand cigarette smoke, even as Ireland’s government pursues tighter restrictions on vaping products.

The proposal followed concerns raised by the Health and Safety Authority about air quality and staff exposure at Wheatfield. According to records obtained under Freedom of Information by the Irish Examiner, nicotine sampling at three locations found levels just 4.1 percent below the occupational exposure limit. Prison officials upgraded ventilation, rolled out smoking-cessation support, reduced the variety of vaping products available, and explored a British vape designed specifically for prisons.

The Irish Prison Service also contacted officials in Britain about their approach. That fits with evidence given to the UK Parliament in June, when His Majesty’s Prison and Probation Service (HMPPS) officials said representatives from Ireland and several other countries had visited to examine prison fire-safety measures and safer vaping products. England and Wales have operated smoke-free prisons for years, with vaping available as one alternative to cigarettes.

Vaping created its own problem there. Prisoners were dismantling ordinary devices to access heating elements that could be used to start fires. HMPPS worked with manufacturer Moja on a tamper-resistant Safer Vape Pen that breaks apart when prisoners attempt to reach the heating element. Evidence submitted to Parliament says vape-related fires fell 92 percent after the program was introduced, while overall prison fires fell 46 percent alongside other fire-prevention measures. The same evidence cautions against treating the vape redesign as the only change affecting fire rates.

At a June 30 House of Lords hearing, officials cited just 36 vape-related fires during the first five months of 2026, down from more than 2,000 annually in each of the previous two years. Prisons Minister Lord Timpson told the committee he did not believe vaping should be banned in prisons, while saying officials should continue reviewing the policy.

Ireland, meanwhile, is moving in a different direction outside prisons. Taoiseach Micheál Martin said on Sept. 8 that he personally supported going further on vaping restrictions and described vapes as “nearly worse than cigarettes.” Ireland’s Public Health (Single-Use Vapes) Act 2026 was signed into law on July 15, with actual sales prohibition taking effect Jan. 24, 2027. The government has also proposed additional restrictions covering vape advertising, retail displays, packaging, and product appearance.

The prison discussion also comes as evidence continues to support vaping as a smoking-cessation option for adults who smoke. An August Cochrane living systematic review found high-certainty evidence that nicotine e-cigarettes produce higher quit rates than nicotine replacement therapy. Cochrane estimated eight to 10 quitters per 100 using nicotine vaping, versus about six using patches or gum, while stressing that longer and larger studies are still needed to fully assess safety.

Prisons are an unusual setting, where officials have to manage nicotine dependence, employee exposure, and security risks simultaneously. The experience in England and Wales shows that authorities can modify vaping products when their design creates a specific custodial risk. Ireland’s Wheatfield discussions show the same technology is also being examined as one possible response to cigarette-smoke exposure.
