In 2018, the United States Food and Drug Administration (FDA) issued an advanced notice of proposed rulemaking to reduce nicotine in tobacco products to produce a minimally addictive or nonaddictive effect, but there was a research gap in the subjective responses of reduced-nicotine-content cigarettes. We compared the responses of the modified cigarette evaluation questionnaire (mCEQ) and cigarette-liking scale (CLS) between the gradually reduced nicotine content (RNC) group and the usual nicotine content (UNC) group. Linear mixed-effects models for repeated measures were used to analyze and compare the change over time for the mCEQ and CLS across the two treatment groups (RNC and UNC). We found that the change over time for the mCEQ and CLS was significant between the RNC and the UNC treatment groups at the beginning of visit 6 with 1.4 mg nicotine/cigarette. At visits 8 and 9, the RNC group reported significantly lower satisfaction scores compared to UNC. Subscale analysis showed ...
Confirmatory factor analyses and reliability of the modified cigarette evaluation questionnaire
Addictive Behaviors, 2007
We examined the validity and reliability of the modified Cigarette Evaluation Questionnaire (mCEQ) that assesses the degree to which subjects experience the reinforcing effects of smoking. Data came from three phase II clinical trials (n = 626, n = 627, n = 312) on varenicline for smoking cessation. Comparative fit indexes and non-normed fit indexes from a confirmatory factor analysis exceeded 0.90. Cronbach's alpha for internal consistency reliability exceeded 0.70 for the Smoking Satisfaction domain and the Psychological Reward domain but was less than 0.70 for the Aversion domain; test-retest reliability generally exceeded 0.70 on the three multi-item domains and two single items. The validity and, in general, the reliability of the postulated multidimensional framework of the mCEQ are confirmed and supported by the analyses of three independent studies, with multi-item domains on Smoking Satisfaction (satisfying, taste good, enjoy smoking), Psychological Reward (calm down, more awake, less irritable, help concentrate, reduce hunger), and Aversion (dizziness, nauseous), as well as the single-item assessment on Enjoyment of Respiratory Tract Sensations and on Craving Reduction.

Introduction:The Food and Drug Administration is considering a policy to drastically reduce the allowable nicotine content of cigarettes. The current study examined whether the policy implementation approach, i.e., either immediately reducing nicotine content to very low levels or gradually reducing nicotine content over an extended period, influences policy support among people who smoke cigarettes.Methods:Adults who smoked daily were randomly assigned (double-blind) to an immediate nicotine reduction condition (0.4 mg/g nicotine cigarettes), a gradual nicotine reduction condition (15.5 to 0.4 mg/g), or a control condition (15.5 mg/g) for 20 weeks. Participants were asked if they would “support or oppose a law that reduced the amount of nicotine in cigarettes, to make cigarettes less addictive.” Logistic regression analyses assessed if policy support was affected by treatment condition, demographic covariates, interest in quitting, and subjective cigarette effects.Results:At Week 20 (N=957 completers), 60.4% of participants supported the policy, 17.4% opposed, and 22.2% responded “Don’t know.” Policy support did not differ by treatment condition. Support was greater among those interested in quitting (OR=3.37, 95% CI=2.49, 4.55). Support was lower among males (OR=0.49, 95% CI=0.37, 0.67), those with greater dependence scores (OR=0.92, 95% CI=0.86, 0.99) and participants aged 18–24 (OR=0.53, 95% CI=0.28, 0.99). No other covariates were associated with policy support.Conclusions:The majority of participants supported a nicotine reduction policy. The implementation approach, immediate or gradual reduction, did not affect policy support. Participants interested in quitting smoking were more likely to support a nicotine reduction policy.

A broadly mandated reduction of the nicotine content (RNC) of cigarettes has been proposed in the United States to reduce the addictiveness of cigarettes, to prevent new smokers from becoming addicted and to facilitate quitting in established smokers. The primary aim of this study was to determine whether following 7 months of smoking very low nicotine content cigarettes (VLNC), and then returning to their own cigarettes, smokers would demonstrate persistently reduced nicotine intake compared with baseline or quit smoking. In a community-based clinic 135 smokers not interested in quitting were randomized to one of two groups. A research group smoked their usual brand of cigarettes, followed by five types of research cigarettes with progressively lower nicotine content, each for 1 month, followed by 6 months at the lowest nicotine level (0.5 mg/cigarette) (53 subjects) and then 12 months with no intervention (30 subjects completed). A control group smoked their usual brand for the sa...

This study examines whether tobacco dependence severity moderates the acute effects of reducing nicotine content in cigarettes on the addiction potential of smoking, craving/withdrawal, or smoking topography. Participants (N = 169) were daily smokers with mild, moderate, or high tobacco-dependence severity using the Heaviness of Smoking Index. Following brief abstinence, participants smoked research cigarettes varying in nicotine content (0.4, 2.4, 5.2, 15.8 mg nicotine/g tobacco) in a within-subject design. Results were analyzed using repeated measures analysis of co-variance. No main effects of dependence severity or interactions with nicotine dose were noted in relative reinforcing effects in concurrent choice testing or subjective effects on the modified Cigarette Evaluation Questionnaire. Demand for smoking in the Cigarette Purchase Task was greater among more dependent smokers, but reducing nicotine content decreased demand independent of dependence severity. Dependence severi...

To determine effects on craving, user satisfaction, and consumption patterns of two new nicotine replacement therapies (NRT) used for eight hours after overnight tobacco abstinence. Design In a within-subject, cross-over trial participants were randomly assigned Zonnic® nicotine mouth spray (1 mg/spray), Zonnic® nicotine lozenge (2.5 mg), Nicorette® gum (4 mg) and placebo lozenge on each of four study days. Setting University research unit. Participants Forty-seven dependent adult smokers. Measurements Participants rated their urges to smoke, irritability, concentration and restlessness before and during the first hour of product use on a 100-point scale. A subsample of 11 participants provided blood samples for nicotine analysis. Findings All active products reduced craving significantly more than placebo (mean reductions of 28.6, 25.8, 24.7 and 8.9 points for mouth spray, gum, lozenge and placebo). Mouth spray relieved craving faster than placebo and gum with significant reductions within five minutes of use (mean differences of -14.5 (95% CI: -23.0 to -6.0) and -10.6 (95% CI: -19.1 to -2.1) with placebo and gum respectively. Mouth spray produced a faster time to maximum plasma nicotine concentration (14.5 minutes, 95% CI: 8.0 to 21.0) compared to the lozenge (30.3 minutes, 95% CI: 21.1 to 39.5) and gum (45.8 minutes, 95% CI: 36.2 to 55.4). Maximum concentrations of blood nicotine were higher with mouth spray (10.0 ng/ml) and lozenge (10.8 ng/ ml) compared to gum (7.8 ng/ml). Both lozenge and mouth spray were well tolerated. Conclusions The mouth spray and lozenge are at least as effective as 4 mg nicotine gum in relieving craving suggesting that they are likely to be effective in aiding smoking cessation. The mouth spray may be particularly useful for acute craving relief.
Cigarette-by-cigarette satisfaction during ad libitum smoking
Journal of Abnormal Psychology, 2009
Smoking is thought to produce immediate reinforcement, and subjective satisfaction with smoking is thought to influence subsequent smoking. We used Ecological Momentary Assessment to assess cigarette-by-cigarette smoking satisfaction in 394 heavy smokers who subsequently attempted to quit. Across 14,882 cigarettes rated, satisfaction averaged 7.06 (0-10 scale), but with considerable variation across cigarettes and individuals. Women and African American smokers reported higher satisfaction. More satisfied smokers were more likely to lapse after quitting (HR=1.1, p<0.03), whereas less satisfied smokers derived greater benefit from patch treatment to help them achieve abstinence (HR=1.23, p<.001). Cigarettes smoked in positive moods more satisfying, correcting for mood at the time of rating. The best predictor of subsequent smoking satisfaction was the intensity of craving prior to smoking. Understanding subjective smoking satisfaction provides insight into sources of reinforcement for smoking.
Reduced nicotine content cigarettes: effects on toxicant exposure, dependence and cessation
Addiction, 2010
To examine the effects of reduced nicotine cigarettes on smoking behavior, toxicant exposure, dependence and abstinence. Design Randomized, parallel arm, semi-blinded study. Setting University of Minnesota Tobacco Use Research Center. Interventions Six weeks of: (i) 0.05 mg nicotine yield cigarettes; (ii) 0.3 mg nicotine yield cigarettes; or (iii) 4 mg nicotine lozenge; 6 weeks of follow-up. Measurements Compensatory smoking behavior, biomarkers of exposure, tobacco dependence, tobacco withdrawal and abstinence rate. Findings Unlike the 0.3 mg cigarettes, 0.05 mg cigarettes were not associated with compensatory smoking behaviors. Furthermore, the 0.05 mg cigarettes and nicotine lozenge were associated with reduced carcinogen exposure, nicotine dependence and product withdrawal scores. The 0.05 mg cigarette was associated with greater relief of withdrawal from usual brand cigarettes than the nicotine lozenge. The 0.05 mg cigarette led to a significantly higher rate of cessation than the 0.3 mg cigarette and a similar rate as nicotine lozenge. Conclusion The 0.05 mg nicotine yield cigarettes may be a tobacco product that can facilitate cessation; however, future research is clearly needed to support these preliminary findings.
