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.

2Firsts Data | China’s U.S. Vape Exports Have Yet to Regain Previous Growth Momentum in H1 2026, but Hardware Grew 15.2% and 6-Methyl Nicotine-Related Products Rose 234.7%
China’s vape exports to the U.S. reached approximately $1.58 billion in the first half of 2026, remaining broadly stable from a year earlier but still below previous growth momentum. 2Firsts’ analysis of China Customs data shows that the U.S. market has not simply returned to its previous trajectory after the enforcement shock and inventory-driven swings of 2025. Instead, export momentum is shifting across product categories. Vaping devices and atomization hardware increased 15.2% year over year, while 6-methyl nicotine-related and other nicotine substitute products surged 234.7%. Meanwhile, traditional nicotine-containing vaping products continued to face pressure.
