E-Cigarettes Proved Significantly Less Harmful Than Cigarettes

On November 5, Toxicology in Vitro, an authoritative global toxicology journal, published a paper by the team of Yu Suhong. Yu is an associate researcher at Fuzhou University. The paper says that e-cigarettes have significantly less impact on cells than traditional cigarettes.

This study applied exosome proteomics technology for the first time to compare the effects of e-cigarettes and combustible cigarettes on human bronchial epithelial cells. Exosomes, small intracellular membrane vesicles, contain complex RNA and proteins. They can be applied as biomarkers for early diagnosis and prognosis of diseases such as cancer.

Research data showed cigarette condensates caused more exosomal protein expression differences in cells. These were significantly enriched in intracancerous pathways. While e-cigarettes caused fewer differences. Toxicology studies have found that combustible cigarette condensate significantly inhibits cell activity. In this regard, e-cigarette condensate has no similar negative effects. It means that e-cigarettes have relatively little cytotoxicity.e-cigarettes-less-harmful-than-traditional-cigarettes

In recent years, many studies have found that e-cigarettes may be a "harm reduction product".

In 2021, Penn State University School of Medicine in the US published a paper in "Cancer". It stated that electronic cigarettes could not only be used as an effective smoking cessation tool. But reduce the production of lung carcinogens in smokers. In 2022, "Nature" magazine published a review. For patients with periodontal health, e-cigarettes may be a safer alternative to nicotine. Because they reduce the risk of oral cancer.

The associate researcher Yu Suhong said that this study is the first to systematically analyze the safety of combustible cigarettes and e-cigarettes starting from exosomes, filling the gaps in related fields.

"Research results showed that compared with traditional cigarettes, e-cigarettes are relatively less harmful and may be a harm-reducing product," Yu Suhong believes. "But they are not completely harmless, and non-smokers should not use them".


Again, the e-cigarette is proved significantly less impact on cells than traditional cigarettes. E-cigarettes is safer than cigarettes. It can be a great cigarette replacement. So if you want to quit smoking or have a healthier life, you can buy an e-cigarette kit as a cigarette alternative.
