Why are e-cigarettes more harmful than real cigarettes?

The nicotine content of some electronic cigarettes is too high, which may be much more harmful than ordinary cigarettes. Although e-cigarettes contain no tar, the nicotine in them is not harmless. Simply inhaling nicotine can also pose health risks. Nicotine itself is not a carcinogen, but it can act as a "tumor starter". In addition, there is sufficient evidence that exposure to nicotine in fetuses and adolescents will have long-term adverse consequences on brain development.

In a new study, a team led by researchers from the University of Birmingham, UK, simulated the contact between vapor generated by liquid heating of electronic cigarettes and alveolar macrophages in the laboratory. These cells come from the lungs of healthy non-smokers.

Alveolar macrophages are immune cells that can devour and remove dust, bacteria and allergens. According to the team report, e-cigarette vapor will damage the function of alveolar macrophages. Researchers believe that this shows that the harm of e-cigarettes may be greater than previously thought.

Harm of electronic cigarette

When people use e-cigarettes, they may inhale many other undiscovered toxic compounds besides nicotine. At the same time, the second-hand smoke produced by e-cigarettes may also be harmful to health. E-cigarettes also release inhalable liquid fine particles and ultrafine particles, nicotine and carcinogens into the room. Because e-cigarettes do not produce smoke, it is easier to mislead consumers and make them have the wrong idea of safety and health.
