Research at ERS Congress in Barcelona Warns of Trends in Adolescent Smoking and Vaping

The European Respiratory Society (ERS) Congress just concluded in Barcelona has attracted international attention with a series of in-depth studies on smoking and vaping trends among young people. These findings not only change the way we look at respiratory health but also pose major challenges for public health policy. In the context of the pandemic and the digital consumer trend, tracking nicotine behavior in adolescents has become more urgent than ever. Analysis from three independent studies presented at the conference shows a clear shift in nicotine exposure. The Irish longitudinal cohort study with 3,380 participants aged 13-25 found that e-cigarette use rose to 38% at age 25, surpassing 25% for conventional smoking. The large-scale UK RCPCH synthesis of 81 studies, screening over 14,000 articles, affirmed that vaping is linked to symptoms like dry cough, wheezing, bronchitis, and asthma episodes. The ERJ Open Research physiological study added by measuring physical performance, showing a 15% reduction in capacity among users compared to non-users, due to lower oxygen retention, poorer CO2 elimination, and subclinical vascular inflammation. The context of these studies raises big questions about the future of preventive medicine for the youth. With COVID-19 disrupting physical activity and healthy habits, the shift to vaping among teens created a data gap on long-term impacts. Researchers emphasize that this is not just personal health but a major public health economic burden, with rising costs for asthma, bronchitis, and vascular disease treatment in developing countries. A deeper analysis of the research methods shows high reliability. The Irish study used a population-based sample, avoiding clinic bias. The RCPCH synthesis applied a strong evidence framework, aggregating data from multiple sources. The physiological study provided clear mechanistic evidence on vascular inflammation and reduced lung capacity. However, limitations remain in causal inference, as studies are mostly observational. Poly-use – combining multiple nicotine products – may increase actual nicotine load significantly, exceeding single-product indicators. From a health economics perspective, the boom in the e-cigarette market is shifting consumer dynamics. Revenue from conventional tobacco is declining among youth, while novel nicotine products like vapes, nicotine pouches, and heated tobacco are rising. Healthcare costs for asthma and chronic respiratory diseases related to nicotine could reach billions of euros annually in Europe if trends continue. Prevention policies need to balance advertising restrictions and support for adult smokers switching. Data also shows earlier onset, with many teens starting with e-cigarettes without prior conventional smoking. This complicates tracking smoking rates – once seen as a proxy for nicotine harm. New composite nicotine exposure metrics are now needed for accurate assessment. Researchers call for long-term surveillance to monitor cardio-respiratory outcomes in poly-users. With evidence of vascular inflammation and sudden fatigue, early detection through routine screenings in schools or clinics is essential. Policies like social media ad bans and higher taxes on novel products can mitigate potential harm. Overall, ERS Congress research confirms that e-cigarettes are no longer a 'safe alternative' but the main channel for youth nicotine exposure. Converging evidence from multiple study designs builds confidence in this trend, though more data on long-term effects is needed. Health policy must base decisions on this evidence to protect the next generation, avoiding letting consumer markets drive unhealthy behaviors. In a global context, Europe leads regulatory efforts, but developing countries need to learn to avoid repeating mistakes. Integrating this research into public health strategies will reduce healthcare burdens and improve quality of life for future generations. Scientists stress that nicotine behavior in adolescence not only affects lungs but also the developing brain, impacting learning and sports. Further economic burden analysis shows that without intervention, healthcare costs for asthma and bronchitis in youth could rise 20-30% in the next decade. School-based prevention programs need to focus on awareness of e-cigarette risks, combined with psychological support for teens. International bodies like WHO are considering unified regulatory frameworks to control advertising and online marketing. Conclusions from the studies emphasize that current data is a threshold for future research, focusing on 5-10 year follow-up to assess lung and heart impacts. Researchers are committed to sharing raw data for verification. ERS Congress has laid the foundation for broader discussions on balancing health protection and consumer freedom among youth. Evidence on reduced lung capacity and vascular inflammation indicates the need for routine screenings in high-risk groups, especially those using e-cigarettes from a young age. Tax policies and social media ad bans can reduce early initiation rates. Future studies should include brain development impacts, as nicotine affects adolescent brain development. In summary, ERS Congress findings provide a comprehensive picture of nicotine trends in youth, highlighting the urgent need for immediate action by policymakers. With data from over 14,000 articles and 3,380 participants, these studies are highly referential. Countries need to integrate these recommendations into public health strategies to protect future generations.
