Physicians and public health officials have been paying increased attention to possible health and safety issues surrounding the use of electronic cigarettes. Numerous medical organizations, official and unofficial have made statements regarding their views about the health and safety of e-cigarettes. All agree that more research is needed. Some healthcare groups have hesitated to recommend e-cigarettes for quitting smoking, because of limited evidence of effectiveness and safety. ==International== In July 2014, a report produced by the World Health Organization (WHO) for the Conference of the Parties to the WHO Framework Convention on Tobacco Control, found there was not enough evidence to determine if electronic cigarettes can help people quit smoking and made various recommendations as to a suitable regulatory framework for them.〔 It suggested that smokers should be encouraged to use approved methods for help with quitting instead.〔 But the same report also mentioned expert opinions in scientific papers that suggested e-cigarettes may have a role helping people quit who have failed using other methods.〔 The report stated that "Smokers will obtain the maximum health benefit if they completely quit both tobacco and nicotine use." In August 2014, the Forum of International Respiratory Societies, which represents multiple pulmonary associated medical associations in the United States, Latin America, Africa, Europe, and Asia, released a statement in which they argued that electronic cigarettes have not been demonstrated to be safe and their benefits as a smoking cessation tool or in harm reduction has not been adequately studied. They recommended banning their use, or regulation as medicines or tobacco products if not banned, until adequate studies are performed. In January 2014, the International Union Against Tuberculosis and Lung Disease released a statement asserting that the benefits and safety of electronic cigarettes have not been scientifically proven. The statement highlighted concerns with regards to "re-normalization" of smoking behavior and exposure of third parties to possibly dangerous emissions from e-cigarettes, and strongly supported regulation of electronic cigarettes, preferably as medicines. The World Lung Foundation applauded the 2014 WHO report's recommendation for tighter regulation of e-cigarettes due to concerns about the safety of e-cigarettes and the possible increased nicotine or tobacco addiction among youth.〔(【引用サイトリンク】url=http://www.worldlungfoundation.org/ht/d/ReleaseDetails/i/32757 )〕 In October 2012, the World Medical Association released a statement which stated, "Due to the lack of rigorous chemical and animal studies, as well as clinical trials on commercially available e-cigarettes, neither their value as therapeutic aids for smoking cessation nor their safety as cigarette replacements is established. Lack of product testing does not permit the conclusion that e-cigarettes do not produce any harmful products even if they produce fewer dangerous substances than conventional cigarettes."〔(【引用サイトリンク】url=http://www.wma.net/en/30publications/10policies/e19/ )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Positions of medical organizations on electronic cigarettes」の詳細全文を読む スポンサード リンク
