While Dr. Glantz's statement that few people have switched away from cigarettes or used e-cigarettes as a bridge to eventually go off cigarettes was not science-based, but pure speculation, there are now two studies which actually examine the trajectory of electronic cigarette and conventional cigarette use among a cohort of e-cigarette users. We are able to empirically examine Glantz's dual use argument and his claim that very few smokers are using e-cigarettes as a bridge to eventually go off cigarettes.

According to the press release: "The ERS agrees with the recent report from the World Health Organization (WHO) and is opposed to the use of unregulated e-cigarettes. While the short-term negative impact on health appears not as great as tobacco cigarettes, the long-term effects of e-cigarettes are not known. As a Society grounded in scientific principles, ERS believes that the precautionary principle should be applied when scientific evidence is inconclusive and insufficient."

The press release announcing the study results is titled "E-Cigarettes Unhelpful in Smoking Cessation among Cancer Patients."

The AHA provided recommendations for policy on the manufacturing, use and distribution of e-cigarettes in their report published on August 25th, 2014. Their policy stresses how they believe we as a society should move forward in the new and ever changing market of electronic nicotine delivery systems. Stressing the absolute importance of more research was one of the objects at the top of their list.
