Are Electronic Cigarettes Safer or Unsafe?

Electronic cigarettes allow you to enjoy the pleasure of nicotine, while avoiding inhalation of dozens of carcinogens and other toxic substances. But other researchers believe that electronic cigarettes are harmful and should be regulated like traditional cigarettes. At present, there is a big difference between the electronic cigarettes in the scientific world, and it seems that neither side of the opposition can convince anyone.

The inventor of electronic cigarette is chinese. Ten years ago, one of the founders of the tobacco electronics company, Han Li invented the modern version of electronic cigarettes. Since then, this cigarette that does not need to be ignited with a lighter, and does not contain more than 60 carcinogens has become popular around the world.

In his interview with French media in 2013, Han Li said that although he was the inventor of electronic cigarette, he didn't make much money because of a large number of Shanzhai goods and similar products on the market.

Ten years, the emergence of electronic cigarette products on the market is amazing. According to a study by the United States in July 2014, California University in San Diego, published by Zhu Shuhong et al as of January 2014, the electronic cigarette brand on a global network of sales reached 466, there are 7764 kinds of different flavors, and the number continues to rise. In the first 17 months of January 2014, the number of brands of electronic cigarettes rose at an average rate of 10.5% per month, while the number of brands increased by 242 per month.

Science and technology policy research at the Arizona State University Daniel Charlevitz (Daniel Sarewitz) in August 2014 published a commentary on the British "nature" magazine, proposed a thought experiment related to the electronic cigarette.

Schaller Weitz assumes that if every smoker in the United States turns to use electronic cigarettes, what will happen? He pointed out that the electronic cigarette allows you to continue to enjoy the pleasure of nicotine, while avoiding the inhalation of dozens of burning tobacco and carcinogenic substances and hundreds of other toxic substances. "If all U.S. smokers are using electronic cigarettes smoke, so 480 thousand people die every year because of smoking and the situation will eventually be avoided." He wrote.

Schaller Weitz is clearly supportive of electronic cigarettes. He believes that the causal relationship between traditional cigarettes and diseases is clear, and that electronic cigarettes are the best alternatives. "Making cigarettes look cool, expensive and stupid makes it cool and smart to use electronic cigarettes. If people have to be addicted to something, let them love something that doesn't bring cancer to themselves and their families." That's his point of view.
However, Schaller Weitz's point of view does not represent the majority of researchers. In fact, scientists are in great disagreement about how to look at new things like electronic cigarettes, and the opposing parties cannot convince each other.
To create more smokers?

Although businesses often claim that electronic cigarettes contribute to smoking cessation in advertising, some scientists are quite skeptical about it. This year, some new data have led some researchers to think that electronic cigarettes should be regulated like traditional cigarettes.
Jennifer Duke of the RTI International Institute in the United States and his colleagues published a study in July 2014 on the broadcast of American electronic cigarette commercials on young people in.

According to the study of Duke and others, electronic cigarette companies put on TV ads covering 24 million of the American youth audience. Between 2011 and 2013, teenagers saw more than two times more electronic cigarette ads on television, while young people saw more than three times more electronic cigarettes.
Other recent studies have also found that the number of electronic cigarettes mentioned in social networks is also enormous. Only in 2012 5 to June, twitter (Twitter) on the more than 23000 different users has published more than seventy thousand tweets related to electronic cigarettes. Of all these tweets, nearly 90% are commercial.

Researchers do not know the proportion of teenagers who use Twitter, but 18 to 29 years of age account for 26%, two times the proportion of users aged 30 to 49.

The researchers also found that the advertising skills used by electronic cigarettes and their allure are also increasing.

These latest results have led Stanton Graetz, Glantz of the tobacco control and Education Center at the University of Calif San Francisco, to think that it is imperative to control electronic cigarettes (Stanton). He submitted to the U.S. Food and Drug Administration in August 2014 (FDA) a review, put forward "FDA should be banned from advertising and promotional claims or implied electronic cigarettes than traditional cigarettes is more safe and effective smoking cessation tools, until the manufacturer can provide FDA with sufficient evidence to prove that the statement is correct".

Graz over the past few years has been calling for a picture of smoking control in adolescents, including "Transformers: during extinction" release, he had criticized the film in the picture not only harm smoking among teenagers in the United States, and Chinese young viewers more than the u.s..

In March 2014, Graz and colleagues published a paper, they said the survey results show that electronic cigarettes do not encourage children to stay away from cigarettes, the opposite may encourage young users to become a cigarette. They found that teenagers who used electronic cigarettes had a greater likelihood of using traditional cigarettes than those who did not use electronic cigarettes.

This conclusion has aroused a heated debate among his peers, published the Graz publications issued a response group questioned. The researchers questioned that Graz provided data does not support his conclusions, Graz confused correlation and causality: Although the use of traditional cigarettes and electronic cigarettes crowd there will be overlap, but it can not determine whether the electronic cigarette is to induce people to use traditional cigarettes, or the reverse process.

Graz later in an "natural" magazine interview, that those studies have questioned the not accurate understanding of his thesis, he still insists on his conclusion is supported by the data. He thinks
