Aims An earlier study (Dols et al. 2000) suggested that cue-induced urge to smoke depends on the expectation of smoking. The present study tried to replicate the findings under stringently controlled conditions. Design A 2 (context) x 2 (cues) x 6 (trial) within-subject design. Each smoker entered two different contexts: one context predicted the future occurrence of smoking (i.e. one puff of a cigarette) and one context predicted the non-occurrence of smoking. In each context smokers were exposed to smoking cues (i.e. cigarettes and lighter) or not. Setting Laboratory at Maastricht University. Participants Thirty-two daily smokers, smoking at least five cigarettes a day for at least 2 years. Measurements. Participants reported their urge to smoke in each context in the presence and absence of smoking cues using a computerized visual analogue scale (VAS). Findings The results revealed that the urge to smoke was higher in a context in which smoking was expected relative to a context in which it was not expected. As in the previous study the urge-inducing effect of smoking cues was larger in the smoking context than in the non-smoking context. Moreover, smoking cues did not have a significant effect in the non-smoking context. Conclusions It was shown that smoking cues elicit craving due mainly to a generated expectation of the occurrence of smoking and less due to salience or long history of associative learning. Theoretical and practical implications of the results are discussed.
