No it is not. There are many studies, mainly from England, that prove the opposite. Here is a current example:

Once again, England has called on people not to believe everything that is said about the harmfulness of e-cigarettes. Studies upon studies have now made England the flagship country of vaping. Again on October 10.10.2022th, 95. On this day England's government, in this case the UK Vaping Industry Association (UKVIA) released a new report from the Office for Health Improvement and Disparities confirming once again that vaping is at least XNUMX% is less harmful than Smoking . This confirms once again that vaping is definitely a better alternative than that Smoking classic tobacco cigarettes. That is why the UKVIA calls on people to change their minds and to stop misinformation about vaping, especially about the harmfulness. Furthermore, the current study is based on 7 previous studies by Public Health England and other organizations that have dealt with the topic. Thus, there is a lot of reliable data in this study. Nevertheless, the organizers and professors of this study have not only relied on past data, but also conducted their own analysis, surveys and tests. These coincide with the previous studies and all came to the same conclusions: the e-cigarette is up to 95% less harmful than the e-cigarette Tobacco  Cigarette!

Anyone who continues to use the last excuse that such studies have been bought, please see page 13. The relationship between the authors of the study is declared there.

metals in Steam from E-Cigarettes : New overview of the scientific literature

Two researchers looked at several studies investigating the amount of metals in Steam analyzed. Their conclusions are unequivocal: these investigations exhibit inappropriate methodology that distorts their conclusions.

Many studies have been poorly conducted

For a number of years, there has been scientific consensus that vaping is less harmful than Smoking . Although the one generated by an electronic cigarette Steam Although it contains far fewer pollutants than tobacco cigarette smoke, it still consists of certain toxic molecules, in particular carbonyls, nitrosamines or metallic compounds. Since some research has already demonstrated the detection of metal compounds in E- Liquids have highlighted in traces, it is not surprising that the resulting vaporization Steam this also contains.

Some parts of an e-cigarette are even made of metal, which increases the likelihood of them being broken Steam to discover. A study to review the methodology of other scholarly work. The topic of metals in a personal vaporizer aerosol has been the subject of much scientific study since the advent of e-cigarettes on the market. However, as is often the case when a topic is the result of a great deal of research, the results vary from study to study. Last month, researchers Sébastien Soulet ( Ingésciences , France) and Roberto A. Sussman (Institute of Nuclear Sciences, Mexico) conducted a review of the scientific literature (1) on the subject. The two experts examined the results of 12 research studies conducted in laboratories and published after 2017.

Their goal was to focus on the "consistency between their experimental design, real-life use of an e-cigarette, and a reasonable exposure risk assessment." Among the studies reviewed, 9 were conducted by researchers from academic and government institutions in the United States, 1 in China, and 1 in France. Eventually only one of the vape - Industry funded.
