Understanding the Impact of Cartridge-Based Electronic Cigarettes and Generated Aerosols on Cardiopulmonary Health
January 8, 2024 updated by: Virginia Commonwealth University
Over the last decade, e-cigarettes have become increasingly popular, due to their promotion as a healthy alternative to traditional tobacco cigarettes.
However, there are large discrepancies of knowledge in understanding how these e-cigarettes affect the user's health.
The overall goal of this study is to evaluate the impact of e-cigarettes usage on user's cardiopulmonary health
