Is vaping actually 95% safer than smoking? The answer is yes and there's scientific evidence supported by leading health organizations to prove it.
Public Health England (the English Government Public Health Agency) and The Royal College of Physicians reached the same conclusion after conducting comprehensive, independent reviews of e-cigarettes in 2015, 2016, and 2018.
The Royal College of Physicians concluded, "... the available data suggest that they are unlikely to exceed 5% of those associated with smoking tobacco products, and may well be substantially lower than this figure."
To summarize, The Royal College of Physicians, a British professional membership body dedicated to improving the practice of medicine, states that vaping is 95% safer than smoking traditional cigarettes.
To even prove their scientific research even further, the same 95% figure had been estimated by an international expert panel assembled by the Independent Scientific Committee on Drugs in 2014. Their studies included 12 products and 14 harm criteria.
In the United States, the National Academies of Sciences, Engineering and Medicine, made a statement that e-cigarettes and vaping are "far less harmful" but did not give an exact percentage. Even though an exact figure wasn't presented, it's SAFE to assume that vaping is indeed much more safer than smoking cigarettes and provides a a glimpse of the realistic level of risk which is meaningful for smokers looking to switch.
How Was The 95% Figure Reached?
Almost all the harm from smoking a traditional cigarette comes from the inhalation of smoke and tar. Not to mention the thousands of other chemicals and toxins produced from burning tobacco. Vaping, instead, aerosolizes a liquid with far fewer ingredients without the need for combustion. In return, the risk from vaping is immensely lower than smoking. This is due to the absent of smoke and toxins; which contains lower than 1% in vapor products. The lower levels of toxins result in lower health risks.
Also, toxins and carcinogens measured in the body of vape users are far lower compared to smokers. It makes sense why there hasn't been one death so far from vaping nicotine only.
Health improvements from vaping can also be measured compared to smokers; from reduced risk of heart attack and stroke, lower blood pressure, as well as improvements in asthma and emphysema. All-in-all, people feel a lot better and their well being improves when switching over to vape.
Finally, and one of the most important points, the risk of cancer is estimated to be less than 1% of the risk from smoking combustible cigarettes.
