A better understanding of the range of symptoms would also help health officials answer another key question: why does the disease appear?After all, e-cigarettes are nothing new."They have been sold in the United States for many years.But reports of king volcano bong illnesses have surged this year, with health officials in Illinois and Wisconsin tracking 53 cases through April, with the first symptoms being cough, chest pain and breathing difficulties.23 August 1. Illinois health officials reported the first death linked to e-cigarettes.
Does the way people use e-cigarettes complicate the problem of lung damage?
Figuring out the cause of this lung damage is complicated because people who use e-cigarettes may switch products in turn.When epidemiologists set out to determine the cause of an outbreak, they often conduct so-called case-control studies, in which they compare people who have the disease (the experimental group) with those who have similar cases but do not get sick (the control group).However, trying to establish an e-cigarette case-control study requires some detailed planning.Meaney-delman said the choice of control measures was a challenge because the investigation had not yet identified suspicious factors.
Are e-cigarettes safe?
First, let's admit that lookah glass bong are far less harmful than traditional cigarettes because they don't contain tar.In addition, the effectiveness of e-cigarettes in stopping smoking among adult smokers is significant, with a rigorous study published this year in the New England journal of medicine demonstrating that e-cigarettes are more effective than traditional nicotine replacement therapies in spurring smokers to quit.
PeterHajek, a researcher at Queen Mary University in London and the lead author of the NEJM paper, noted that many of the people in the study initially quit by using e-cigarettes flavored with tobacco, only to eventually bear fruit and quit.This way of quitting allows smokers to wean themselves off the smell and nicotine.
This has led many countries that have pushed for tobacco regulation to gradually relax their bans on e-cigarette sales."The guardian reports that the Australian parliament recently debated whether to change the ban on e-cigarettes, which lobbyists say could help reduce the use of traditional cigarettes.
In the UK, both the department of health and the department of public health support the use of e-cigarettes rather than traditional cigarettes.
What is most surprising about e-cigarettes, however, is the popularity of younger users.One in four Canadian high school students have smoked e-cigarettes, according to a recent health survey conducted in the country and the population is growing, Canadian media reported.In the United States, one in five high school students has smoked an e-cigarette, and while teen use has soared, public health officials say smoking rates in the population have not increased.In fact, teen smoking rates have continued to decline over the past decade.
Meanwhile, recent research suggests that limiting the taste of e-cigarettes may have unintended consequences.A paper published in the "substanceuse&conversion" magazine reviewed data on the use of e-cigarettes and traditional flammable products by young people aged between 18 and 29. It found that 17 per cent had reduced their e-cigarette use and would maintain or increase the number of traditional cigarettes if their tastes were restricted.Seventeen percent may not seem too big, but with millions of people now using e-cigarettes, even if only a few switch to traditional cigarettes, it could mean a surge in new smokers.
However, it should be pointed out that glass bong online will release formaldehyde, acetaldehyde and other harmful substances in the heating process, and even produce new potential hazards, such as high temperature lampblack vapor will cause acute airway and alveolar injury.In addition, manufacturers will add a variety of flavorings, because of the presence of irritation, may induce and aggravate respiratory inflammation.
"E-cigarettes have both advantages and disadvantages. Direct smoking bans will not solve the tobacco control problem, because traditional tobacco kills far more people each year than e-cigarettes could possibly kill six."It should also be noted that the current debate in the American media about e-cigarettes has more to do with the confusion of development.The e-cigarettes in question do not come from ordinary shops, but from counterfeit goods on the street.
Finally, the world health organization (who) concluded its report on the global tobacco epidemic 2019 in July by saying: "e-cigarettes are less harmful than traditional cigarettes, and if regular smokers could completely replace cigarettes with well-controlled e-cigarettes, they would be less toxic, but not harmless.
