First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether switching from regular cigarettes to either low or high wattage e-cigarettes changes smoking behavior and reduces exposure to harmful chemicals. 372 daily smokers who were not planning to quit were given e-cigarettes to use freely for 12 weeks, then checked at 6 and 12 months. The goal was to see if they would stop smoking regular cigarettes and how their bodies responded to the switch.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
e-cigarette devices (low wattage and high wattage)
What this could lead to
If switching to e-cigarettes helps smokers quit or reduce toxic exposure, this could point toward a less harmful alternative for people who cannot stop smoking.
What could go wrong
This is a completed study, but e-cigarettes still deliver nicotine and may have their own health risks. The results may not apply to all smokers, and long-term effects are unknown.
