A qualitative review of vaping literature concludes nicotine-based e-cigarettes are likely carcinogenic, citing DNA damage and tissue inflammation observed in lab, animal, and case studies; however, the exact cancer risk cannot be quantified yet, and experts remain divided on how this risk compares to smoking.
Reaction to a Carcinogenesis paper on the carcinogenicity of e-cigarettes drew divided expert opinion. Some scientists say the review wrongly treats any detected trace as cancer-causing and note nicotine itself is not a carcinogen, stressing that vaping exposes far fewer tobacco-related carcinogens than smoking. Others criticize its lack of systematic methodology, opaque data handling, and selective citing, arguing it does not prove vaping causes cancer or quantify risk. Overall, experts agree vaping involves harm but remains a less harmful alternative to smoking for those who switch, and there is no robust evidence that vaping equals the cancer risk of combustion cigarettes.
A comprehensive review of more than 100 studies published since 2017 finds that vaping is likely to cause lung and oral cancers, supported by human biomarkers, animal studies, and lab data on vape liquids. Long-term, population-level risk cannot yet be quantified, but the evidence is strong enough to urge caution and stricter regulation, especially given higher risks for dual users and youths who start vaping.
A December 2025 study in Environmental Science & Technology finds that aerosols from e-cigarettes can become chemically reactive after lingering in indoor air, forming organic hydroperoxides and radicals; ultrafine particles concentrate redox-active metals like arsenic, tin, and lead, creating a “chemical cocktail” that may raise respiratory health risks for bystanders. The researchers urge treating vaping emissions like secondhand smoke and reducing indoor exposure, aligning with global policy debates and bans on vaping.
For the first time in Great Britain, more adults use vapes than smoke cigarettes, with 5.4 million vaping compared to 4.9 million smoking, reflecting a decline in smoking rates and rising vaping popularity, especially among younger adults. Health experts acknowledge vaping as less harmful than smoking but caution about potential risks, especially for children and non-smokers. The government is implementing new regulations to restrict sales and marketing of vaping products to protect youth, amid ongoing efforts to reduce smoking-related deaths.
A study by UC Riverside found that heating e-cigarette fluids produces toxic chemicals, methylglyoxal and acetaldehyde, which can damage human lung cells, with methylglyoxal being potentially more harmful even at lower levels, raising concerns about long-term health risks of vaping.
A large study suggests that vaping increases the risk of prediabetes, especially when combined with traditional smoking, highlighting potential long-term health risks beyond lung issues.
The FDA has authorized Juul to continue selling its e-cigarettes and refill cartridges, citing that the products are appropriate for the protection of public health, especially as an alternative for adults switching from cigarettes. This decision follows a lengthy review process and marks a significant development in vaping regulation, despite ongoing concerns about youth usage and health risks.
Juul has received FDA approval to sell its original e-cigarettes with tobacco and menthol flavors in the U.S., marking a significant milestone for the company amid ongoing debates over youth vaping and public health concerns.
A study in mice found that in utero exposure to certain vape liquids, even without nicotine, can cause changes in skull shape and reduce weight, raising concerns about the safety of nicotine-free e-cigarette products during pregnancy.
A recent study reveals that some disposable e-cigarettes emit dangerously high levels of toxic metals like lead and nickel, surpassing traditional cigarettes in toxicity and posing significant health risks, especially to youth. Despite regulatory efforts, these devices remain popular, highlighting the urgent need for stricter enforcement and further research into their health impacts.
A UC Davis study reveals that disposable e-cigarettes emit higher levels of toxic metals, such as lead, nickel, and antimony, than traditional cigarettes, raising concerns about their safety, especially among youth, due to potential long-term health risks like lung inflammation and cancer.
A UC Davis study found that disposable e-cigarettes release higher levels of toxic metals like lead, nickel, and antimony than traditional cigarettes, posing significant health risks, especially to teens, and highlighting the need for stricter regulation and further research.
Vaping, while popular and often perceived as safer than smoking, poses significant health risks including lung cancer, DNA damage, increased heart rate, leaky gut, brain fog, weakened immune system, dental issues, and skin aging, with recent cases linking vaping to serious health consequences such as lung cancer and collapsed lungs.
A 51-year-old man from New Jersey died from an aggressive lung cancer potentially linked to long-term e-cigarette use, marking the first documented case suggesting a connection between vaping and cancer, raising concerns about the long-term health effects of e-cigarettes and the need for further research and updated screening protocols.
