In the current investigation, nicotine yield in variations of cigarettes was altered in an attempt to directly affect nicotine dependence levels among participants. The purpose of the current study was to determine the effect of cigarette yield on participant’s reported levels of dependence through a series of self-report measures and weekly monitoring of carbon monoxide levels. Primary measurements used consisted of a cigarette purchase task tracking the fluctuation in demand of cigarettes, as well as the Fagerstrom Test for Nicotine Dependence and Wisconsin Inventory of Smoking Dependence Motives surveys completed each week during the study. Results suggested that as yield was increased, an increase in dependence could also be seen. Likewise, as yield was decreased, dependence reached a plateau or otherwise decreased compared to baseline measurements. Conclusions reported that on average participants consumed between 24-27 cigarettes per day and spent between $12.00-$40.00 on cigarettes over the course of experimental conditions. These measures along with all secondary measurements suggested that yield percentage had an effect on the level of reported nicotine dependence. The findings suggest that cigarettes produced with a greater nicotine yield aid in the overwhelming addictive element present within cigarettes. Limiting factors surrounding measures used and sample size are discussed and suggestions for future research are provided.
