Growing evidence is strengthening the case for nicotine e-cigarettes as an effective smoking cessation tool. A comprehensive review of global research indicates that these products consistently outperform traditional methods such as nicotine patches, gum, and behavioural support. Higher-quality studies show that quit rates among users of nicotine e-cigarettes can be around 20% to 40% higher compared to conventional nicotine replacement therapies. The findings suggest that both the delivery of nicotine and the behavioural aspects of vaping may play a role in supporting smokers attempting to quit. At the same time, important gaps remain, particularly regarding long-term safety and comparisons with certain medications. The growing body of evidence is contributing to an ongoing debate about how e-cigarettes should be integrated into public health strategies aimed at reducing smoking-related harm.

A new overview of 14 systematic reviews suggests that nicotine e-cigarettes are more effective for smoking cessation than traditional methods. The study highlights gaps in comparing e-cigarettes to newer aids and the need for global research on long-term safety. While e-cigarettes are effective for quitting, evidence on adverse events is inconclusive. The overview emphasizes the importance of high-quality data and urgent studies in low-income countries. Funding was provided by Cancer Research UK. The lead author stresses the consistent effectiveness of e-cigarettes in helping people quit smoking, despite mixed claims based on lower-quality reviews. The research aims to clarify the role of e-cigarettes in smoking cessation.

In this episode of the Science Series, Roberto Sussman breaks down why many lab studies on e‑cigarette emissions can’t be trusted—and how bad testing setups can create misleading “high toxin” results. He explains the “optimal regime” for vaping devices (power, resistance, airflow), why reproducibility requires full reporting of test conditions, and how unrealistic puffing machines can cause overheating and artificially inflate byproducts.

Nicotine e-cigarettes are found to help adults quit smoking more effectively than other methods, with quit rates up to 40% higher. A review of 14 systematic reviews across nearly a decade of studies showed consistent evidence towards this conclusion. While acknowledging the health risks of vaping, researchers emphasize its lesser harm compared to smoking and highlight concerns about youth uptake. The effectiveness of e-cigarettes may be related to factors beyond nicotine delivery, and further studies are needed to compare them to prescription drugs. The study aims to clarify misconceptions about vaping and stresses the importance of evidence amid public perception challenges.

Growing scientific consensus is emerging around the role of nicotine e-cigarettes in helping people quit smoking. A large-scale review of existing evidence shows consistent findings across multiple studies, indicating that these products can significantly improve quit rates compared to traditional methods. Nicotine e-cigarettes have been associated with cessation success rates approximately 20% to 40% higher than those achieved with conventional nicotine replacement therapies such as patches or gum. Their effectiveness may be linked not only to nicotine delivery but also to behavioural and sensory aspects that mimic smoking, making the transition easier for many users. At the same time, uncertainties remain, particularly regarding long-term health effects and comparisons with certain prescription medications used for smoking cessation. The findings contribute to an ongoing debate about how e-cigarettes should be positioned within public health strategies aimed at reducing smoking-related harm.

A comprehensive review of global evidence is reinforcing the role of nicotine e-cigarettes as an effective tool for smoking cessation. Drawing on multiple systematic reviews, findings consistently show higher quit rates among users of nicotine e-cigarettes compared to traditional therapies such as patches or gum. At the same time, gaps in the research remain, particularly in comparisons with other pharmacological treatments and in understanding long-term safety outcomes. While evidence on serious adverse effects is still inconclusive, the overall results challenge the perception that findings on e-cigarettes are mixed or uncertain. The discussion highlights the need for further high-quality studies, especially in low- and middle-income countries, to better inform future public health strategies.

Heated tobacco products are increasingly being discussed as part of the broader tobacco harm reduction debate, particularly for smokers who struggle to quit using traditional methods. These products heat tobacco instead of burning it, potentially reducing exposure to harmful chemicals compared to conventional cigarettes. Evidence suggests they are likely less harmful than smoking, though still not risk-free and generally considered more harmful than vaping. The key question is not only their relative risk, but also how effective they are at helping people move away from combustible tobacco at a population level. Supporters argue that, for some smokers, they may serve as a useful alternative when other cessation tools do not work, and therefore deserve a place in harm reduction strategies.

Why have some studies reported enormous amounts of formaldehyde and metals in vaping emissions? In this episode of Science Series with Roberto Sussman, we break down how those scary numbers can come from bad experimental conditions—especially overheating setups that don’t reflect how people actually vape. Roberto explains why “micrograms per puff” can be misleading, how to translate emissions into realistic daily exposure (based on typical puff counts), and how those totals should be compared against toxicological standards published by regulators. You’ll also hear why properly designed tests tend to find toxic byproducts far below cigarette smoke—and often below common benchmarks, with a reality-check comparison to everyday aerosols and even air pollution exposure.

The debate on e-cigarette use and oral health continues, with a recent CoEHAR review focusing on vaping's impact on oral microbiota. While e-cigarette users show varying oral microbiota compared to non-smokers and smokers, the changes lack consistency, making it hard to pinpoint a definitive vaping-related bacterial profile. Changes in the oral microbiome don't necessarily indicate disease, and definitive conclusions on vaping's oral health effects are limited by small, cross-sectional studies. More extensive, longitudinal research is needed to understand the long-term risks associated with vaping on oral health. Prof. Polosa emphasizes the preliminary nature of claims linking vaping to oral harm, indicating a need for stronger evidence.
