New E-Cigarette labels aim to clear up nicotine confusion
NCT ID NCT07553585
First seen Jun 27, 2026 · Last updated Aug 18, 2026 · Updated 2 times
Summary
This study tests two new types of nicotine labels for e-cigarettes: one showing nicotine concentration and another showing nicotine emissions (flux). Researchers will survey 2500 youth and adults in the US to see if these labels help people better understand nicotine strength compared to current labels. The goal is to improve public knowledge about nicotine in vaping products.
