Study finds reduced toxicity of ENDS compared to cigarettes.
Researchers validated reliability of results. Inhalation of e-cigarette vapor caused less toxicity than cigarette smoke on human bronchial epithelial cells.

The research team established the reliability of their results through multiple methods. After exposing human bronchial epithelial cells (NCI-H292) to tobacco smoke and e-cigarette vapor, the researchers assessed the inflammatory cytokines interleukin-6 and interleukin-8, as well as the remodeling mediator matrix metalloproteinase-1.


Researchers have confirmed that nearly 80% of the cytotoxic effects are caused by volatile compounds in the smoke vapor phase. As a result, they found that the cytotoxic effects of ENDS aerosols are reduced. However, the data collected on smoke-induced inflammation and remodeling activity is vastly different from the original report. Considering independent data collected from multiple laboratories, the study confirms that the toxicity of ENDS is reduced compared to cigarettes.

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
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.
