Can nicotine lozenges and E-Cigs protect kids from secondhand smoke?
NCT ID NCT01935713
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving nicotine lozenges, e-cigarettes, or dissolvable tobacco lozenges to caregivers who smoke could reduce the amount of secondhand smoke their children are exposed to. The 89 participating caregivers were not interested in quitting smoking but were willing to try these products. Researchers measured changes in children's saliva cotinine levels to track exposure.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Nicotine replacement products (lozenges, e-cigarettes, dissolvable tobacco lozenges)
What this could lead to
If successful, this could offer a way for caregivers who are not ready to quit smoking to reduce their children's exposure to secondhand smoke.
What could go wrong
This is a small, early-stage study (89 participants) with no control group, so results may not be generalizable. The products themselves contain nicotine, which has its own health risks.
