Many test and studies have been carried out on Vaping products by public health bodies or tobacco companies ever since they were invented and many of these have proved that Vaping is by far the ’less harmful’ alternative to smoking a regular cigarette.
Tests measuring the build-up of deposits inside the lungs of smokers versus vapers or the ground-breaking review undertaken by Public Health England in 2015 concluding that electronic cigarettes are 95% less harmful than normal cigarettes prove that vaping can be classed as a healthier way to gain your nicotine hit.
Now a new study undertaken by British American Tobacco, who recently landed a $50 billion deal to merge with Reynolds an American tobacco company, forming the world’s largest tobacco company to date, have just published finding showing that Vaping is not as damaging to your genes compared to smoking tobacco products.
This new studies results show that your DNA is not as affected by the vapour you inhale from an electronic cigarette when compared to that of the smoke you inhale when taking a drag from a cigarette.
British American Tobacco’s team of scientists used their Vype device in the experiments they carried out and compared the changes in DNA of a vaper to that of a smoker.
When DNA is subjected to harmful products like smoke or alcohol then the DNA of an individual can change over time and potentially life damaging changes can take place causing fatal diseases such as heart disease or cancers to form.
A 3D model of the human airway was used by British American scientists in their latest test, tissues where exposed to both the cigarette smoke and the vapours of an electronic cigarette for 1 hour in each test.
One dose of vapour was tested which matched that of the nicotine levels in a cigarette, the second dose of vapour contained double the nicotine levels and reached cells in the airway.
Genes where mapped to see which genes were switched on and off at 24 and 48 hour periods.
After 24 and 48 hours of exposure to cigarette smoke the researchers found that 873 and 205 genes where affected but there were significantly fewer genes affected in the same period of time with just three and one genes seeming to be affected when exposed to electronic cigarette vapour of either strength.
Cigarette smoke caused changes to genes involved in the development of lung inflammations, cancers and fibrosis compared to the Vapours in the Vype device with its minor changes to genes involved in cell metabolism and oxidative stress processes.
Oxidative stress has been linked to the onset of Alzheimer’s and the aging process but the levels of changes recorded in this test where classed as ‘minor changes’ to genes and therefore significantly reduces the health implications that vaping would have on an individual compared to smoking.
British American Tobacco’s head of reduced risk substantiation, Dr James Murphy said, “Our results clearly show that cigarette smoke has an adverse effect on cells, triggering a robust gene expression response.
“However, even at equivalent or higher dose of nicotine, acute exposure to the test e-cigarette vapour has very limited impact on gene expression compared to cigarette smoke exposure – it’s a striking difference.”
These new study findings will be added to the growing body of evidence that is in favour of vaping with its health benefits outweighing any negatives when compared to cigarettes and the affects they have on an individual.
