Switching to E-Cigarettes and Heated Tobacco Products Reduces Vascular Damage and Smoking-Related Illnesses: Study
CoEHAR researchers found using e-cigarettes and heated tobacco products can reduce smoking-related diseases. Their study challenges misconceptions about vaping.

Researchers from the Center of Excellence for the Acceleration of Harm Reduction (CoEHAR) involved in the Replica project have discovered that switching to electronic cigarettes and heated tobacco products can reduce the incidence of vascular damage and smoking-related diseases. The findings challenge the prevailing misconception that using e-cigarettes and heated tobacco products is just as harmful as smoking.


The study has been published by an independent laboratory affiliated with the Replica Project, whose scientists are world leaders in harm reduction. The latest research assessed the damage caused to endothelial cells, which release substances that control the dilation and contraction of blood vessels, by cigarette smoke compared to electronic cigarettes and heated tobacco products.


Damage to the inner lining of blood vessels known as endothelial damage is a primary pathology that leads to diseases such as atherosclerosis, with smoking being the main culprit. Smoking can impair the normal function of the endothelium, cause damage to the vascular system, and lead to the development of high blood pressure and atherosclerosis. Smoking and exposure to smoke toxins are related to the impairment of the repair mechanism needed for endothelial homeostasis, such as the inhibition of endothelial cell migration.


Reducing exposure to smoke toxins may mitigate the harmful effects on endothelial and cardiovascular disease development. Numerous international studies have investigated the impact of smoking on endothelial cell migration and associated vascular damage, particularly a study by Taylor et al. (2017). Compared to cigarette smoke, exposure to electronic cigarette aerosol significantly reduces inhibition of in vitro (in a test tube) endothelial cell migration. This means that endothelial cells exposed to electronic cigarette aerosol retain their ability to effectively heal small wounds in blood vessels, unlike those exposed to cigarette smoke and toxins, which severely limit their wound repair capacity.


One of CoEHAR's most successful projects is the Replica project, in which researchers have replicated some of the most significant international studies in the field of reducing tobacco harm via an independent laboratory network. They have demonstrated a reduction in the toxicity of electronic cigarettes and have established reference standards for scientific research. The goal of CoEHAR's scientists is to conduct a multicenter replication study to validate the results of Taylor and his colleagues.


A study titled "Comparative evaluation of e-cigarette aerosol and cigarette smoke on endothelial cell migration: a replication study" compared the effects of three commercial e-cigarette delivery systems and traditional cigarettes. Following international scientific standards and utilizing the latest technology and tools, the data collected by researchers at CoEHAR confirmed the findings of Taylor and colleagues: e-cigarettes do not induce inhibition of endothelial cell migration in vitro compared to cigarette smoke, thus reducing harm caused by tobacco smoke. Furthermore, CoEHAR researchers compared the results of two different heated tobacco products, which demonstrated significantly less impact than observed with cigarette smoke.


According to Professor Massimo Caruso, co-project leader of the Replica initiative, "As previously demonstrated by the Replica research team, the harm caused by electronic nicotine delivery systems is significantly lower than the harm caused by cigarette smoke. An interesting fact is that using non-combustible products can reduce vascular damage and prevent the likelihood of smoking-related diseases such as atherosclerosis and hypertension. Our research once again challenges the notion that electronic cigarettes or heated tobacco will cause similar damage to combustible cigarettes.

Science | International Experts Propose a New Smoking Cessation Pathway, Citing Higher Quit Rates With E-Cigarettes Than Nicotine Replacement Therapy
Science | International Experts Propose a New Smoking Cessation Pathway, Citing Higher Quit Rates With E-Cigarettes Than Nicotine Replacement Therapy
A new expert paper in JAMA urges U.S. clinicians to include nicotine e-cigarettes in smoking-cessation discussions, citing higher quit rates than nicotine replacement therapy. It also stresses that products must deliver enough nicotine to replace cigarettes, dual use should be brief, and complete switching is the goal. 2Firsts argues the recommendations matter beyond clinics: public-health professionals should reassess relative risk, regulators should preserve sufficient product appeal for adult smokers, and manufacturers should focus on helping users quit cigarettes more sustainably.

Australian Coalition Unveils Illicit Tobacco Plan With 80% Excise Cut and Legal, Taxed Vapes and Nicotine Pouches
Australian Coalition Unveils Illicit Tobacco Plan With 80% Excise Cut and Legal, Taxed Vapes and Nicotine Pouches
Australia’s Coalition has unveiled a national illicit-tobacco policy that would cut tobacco excise by 80% and create legal, regulated and taxed adult markets for vaping products and nicotine pouches if it wins government. The plan proposes an excise of A$0.50 per millilitre of e-liquid and A$0.025 per milligram of nicotine in pouches, alongside A$200 million in additional enforcement and a A$60 million three-year public-awareness campaign. The Coalition says the package would narrow the price advantage of illicit products and undermine organised crime, while Labor and public-health groups warn that dramatically cheaper cigarettes could reverse long-term declines in smoking.

UK PM Andy Burnham Reshapes Vape Retail Rules as Licensing Could Raise Barriers for New Shops
UK Prime Minister Andy Burnham is pushing a high street reform agenda that could give local authorities greater powers over commercial activity, including vape retail. The reforms could involve expanded planning powers and a potential vape retail licensing system, allowing councils to play a larger role in store locations and market access. The measures are part of the UK’s broader shift toward tighter vape regulation, although no nationwide vape retail restrictions have yet been implemented.
