What this trial studies

This study investigates how menthol-flavored e-cigarettes affect addiction levels and exposure to harmful substances among users aged 21-35. It aims to understand the influence of menthol on puffing patterns and nicotine dependence, particularly in the context of rising e-cigarette use among young people. Participants will be required to abstain from e-cigarette use for 12 hours before each session, during which they will use either menthol or tobacco-flavored e-cigarettes. The findings could provide insights into the health implications of menthol in e-cigarettes and inform regulatory decisions.
