Recently, the University of Catania in Italy, the University of South Florida in the United States, the University of California at Los Angeles and the University of Nebraska and other universities have published two articles on e-cigarette research in SCI journals. The two articles agreed that compared with traditional cigarettes, electronic cigarettes have lower harmful substances and lower cancer risk.



In the past ten years, the number of people using electronic cigarettes in the United States has increased sharply. In order to further study the impact of electronic cigarettes on health, the University of Catania, the University of South Florida and the University of California, Los Angeles jointly published an article titled on the world-renowned academic journal ScienceDirect. Paper for "A Close Look at Vaping in Adolescents and Young Adults in the USA".

The article points out that e-cigarette aerosol emissions are produced at lower temperatures, and compared with traditional tobacco smoke, harmful or potentially harmful chemicals are greatly reduced, effectively reducing bronchial epithelial cell toxicity and inflammatory responses. This result is also confirmed by the authoritative QRA (Quantitative Risk Assessment) method.



At the same time, the article stated that although some of the public’s concerns about e-cigarettes are reasonable, the public still has a lot of prejudices about the use of e-cigarettes by young people and the use of e-cigarettes by some users to cause asthma. Now people’s perception of the risks of electronic cigarettes is often greatly exaggerated. In fact, these problems can be solved in the future through technological innovation, quality and safety related electronic cigarette product supervision, such as improving chip design, introducing automatic cooling function to avoid harmful substances Pile up, or strengthen the supervision of listed e-cigarette products to avoid some unforeseen potential health problems, thereby reducing public concerns.



Another article "Exposure to Toxicants Associated With Use and Transitions Between Cigarettes, e-Cigarettes, and No Tobacco ", conducted a study on the issue of "comparison of the hazards of e-cigarette users, dual e-cigarette users, and cigarette users", and also came to the conclusion that using e-cigarettes alone is less harmful to the body.



The experiment divided 3,211 participants from the United States into 3 mutually exclusive groups, including 2,356 cigarette users alone, 210 e-cigarette users alone, and 645 both cigarettes and e-cigarette users. By testing the urine samples of the subjects, it was found that when the subjects transitioned from using cigarettes alone to e-cigarettes alone, the concentrations of TSNA, PAHs and VOCs (all toxic components) in the urine were significantly reduced; Similar components of BOEs (biomarkers of exposure to nicotine and other toxicants) were also greatly reduced when e-cigarettes were used alone, and vice versa.



From this, the researchers judged that the potential harm to the body from "using cigarettes alone or using cigarettes and e-cigarettes at the same time" to "using e-cigarettes alone" is lower, and suggested that people only use e-cigarettes as much as possible, so as to ensure their public health. Benefits in terms of hygiene and health risk reduction.
