1 Comment on a letter urging WHO to treat electronic cigarettes as tobacco products or medicines: The importance of dispassionate presentation and interpretation of evidence Following our letter to the Director General of the WHO of 26 May 2014 1 Professor Stanton Glantz organized a letter in response (‘the Glantz letter’) 2 . While our letter concerned the broader issue of tobacco harm reduction and principles that should govern the policy approach to low risk alternatives to smoking, the Glantz letter attempted a scientific critique of ecigarettes (EC). Before moving to specifics, we would like to stress that our points about tobacco harm reduction remain valid and relevant, and that authors of the letter to Dr Chan stand by the principles set out in the text. We hope that WHO and the parties to the FCTC will respond accordingly. As regards the specifics, it is a matter of regret that the Glantz letter repeated examples of misinterpretation of research data that had been already criticized by a number of commentators at the time of writing ,3,4 . We believe that researchers have a duty to make every effort to be objective in presentation of evidence and that studies cited should be relevant, properly interpreted and support the conclusions drawn. In the following paragraphs we explain why conclusions drawn in the Glantz letter do not follow from the studies cited. 1. Contrary to the impression given, surveys have found that use of ecigarettes by never smokers is negligible and smoking rates are declining among youth The letter reports “… rapid growth in youth ecigarette use, including disturbing rates among youth who have never smoked a cigarette”. The CDC National Tobacco Youth Survey (NYTS) was cited in support of this statement. 5,6 In fact, the CDC states “During 2011–2012, among all students in grades 6–12… current ecigarette use increased from 1.1% to 2.1% (p<0.05), and current use of both ecigarettes and conventional cigarettes increased from 0.8% to 1.6% (p<0.05)”. 6 Thus, prevalence was 0.5% among nonsmokers
