Vaping lowers cancer-causing toxins, says University College London in UK

Posted by

On February 6, 2017, the UK’s University College London published a new e-cig study that seemingly indicates that smokers who switch to e-cigs and vaping will substantially reduce their levels of carcinogens and other toxins by as much as 97%. However, there is one small glitch. Dual use of e-cigs and combustible cigarettes is not allowed.

The lead scientist of the cross-sectional study is a man named Lion Shahan of the University College London and King's College. The study was funded by an organization called Cancer Research UK. And some 181 participants took part in the study, comprised of five distinctly different groups of people.

  • 1.Never-vapers who are also current smokers
  • 2.Long-term dual users of both e-cigs and conventional cigarettes
  • 3.Long-term dual users of conventional cigarettes and other smoking cessation tools, like the patch or nicotine lozenges
  • 4.Former smokers with over 6-months of use in only e-cigs
  • 5.Former smokers with over 6-months of use in alternative nicotine replacement therapies (NRT) only

Over the course of the study which lasted several months, scientists from the University College London conducted numerous interviews with each participant and collected regular biomarker samples of blood and urine. The team of scientific researchers were measuring the biomarkers for varying levels of volatile organic compounds (VOCs), tobacco-specific N-nitrosamines (TSNAs), and of course, nicotine.

University College London makes startling discovery

What the scientists discovered is that vape-only and NRT-only participants had the same levels of nicotine in their biomarker samples as the other three groups, but their toxicity levels were dramatically lower.

“This finding is consistent with the assertion that completely switching to e-cigarettes significantly reduces the risk of future cancers compared with continued smoking. E-cigarettes are a safer alternative to smoking tobacco in the context of developing smoking-related cancer."

Of course, many in the vaping community are disputing the claim that dual use of both e-cigs and combustible cigarettes shows no signs of lowering toxicity levels. One such pro-vaping advocate is Gregory Conley of the American Vaping Association.

“A smoker who drops from 20 cigarettes per day down to 15 may not see meaningful declines in carcinogen exposure. However, if that same smoker cuts back to three cigarettes per day with the help of vaping or a nicotine-replacement therapy, significant changes in toxin exposure will be clearly evident."

However, Conley doesn’t believe that the UK study is all that bad either. In fact, Conley says that the study should serve as a “wake-up call” to the FDA, the CDC, and other highly hostile anti-vaping organizations that have spent the past decade completely demonizing e-cigs and vaping.
