Abstract

Studies have shown that food deprivation is associated with increases in the self-administration of nicotine and other substances in laboratory animals. However, little is known about the effects of food deprivation on substance use in humans. The purpose of the present study was to compare smoking rates, expired carbon monoxide levels, and smoking topography in 15 female participants during a state of acute food deprivation and in a non-deprived state. A within-subjects design was utilized to test the primary hypotheses that smoking rate and expired carbon monoxide levels would be greater among the participants in the food-deprived condition than in the non-deprived condition. Analyses indicated that expired carbon monoxide levels were significantly greater in the food-deprived condition than in the non-deprived condition (p = .05), although no differences were found in the total number of cigarettes smoked during the laboratory session. Analysis of smoking topography indicated that the time to first puff was significantly greater in the non-deprived condition (p = .03), while the sum of the interpuff intervals (p = .02) and the time to removal from the last puff were greater in the food-deprived condition (p = .03). The total time total smoking was marginally greater in the food-deprived condition (p = .10). Findings suggest that females may alter the manner in which they smoke during acute food deprivation.
