In a study on electronic cigarettes, a survey was conducted to reproduce the situation closer to actual use cases by actually using the devices people use. As a result, remarkable levels of chromium, lead, nickel, etc. are caused by heating of the metal coilaerosolIt is proved to be included in.

Researchers at Johns Hopkins University Bloomberg School Of Public Health conducted a survey with 56 samples for electronic cigarettes. In previous studies, surveys using electronic cigarette devices just bought have been done. However, this is not the same situation that actual people are in contact with on a daily basis, and aged deterioration such as wear and deterioration is ignored. So, in order to use the electronic cigarette "closer to what people are using", the research team gathers users who are using electronic cigarettes at shops, trade fairs, etc., and actually uses devices they love I investigated the actual condition.

Researchers looked at three liquid cigarettes, "Liquid itself", "Liquid inside the cartridge", and "Aerosol", which are used for electronic cigarettes. Researchers were especially interested in metal coils for heating liquids to produce metals that are toxic to the human body? It was a point.

As a result of the survey, half of the electronic cigarettes surveyed contained liquids and aerosols in the cartridge, which contained a remarkable level of chromium, nickel and lead although the toxic metals contained in Liquid itself was a trace amount. Researchers say that chromium and nickel are associated with respiratory diseases, lung cancer and others, and that lead can cause cardiac and neurological diseases. There is no safety level in lead.

"Electronic cigarette companies, FDA, and electronic cigarette lovers know that" as coils currently used in electronic cigarettes heat up, they leak harmful metals into the liquid and it enters the aerosol " It is important to keep it ", said Ana Maria Rule, one of the researchers.

Researchers also discovered that a total of 10% of the samples contain arsenic in the aerosol. Since lead and chromium were not included in the liquid itself, the hypothesis that "due to the heating coils" was made, but unlike these, arsenic is common to three liquids, liquid itself and liquid aerosol inside the cartridge The researchers said, "I did not know what kind of circumstances arsenic was in Liquid itself", he said.

Research results which investigated the effect of electronic cigarette on the human body include "Electronic cigarette is far less harmful than regular cigaretteThere is also a thing that shows the contents that it is. However, there are many criticisms in this survey result, "The concentration of electronic cigarettes for cadmium and arsenic is small, but for chromium, nickel, zinc, lead, silver, the proportion is almost the same for both," Rule explains doing.

Researchers reported that the results of this studyAmerican Food and Drug AdministrationHe is expecting to encourage regulation by the Food and Drug Administration (FDA). Electronic cigarettes are not "completely risk-free" but "Our research adds evidence to existing research results that electronic cigarettes are the source of exposure to various toxic metals", Researchers say. Of course, we need more rigorous investigation as to how much toxic metals it will be exposed to by electronic cigarettes, but at the same time, the need for regulatory standards to protect people is discussed.
