E-cigarette can directly kill lung cells: Study

India TV News  

New York: A team of US researchers has found that e-cigarettes are toxic and can directly attack lung cells, weakening the immune system and boosting bacterial virulence. "The study shows that e-cigarette vapour is not benign -- at high doses it can directly kill lung cells which is frightening," said senior author Laura E. Crotty Alexander, staff physician at the Veterans Affairs San Diego Healthcare System and assistant clinical professor at University of California's San Diego School of Medicine. This work confirms that inhalation of e-cigarette vapour daily leads to changes in the inflammatory milieu inside the airways," Alexander added in a paper published in the Journal of Molecular Medicine. "Some of the changes we have found in mice are also found in the airways and blood of conventional cigarette smokers, while others are found in humans with cancer or inflammatory lung diseases," Alexander noted. Staphylococcus aureus bacteria, which are responsible for nitrate reduction in the body, were better able to form biofilms, adhere to and invade airway cells and resist human anti-microbial peptides after exposure to e-cigarette vapour.

Scientists discover exactly how vaping can DESTROY the lungs

Daily Mail  

Scientists today hailed a breakthrough after discovering exactly how e-cigarettes can damage the lungs. But smoke from e-cigarettes can stop the cells from working properly, putting users at higher risk of debilitating lung diseases such as chronic obstructive pulmonary disease — also known as COPD. It comes just a day after the death of former Hollyoaks star Paul Danan, who …

Scientists decode how smoking worsens Covid-19 infection

India Today  

Scientists have decoded how smoking cigarettes facilitates more severe lung infection by the novel coronavirus, an advance that may lead to new therapeutic strategies to help reduce smokers' chances of developing severe Covid-19. Since these stem cells were taken from the lungs of healthy, non-smoking tissue donors, the researchers replicated the effects of smoking by exposing the airway cultures to …

Vaping 'could be WORSE than smoking for lung disease', study finds

Daily Mail  

Vaping may be just as likely to cause bronchitis and emphysema as smoking cigarettes, a study suggests. E-cigarette vapour containing nicotine made bacteria found in the lungs to become more harmful, similar to cigarette smoke. The three-year study compared the effect of cigarette smoke and e-cigarette vapour on levels of bugs linked to chronic obstructive pulmonary disease. Six probable vaping-related …

E-cigarettes are also harmful to non-users, with adverse health impacts on those exposed to second-hand vapours, according to a May 2019 white paper released by the ICMR. Consumers of e-cigarettes are “more likely to use regular cigarettes later”, the report said, citing previous studies. More than 460 e-cigarette brands available in India mix the flavours and effects of traditional tobacco …

E-cigarettes are far less harmful than tobacco products, a study appears to confirm. Lungs exposed to tobacco suffered changes in 123 genes - mutating cells in a way that creates fertile ground for heart disease, inflammation, and even tumor growth. Research by the British American Tobacco R&D Center found lungs exposed to e-cigarettes suffered two gene mutations - compared to …
