Preliminary findings link long-term vaping to persistent changes in lung function
Researchers found 22 young e-cigarette users had a significant drop in FEV1 after about 12 months, though the pilot study was small.
- A new study published in Tobacco Control on Tuesday links long-term vaping to persistent lung function changes in young adults. Researchers at Florida International University observed measurable decline in lung capacity among 22 participants over 12 months.
- Scientists fear this damage could increase the risk of COPD, an incurable condition affecting around 1.7 million Britons. With more than 5 million Britons using e-cigarettes, researchers warn vaping might contribute to lasting respiratory harm.
- Participants vaping 30 or more times daily experienced a 240 ml decline in FEV1, while those vaping five to nine times daily saw a 100 ml drop, demonstrating a clear dose-response relationship.
- Study author Dr Wasim Maziak emphasized findings provide 'credible evidence' of long-term effects, though the small sample size requires larger investigations. Experts like Dr Katie East noted the pilot study lacked a control group, limiting definitive conclusions.
- While vaping is generally considered less harmful than smoking, experts remain concerned about inhaling chemicals over many years. Future research must determine whether these persistent lung changes truly elevate COPD risk, as current evidence remains preliminary.
