Its success continues to grow, including in Switzerland. And its effectiveness in smoking cessation, even if it is not officially recognized, is attested by many specialists.
From the classic mint fragrance to the enigmatic "Orleans" or "Moscow", more than 8000 electronic cigarette liquid flavors are now available, according to figures from the World Health Organization (WHO), and it would exist in the world more than 460 manufacturers of electronic vaping devices. This practice has become, in just over two years, a real social phenomenon. Including in Switzerland where several associations of vapers, such as Helvetic Vape or Vap-Romandie, have emerged. These structures aim, among other things, to defend vaping and to make the voice of vapers heard in the political and medical debate.
Many discussions on vaping forums are about smoking cessation. The figures show that the majority of users have come to the e-cigarette to reduce or stop their smoking. And, for a majority of vapers, this method would be more effective than the use of patches or nicotine gums. "These products have existed for thirty to forty years but have never allowed to influence the sales of cigarettes as the electronic cigarette does today", comments Jean-François Etter, head of the prevention group of the Institute of Global Health from the University of Geneva.
But the use of the e-cigarette for smoking cessation is still not officially recommended, especially for lack of clinical data attesting to its effectiveness. Some works published in 2014 have even revived fears about its safety. Last December, the publication of a report by Japan's National Institute of Public Health concluded that e-cigarette vapor contained carcinogens similar to those found in cigarette smoke, such as formalin or acrolein. But the methodology of this work has been questioned by several experts. The machine used to simulate vaping would have been set for conventional cigarettes, or it does not smoke as vaping, the frequency and volumes of puffs are different, which can skew the measurements made.
In late August, a report by the WHO sparked controversy by saying that "electronic cigarettes increase the exposure of nonsmokers and others to nicotine and several toxic substances" and that "electronic cigarettes pose a danger to adolescents and for the fetuses whose mothers use these products ". Conclusions deemed exaggerated by some experts. "We were surprised by the negative tone of the report and found that it was misleading and did not accurately reflect the available data," said Ann McNeill, a professor at the National Center for Addiction at King's College, London, in London. review Addiction.
The publication, the December 17, by the very serious Revue Cochrane (an independent non-profit organization that offers systematic reviews of the scientific literature) of an initial synthesis of the scientific literature on e-cigarettes could advance the debate. The authors conclude that the e-cigarette is an effective tool for smoking cessation. By using liquids containing nicotine, 9% of users quit smoking cigarettes in the year and 36% reduced their consumption. "The number of studies in this synthesis was still low (thirteen, ed), and the quality of data not always excellent, as pointed out by the authors, remarks Jacques Cornuz, director of the University Medical Pollinique of the Vaud University Hospital Center. . But it is very important that this reputable institution has taken up the subject and continues to watch over the next publications. "
A joint study by the Universities of Geneva and Richmond (United States), published in the December issue of 22 in the journal Drug and Alcohol Dependence, shows that nicotine-containing electronic cigarettes are less addictive than tobacco cigarettes, and equally, even less, addictive than nicotine gums. Results judged "reassuring" by Jean-François Etter, who co-authored this publication. The Geneva-based tobacco expert recalls that "one out of every two smokers who will not quit smoking will die because of tobacco" and that "if uncertainties persist on the long-term effects of the e-cigarette, for those who already smoke, it allows a significant reduction of risks ". A recent study has assessed and classified the risks of all products containing nicotine. On a scale of arbitrary units, the cigarette is at 100, the e-cigarette at 4.
Nicotine soon legalized
Faced with the exponential increase in the use of e-cigarettes in Switzerland, about forty experts coordinated by Professor Jacques Cornuz have started from September on 2013 on the development of recommendations. It is on the conclusions of this Swiss Vap Study that the Federal Council based its position last May on the modification of the law: the sale of e-cigarettes and liquids containing nicotine should be possible in Switzerland in two to four years. However, the attention of users of these liquids should be drawn to the dangerousness of the product for children.
The United States has identified 2014 in more than 3500 cases of intoxication and a first fatal case. Concentrated nicotine is a powerful neurotoxic and the equivalent of a spoonful of e-liquid can be fatal in toddlers.
Regarding passive smoking, the federal law will also be applicable to electronic cigarettes: with or without nicotine, vaping in closed spaces accessible to the public will be prohibited.
