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.

Australia’s TGA Places Nicotine Pouches Under Therapeutic Goods Rules From July 24, Blocking Imports of Unapproved Products
Australia’s TGA Places Nicotine Pouches Under Therapeutic Goods Rules From July 24, Blocking Imports of Unapproved Products
Australia is strengthening controls on nicotine pouches under its existing therapeutic goods regulatory framework. According to the Therapeutic Goods Administration (TGA), nicotine pouch products must meet regulatory requirements, and unapproved products cannot be legally imported. The move follows Australia’s broader approach of maintaining strict oversight of nicotine products, including nicotine-containing vapes. As nicotine pouches expand globally, Australia’s regulatory approach highlights growing differences in how countries manage emerging smoke-free nicotine products.

China Tobacco Zhejiang files patent for pressure-triggered, on-demand oral nicotine release
China Tobacco Zhejiang files patent for pressure-triggered, on-demand oral nicotine release
China Tobacco Zhejiang Industrial Co., Ltd. has filed a patent application for an oral nicotine delivery product designed to let users actively adjust nicotine release. The product embeds two types of nicotine reservoirs with different wall thicknesses and positions inside a deformable matrix. Pressure applied with the tongue or lips can rupture the reservoirs and accelerate nicotine release. In simulated oral tests, several patent examples showed sharply higher peak nicotine release rates as applied force increased from 0 N to 1 N and 3 N. The filing explores a shift from preset release profiles toward user-triggered nicotine delivery.

BAT New Categories Revenue Rises 18% in H1 2026 as Broad Portfolio Offers More Ways to Win—and Lose
British American Tobacco’s New Category revenue rose 18% at constant rates in the first half of 2026. Nicotine-pouch brand Velo expanded rapidly, while Vuse recovered as U.S. enforcement against illicit e-vapor products strengthened. Heated-tobacco platform glo remained under pressure, and cigarettes continued to provide most of the group’s profit and cash. Compared with PMI and JT, BAT has more routes to growth—but also greater regulatory, investment and execution risks across its broader portfolio.

Smoore Seeks to Toss CCELL Price-Fixing Claim as Court Weighs Vertical Distribution Versus Horizontal Conspiracy
Smoore and four authorized U.S. CCELL distributors are asking a California federal court to permanently dismiss a core antitrust claim brought by direct purchasers. Plaintiffs allege that Smoore coordinated minimum wholesale prices, customer allocation and limits on price competition among distributors, amounting to a per se unlawful horizontal conspiracy. The defendants say the alleged conduct reflects ordinary vertical relationships between a manufacturer and its distributors. The court previously dismissed a similar claim, and the latest dispute centers on whether the second amended complaint adds sufficient facts to establish a horizontal agreement.

Germany Probes 7.6 Million Illegal Vape Case With Estimated €33.3 Million Tax Loss; Four Chinese Manufacturer Employees Under Investigation, Some Packaging in Enforcement Images Resembles FUMOT Products
Germany Probes 7.6 Million Illegal Vape Case With Estimated €33.3 Million Tax Loss; Four Chinese Manufacturer Employees Under Investigation, Some Packaging in Enforcement Images Resembles FUMOT Products
German prosecutors and customs authorities are conducting a criminal investigation into an alleged cross-border organised vape network. Authorities say that between January 2024 and March 2025, four employees of an unnamed Chinese e-cigarette manufacturer allegedly built a network of sales agents and wholesalers that brought more than 7.6 million nicotine disposable vapes into Germany, causing an estimated €33.3 million in excise-tax losses. The manufacturer has not been named. Some products visible in enforcement images have packaging resembling products from FUMOT’s portfolio. European regulatory records from 2024, FUMOT’s public overseas-sales materials and records involving German vape importer and distribution company Zamu-Pro GmbH also show FUMOT/RandM products and German distribution activity during the period covered by the investigation.
