A Naturalistic Randomized Pilot Trial of E-Cigarettes: Uptake Exposure and Behavioral Effects

摘要

BackgroundMost studies of electronic nicotine delivery systems (ENDS) compare self-selected users vs. non-users. The few randomized studies to date generally support a positive impact on reducing smoking behavior, but these studies are focused on guided ENDS use. This study presents a randomized naturalistic trial of ENDS with prospective outcomes of uptake and behavioral changes in smoking.
