600 participants
Jan 6, 2025
OBSERVATIONAL
Conditions
Summary
Electronic nicotine delivery systems (ENDS) are used by millions of Americans, however their long-term health effects are unknown. This research proposal will quantify the effects of long-term ENDS use on validated and novel biomarkers of cardiovascular and pulmonary disease and how they are influenced by use heaviness, age, body weight, and co-use of other products. This study will produce the most informative evidence to date on how long-term ENDS use affects cardiovascular and pulmonary health.
