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

摘要

Background: Cigarette smokers show greater delay discounting (devaluation of delayed consequences) than nonsmokers, 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.
