Is second-hand smoke from e-cigarettes harmful? Many people are not only obstructed from smoking e-cigarettes in the office or at home. When they are outdoors, smoking a few e-cigarettes will also make people around them unconsciously move away from you, forming a “vacuum zone”. Everyone avoids e-cigarettes. Smoke seems to be “poisoned” immediately after smelling it. In short, it is really difficult to smoke an electronic cigarette freely!

In fact, this worry is not unreasonable. The principle of electronic cigarettes is to heat the e-liquid with nicotine solution to a certain temperature and evaporate to produce “steam” for users to inhale, although theoretically there is no combustion process, “steam” It is also different from the “smoke” produced by the burning of tobacco, but since nicotine can be absorbed by the human body as the vapor evaporates, wouldn’t it float into the air with the vapor mist, so that people who smell the smoke will also absorb nicotine? Even make people dependent on nicotine (cigarette addiction)?

In fact, in recent years, many countries and institutions have conducted relevant tests on the vapor composition of e-cigarettes, but there are only two results, or they are not ignored, because the results may not be what some people want, or they are “out of context.” ”, speculate with “possibility”, or use wrong experimental methods to get completely wrong results, which are exaggerated by the media, causing the public to misunderstand electronic cigarettes.

Recently, the number of e-cigarette users in Canada has continued to increase. The California Department of Public Health (CDPH) has conducted sampling and testing of e-cigarette smoke. This may indicate that a confined space is filled with a large amount of e-cigarette smoke and the air is sampled and tested. , The trace amount of toxic and harmful substances can be ignored.

As part of the study to determine the health effects of second-hand vapor mist exposure in the air, the California Department of Public Health (CDPH) has been sampling air in e-cigarette stores across the country to find out whether it is harmful to people and what measures to take to respond.

Public health expert Dr. Michael Siegel published relevant research results on social media. In a relatively small and non-ventilated e-cigarette store, many employees and 13 customers in the store frequently “stuffed clouds and mists.” “, a large amount of steam mist is generated to fill the space to create an “extreme environment” that is highly exposed to steam smoke.

In fact, for users of Big Smog, this extreme environment is actually “daily”. Vapers are together and often meet each other without seeing people.

After testing and analysis, even in a small and unventilated space, more than a dozen people use e-cigarettes continuously. The smoke fills the entire space. The test report results still show that no toxic, harmful and dangerous substances have been detected to reach the danger. Degree.

This research further proves that in real life, “second-hand vapor mist” does not seem to pose any major health risks at present.

Although Dr. Siegel is the promoter of many smoking bans, based on the current evidence, he has not found a reason why the government should ban the use of e-cigarettes.

“As for electronic cigarettes, I have not seen any reasonable evidence that it poses any major harm to other people’s health.”

The CDPH official website has not released any official data related to this study. The official website was last updated on April 7, 2017.

Although the detection methods and standards may vary among countries, regions and even different institutions, the results of Dr. Siegel’s research this time show that e-cigarette smoke is not at least as harmful as most people think. At least the content of formaldehyde is very low, and the e-cigarette smoke will not contain nicotine to “poison” other people.

However, this does not mean that the smoke of e-cigarettes is completely 100% safe, and whether it is a cigarette or an e-cigarette, you must observe social morality when using it, respect others, and cannot influence or hinder others because of yourself.

The “non-toxic” e-cigarette smoke cannot be used as an excuse for “abusing e-cigarettes”, because it is only the minimum safety line for using e-cigarettes.

Individuals still strongly agree to prohibit the use of e-cigarettes in public places, and hope that every e-cigarette user and vaper can exercise strict self-discipline to change the public’s view and perspective on e-cigarettes.
