The potential ofelectronic nicotine delivery systems (ENDS) to reduce the cardiovascular and other disease risks ofsmoking is of great interest. While many smokers report using ENDS for cessation, their impact under real-world use patterns and conditions on adult smokers’ quitting behavior isuncertain. The objective ofthis study was togenerate more recent and comprehensive evidence on the effect of“real world” ENDS use on the population quit rates ofadult smokers while taking account of frequency and duration ofuse, device type, e-liquid flavor, and reasons for use. We found no evidence that ENDS use, within context ofthe 2015–2016 US regulatory and tobacco/vaping market landscape, helped adult smokers quit atrates higher than smokers who did not use these products. Absent any meaningful changes, ENDS use among adult smokers is unlikely tobe asufficient solution toobtaining ameaningful increase in population quit rates. Additional research is needed to reconcile the divergent literature and monitor the impact of ENDS inan environment of rapidly evolving markets and regulatory policies.
