#Ireland is neither an established #THR success story nor does it provide evidence that #vaping has failed. It is a transition that has lost momentum. Substitution away from combustibles is notable. Future progress will depend on whether policy enables, rather than obstructs, that process. Read about the emergence of #THR in #Ireland, #SouthKorea and #Estonia in our new Briefing Paper. gsthr.org/resources/briefing…

#SouthKorea shows the potential and limitations of a consumer-driven transition. Increased market share for #HTP coincided with a renewed decline in #smoking, but poly-#nicotine use shows market transformation may not produce complete substitution. Read about the shifts away from #cigarettes taking place in #SouthKorea, #Ireland and #Estonia in our new Briefing Paper. gsthr.org/resources/briefing…

“Evidence from #SouthKorea, #Ireland and #Estonia shows that, when they can, people who #smoke will opt for safer alternatives. But these transitions are not inevitable and can be easily disrupted or reversed. When considering #safernicotineproducts, policymakers should always ask: will this make it easier or harder for adults who #smoke to make the safer choice?” Giorgi Mzhavanadze, GSTHR Economist gsthr.org/media-centre/emerg…

Our latest Briefing Paper considers three countries that show emerging but very different shifts away from #cigarettes: one incomplete, one stalled, and one accelerating. What happens next in #SouthKorea, #Ireland and #Estonia will have implications for our understanding of how #tobaccoharmreduction can be supported, delayed - or blocked.

How can the environmental impact of #vaping devices be reduced? New research by Aylen Van Isseldyk, a scholar of the Tobacco Harm Reduction Scholarship Programme (THRSP), explores vaping waste and looks at how recycling, circular economy approaches and environmental education could help address it. Drawing on experiences from Switzerland and Córdoba, Argentina, the paper also considers how sustainability connects with wider discussions around #harmreduction and #publichealth.
