Discover the truth behind the controversial claims linking vaping to cancer as we scrutinize the studies, debunk misleading information, and provide context on the safety of e-cigarettes.
A Closer Look at the Studies
E-cigarettes have been at the center of heated debates regarding their safety, particularly in the context of cancer risk. Some studies appear to link vaping to cancer, but a careful examination of these studies and their methodologies reveals that these claims may not be as straightforward as they seem. This article will discuss various studies on vaping and cancer, highlighting the controversies and debunking some misleading claims.

The Retracted World Journal of Oncology Study
A particularly contentious study was published in the World Journal of Oncology by a team of 13 researchers. This study claimed that vapers were about as likely to develop cancer as those who smoke traditional cigarettes. Stanton Glantz, a well-known anti-tobacco advocate, cited the study and asserted that not only are there “some carcinogens in e-cigarette aerosol,” but “now there is also direct evidence that people who use e-cigarettes are at increased risk of some cancers.”
However, the World Journal of Oncology’s editors later retracted the study, citing concerns about the article’s methodology, source data processing, including statistical analysis, and the reliability of its conclusions. The retraction of this study underscores the importance of critically examining scientific research before accepting its claims.
The retracted study suffered from another basic flaw, shared by other studies that weren’t retracted but probably should have been: It doesn’t consider when its subjects started vaping versus when they were diagnosed. An analysis in Internal and Emergency Medicine cited 11 studies with this problem. This is also why a 2020 study claiming that vaping causes heart attacks was retracted. Although retracted, both studies are still used by regulators.
Professor Moon-Shong Tang’s Study
Another study, led by Professor Moon-Shong Tang from New York University, found that e-cigarette vapor caused DNA damage in mice and human lung cells, which can potentially lead to cancer. While this study appears alarming at first glance, critics argue that it lacks proper context. The study did not compare the effects of e-cigarette vapor to those of traditional cigarette smoke, which is a well-established cause of cancer.
Moreover, some experts contend that the methodology used in Professor Tang’s study is not ideal for assessing the actual risks of vaping in humans. Consequently, it is essential to consider this study’s limitations when evaluating its findings and their implications for human health.
University of Southern California Study
Researchers at the University of Southern California conducted another study that suggested young people who used e-cigarettes were more likely to develop lung cancer later in life. However, this study has also faced criticism for its methodology. The researchers did not account for other factors that could contribute to the development of cancer, such as genetics, environmental factors, or the use of traditional cigarettes. As a result, the study’s findings may not provide a clear picture of the actual risks associated with vaping. This study was also retracted but is still used by regulators.
Public Health England’s Report and the New England Journal of Medicine Study
While it is true that vaping is not entirely risk-free, it is crucial to consider the risks in context. Public Health England, a government agency responsible for public health, maintains that e-cigarettes are 95% less harmful than traditional cigarettes. This assertion is based on a comprehensive review of the available evidence on e-cigarette safety.
Additionally, a study published in the New England Journal of Medicine found that e-cigarettes were almost twice as effective in helping smokers quit compared to nicotine replacement therapy. These findings suggest that e-cigarettes may play a valuable role in smoking cessation efforts and have the potential to save lives by reducing the harm associated with smoking.
Royal College of Physicians Statement
The Royal College of Physicians, a respected medical organization in the United Kingdom, released a statement emphasizing that the health hazards associated with long-term inhalation of e-cigarette vapor are unlikely to exceed 5% of the harm caused by smoking tobacco. This statement highlights the need to view vaping risks in comparison to the well-documented dangers of traditional cigarette smoking.

Evaluating the Evidence: Understanding the True Risks of Vaping
In light of the examined studies and their methodologies, the claims that vaping directly causes cancer are not substantiated. While there may be potential risks associated with e-cigarette use, it is crucial to contextualize these risks by comparing them to the well-established dangers of smoking traditional cigarettes. The scientific consensus supports the idea that vaping is significantly less harmful than smoking, and e-cigarettes may even play a vital role in helping smokers quit. As such, it is important to approach these claims critically and to prioritize evidence-based information when discussing the safety of vaping.
