Modeling the effects of combined behavioral and pharmacological treatment on cigarette smoking: Behavioral-economic analyses

Effects of different response requirements, response-independent cigarette puffs, and an alternative nondrug reinforcer on cigarette smoking were assessed in 2 experiments. The response requirement to obtain 2 puffs on a cigarette was manipulated while various numbers of response-independent puffs were provided (0, 6, or 12 in Experiment 1; 0 or 12 in Experiment 2). In Experiment 2, effects of response-dependent money ($0.25) on smoking were assessed within subjects. Response-dependent puff consumption decreased as price increased and as the number of response-independent puffs increased. Concurrently available money also decreased response-dependent smoking. The largest decrease in smoking occurred when puffs were at the highest price and when response-independent puffs and response-dependent money were both concurrently available. Findings suggest that combined pharmacological and behavioral interventions produce the greatest reductions in smoking.
