Data are Mean ± SEM change scores from pre-exposure baseline to water cue, and post active cue for desire for a cigarette (1A) and desire for an e-cigarette (1B). The active cues are for the regular cigarette cue exposed group (n = 50) and the electronic nicotine delivery systems (ENDS) vape pen cue exposed group (n = 58). Generalized Estimating Equations (GEE) result indicates main effect of time, with post-estimation test results indicated by the brackets ([active cue = post active cue] > Water Cue), ***ps < .001.
