A recently published research study carried out at Bristol University showed significant differences between the effects of smoking and vapour on isolated heart cells. Smoking caused the heart cells to mount an acute stress response, however no effect was seen with vaping.
Uncertainty is inherent to the introduction of any new technology. Vaping, although becoming rapidly more popular, has been no exception. With the impending implementation of the Tobacco Products Directive across the EU area [https://www.gov.uk/guidance/e-cigarettes-regulations-for-consumer-products] and the deeming regulations across the pond [http://www.fda.gov/TobaccoProducts/Labeling/ucm388395.htm], there is currently a huge amount of contention between vapers, manufactures and regulators.
Although vaping has become more and more popular over the years, one of the main issues in its wide-spread acceptance has been the uncertainty attached to vaping. Although it is generally acknowledged that vaping is much better for your health than smoking, regulators, researchers and policy makers often cite the lack of evidence behind vaping as a cause for concern.
Although it has been good to see that the professional medical bodies have generally been in support, with the Royal College of Physicians recently making a statement recognising that electronic cigarettes “… provide an effective, affordable and readily available retail alternative to conventional cigarettes.”[ https://www.rcplondon.ac.uk/news/rcp-statement-e-cigarettes]
With this in mind, it is great to see excellent research going on at academic centres, to provide some much needed answers! In the most recent published study, scientists at Bristol University looked at the effects of cigarette smoke and e-cigarette vapour on isolated heart blood vessel cells in the laboratory. They used a Marlboro Gold cigarette to produce the tobacco smoke while using an iStick battery with Aerotank Mini atomiser (1.8Ω) with Haven fluid USA mix at 18mg/mL nicotine to generate the e-cigarette smoke. After ensuring that the nicotine level was the same they exposed heart blood vessels to either the cigarette smoke or the vapour smoke and monitored the responses of the cells by looking at the various genes that were expressed.
They found that the cells exposed to smoke showed signs of being under stress with activation of stress responses, while the cells exposed to e-cigarette vapour showed no changes and remained healthy. The researchers concluded by saying “the use of e-cigarettes as a substitute for conventional cigarettes is likely to reduce immediate tobacco-related cardiovascular harms.”
Until enough time has passed for us to get more long-term data, it is great to see experiments like this looking at the immediate effects. And even better, it appears at-least based on the evidence so far, that vaping is indeed much healthier than smoking… shock horror.
