Dry Cough Caused by E-Cigarettes: Expert Warnings
Health experts warn of differences in coughing between e-cigarettes and traditional tobacco, with potential long-term health risks.

According to Russian media "Today Russia," health experts warn that the dry cough caused by e-cigarettes is different from the phlegm-producing cough caused by traditional tobacco. The usage instructions for e-cigarettes also clearly warn about this common phenomenon and specifically caution first-time e-cigarette users who have recently quit traditional tobacco.

 

Experts believe that this may be a sign of the body recovering from years of tobacco smoke. Smoking can damage tiny structures in the airways called cilia, which are designed to clear debris and mucus from the lungs. When irritants linger in the lungs, mucus builds up and the body attempts to clear the airways, leading to "smoker's cough.

 

Professor Leon Shahab, co-director of the Tobacco and Alcohol Research Group at University College London, stated: "Coughing caused by e-cigarettes is a natural response as the body recovers from tobacco use, during which the cilia in the lungs repair and regain functionality. Therefore, if smokers switch to e-cigarettes, similar symptoms may occur.

 

Peter Hajek, a renowned researcher and professor in the field of e-cigarettes at Queen Mary University of London, stated that "e-cigarette cough" typically disappears after a few weeks of use.

 

E-cigarettes allow users to inhale nicotine vapor, which is created by heating e-liquid that typically contains propylene glycol, glycerin, flavorings, and other chemicals. Unlike traditional tobacco, e-cigarettes do not contain tobacco and do not produce tar or carbon monoxide.

 

However, evidence of the potential risks of e-cigarettes is increasing. Multiple studies have raised concerns about the potential harm of e-cigarettes. Last month, an academic study sparked worries about the potential for e-cigarettes to cause cancer.

 

Doctors are concerned about potential lung diseases, dental issues, and even cancer that may arise in the future, affecting individuals who started using e-cigarettes at a young age.

South Korea Extends Vape Rules to Unmanned Stores After Bringing Synthetic Nicotine Under Tobacco Law
South Korea's Ministry of Gender Equality and Family said on September 14 that it plans to designate unmanned e-cigarette stores as businesses where minors are prohibited from entering or working. Operators would be required to verify customers' ages and display notices restricting access by minors. The proposal is open for public comment through October 6. The move follows an April expansion of South Korea's statutory tobacco definition that brought products made with natural or synthetic nicotine under the Tobacco Business Act. Nicotine-free liquids and products using nicotine analogues such as 6-methylnicotine, however, remain an emerging regulatory issue.

Exclusive Analysis | Smoore H1 Revenue Rises 19.9% Amid Growth Concentration, Profit Pressure and Slowing Momentum
Smoore’s first-half 2026 revenue rose 19.9%, but the results revealed growing structural risks beneath the headline growth. Heat-not-burn contributed about 61% of incremental revenue and remains driven largely by one core customer, while traditional vaping markets diverged, own-brand growth slowed and China enterprise revenue declined further. Gross profit and adjusted profit lagged revenue growth, while second-quarter revenue growth slowed to about 1.9%, putting greater focus on the quality, concentration and sustainability of Smoore’s expansion.
