The authors analyzed smokers' facial expressions using the Facial Action Coding System (P. Ekman & W. V. Friesen, 1978) under varying smoking opportunity conditions. In Experiment 1, smokers first were told that they either could (told-yes) or could not (told-no) smoke during the study. Toldyes smokers reported higher urges than did told-no smokers. Unexpectedly, told-yes smokers became increasingly likely to manifest expressions related to negative affect and less likely to evince expressions related to positive affect, compared with told-no smokers. In Experiment 2, smokers were more likely to show positive affect-related expressions if the delay was 15 s than if it was 60 s. Craving may be related to both a desire to use and an impatient desire to use immediately.Recent years have seen a resurgence of interest in the topic of drug craving (e.g., Lowman, Hunt, Litten, & Drummond, 2000). Laboratory studies have proliferated in which craving is provoked using a variety of manipulations, including drug deprivation, drug use imagery, and drug cue exposure (Niaura et al., 1988). Carter and Tiffany's (1999) review confirmed that exposure to drug-related cues significantly increased self-reported urges, or cravings. Research also suggests that cue reactivity can be moderated by both person-level (e.g., heavy vs. occasional users) and situational factors.One situational factor that appears to affect self-reported urge is drug use opportunity. We recently observed across a number of studies that addicted individuals who were informed that they had an opportunity to consume their drug reported higher urges than did those who did not anticipate use, in some cases double the levels (Wertz & Sayette, 2001b). Left unresolved was whether drug use opportunity affected self-reported urge ratings in the absence of in vivo exposure to drug cues. Some have argued that there is an important distinction between cuespecific urges and general urges brought about by abstinence in the absence of in vivo drug Correspondence concerning this article should be addressed to Michael A.

These investigators recently found that smoking opportunity affected cue-specific urge ratings (Carter & Tiffany, 2001). One aim of the present study was to contrast the effects of instructed opportunity to smoke on self-reported urge prior to in vivo smoking cue exposure.
NIH Public AccessCarter and Tiffany (1999) also concluded that drug cue exposure affected nonverbal responding. Specifically, cue exposure increased heart rate, sweat gland activity, and skin temperature. Until recently, however, characterizing the emotional valence of cue reactivity has proven challenging (Sayette et al., 2000;Zinser, Fiore, Davidson, & Baker, 1999). Ideally, these nonverbal measures should be conceptually linked to a particular theory of craving rather than simply measures of convenience (see Kassel &...
