The US Food and Drug Administration is considering reductions in the nicotine content of cigarettes to reduce smoking and tobacco dependence. A randomized study showed that even non-daily, intermittent smokers (ITS) reduced their cigarette consumption when switched to very-low-nicotine-content cigarettes (VLNCCs). This paper assesses whether switching ITS to VLNCCs results in decreased dependence and whether subsequent cigarette consumption is mediated by decreased dependence. ITS randomized to VLNCCs (n = 118) or normal nicotine content cigarettes (n = 120) completed multiple measures of dependence (Fagerstrom Test of Nicotine Dependence [FTND], Nicotine Dependence Syndrome Scale [NDSS], Wisconsin Inventory of Smoking Dependence Motives [WISDM], and Hooked on Nicotine Checklist [HONC]) at Baseline and 2, 6, and 10 weeks after randomization. A principal component factor score captured common variance among these measures (except FTND). Cigarettes per day (CPD) was assessed by three convergent methods. Switching ITS to VLNCCs reduced dependence on all measures except the WISDM Secondary Dependence Motives and HONC. Except for the effects on the factor score, these effects of VLNCCs could be accounted for by contemporaneous CPD. Week-2 dependence measures did not prospectively predict weeks 3-4 CPD, once antecedent dependence and CPD were accounted for. "Cheating" among participants who appear to have smoked conventional cigarettes did not affect the findings. Among ITS, switching to VLNCCs results in reduced tobacco dependence. However, the reductions in dependence appear to be secondary to effects on cigarette consumption, and do not appear to be an independent predictor or cause of reduced cigarette consumption.
