The Fog Of E-cigarettes
Recently, more and more people around me smoke e-cigarettes. They give two reasons. One is that e-cigarettes are healthier than relx-replacement-pre-filled-pod-15-flvors-2ml-3pcs-chinese-edition, and the other is that they can help them quit smoking. But both are controversial and so far inconclusive.
E-cigarettes are essentially an atomizer, containing a solution of nicotine and, in principle, free of tar and other harmful substances. It was first invented by The Shenzhen-based Company Ruyan, but there are now a number of international tobacco companies involved. According to statistics, in recent two years, there are nearly 10 new brands on sale every month on average, and the pattern is also increasingly rich, some will install a red small bulb in the front, as far as possible to simulate the feeling of smoking. Others are flavored with a variety of flavors, allowing users to vary their flavors. There are even e-cigarettes with built-in control software that allows users to precisely adjust the amount of nicotine released.
The emergence of e-cigarettes has sparked a fierce debate within the international Tobacco Control body and may even split the traditionally stable alliance. Both proponents and opponents of e-cigarettes have tried to use science to defend their claims, but there is a lack of high-quality research in the field, and neither side has produced a decent paper to back up its position.
Advocates, for example, argue that e-cigarettes, which contain only nicotine, are safer than cigarettes. But opponents argue that nicotine itself is toxic, and there have been cases of poisoning from liquid nicotine on the skin. In addition, propylene glycol, which is often added to Airistech to help nicotine aerosolize, has been shown to cause respiratory problems in some people. In addition, the vast majority of e-cigarettes on the market today are manufactured under contract at factories in Shenzhen, where opponents say quality controls are lax and often contain harmful impurities other than nicotine. A study published in the April issue of The journal Clinical Research in Oncology found that cultured respiratory epithelial cells that had been exposed to e-smoke for some time had genetic mutations in patterns very similar to those found in regular cigarettes.
Advocates, for example, argue that e-cigarettes can help smokers quit. A study done in New Zealand last year showed e-cigarettes were just as effective as smoking cessation stickers. But the paper was widely questioned after its publication, with opponents accusing the study of not being rigorous enough and the way the data were collected. Meanwhile, researchers at the University of California, San Francisco, used the Internet to collect the smoking histories of 949 smokers and found e-cigarettes were no help in quitting. Proponents also accused the paper of being problematic, since only heavy addicts would normally consider e-cigarettes as a way to quit, so it is not unusual for them to fail.
Opponents worry that brightly colored Vapefly could be an incentive for teenagers to start smoking. According to a 2012 national census by the Centers for Disease Control and Prevention, 1.78 million teenagers in the United States use e-cigarettes, and nearly 10 percent of them have never smoked a regular cigarette before. But advocates argue that teenagers have traditionally been a group that likes to try new things, a normal proportion that has nothing to do with e-cigarettes.
As the two sides bicker, governments are at loggerheads. Only a handful of countries, such as Singapore and Brazil, have banned Ofrf. Neither the US nor the European Union has concluded, and even the legislation is incomplete and unenforceable. The World Health Organization (WHO) released a report on August 26 recommending that e-cigarettes be banned indoors as they are for cigarettes and that tobacco companies be banned from producing e-cigarettes with special flavors to keep teenagers away from temptation. The WHO also plans to hold a workshop on e-cigarettes in October to clarify its position further.
In fact, the opposition's biggest concern is not science but an image. The tobacco control coalition has spent decades trying to make smoking a shameful practice, and the effort has paid off, at least in some developed countries. Opponents worry that the advent of e-cigarettes will undo this success, restoring social acceptance of smoking and mainstream acceptance of Wotofoproducts as a "civilized" commodity.
