F E AT U R E Fig 2: Illustration of puffing behaviour Characterising Vaping Products Figure 1: Framework for the scientific assessment of potential reduced risk products collective risk of the population using the products. This framework has evolved from a prototype framework developed in the course of work to develop a reduced-risk combustible cigarette. Scientists have spent several years researching the nature of tobacco smoke, identifying key toxicants and developing technologies to reduce toxicant levels in smoke. Laboratory tests showed that these technologies could successfully reduce levels of some toxicants in smoke, and clinical testing revealed that smokers’ exposure to these toxicants was also reduced. But in the case of cigarettes, the reduction in toxicants did not prove significant enough, at least in the shorter term, to be meaningful in terms of health risks5. Innovative new tobacco and nicotine products, by contrast to modified cigarettes, have significantly reduced toxicant levels. We have observed reductions of 90% and more in the levels of certain toxicants present in these new tobacco and nicotine products. These reductions are reflected when the aerosols are applied to cell-based tests in the lab
