Delay discounting and e-cigarette use: An investigation in current, former, and never cigarette smokers

•E-cigarette (EC) users showed greater delay discounting than never users.•Current smokers showed greater discounting than former and never smokers.•Effect sizes were smaller for EC compared to cigarette use.•Former smokers who transitioned to EC use showed approximately normative discounting.

Description
Summary:•E-cigarette (EC) users showed greater delay discounting than never users.•Current smokers showed greater discounting than former and never smokers.•Effect sizes were smaller for EC compared to cigarette use.•Former smokers who transitioned to EC use showed approximately normative discounting. Cigarette smokers show greater delay discounting (devaluation of delayed consequences) than non-smokers, suggesting that rapid devaluation of the future contributes to tobacco use through a mechanism in which tobacco-related health consequences are too delayed to discourage smoking. However, little work has quantified delay discounting in relation to electronic cigarette (EC) use, a tobacco product that many users believe to pose fewer negative health consequences than cigarettes. We assessed discounting of delayed monetary rewards in a web-based sample of 976 participants, stratified by both EC use (current and never) and cigarette use (current, former, and never). Controlling for demographic variance, current EC users generally showed greater discounting than never EC users (p = .019). Current cigarette smokers also showed greater discounting than former and never smokers (p
