Understanding how vaping and smoking affect the body differently

Differentiating the biological effects of vaping from smoking by analyzing the methylome and transcriptome

NIH-funded research University of Southern California · NIH-11086089

This study is looking at how vaping and smoking affect your DNA and gene activity in healthy adults, so we can better understand the health risks of both habits and find new ways to measure their impact.

What this research studies

This research investigates the biological effects of vaping compared to smoking by analyzing changes in DNA and gene activity in healthy adults who use e-cigarettes or cigarettes. The study will measure these changes in cells and tissues to identify how the intensity and duration of use, as well as the type of products, influence health risks. By comparing users to non-users, the research aims to uncover new biomarkers that can help assess the health implications of vaping versus smoking.

Who could benefit from this research

Good fit: Ideal candidates for this research are healthy adults aged 21 and older who either vape, smoke, or do not use either product.

Not a fit: Patients who do not use e-cigarettes or cigarettes and are under 21 years old may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide critical insights into the health risks associated with vaping and smoking, potentially leading to better public health recommendations.

How similar studies have performed: While there has been some research on the effects of smoking, this specific approach to differentiate vaping from smoking through epigenetic analysis is relatively novel.
