We do actually support a number of research projects to look at the harms and possible benefits of e-cigarettes. We're supporting work to study the chemical components, actually, that are released by vaping products. We're also supporting a large-scale clinical trial that started in September 2015, still ongoing, on really looking at the safety and effectiveness of the use of the e-cigarette for smoking cessation.
