Study Suggests Smokers Switching to E-cigarettes Reduce Heart Disease Risk
A new study published in Circulation found that switching to e-cigarettes can lower the risk of heart disease by 34%.

A recent study published in Circulation suggests that switching to e-cigarettes can reduce the risk of developing heart disease by 34% among smokers.


A foreign research team has analyzed data from 32,000 adult tobacco users who participated in the nationally representative Population Assessment of Tobacco and Health (PATH) from 2013 to 2019. The researchers evaluated e-cigarette and smoking patterns and compared them to disease reports and heart disease incidence, including stroke, heart attacks, and heart failure.


According to the data, smokers have a 1.8 times higher risk of developing heart disease compared to non-smokers, while there is no statistically significant difference in the risk for heart disease between e-cigarette users and non-users. The study concludes that there is a significant link between smoking and heart disease, but no significant link between e-cigarettes and heart disease.


On the other hand, a recent study entitled "Tobacco Use Disorders and Cardiovascular Health" found that the use of combustible tobacco products, smokeless tobacco, and nicotine-containing electronic cigarettes all increase the incidence of acute and chronic cardiovascular diseases. The researchers also added that these harmful effects can be relatively quickly reduced after quitting smoking.


As a result, the research team recommends more traditional methods for quitting smoking, such as providing medication treatment, emphasizing counseling for rapidly reducing risk after quitting, and appropriate follow-up.


A study utilizing data collected from 175,000 individuals who participated in the annual national health interview survey between 2014 and 2019 has found that daily use of e-cigarettes is only associated with higher rates of heart attacks among those who also regularly smoke traditional cigarettes. Additionally, no evidence was found to suggest that individuals who exclusively use e-cigarettes and have never smoked traditional cigarettes are at risk for heart attacks.

Special Report | How Capital Is Reassessing the Global Tobacco and Modern Nicotine Industry: Lessons from a New York Forum
Capital is reassessing the global tobacco and modern nicotine industry as heated tobacco, vaping and nicotine pouches reshape demand, profitability and regulation. At the 2026 New Approaches Summit in New York, investors and analysts examined whether smoke-free growth can sustain earnings, how regulation shapes startup value, and whether shareholder engagement can be more effective than divestment. The debate points to a broader shift: tobacco transition is increasingly becoming a capital-allocation, governance and valuation question.

China Tobacco Hubei explores staged nicotine pouch delivery, using dynamic membranes to slow early release and gradient particles to sustain later delivery
China Tobacco Hubei explores staged nicotine pouch delivery, using dynamic membranes to slow early release and gradient particles to sustain later delivery
China Tobacco Hubei Industrial Co., Ltd. disclosed several oral nicotine-related patent applications in August 2026, including two that approach staged nicotine release from different directions. One uses a high-viscosity membrane that forms inside the pouch after contact with saliva to slow rapid early release, while the other uses gradient particles with a faster-disintegrating outer layer and a slower core to create a fast-to-sustained release profile. Together, the filings explore how nicotine pouches could balance initial delivery with release later in use.

U.S. Rep. Raja Krishnamoorthi on Oct. 6 questioned the FDA over its plan to reassess and potentially replace the 2021 PMTA regulatory framework, asking the agency to identify provisions it may change or eliminate, state whether current scientific evidentiary standards will be maintained, and disclose communications with Altria, Reynolds and other parties challenging the rule.

Smoke-Free Business Hits 42% of Q2 Net Revenue as PMI’s First TNFD Report Covers Single-Use Electronics, Critical Raw Materials and IQOS Repairs
Philip Morris International has published its first report aligned with the Taskforce on Nature-related Financial Disclosures, bringing its electronics supply chain and the use and end-of-life stages of smoke-free devices and consumables into its nature-related assessment. PMI said its smoke-free business accounted for about 42% of total net revenues in the second quarter of 2026. The report says non-circular electronic products, particularly single-use items, can increase consumption of limited natural resources and also details an IQOS repair pilot. A 2040 circularity scenario tests assumptions including a 50% reduction in product waste-related costs, 10% raw-material savings and a 25% substitution rate for refurbished products versus new products.
