E-cig study indicates ‘significantly reduced’ carcinogens compared to smoking

Posted by

A study conducted by lead author Dr. Maciej Goniewicz of the Roswell Park Cancer Institute suggests that even one week of vaping can be as much as 64% less toxic in carcinogens than smoking. Goniewicz and his research team began their study by focusing merely on the possible differing effects -both positive and negative – that e-cigarettes produce on the human body as compared to conventional combustibles.

What they discovered is that vaping devices are not only far less carcinogenic, but they are also significantly more effective as a smoking cessation tool over the long term. Compared to the more commonplace Nicotine Replacement Therapies (NRTs) manufactured by Big Pharma like “the patch” and nicotine gums, e-cigs can be up to 45% effective. The study is published online at the Oxford Academic Nicotine and Tobacco Research website and has drawn a great deal of attention by the global medical community.

Guidelines of the vaping study

The scientists began by soliciting a small sample group of twenty smokers. Over the course of the study, they collected periodic urinary biomarker samples while measuring for thirteen different carcinogens, one nicotine metabolites, eight volatile organic compounds (VOCs), four polycyclic aromatic hydrocarbons, and one tobacco-specific nitrosamine. Measurements were taken both before and after each of the participants successfully transitioned to vaping for a period of two-weeks.

“After switching from tobacco to e-cigarettes, nicotine exposure remains unchanged, while exposure to selected carcinogens and toxicants is substantially reduced.”

“To our knowledge, this is the first study that demonstrates that substituting tobacco cigarettes with an e-cigarette may reduce user exposure to numerous toxicants and carcinogens otherwise present in tobacco cigarettes. Data on reduced exposure to harmful constituents that are present in tobacco cigarettes and e-cigarettes can aid in evaluating e-cigarettes as a potential harm reduction device.”

Significant findings of the Goniewicz research include a 57% reduction in the tobacco-specific nitrosamine on average within the first week and a 64% decrease after Week 2. Furthermore, the hydroxyfluorene quantities plummeted by 46% and 34% during the same timeframes. And each of the carcinogenic measurements showed significant reductions of similar variations compared to smoking.

Goniewicz and his team also determined that 45% of the control group were able to successfully quit smoking via vaping well after the study’s conclusion. While the vaping study was comprised of only a small sample group of twenty participants, the scientific conclusions also support the findings of another vaping study conducted by Penn State that was recently released just last week.
