The objectives of this application are to 1) compare short- and long-term harm reduction and abuse liability potential of a nicotine salt pod-based electronic cigarettes (EC) in adult (AA) exclusive EC, dual cig-EC, and exclusive cig users, 2) characterize factors that predict who switches fully, partially, or not at all, and 3) examine if harm reduction can be further enhanced by treating dual users with varenicline (VAR) to eliminate cigarette smoking.
