[email protected] Abstract: The public health impact of nicotine vaping products (NVPs) is subject to a complex set of uncertain transitions between NVP and cigarette use. Instead, we apply an indirect method to gauge the impact of NVP use on smoking prevalence and smoking-attributable deaths (SADs) using the well-established SimSmoke tobacco control policy simulation model. Upon validating the Citation: Levy, D.T.; model before NVPs were more widely used, we project a No-NVP (i.e., in the absence of NVPs) Sánchez-Romero, L.M.; Travis, N.; while controlling for the impact of cigarette-oriented policies. The net impact of NVPs on smoking Yuan, Z.; Li, Y.; Skolnick, S.; Jeon, J.; prevalence is inferred by comparing the projected No-NVP smoking trends to corresponding trends Tam, J.; Meza, R.
