How E-cigarettes work
A typical e-cigarette smoking device is made of glass or metal, with an electric heating generator inside. By electrothermal controlling the heating temperature, the active ingredient can evaporate at least combustion without inhalation of heavy smoke. "E-cigarettes" absorb steam generated by heating a liquid liquid dedicated to the By Vaping. Because it does not smoke, tar, does not accumulate in the body, and some fluids do not even contain nicotine.
Basic principles of traditional smoking
Traditional cigarettes made from tobacco leaves are available for commercial purchase. Heating with a lighter produces smoke. Heat-generated smoke contains nicotine, inhaled into the blood through the lungs. The result is increased heart rate, vasoconstriction, dopamine release, and awakening of the brain.However, by administering nicotine repeatedly in the body, nicotine action can cause intoxication. The smoke produced by burning tobacco leaves also contains tar.
It is well known that tar is carcinogenic and has health hazards such as darkening teeth and reducing taste bud function. That's where e-cigarettes came from. If only the main components are heated to atomize without causing the combustion reaction of compounds, the effect of smoking can be achieved quickly without the harm of smoke inhalation.
According to the academic research
The University of London studied lower risk of e-cigarettes than smoking
On February 28, University College London researchers published the results of a survey of 28,393 smokers in the UK between 2014 and 2023.Using monthly interviews with about 1,700 adults in England, the team found that overall awareness of the dangers of e-cigarettes has increased since 2021. In 2014-2023, the proportion of smokers who rated e-cigarettes as more harmful increased from 11% to 23%; in June 2023,57% of respondents rated e-cigarettes as equal or more harmful as smoking, and only 27% rated e-cigarettes as less harmful. Although this perception recovered at the end of 2020, the perception of adolescent e-cigarettes worsened again from 2021 to 2023 as a growing number of young people began using disposable e-cigarettes.
Dr Sarah Jackson, from the Institute of Epidemiology and Health Care at University College London, said the risk of e-cigarettes is much lower than smoking, but this has not been clearly communicated to people. This misconception is a health risk in itself, as it may prevent smokers from switching to them to substantially reduce harm and encourage some young people who use e-cigarettes to start smoking. According to Professor Jamie Brown at University College London, e-cigarettes have attracted widespread media attention as a novel product, with news articles often exaggerating their health risks compared with smoking, while 75,000 smoking deaths in England each year are relatively rare.
According to the NHS online guidelines, cigarettes release thousands of different chemicals when burning, including up to 70 toxic substances that can cause serious diseases such as cancer, lung disease, heart disease and stroke.
