Study Indicates Switching To Vaping For As Little As One Week Can Decrease Carcinogenic Exposure By 57% Study Indicates Switching To Vaping For As Little As One Week Can Decrease Carcinogenic Exposure By 57%

The research conducted by Roswell Park was published earlier this year and could prove critical for understanding vaping

Vaping continues to be misrepresented by several influential institutions across America such as the FDA and CDC, but as more research proving their efficacy is published, it’s becoming harder to subvert the truth. One such study was conducted by Roswell Park Cancer Institute, one of the most prestigious cancer researchers in the country. The study was led by Dr. Maciej Goniewicz, who has spent his career attempting to understand better biomarkers and the efficacy of nicotine-containing products. Dr. Goniewicz and his team discovered several fascinating results, but the most important was a reported reduction of carcinogenic exposure of 57% after only seven days. That number dropped further down to 64% after the full two-week study had concluded, indicating a continued drop off in risk with continued use. Their complete results were published in an article entitled, Exposure to Nicotine and Selected Toxicants in Cigarette Smokers Who Switched to Electronic Cigarettes: A Longitudinal Within-Subjects Observational Study.

Study Overview

They first found twenty smokers who were looking to quit and agreed to switch entirely to vaping for at least two weeks. Each participant was to be tested at several points over the two-week span looking into specific biomarkers, including blood samples. They compared the changes with the base readings for each participant to garner most of their results. The researchers also monitored the level of carcinogens and volatile organic compounds that are often found in combustible cigarette smoke. This included over 30 known carcinogens found in cigarette smoke as well as eight volatile organic compounds such as Benzene, Acrolein, and Ethylene Oxide, among others.

After the two weeks, only nine of the participants had successfully abstained from smoking, leaving the other 11 out of the results. But among those nine participants there was a 57% reduction in levels of potentially harmful substances after only seven days; After the full two weeks, the decline stood at 64%. The most significant reductions came in metabolites of 1 and 3 butadiene, benzene, as well as acrylonitrile. In fact, the only tested substances that remained unchanged after successfully switching for two weeks was the total level of nicotine as well as a few polycyclic aromatic hydrocarbon metabolites.


These results are essential in the fight for vaping rights. The 45% success rate of switching alone should be enough for vaping enthusiasts to feel reinvigorated. Most smoking cessation aids cannot boast such substantial success, but vaping has consistently been shown to help around 50% of people quit smoking for good. These results line right up with that standard. But the most crucial part of this study is that it improves the stance saying vaping is a legitimate way to reduce your exposure to harm, especially from carcinogens.

As anti-vaping lobbyists continue to try and equate the dangers of vaping with the well-documented harm of traditional cigarettes, studies like this are the best tool we have to fight this misinformation. Just as Public Health England found that vaping is at least 95% safer than smoking, Dr. Goniewicz and his team have shown that it doesn’t take long for smokers to start improving their health. In as little as one week, the exposure to carcinogens can be reduced by over 50%! That’s why it’s so important that we help smokers understand that vaping and smoking are not the same. It’s this poor public perception that leads to a pitiful understanding of the relative harm of vaping compared with tobacco. Several studies have shown that only a tiny percentage of the general public understand how much safer vaping is than smoking. If we want to help save the lives of millions of more smokers, the first step is fighting this misinformation.

How long was it until you noticed a marked difference in your health after making the switch to vaping? Do you think that studies like this are essential in fighting the misinformation circulating about vaping? How can we better support and spread research like this? Let us know in the comments.
