Electronic nicotine delivery system (ENDS) use during smoking cessation: a qualitative study of 40 Oklahoma quitline callers

摘要

ObjectivesApproximately 10% (40 000) of US quitline enrollees who smoke cigarettes report current use of electronic nicotine delivery systems (ENDS); however, little is known about callers' ENDS use. Our aim was to describe why and how quitline callers use ENDS, their beliefs about ENDS and the impact of ENDS use on callers' quit processes and use of FDA-approved cessation medications.
