Cancer Research Backs Ecigarettes

Not Possible to Draw Conclusions About Ecigarettes in Real Life Says Charity

The recent news that ecigarettes may cause some cancers and heart disease has been cited as important research by charity Cancer Research, but that it does not reflect the real-life effects of vaping.

A study by the University of New York made headlines this week after it concluded that nicotine inhaled through e cigarette caused cell damage and damaged the body’s ability to repair damaged DNA in mice and human cells.

But speaking to the Guardian newspaper Cancer Research said that the study was important research but that it was not possible to draw conclusions about the effects of ecigarettes in real-life.  One of the study’s authors Moon-shong Tang, professor of environmental medicine at New York University, has said the DNA changes were similar to those linked to second hand smoke.  But he added that more was needed to see whether vaping increased cancer rates.

During the study mice were exposed to ecigarette vapour for three hours a day, five days a week for three months.  The authors said this was the human equivalent of light vaping for ten years. Compared to a control group which breathed filtered air, the exposed mice were found to have damage in their lungs, hearts and bladders.  They were also found to have suppressed abilities to repair the damage.

The study also looked at human lung and bladder cells and found tissue exposed to nicotine could more easily become tumorous.

Evidence Shows Ecigarettes are Less Harmful Than Smoking

Jasmine Just at Cancer Research UK told The Guardian: “Research like this is important, but this lab study only looked at the effects of ecigarette smoke on cells and on mice, which means it’s not possible to draw any conclusions from this about how ecigarettes might affect people in real life.

“Up to two-thirds of long term smokers will die because of their addiction, but ecigarettes don’t contain tobacco. Instead they contain nicotine, which is what keeps people addicted, but is not responsible for the major health harms from smoking.  The evidence so far shows that ecigarettes are far less harmful than smoking.”

Peter Hajek, director of the Tobacco Dependence Research Unit at Queen Mary University of London said that the study shows nothing of the dangers of vaping and that it doesn’t show that vaping causes cancer.

The researchers in New York have now started longer term studies but say the results may take years to come in.
