Whether or not nicotine is found in e-cigarettes, some fragrant e-cigarettes can damage the respiratory tract and exacerbate respiratory diseases such as asthma, an international team of researchers report in the British journal Scientific Reports.
Researchers at the University of Vermont and others asked mice to inhale various flavored e-cigarettes twice a day for a period of time, then exposed them to sensitive air and conducted a control study with mice that did not inhale e-cigarettes.
found that different aromas cause different damage to the respiratory tract, such as black licorice, which increases respiratory inflammation, cinnamon, which increases respiratory sensitivity, and banana pudding, which can lead to more severe tissue scarring. The researchers did not specifically analyze which ingredients in scent additives cause these damage. However, previous studies have confirmed that some cream and cinnamon additives in e-cigarettes are toxic, while mint-flavored additives are carcinogenic.
suggest that people with respiratory conditions such as asthma should be particularly vigilant about e-cigarettes, and that health authorities monitor e-cigarettes, taking into account health risks.
e-cigarettes look and taste similar to regular cigarettes, mainly by heating and evaporating nicotine solutions, providing smokers with a similar feeling to smoking regular cigarettes, but the safety of e-cigarette adders is also a concern.
