Using e-cigarettes no longer makes you vulnerable to the new coronavirus. A group of British scientists have worked to refute speculations against e-cigarettes, mainly from the United States. Now, to further clarify, a new study published in the Journal of Primary Care and Community Health, entitled "The use of e-cigarettes has nothing to do with the diagnosis of the new coronavirus." It was conducted by five researchers from the Mayo Clinic in Rochester, USA, and coordinated by Ivana T. Croghan. The purpose of this work is to test the hypothesis that the use of e-cigarettes is associated with an increased risk of Sars-cov-2 infection.
The sample used included nearly 70,000 smokers or e-cigarette patients (69,264) over 12 years of age who sought help at the Mayo Clinic between September 15, 2019 and November 30, 2020. Therefore, the observation period exceeds one year. In fact, since mid-September, doctors have begun to record patients' current or past use of e-cigarettes as a clinical routine. The average age of the sample is 51.5 years old, and more than half (62.1%) are women. 11.1% of people were smokers or e-cigarettes, and 5.1% of people tested positive for Sars-cov-2.
The results are reassuring. Compared with generality, the study pointed out that "patients who only use e-cigarettes are less likely to be diagnosed with the new coronavirus." In other words, the author once again pointed out that e-cigarettes “do not seem to increase the susceptibility to Sars-cov-2 infection”. This work also confirmed a fact that has emerged since March 2020: smokers have a reduced risk of contracting the disease, while the risk of dual users is somewhere in between. The researchers said that in addition to dispelling the remaining doubts about e-cigarettes, these data also indicate the hypothesis: "Any beneficial effects of traditional smoking on susceptibility are not mediated by nicotine." The Mayo Clinic will conduct further research to evaluate whether the use of e-cigarettes can reduce the consequences of the new coronavirus.
