Results released by the National Academy of Science, Engineering and Medical Sciences on Tuesday showed that switching to electronic cigarettes can reduce some of the health risks associated with smoking. But in general, the report calls for more research into the health effects of electronic hookah, especially since electronic cigarettes are favored tobacco products for secondary school students.
The researchers classify their conclusions by supporting their evidence. Among the most supported categories, the team reported conclusive evidence that a complete shift to e-cigarettes can reduce exposure of smokers to toxic and carcinogenic chemicals found in ordinary cigarettes. However, electronic cigarettes also posed new and unusual risks. According to the commentary, "Electronic cigarette devices may explode, causing burns and catastrophic injuries." "Inhalation of electronic liquids, intentionally or unintentionally, can be fatal."
In the second largest support category, the team reports that there is ample evidence that the gas emitted by e-vapor may contain metals and chemicals known to damage DNA, such as formaldehyde. The report pointed out that nicotine in electronic cigarettes may lead to short-term increase in heart rate, smoking will lead to dependence. Those who favor electronic cigarettes are also more likely to try regular smoking cigarettes at least once, and there is moderate evidence that this may increase adolescents' addiction.
When it comes to smoking habits, there are not enough randomized controlled trials to show how electronic cigarettes accumulate on nicotine gums or just cold turkeys. But there are signs that people using electronic cigarettes are more likely to quit smoking.
There is a lot more to know about e-cigarettes. For example, while the FDA generally considers the fragrance in electronic liquids to be safe and edible, it is not actually known if most of them are safe. It is not yet clear whether e-cigarettes can cause cancer and how e-shovels affect the fetus during pregnancy. To understand whether electronic cigarettes are good or bad for public health, more high-quality research is needed.
