Impact of E-cigarette Use on the Body

The Emerging Adulthood Health Project

This study examines how electronic (e)-cigarette use impacts the body, by studying both users and non-users of e-cigarettes. Early evidence indicates that e-cig users experience adverse health effects. Results of this study may help policy-makers develop standards for different types of tobacco.

PRIMARY OBJECTIVE:

Examine the short-term impacts of vaping on pulmonary and respiratory outcomes.

OUTLINE:

Current e-cigarette users will vape their own e-cigarette device ad libitum for 30 minutes; non-users will watch a neutral video for 30 minutes. Before and after the 30 minute vaping [video] session, participants will undergo the following assessments: computer-based spirometry testing, nitric oxide breath testing, airwave oscillometry, and an assessment of endothelial function. Participants will also undergo collection of blood.

Inclusion Criteria:

• 75 e-cig users and 75 never-users
• No self-reported diagnosis of lung disease (e.g., coronavirus disease-2019 [COVID-19], pneumonia, cystic fibrosis)
• No history of cardiac event or distress
• Not currently breastfeeding, pregnant, or planning to become pregnant (e-cig users only; will be confirmed via pregnancy test)
