Study: E-cigarette Aerosol Enhances Optical Imaging of Lung Tissue
Russian researchers from Saratov and Tomsk universities have found that e-cigarette aerosols can enhance lung tissue contrast, potentially improving accuracy in diagnosing lung diseases.

According to a report from ABnews, research teams from two state universities in Saratov and Tomsk, Russia have recently published a study in the journal Diagnostics. The study suggests that aerosols in e-cigarettes can enhance the optical imaging contrast in lung tissue, offering the potential to improve the accuracy of diagnosing lung diseases.


This experiment simulated the use of e-cigarettes and was conducted on rats. It found that the morphology of lung tissue formation is altered by the inhalation of e-cigarette aerosol, affecting its gas exchange capabilities.

Argentina repealed its heated tobacco ban in May 2026 and introduced registration requirements for tobacco and nicotine products, while local media reported nicotine pouch sales in Mendoza.
