British researchers have sharply criticized a new study published in the journal JAMA Cardiology, which linked vaping to impaired vascular function. Experts argue that due to the extremely small sample size and methodological flaws, the conclusions drawn are unfounded.
According to the cross-sectional study published in JAMA Cardiology, young adults who have never smoked but use nicotine e-cigarettes exhibit poorer vascular function and cardiorespiratory fitness. The research, conducted on participants recruited from universities in Manchester, compared data from only 17 vapers, 19 smokers, and 22 non-users at a single point in time.
Researchers from leading British universities—including University College London and Queen Mary University of London—have leveled sharp criticism at the interpretation of the results. They emphasized that, due to the extremely small sample size, reliable and generalizable conclusions cannot be drawn; furthermore, given the observational nature of the study, it is not suitable for proving causality. The experts pointed out that the authors did not adequately filter for past smoking history and failed to account for fundamental differences in lifestyle and physical activity.
Experts warned that overstating such small-scale studies and misleading communication distort public perception of risk, which may discourage smokers from switching to less harmful alternatives.
In Summary
- The JAMA Cardiology study compared data from only 17 vapers, 19 smokers, and 22 control subjects.
- British health researchers argue that because of the micro-sized sample and the cross-sectional design, a causal link between vaping and cardiovascular issues cannot be established.
- The study did not rule out past smoking with absolute certainty and ignored physical and lifestyle differences among participants.
- According to experts, exaggerated claims mislead adult smokers, making the transition to harm-reduction tools more difficult.
