Outcome Measures
Primary Outcomes (3)
Change in self-report craving measured by the cue-exposure rating scale
at 0 minutes, +30 minutes, +60 minutes and following first cigarette
Difference in number of subjects who initiate smoking during the smoking cue Delay to Smoking Task compared to the nonsmoking cue Delay to Smoking Task
If participant initiates smoking a cigarette during the Delay to Smoking Task
following start of Delay to Smoking Task, up to 60 minutes
Number of minutes to first puff
Number of minutes to first puff of cigarette will be recorded for participants that initiate smoking
following start of Delay to Smoking Task, up to +60 minutes
Interventions
Participants will be presented with an unlit cigarette of their brand and an opportunity to initiate ad lib smoking at any time during the 60-minute task. During this period, participants will be allowed to read books or magazines, but will hear a tone alerting them to view cues (standard smoking environments) for the final minute of each 6-minute period. A monetary reinforcer will be provided for each 6-minute period that a participant resists smoking. Once participants stop the task they can choose to smoke as much or a little as they want for the next 30 minutes. Participants will be provided with a smoking tab. Each cigarette they light will cost them from their tab.
