E-cigarettes obviously damage hu @man lungs
E-cigarettes obviously damage human lungs. E-cigarettes are known for their attractive flavors, such as bananas and strawberries, and are becoming more and more popular around the world. Tobacco companies promote e-cigarette packaging as “healthy” alternatives to ordinary cigarettes. But researchers found that e-cigarettes can still cause lung damage.
Recently, a research team from the University of California, San Diego School of Medicine, the Royal Adelaide Hospital, and the University of Adelaide School of Medicine in Australia published the latest research results in the American Journal of Physiology. The report revealed whether or not nicotine is contained, e-cigarettes The flavoring chemicals in the steam can cause great damage to the lungs.
Laura Crotty Alexander, associate professor at the University of California, San Diego School of Medicine: “99% of e-cigarettes are flavorings, and companies have added a variety of chemicals to them to achieve a’perfect’ fragrance. These chemicals are toxic to the lungs. Yes, after inhalation, it will cause severe damage to the lungs and affect the level of special proteins, and maintaining this level helps the body’s immune system to function normally.”
The research team conducted a study on 21 people who used e-cigarettes and found that the disease-causing inflammatory protein had changed. Compared with people who did not use e-cigarettes, the protein content of saliva and respiratory system of each e-cigarette was higher. irregular.
Then the scientists observed how the human respiratory tract cells react to the vapors of 10 kinds of e-cigarette e-liquid flavorings using in vitro experiments. Finally, they found that all e-cigarette e-liquid damages the cells, and some flavors are more toxic than others. . The researchers said that the overall research data shows that every time an e-cigarette smokes, it causes damage to the lungs, and flavor chemicals such as chocolate and bananas are the most toxic.
Dr. Miranda Ween, the first author of the paper, said: “The toxicity and bacterial clearance of alveolar macrophages is affected by almost every e-cigarette flavor. The impact of chocolate is unexpectedly high. It can kill almost all cells and almost It completely prevents macrophages from removing bacteria.”
Crotty Alexander said: “Alveolar macrophages are one of the most important immune cells in our lungs, which can maintain the body’s homeostasis. When e-cigarette vapor is toxic, these cells will trigger an inflammatory response, disrupt the body’s homeostasis, and cause diseases. And lung injury.”
Ween believes that the easiest way to redefine the taste of e-cigarettes is to stipulate that e-cigarette oil can only use a single flavoring chemical, and this chemical must be tested and a safe concentration has been determined. Unfortunately, compared with the popularity of e-cigarettes worldwide, this kind of research is very scarce.
