One factor that could contribute to the differences in the evaluation of vaping safety is the regulatory frameworks in different countries. For example, in the United States, the FDA has the authority to regulate tobacco products, including e-cigarettes. The FDA has taken a cautious approach to e-cigarettes and has required manufacturers to submit their products for review to ensure that they are safe and effective for their intended use.

In the UK, the regulatory approach to e-cigarettes is different. The MHRA regulates e-cigarettes as medicinal products, which means that manufacturers must demonstrate that their products are safe, effective, and of high quality before they can be sold.

These different regulatory frameworks could lead to differences in the way that public health agencies in different countries evaluate the safety of e-cigarettes.

Scientific Evidence:

Another factor that could contribute to the differences in the evaluation of vaping safety is the scientific evidence available and the interpretation of that evidence. There is ongoing debate among public health experts about the risks and benefits of e-cigarettes, and different agencies may have access to different studies or may weigh the evidence differently when making their recommendations.

For example, a 2018 report by the US National Academies of Sciences, Engineering, and Medicine concluded that there is substantial evidence that e-cigarettes are less harmful than combustible tobacco cigarettes, but that there is also substantial evidence that e-cigarette use increases the risk of using combustible tobacco cigarettes.

In contrast, a 2021 report by Public Health England concluded that vaping is at least 95% less harmful than smoking, and that e-cigarettes are an effective tool for smoking cessation.

These differences in the interpretation of the scientific evidence could contribute to the differences in the evaluation of vaping safety between public health agencies in different countries.

Conflicts of Interest:

Finally, it is important to consider the potential for conflicts of interest when evaluating the recommendations of public health agencies. While it is difficult to say definitively whether smoking lobby groups or big insurance companies have any influence on public health agencies, it is always important to critically evaluate the sources of information being presented.

For example, in the United States, there has been concern about the potential for conflicts of interest among members of the FDA’s Tobacco Products Scientific Advisory Committee (TPSAC), which provides advice to the FDA on the regulation of tobacco products, including e-cigarettes. A 2018 report by the US Government Accountability Office found that the FDA had not consistently identified and addressed conflicts of interest among TPSAC members.

Overall, the evaluation of vaping safety is a complex issue that is influenced by a variety of factors, including regulatory frameworks, scientific evidence, and potential conflicts of interest. It is important to critically evaluate the sources of information being presented and to seek out multiple perspectives when making decisions about vaping.
