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

Delay discounting, or the devaluation of delayed outcomes (for overview, see Madden and Johnson, 2010), serves as a reliable behavioral marker of cigarette use and dependence (Bickel et al., 2014). In between-group comparisons, a large body of evidence demonstrates that cigarette smokers show greater discounting of delayed rewards than non-smokers (e.g., Bickel et al., 1999; MacKillop et al., 2011). Within groups, discounting correlates positively with smoking frequency and dependence (e.g., Ohmura et al., 2005; Amlung et al., 2017), negatively with intention to quit smoking (Athamneh et al., 2017), and prospectively predicts both smoking initiation and relapse (Audrain-McGovern et al., 2009; Sheffer et al., 2014; Yoon et al., 2007).
