UK Launches £1.46M Study on Long-Term Vaping & Lung Health
The University of Birmingham is set to lead a major new research project, named EVALUATE, to investigate the long-term benefits and harms of vaping on respiratory health. The four-year cohort study, funded by a £1.46 million grant from the Medical Research Council (MRC), aims to address critical unanswered questions about the effects of prolonged e-cigarette use on the respiratory system.
Building on the university’s internationally recognized work in e-cigarette studies, the project will provide crucial data to help individuals make informed choices about vaping, both as a short-term smoking cessation strategy and for longer-term use. Dr. Aaron Scott, Associate Professor in Respiratory Science at the University of Birmingham and the study’s chief investigator, explained the project’s focus: “We will study how vaping affects important airway immune cells and the epithelial cells which line the insides of the lung. Since these cell types play a critical role in the development of smoking-related lung diseases, these changes will provide clear insight into vaping’s on lung health.”
The multi-faceted study will employ advanced techniques to gain a comprehensive understanding of vaping’s impact. Dr. Dhruv Parekh, Director of the University Hospitals Birmingham Clinical Research Facility, noted that studying immune cells from both the blood (for indirect effects) and directly from the airways via bronchoscopy (for direct effects) will provide a “complete picture.”
A key component of the research will be investigating how vaping alters the human microbiome. “Smoking can drastically alter microorganisms in our bodies, particularly in the airways,” said Dr. Mike Cox, Assistant Professor in Respiratory Microbiome. “This project will allow us to uncover how vaping impacts this balance and map out how this changes over time.”
The study will also analyze the accumulation of toxicants within the airways after vaping. Previous work from Dr. Scott’s lab has shown that toxicants formed from the breakdown of e-liquid can negatively impact immune cells, independent of nicotine’s effects. Professor Luis Mur of Aberystwyth University will lead this investigation using cutting-edge mass spectroscopy to monitor how toxicants in the airways change as people transition from smoking to vaping.
The EVALUATE study will run alongside a complementary clinical trial examining the impact of vaping on patients with chronic obstructive pulmonary disease (COPD). The research team will begin recruiting participants for the EVALUATE study in the Autumn of 2025.
