Vaping Linked to Higher COPD Risk

A comprehensive analysis suggests that both current and former users of e-cigarettes may face a significantly increased risk of developing chronic obstructive pulmonary disease (COPD). This raises concerns regarding the long-term respiratory health effects of vaping.
Key Development
The research, featured in npj Primary Care Respiratory Medicine, analyzed numerous studies, with Dr. Michael Shabil and colleagues finding a notable correlation between e-cigarette usage and COPD. Though most studies were conducted in the United States, cohorts from China and South Korea were included.
“Electronic Nicotine Delivery Systems (ENDS) promise a safer inhale but generate an aerosol rich in ultrafine particles, aldehydes, and metals.”

A recent report from the American Lung Association states that 3.4% of U.S. adults have COPD (American Lung Association).
Background
COPD, a progressive illness that obstructs airflow, has historically been associated with traditional smoking. E-cigarettes, marketed as safer alternatives, deliver an aerosol containing ultrafine particles and metals. The central question remains whether vaping helps smokers quit or creates a new generation with COPD.
Study results came from over 4.3 million adults. Of the studies, 12 used cross-sectional data, while five were longitudinal. Researchers found that current e-cigarette users had 48% higher odds of COPD compared to those who never vaped. Former e-cigarette users faced even greater risk, with 84% higher odds. Even individuals who had ever experimented with e-cigarettes had 79% higher odds.
Subgroup analysis suggested design-related nuance: cross-sectional investigations indicated a stronger link for current e-cigarette use (OR = 1.592) than cohort investigations, whose summary estimate dropped to 1.145.
However, when limiting the analysis to the two spirometry-verified cohorts, the link diminished and became non-significant (OR = 1.14).

The study suggests that e-cigarette use is associated with increased odds of COPD. Dr. Shabil and the research team urge clinicians to discuss vaping with their patients, especially younger adults. They also highlight the need for policymakers to consider the potential respiratory risks alongside any benefits e-cigarettes may have as smoking-cessation aids. Further research should focus on long-term impacts, objective COPD diagnoses, and detailed vaping habits.
