E-cigarettes, which can be irritating to the throat and are marketed with exaggerated benefits, have led many fashion-conscious people to think they're just harmless chewing gum, but that's not the case.
The release of e-cigarettes
Such as volatile carbonyl compounds, reactive oxygen species, furan compounds, heavy metals (nickel, lead chromium), many have pulmonary toxicity. It may cause respiratory diseases, such as chronic cough and phlegm, chronic bronchitis, increase the occurrence of asthma, chronic obstructive pneumonia, acute respiratory diseases, and even cause abnormal changes in lung parenchyma.
Flavor in e-cigarettes
Acetaldehyde, benzyl alcohol, terpenes, pyrazines, menthol, sweeteners, etc. are all used as food additives, and their effects on the lung after inhalation are uncertain. And there's no limit to how much these fragrances can be used. Some aldehydes can be harmful if used in excess.
High temperature degradation product
For example, formaldehyde is a class 1 carcinogen (definite carcinogen), acetaldehyde is a class 2B carcinogen (possible carcinogen), and glycidyl glycerin (carcinogen), acetone alcohol, acrolein, diacetyl and other substances will cause damage to the human body.
For secondhand smoke smokers
Although
E-Cigarette smokers release less nicotine into the air than traditional smokers, cotinine (a metabolite of nicotine) can also be detected in secondhand smoke smokers, potentially causing addiction.
