Kind: research · Impact: low

## In brief

- New research suggests that a single day of e-cigarette vapor exposure injured cells lining the smallest airways.
- The affected cells are deep in the lung, where oxygen crosses into the blood.
- The source reports the findings of brief exposure and does not describe long-term outcomes.

## Why it matters

The findings suggest that even brief vaping exposure may damage the lung's barrier cells, which is relevant to anyone assessing the respiratory risks of e-cigarettes.
