Abstract
Research on affect-related constructs as determinants of health behavior is increasing. The Affect and Health Behavior Framework (AHBF) provides a schematic structure to label, organize, and integrate affect-related constructs. To further facilitate research and theory development in health behavior science, the purpose of the present paper is to provide a critical review and guidelines for assessment of the affect-related constructs in the AHBF. The paper is organized based on the categories of constructs in the AHBF: Affective response to health behavior, incidental affect, affect processing, and affectively charged motivation. Future research should work toward parsing constructs where possible as well as identifying overlap. Researchers are advised to consider conceptual underpinnings and methodological nuances when assessing affect-related constructs in order to build a cumulative science of affective determinants of health behavior.

Comparing the Effects of the EU- Versus the US-JUUL Pod in a Sample of UK Smokers: Nicotine Absorption, Satisfaction, and Other Nicotine-Related Subjective Effects. Nicotine Tob Res 2023; 25:1109-1115. [PMID: 36534967 PMCID: PMC10202644 DOI: 10.1093/ntr/ntac289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 10/03/2022] [Accepted: 12/16/2022] [Indexed: 12/21/2023]
Abstract
INTRODUCTION Pod Vaping Devices (PVD) such as JUUL have become extremely popular in the United States although their uptake and use in the United Kingdom remain lower. A key difference between the United States and the United Kingdom is the nicotine strength legally permitted, typically 59 mg/mL in the United States but capped at 20 mg/mL in the United Kingdom and European Union. This may limit the ability of EU vaping devices to deliver satisfactory nicotine levels. The primary aim was to compare the EU- (18 mg/mL nicotine strength) with the U.S.-JUUL (59 mg/mL) on daily smokers' subjective experiences, craving relief, and blood nicotine levels. AIMS AND METHODS Double-blind, counterbalanced within-participants design with two conditions: 18 mg/mL versus 59 mg/mL. On two separate occasions, UK smokers (N =19, 10 males, 9 females) vaped ad libitum for 60 mins and provided blood samples at baseline 5, 15, 30, and 60 min. Subjective effects (incl. satisfaction) were measured at 10 and 60 min and, craving and withdrawal symptoms (WS) at baseline, 10 and 60 min. RESULTS Satisfaction did not differ between conditions. There was a significant interaction between Time and Nicotine concentration for Nicotine Hit (p = .045). Mean self-report of Nicotine Hit increased under the use of the 59 mg/mL from 10 to 60 min and decreased under the 18 mg/mL. Participants reported higher Throat Hits following use of the 59 mg/mL (p = .017). There were no differences in other subjective effects including craving, WS relief (ps > .05). Liquid consumption was doubled under the 18 versus the 59 mg/mL (p = .001) and nicotine boost was significantly higher in the 59 mg/mL at all time-points (p ≤ .001). CONCLUSIONS The results did not support our hypotheses that satisfaction, craving, and withdrawal reduction would be higher with the 59 mg/mL JUUL. This could be because of the doubling of liquid consumption in the 18 mg/mL. Whether satisfaction and craving relief persist over the longer-term outside of the lab remains to be determined. IMPLICATIONS In a 60-min ad-lib vaping session, the EU-JUUL was found to produce comparable satisfaction, craving- and withdrawal relief as the U.S.-JUUL in this sample of UK smokers. These findings could suggest that the higher nicotine concentrations available in PVDs in the United States are not necessary for providing satisfaction and improving craving and WS. However, this was at the expense of a considerable increase in liquid consumption indicative of compensatory puffing.

Day-to-day hedonic and calming effects of opioids, opioid craving, and opioid misuse among patients with chronic pain prescribed long-term opioid therapy. Pain 2021; 162:2214-2224. [PMID: 33729213 DOI: 10.1097/j.pain.0000000000002220] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Accepted: 12/16/2020] [Indexed: 12/28/2022]
Abstract
ABSTRACT Concerns have been raised regarding the misuse of opioids among patients with chronic pain. Although a number of factors may contribute to opioid misuse, research has yet to examine if the hedonic and calming effects that can potentially accompany the use of opioids contribute to opioid misuse. The first objective of this study was to examine the degree to which the hedonic and calming effects of opioids contribute to opioid misuse in patients with chronic pain. We also examined whether the hedonic and calming effects of opioids contribute to patients' daily levels of opioid craving, and whether these associations were moderated by patients' daily levels of pain intensity, catastrophizing, negative affect, or positive affect. In this longitudinal diary study, patients (n = 103) prescribed opioid therapy completed daily diaries for 14 consecutive days. Diaries assessed a host of pain, psychological, and opioid-related variables. The hedonic and calming effects of opioids were not significantly associated with any type of opioid misuse behavior. However, greater hedonic and calming effects were associated with heightened reports of opioid craving (both P's < 0.005). Analyses revealed that these associations were moderated by patients' daily levels of pain intensity, catastrophizing, and negative affect (all P's < 0.001). Results from this study provide valuable new insights into our understanding of factors that may contribute to opioid craving among patients with chronic pain who are prescribed long-term opioid therapy. The implications of our findings for the management of patients with chronic pain are discussed.

Abstract
Young adults exhibit greater sensitivity than adults to nicotine reinforcement, and Attention Deficit Hyperactivity Disorder (ADHD) increases the risk for early-onset smoking. We investigated the correlation between ADHD Self-Report Scale (ASRS) scores and smoking, evaluated the prevalence of ADHD symptomatology (not diagnoses) in smokers and non-smokers and its comorbidity with benzodiazepine and gambling addictions. A total of 389 young adults from 14 schools in Northern Italy fill out a survey and the Adult ADHD Self-Report Scale (ASRS). A total of 15.2% of subjects tested positive at the ASRS, which correlated with smoking; moreover, smokers had twice the probability of testing positive at the ASRS. ADHD symptomatology, especially when comorbid with tobacco abuse, is an important condition to monitor because early nicotine exposure could be a gateway for other addictive behaviors.

Abstract
Smoking is considered the most critical modifiable factor with regard to lung cancer and remains a public health concern in many countries, including Vietnam, which is among those countries with the highest tobacco consumption rates in the world. This study has examined the impact of national telephone counselling for smoking cessation and has identified the factors associated with the impact of the quitline among male callers in Vietnam. A randomized cross-sectional survey of 469 smokers who sought smoking cessation services via the national quitline was performed from September 2015 to May 2016. The primary outcomes were measured by a self-reported quit rate at the time of assessment, 7 day point prevalence abstinence (PA), 6 month prolonged PA, service satisfaction, and level of motivation. Among the participants, 31.6% were abstinent, and 5.1% of participants successfully stopped smoking and did not need to seek quitline support. Most of the clients were satisfied with the quality of service (88.5%), felt more confident about quitting (74.3%), and took early action via their first quit attempt (81.7%); 18.3% reported a more than 7 day abstinence period at the time of survey. The primary reasons for smoking relapse were surrounding smoking environments (51.6%) and craving symptoms (44.1%). Future smoking cessation efforts should focus on improving the quality of quitline services, client satisfaction, and developing a tailored program and counseling targeting smokers with specific characteristics, especially ones experiencing chronic diseases.

[PMID: 29852054 PMCID: PMC6353172 DOI: 10.1002/14651858.cd000146.pub5] [Citation(s) in RCA: 234] [Impact Index Per Article: 39.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/09/2022]
Abstract
BACKGROUND Nicotine replacement therapy (NRT) aims to temporarily replace much of the nicotine from cigarettes to reduce motivation to smoke and nicotine withdrawal symptoms, thus easing the transition from cigarette smoking to complete abstinence. OBJECTIVES To determine the effectiveness and safety of nicotine replacement therapy (NRT), including gum, transdermal patch, intranasal spray and inhaled and oral preparations, for achieving long-term smoking cessation, compared to placebo or 'no NRT' interventions. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group trials register for papers mentioning 'NRT' or any type of nicotine replacement therapy in the title, abstract or keywords. Date of most recent search is July 2017. SELECTION CRITERIA Randomized trials in people motivated to quit which compared NRT to placebo or to no treatment. We excluded trials that did not report cessation rates, and those with follow-up of less than six months, except for those in pregnancy (where less than six months, these were excluded from the main analysis). We recorded adverse events from included and excluded studies that compared NRT with placebo. Studies comparing different types, durations, and doses of NRT, and studies comparing NRT to other pharmacotherapies, are covered in separate reviews. DATA COLLECTION AND ANALYSIS Screening, data extraction and 'Risk of bias' assessment followed standard Cochrane methods. The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. We calculated the risk ratio (RR) for each study. Where appropriate, we performed meta-analysis using a Mantel-Haenszel fixed-effect model. MAIN RESULTS We identified 136 studies; 133 with 64,640 participants contributed to the primary comparison between any type of NRT and a placebo or non-NRT control group. The majority of studies were conducted in adults and had similar numbers of men and women. People enrolled in the studies typically smoked at least 15 cigarettes a day at the start of the studies. We judged the evidence to be of high quality; we judged most studies to be at high or unclear risk of bias but restricting the analysis to only those studies at low risk of bias did not significantly alter the result. The RR of abstinence for any form of NRT relative to control was 1.55 (95% confidence interval (CI) 1.49 to 1.61). The pooled RRs for each type were 1.49 (95% CI 1.40 to 1.60, 56 trials, 22,581 participants) for nicotine gum; 1.64 (95% CI 1.53 to 1.75, 51 trials, 25,754 participants) for nicotine patch; 1.52 (95% CI 1.32 to 1.74, 8 trials, 4439 participants) for oral tablets/lozenges; 1.90 (95% CI 1.36 to 2.67, 4 trials, 976 participants) for nicotine inhalator; and 2.02 (95% CI 1.49 to 2.73, 4 trials, 887 participants) for nicotine nasal spray. The effects were largely independent of the definition of abstinence, the intensity of additional support provided or the setting in which the NRT was offered. A subset of six trials conducted in pregnant women found a statistically significant benefit of NRT on abstinence close to the time of delivery (RR 1.32, 95% CI 1.04 to 1.69; 2129 participants); in the four trials that followed up participants post-partum the result was no longer statistically significant (RR 1.29, 95% CI 0.90 to 1.86; 1675 participants). Adverse events from using NRT were related to the type of product, and include skin irritation from patches and irritation to the inside of the mouth from gum and tablets. Attempts to quantitatively synthesize the incidence of various adverse effects were hindered by extensive variation in reporting the nature, timing and duration of symptoms. The odds ratio (OR) of chest pains or palpitations for any form of NRT relative to control was 1.88 (95% CI 1.37 to 2.57, 15 included and excluded trials, 11,074 participants). However, chest pains and palpitations were rare in both groups and serious adverse events were extremely rare. AUTHORS' CONCLUSIONS There is high-quality evidence that all of the licensed forms of NRT (gum, transdermal patch, nasal spray, inhalator and sublingual tablets/lozenges) can help people who make a quit attempt to increase their chances of successfully stopping smoking. NRTs increase the rate of quitting by 50% to 60%, regardless of setting, and further research is very unlikely to change our confidence in the estimate of the effect. The relative effectiveness of NRT appears to be largely independent of the intensity of additional support provided to the individual. Provision of more intense levels of support, although beneficial in facilitating the likelihood of quitting, is not essential to the success of NRT. NRT often causes minor irritation of the site through which it is administered, and in rare cases can cause non-ischaemic chest pain and palpitations.

Abstinence-induced withdrawal severity among adolescent smokers with and without ADHD: disentangling effects of nicotine and smoking reinstatement. Psychopharmacology (Berl) 2018; 235:169-178.

Abstract
RATIONALE Individuals with attention deficit hyperactivity disorder (ADHD) start smoking earlier, are more likely to progress to nicotine dependence, and have a more difficult time quitting smoking compared to their non-ADHD peers. Little is known about the underlying behavioral mechanisms associated with this increased risk, particularly at the adolescent stage. OBJECTIVE This study aimed to assess the effects of overnight nicotine abstinence and smoking reinstatement on subjective withdrawal states in adolescent smokers with and without ADHD. METHODS Adolescent daily smokers (27 with ADHD and 17 without ADHD) completed three experimental sessions: (1) a placebo patch followed by smoking a nicotine cigarette, (2) placebo patch followed by smoking a nicotine-free cigarette, and (3) nicotine patch followed by smoking a nicotine-free cigarette. Subjects abstained overnight before each session, and patches were administered 45 min before smoking. The primary outcome measure was a smoking withdrawal symptom questionnaire. RESULTS ADHD smokers experienced greater difficulty concentrating and impatience/restlessness during abstinence than non-ADHD smokers. Smoking a cigarette improved abstinence-induced difficulty concentrating and restlessness, regardless of its nicotine content, and regardless of whether transdermal nicotine was received or not. CONCLUSIONS Thus, sensorimotor aspects of smoking, rather than nicotine itself, appeared to relieve withdrawal. Although ADHD smokers report greater withdrawal symptoms than non-ADHD smokers, they responded strongly to the sensorimotor aspects of smoking during withdrawal. These findings suggest that even lighter, adolescent smokers with ADHD are vulnerable to smoking progression through altered smoking abstinence and withdrawal relief processes.

Abstract
INTRODUCTION Four post-hoc analyses of prior trials found smokers using nicotine patch following a lapse were less likely to progress to relapse compared to those using a placebo patch following a lapse. We attempted a conceptual replication test of these results via a randomized trial of instructions to continue vs. stop nicotine patch after a lapse. METHODS Smokers trying to quit (n=701) received nicotine patch (21/14/7mg) and brief phone counseling (six 15-min sessions). We randomized smokers to receive instructions for and rationale for stopping vs. continuing patch after a lapse. The messages were repeated before and after cessation and following lapses via counseling, phone and written instructions. RESULTS Among those who lapsed, those told to Continue Patch did not have a greater incidence of 7-day abstinence at 4months (primary outcome) than those told to Discontinue Patch (51% vs. 46%). Most (81%) participants in the Discontinue condition stopped patch for only 1-2days and then resumed abstinence and patch use. Analyses based on all participants randomized were similar. Adverse events were as expected and did not differ between conditions. CONCLUSION Instructions to continue nicotine patch after a lapse did not increase return to abstinence. These negative results may have occurred because actual use of patch after a lapse was similar in the two conditions. Also, allowing patch use while smoking may have reduced motivation to stay abstinent.

Abstract
RATIONALE One third of US smokers are intermittent smokers (ITS) who do not smoke daily. Unlike daily smokers (DS), whose smoking is negatively reinforced by withdrawal relief, ITS may be motivated by immediate positive reinforcement. In contrast, incentive salience theory posits hypothesis that "liking" of drug effects fades in established users, such as DS. OBJECTIVE This study aims to compare ITS' and DS' hedonic responses to smoking. METHODS Participants were 109 ITS (smoking 4-27 days/month) and 52 DS (smoking daily 5-25 cigarettes/day), aged ≥21, smoking ≥3 years, and not quitting smoking. For 3 weeks, participants engaged in ecological momentary assessment, carrying an electronic diary that asked them to rate their most recent smoking experience on 0-100 visual analog scales (satisfaction, enjoyment [averaged as "pleasure"], feeling sick, feeling a "rush," enjoying upper respiratory sensations, and immediate craving relief). Hierarchical random effect regression analyzed 4476 ratings. RESULTS ITS found smoking pleasurable (mean = 69.7 ± 1.7 [SE]) but significantly less so than DS did (77.6 ± 2.3; p < 0.006). ITS also reported more aversive response (ITS 18.2 ± 1.4, DS 11.6 ± 2.0; p < 0.007). Even though ITS are more likely to smoke at bars/restaurants, when drinking alcohol, or when others were present, they did not report more pleasure in these settings (compared to DS). More extensive smoking experience was unrelated to craving or smoking effects among DS, but predicted greater craving, greater pleasure, and less aversion among ITS. CONCLUSIONS The findings were largely inconsistent with incentive-salience models of drug use.

Naltrexone moderates the relationship between cue-induced craving and subjective response to methamphetamine in individuals with methamphetamine use disorder. Psychopharmacology (Berl) 2017; 234:1997-2007.

Abstract
RATIONALE Reductions in cue-induced craving and subjective response to drugs of abuse are commonly used as initial outcome measures when testing novel medications for the treatment of addiction. Yet neither the relationship between these two measures at the individual level nor the moderating effects of pharmacotherapies on this relationship has been examined. OBJECTIVE This secondary data analysis sought to examine (1) the predictive relationship between cue-induced craving and subsequent acute subjective response to methamphetamine (MA) and (2) whether the opioid-receptor antagonist naltrexone moderated this association in a sample of non-treatment-seeking individuals who met DSM-IV criteria for MA use disorder (abuse or dependence). METHODS Participants (n = 30) completed two 4-day medication regimens (oral naltrexone 50 mg or placebo, in a randomized, counterbalanced, and double-blind fashion). On day 4 of each medication regimen, participants completed a cue-reactivity paradigm followed by intravenous MA administration. Methamphetamine craving was assessed after the cue-reactivity paradigm, and subjective response to MA was assessed during MA infusion. RESULTS Cue-induced craving for MA was positively associated with post-infusion subjective MA effects, including positive (i.e., stimulation, good effects, feel drug, high), negative (i.e., anxious and depressed), and craving-related (i.e., want more, would like access to drug, crave) responses. Naltrexone, vs. placebo, significantly reduced the association between cue-induced craving and positive subjective response to MA. CONCLUSIONS The findings indicate that naltrexone moderates the predictive relationship between cue-induced craving and positive subjective effects of MA, thereby suggesting a behavioral mechanism by which naltrexone may be efficacious in treating MA use disorder.

Abstract
There is a strong association between cigarette smoking and alcohol use at the epidemiological, behavioral, and molecular levels, and this co-use creates substantial impediments to smoking cessation among smokers who are also heavy drinkers. Compared with individuals who only smoke, those who both drink and smoke heavily experience more severe health consequences and have greater difficulty in quitting smoking. During smoking abstinence, greater alcohol use is associated with decreased odds of smoking cessation, and smokers are substantially more likely to experience a smoking lapse during drinking episodes. As heavy drinking smokers are less responsive to the currently available pharmacological treatments, this subgroup of high-risk substance users possesses a unique clinical profile and treatment needs. Thus, treatment development for heavy drinking smokers represents a significant and understudied research area within the field of smoking cessation. This review will briefly describe findings from epidemiological, behavioral, and molecular studies illustrating alcohol and tobacco co-use and identify how the behavioral and neurobiological mechanisms underlying the interaction of alcohol and nicotine may inform the development of targeted treatments for this unique population of smokers.

Abstract
Evidence highlights that an acute bout of exercise can contribute to reductions in cravings and withdrawal symptoms. However, it is unknown how low in intensity or movement one can go before these effects no longer exist. The current study examined if exercise imagery could contribute to reductions in smoking cravings and withdrawal symptoms after a short period of abstinence (CO≤6ppm). Regular smokers (N = 29) were randomized into one of three treatment groups: exercise imagery, moderate intensity exercise, or control. Each completed questionnaires including: the Strength of Desire to Smoke item (primary outcome) and the Mood and Physical Symptoms Scale (Secondary outcomes) pre- and post-treatment. A 3 (Condition) by 2 (Time) repeated measures ANOVA showed a medium non-significant interaction effect (partial η2 = .06) favouring the exercise group for reductions in desire to smoke. A large significant interaction effect (partial η2 = .24) was found for tension. Medium-to-large non-significant interaction effects favouring the exercise group were found for various withdrawal symptoms. These data, taken together, suggest that exercise imagery is not as powerful as moderate intensity exercise in reducing cravings and withdrawal symptoms following temporary abstinence. Implications and future directions are discussed.

Abstract
Background There is substantial scope for improvement in the current arsenal of smoking cessation methods and techniques: even when front-line cessation treatments are utilized, smokers are still more likely to fail than to succeed. Studies testing the incremental benefit of using nicotine patch for 1–4 weeks prior to quitting have shown pre-quit nicotine patch use produces a robust incremental improvement over standard post-quit patch treatment. The primary objective of the current study is to test the mechanism of action of two pre-quit smoking cessation medications—varenicline and nicotine patch—in order to learn how best to optimize these pre-quit treatments. Methods/Design The study is a three group, randomized, open-label controlled clinical trial. Participants (n = 216 interested quitters) will be randomized to receive standard patch treatment (10 weeks of patch starting from a designated quit day), pre-quit patch treatment (two weeks of patch treatment prior to a quit day, followed by 10 weeks post-quit treatment) or varenicline (starting two weeks prior to quit day followed by 10 weeks post-quit). Participants will use study-specific modified smart-phones to monitor their smoking, withdrawal symptoms, craving, mood and social situations in near real-time over four weeks; two weeks prior to an assigned quit date and two weeks after this date. Smoking and abstinence will be assessed at regular study visits and biochemically verified. Discussion Understanding how nicotine patches and varenicline influence abstinence may allow for better tailoring of these treatments to individual smokers.

Abstract
Withdrawal-based theories of addiction hypothesize that motivation to reinstate drug use following acute abstinence is mediated by withdrawal symptoms. Experimental tests of this hypothesis in the tobacco literature are scant and may be subject to methodological limitations. This study utilized a robust within-subject laboratory experimental design to investigate the extent to which composite tobacco withdrawal symptomatology level and 3 unique withdrawal components (i.e., low positive affect, negative affect, and urge to smoke) mediated the effect of smoking abstinence on motivation to reinstate smoking. Smokers (≥10 cigarettes per day; N = 286) attended 2 counterbalanced sessions at which abstinence duration was differentially manipulated (1 hr vs. 17 hr). At both sessions, participants reported current withdrawal symptoms and subsequently completed a task in which they were monetarily rewarded proportional to the length of time they delayed initiating smoking, with shorter latency reflecting stronger motivation to reinstate smoking. Abstinence reduced latency to smoking initiation and positive affect and increased composite withdrawal symptom level, urge, and negative affect. Abstinence-induced reductions in latency to initiating smoking were mediated by each withdrawal component, with stronger effects operating through urge. Combined analyses suggested that urge, negative affect, and low positive affect operate through empirically unique mediational pathways. Secondary analyses suggested similar effects on smoking quantity, few differences among specific urge and affect subtypes, and that dependence amplifies some abstinence effects. This study provides the first experimental evidence that within-person variation in abstinence impacts motivation to reinstate drug use through withdrawal. Urge, negative affect, and low positive affect may reflect unique withdrawal-mediated mechanisms underlying tobacco addiction.

Abstract
OBJECTIVE The authors tested whether clonidine blocks stress-induced seeking of heroin and cocaine. The study was also intended to confirm translational findings from a rat model of drug relapse by using ecological momentary assessment of patients' stress to test hypotheses about clonidine's behavioral mechanism of action. METHOD The authors conducted a randomized double-blind placebo-controlled clinical trial with 208 opioid-dependent patients at an outpatient buprenorphine clinic. The 118 participants (57%) who maintained abstinence during weeks 5-6 were continued on buprenorphine and randomly assigned to receive clonidine (N=61) or placebo (N=57) for 14 weeks. Urine was tested thrice weekly. Lapse was defined as any opioid-positive or missed urine test, and relapse as two or more consecutive lapses. Time to lapse and relapse were examined with Cox regressions; longest period of abstinence was examined with a t test, and ecological momentary assessment data were examined with generalized linear mixed models. RESULTS In an intent-to-treat analysis, clonidine produced the longest duration (in consecutive days) of abstinence from opioids during the intervention phase (34.8 days [SD=3.7] compared with 25.5 days [SD=2.7]; Cohen's d=0.38). There was no group difference in time to relapse, but the clonidine group took longer to lapse (hazard ratio=0.67, 95% CI=0.45-1.00). Ecological momentary assessment showed that daily-life stress was partly decoupled from opioid craving in the clonidine group, supporting the authors' hypothesized mechanism for clonidine's benefits. CONCLUSIONS Clonidine, a readily available medication, is useful in opioid dependence not just for reduction of withdrawal signs, but also as an adjunctive maintenance treatment that increases duration of abstinence. Even in the absence of physical withdrawal, it decouples stress from craving in everyday life.

Abstract
INTRODUCTION The positive emotional and sensory expectancies of cigarette smoking include improved cognitive abilities, positive affective states, and pleasurable sensorimotor sensations. This paper describes development of Positive Emotional and Sensory Expectancies of Smoking item banks that will serve to standardize the assessment of this construct among daily and nondaily cigarette smokers. METHODS Data came from daily (N = 4,201) and nondaily (N =1,183) smokers who completed an online survey. To identify a unidimensional set of items, we conducted item factor analyses, item response theory analyses, and differential item functioning analyses. Additionally, we evaluated the performance of fixed-item short forms (SFs) and computer adaptive tests (CATs) to efficiently assess the construct. RESULTS Eighteen items were included in the item banks (15 common across daily and nondaily smokers, 1 unique to daily, 2 unique to nondaily). The item banks are strongly unidimensional, highly reliable (reliability = 0.95 for both), and perform similarly across gender, age, and race/ethnicity groups. A SF common to daily and nondaily smokers consists of 6 items (reliability = 0.86). Results from simulated CATs indicated that, on average, less than 8 items are needed to assess the construct with adequate precision using the item banks. CONCLUSIONS These analyses identified a new set of items that can assess the positive emotional and sensory expectancies of smoking in a reliable and standardized manner. Considerable efficiency in assessing this construct can be achieved by using the item bank SF, employing computer adaptive tests, or selecting subsets of items tailored to specific research or clinical purposes.

Abstract
It is important to characterize the learning processes governing tobacco-seeking in order to understand how best to treat this behavior. Most drug learning theories have adopted a Pavlovian framework wherein the conditioned response is the main motivational process. We favor instead a hierarchical instrumental decision account, wherein expectations about the instrumental contingency between voluntary tobacco-seeking and the receipt of nicotine reward determines the probability of executing this behavior. To support this view, we review titration and nicotine discrimination research showing that internal signals for deprivation/satiation modulate expectations about the current incentive value of smoking, thereby modulating the propensity of this behavior. We also review research on cue-reactivity which has shown that external smoking cues modulate expectations about the probability of the tobacco-seeking response being effective, thereby modulating the propensity of this behavior. Economic decision theory is then considered to elucidate how expectations about the value and probability of response-nicotine contingency are integrated to form an overall utility estimate for that option for comparison with qualitatively different, nonsubstitute reinforcers, to determine response selection. As an applied test for this hierarchical instrumental decision framework, we consider how well it accounts for individual liability to smoking uptake and perseveration, pharmacotherapy, cue-extinction therapies, and plain packaging. We conclude that the hierarchical instrumental account is successful in reconciling this broad range of phenomenon precisely because it accepts that multiple diverse sources of internal and external information must be integrated to shape the decision to smoke.

Abstract
RATIONALE During a smoking quit attempt, a single smoking lapse is highly predictive of future relapse. While several risk factors for a smoking lapse have been identified during clinical trials, a laboratory model of lapse was until recently unavailable and, therefore, it is unclear whether these characteristics also convey risk for lapse in a laboratory environment. OBJECTIVES The primary study goal was to examine whether real-world risk factors of lapse are also predictive of smoking behavior in a laboratory model of smoking lapse. METHODS After overnight abstinence, 77 smokers completed the McKee smoking lapse task, in which they were presented with the choice of smoking or delaying in exchange for monetary reinforcement. Primary outcome measures were the latency to initiate smoking behavior and the number of cigarettes smoked during the lapse. Several baseline measures of smoking behavior, mood, and individual traits were examined as predictive factors. RESULTS Craving to relieve the discomfort of withdrawal, withdrawal severity, and tension level were negatively predictive of latency to smoke. In contrast, average number of cigarettes smoked per day, withdrawal severity, level of nicotine dependence, craving for the positive effects of smoking, and craving to relieve the discomfort of withdrawal were positively predictive of number of cigarettes smoked. CONCLUSIONS The results suggest that real-world risk factors for smoking lapse are also predictive of smoking behavior in a laboratory model of lapse. Future studies using the McKee lapse task should account for between subject differences in the unique factors that independently predict each outcome measure.

Abstract
RATIONALE AND OBJECTIVES Patches are traditionally started on the day a quit attempt begins. Recently, a number of studies have established that the patch's effectiveness is improved by starting the treatment before quitting [pre-quit patch (PQP) use]. In an exploratory study, we investigate a proposed mechanism through which PQP use might promote abstinence: that PQP reduces satisfaction with smoking (either directly or via craving), which in turn leads to reduction and that smoking reduction promotes abstinence. METHODS Fifty-seven interested quitters used handheld computers to monitor their smoking satisfaction, withdrawal and smoking in real time for 17 days, leading up to a quit attempt. All participants received 21 mg/24 h patches for 2 weeks before and for up to 10 weeks after quitting. Carbon dioxide (CO)-verified 28-day abstinence was assessed. RESULTS During PQP treatment, participants reported significant reductions in both the satisfaction gained from smoking (p < 0.001) and their daily cigarette consumption (p < 0.001). Craving did not decrease; however, there was an interaction between time and nicotine dependence; craving decreased only among low dependent participants. Multilevel structural equation modelling revealed a direct effect of satisfaction on smoking rate. Craving did not mediate this relationship. Smoking reduction during the PQP treatment phase was not significantly associated with abstinence. CONCLUSIONS The real-time data collection protocol utilised allowed for a fine-grained examination of smoking during PQP treatment. The results suggest that the reduction in daily cigarette smoking typically observed during PQP treatment is due to reductions in satisfaction with smoking. Unlike previous studies, however, smoking reduction was not significantly related to later abstinence, even though the odds ratio was comparably. Potential clinical implications of these findings are discussed.

Abstract
Background Studies all over the world reported that smoking relapses occur during the first two weeks after a quit date. The current study aimed to assess the impact of the additional phone calls counselling during the first month on the abstinence rate at 3 and 6 months after quit date among smokers in Penang, Malaysia. Methods The study was conducted at Quit Smoking Clinic of two major hospitals in Penang, Malaysia. All the eligible smokers who attended the clinics between February 1st and October 31st 2012 were invited. Participants were randomly assigned by using urn design method either to receive the usual care that followed in the clinics (control) or the usual care procedure plus extra counselling sessions through phone calls during the first month of quit attempt (intervention). Results Participants in our cohort smoked about 14 cigarettes per day on average (mean = 13.78 ± 7.0). At 3 months, control group was less likely to quit smoking compared to intervention group (36.9% vs. 46.7%, verified smoking status) but this did not reach statistical significance (OR = 0.669; 95% CI = 0.395-1.133, P = 0.86). However, at 6 months, 71.7% of the intervention group were successfully quit smoking (bio-chemically verified) compared to 48.6% of the control group (P < 0.001). The control group were significantly less likely to quit smoking (OR = 0.375; 95% CI = 0.217-0.645, P < 0.001). Conclusions Smoking cessation intervention consisting of phone calls counselling delivered during the first month of quit attempt revealed significantly higher abstinence rates compared with a standard care approach. Therefore, the additional counselling in the first few weeks after stop smoking is a promising treatment strategy that should be evaluated further. Trial registration TCTR20140504001

Abstract
A number of smoking cessation pharmacotherapies have led to increases in quitting and thus to significant benefits to public health. Among existing medications, nicotine replacement therapy (NRT) has been available the longest, has the largest literature base in support, and is the only option for over-the-counter access. While the short-term efficacy of NRT is well documented in clinical trials, long-term abstinence rates associated with using NRT are modest, as most smokers will relapse. This literature review examines emerging clinical strategies to improve NRT efficacy. After an initial overview of NRT and its FDA-approved indications for use, we review randomized trials in which clinical delivery of NRT was manipulated and tested, in an attempt to enhance efficacy, through (1) duration of use (pre-quit and extended use), (2) amount of use (high-dose and combination NRT), (3) tailoring to specific smoker groups (genotype and phenotype), or (4) use of NRT for novel purposes (relapse prevention, temporary abstinence, cessation induction). Outcomes vary within and across topic area, and we highlight areas that offer stronger promise. Combination NRT likely represents the most promising strategy moving forward; other clinical strategies offer conflicting evidence but deserve further testing (pre-quit NRT or tailored treatment) or offer potential utility but are in need of further, direct tests. Some areas, though based on a limited set of studies, do not offer great promise (high-dose and extended treatment NRT). We conclude with a brief discussion of emergent NRT products (e.g., oral nicotine spray, among others), which may ultimately offer greater efficacy than current formulations. In order to further lower the prevalence of smoking, novel strategies designed to optimize NRT efficacy are needed.

Abstract
INTRODUCTION Schizophrenia is associated with a high prevalence of cigarette smoking. The aims of this study were to compare smokers with schizophrenia (SS) and control smokers without psychiatric illness (CS) on (a) cigarette craving and nicotine withdrawal symptom severity during a 72-hr smoking abstinence period; (b) nicotine reinforcement, before and after abstinence; and (c) latency to smoking lapse following abstinence. We also explored mediators of smoking lapse in SS and CS. METHODS SS (n = 28) and CS (n = 27) underwent a nicotine versus denicotinized cigarette puff choice task before and after a 72-hr period of smoking abstinence that was experimentally controlled by providing cash reinforcement contingent on biochemical verification of abstinence. Twenty-four hours after the second choice task, participants could receive a low-value reinforcer if they had continued to abstain since the previous day. Those who remained abstinent were recontacted a week later to determine time of their smoking lapse. RESULTS SS reported more severe cigarette craving and nicotine withdrawal symptoms throughout the 72-hr abstinence period, had greater nicotine preference after abstinence, and lapsed back to smoking significantly sooner than CS. The relationship between group and smoking lapse latency was mediated by baseline depression and nicotine withdrawal symptom severity but not by effects of abstinence on craving or nicotine reinforcement. CONCLUSIONS Overall, these results indicate that negative affect is a key contributor to poor smoking cessation outcomes among those with schizophrenia.

Abstract
BACKGROUND Little is known about the factors that drive the association between point-of-sale marketing and behavior, because methods that directly link individual-level use outcomes to real-world point-of-sale exposure are only now beginning to be developed. PURPOSE Daily outcomes during smoking cessation were examined as a function of both real-time geospatial exposure to point-of-sale tobacco (POST) and subjective craving to smoke. METHODS Continuous individual geospatial location data collected over the first month of a smoking-cessation attempt in 2010-2012 (N=475) were overlaid on a POST outlet geodatabase (N=1060). Participants' mobility data were used to quantify the number of times they came into contact with a POST outlet. Participants recorded real-time craving levels and smoking status via ecological momentary assessment (EMA) on cellular telephones. RESULTS The final data set spanned a total of 12,871 days of EMA and geospatial tracking. Lapsing was significantly more likely on days with any POST contact (OR=1.19, 95% CI=1.18, 1.20), and increasingly likely as the number of daily POST contacts increased (OR=1.07, 95% CI=1.06, 1.08). Overall, daily POST exposure was significantly associated with lapsing when craving was low (OR=1.22, 95% CI=1.20, 1.23); high levels of craving were more directly associated with lapse outcomes. CONCLUSIONS These data shed light on the way mobility patterns drive a dynamic interaction between individuals and the POST environment, demonstrating that quantification of individuals' exposure to POST marketing can be used to identify previously unrecognized patterns of association among individual mobility, the built environment, and behavioral outcomes.

Abstract
The role of The Transtheoretical Model (TTM) in predicting relapse is limited. We aimed to assess whether this model can be utilised to predict relapse during the action stage. The participants included 120 smokers who had abstained from smoking for at least 24 hours following two Malaysian universities' smoking cessation programme. The smokers who relapsed perceived significantly greater advantages related to smoking and increasing doubt in their ability to quit. In contrast, former smokers with greater self-liberation and determination to abstain were less likely to relapse. The findings suggest that TTM can be used to predict relapse among quitting smokers.

Abstract
BACKGROUND/OBJECTIVES Cigarette smoking remains the leading cause of preventable death in the United States with the vast majority of adult smokers starting prior to the age of 18. Despite the public health relevance and implications of studying smoking in adolescents, little is known about the initiation of quit attempts, the process of relapse, and the most efficacious treatment interventions in this high-risk and underserved population. Issues such as retention in research studies and accuracy of self-reports have prompted investigators to explore innovative technology-based systems to integrate into treatment studies and services delivery. METHODS This paper will review the remote monitoring of smoking through means of ecological momentary assessment, biochemical verification of smoking verified through video capture, physiological monitoring, and mobile-delivered interventions using self-reported smoking outcomes in adolescents, when applicable. RESULTS Use of remote monitoring methods in adolescent smokers has been limited thus far, though monitoring technology in adults has shown promise for understanding relapse and delivering treatment interventions. CONCLUSIONS Comprehensive technology-based systems that do not rely primarily on self-report to monitor smoking would be a highly fruitful and innovative avenue to explore with adolescent smokers. Technology integration holds great promise to improve health-related research, treatment delivery, cost-effectiveness, and just-in-time interventions, but its novelty comes with unique problems and concerns to be carefully considered.

Abstract
INTRODUCTION Varenicline (Chantix®) is an efficacious first-line medication for smoking cessation. Studies suggest that one mechanism by which varenicline facilitates sustained smoking abstinence is by reducing the likelihood of relapse to smoking when a lapse, or slip, occurs during a quit attempt. The present study extends this line of research by conducting a prospective laboratory study to examine the relapse prevention effects of varenicline following a programmed lapse. METHODS Daily smokers (N = 47) completed a 5-week outpatient study in which they were randomized to receive varenicline or placebo. The first week was a medication induction period that was immediately followed by a 4-week quit attempt. A programmed lapse (2 cigarettes smoked in the laboratory) occurred on the second day of the quit attempt. RESULTS Participants receiving varenicline were slower to relapse and had greater total abstinence rates following lapse exposure. Participants in the varenicline group rated lapse cigarettes lower on measures of reward and intoxication and showed increased behavioral economic demand elasticity for cigarettes (reduced cigarette purchasing at higher prices) compared with those receiving placebo. CONCLUSIONS These results demonstrate a relapse prevention effect of varenicline following smoking lapse exposure and suggest that an attenuation of reward from smoking and the blunting of subjective effects of smoking may underlie and/or contribute to this effect.

Abstract
This study aimed to identify correlates of smoking-cessation failure, a failure to establish abstinence during a quit-smoking attempt. Identifying risk factors for early failure could facilitate the development of tailored interventions to promote cessation. The current study used existing ecological momentary assessment (EMA) data to investigate the extent to which prequit craving, negative affect, and recent smoking were associated with cessation failure in 374 smokers (189, 50.5% female). Subjects were prompted to complete 4-7 real-time reports of craving, negative affect, and recent smoking daily in the four days prior to quitting. Multilevel models of craving and negative affect (mean level, growth, volatility, and association with smoking) were estimated. Results indicated that recent smoking was associated with significantly lower craving among smokers who failed to quit than those who achieved a full day of cessation, but this held only among smokers who reduced smoking by at least 10% in the days preceding the quit attempt. Smokers who failed to quit on the quit day also experienced slower increases in negative affect in the days preceding the quit attempt than did initial abstainers, but delayed quitters and delayed cessation failures did not differ in negative-affect trajectories. These results suggest that successful abstainers and cessation failures can be differentiated by specific dimensions of prequit craving and negative-affect experiences, but the effects hold only in certain circumstances.

Abstract
BACKGROUND The aim of nicotine replacement therapy (NRT) is to temporarily replace much of the nicotine from cigarettes to reduce motivation to smoke and nicotine withdrawal symptoms, thus easing the transition from cigarette smoking to complete abstinence. OBJECTIVES The aims of this review were: To determine the effect of NRT compared to placebo in aiding smoking cessation, and to consider whether there is a difference in effect for the different forms of NRT (chewing gum, transdermal patches, oral and nasal sprays, inhalers and tablets/lozenges) in achieving abstinence from cigarettes. To determine whether the effect is influenced by the dosage, form and timing of use of NRT; the intensity of additional advice and support offered to the smoker; or the clinical setting in which the smoker is recruited and treated. To determine whether combinations of NRT are more likely to lead to successful quitting than one type alone. To determine whether NRT is more or less likely to lead to successful quitting compared to other pharmacotherapies. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group trials register for papers mentioning 'NRT' or any type of nicotine replacement therapy in the title, abstract or keywords. Date of most recent search July 2012. SELECTION CRITERIA Randomized trials in which NRT was compared to placebo or to no treatment, or where different doses of NRT were compared. We excluded trials which did not report cessation rates, and those with follow-up of less than six months. DATA COLLECTION AND ANALYSIS We extracted data in duplicate on the type of participants, the dose, duration and form of nicotine therapy, the outcome measures, method of randomization, and completeness of follow-up. The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. We calculated the risk ratio (RR) for each study. Where appropriate, we performed meta-analysis using a Mantel-Haenszel fixed-effect model. MAIN RESULTS We identified 150 trials; 117 with over 50,000 participants contributed to the primary comparison between any type of NRT and a placebo or non-NRT control group. The risk ratio (RR) of abstinence for any form of NRT relative to control was 1.60 (95% confidence interval [CI] 1.53 to 1.68). The pooled RRs for each type were 1.49 (95% CI 1.40 to 1.60, 55 trials) for nicotine gum; 1.64 (95% CI 1.52 to 1.78, 43 trials) for nicotine patch; 1.95 (95% CI 1.61 to 2.36, 6 trials) for oral tablets/lozenges; 1.90 (95% CI 1.36 to 2.67, 4 trials) for nicotine inhaler; and 2.02 (95% CI 1.49 to 2.73, 4 trials) for nicotine nasal spray. One trial of oral spray had an RR of 2.48 (95% CI 1.24 to 4.94). The effects were largely independent of the duration of therapy, the intensity of additional support provided or the setting in which the NRT was offered. The effect was similar in a small group of studies that aimed to assess use of NRT obtained without a prescription. In highly dependent smokers there was a significant benefit of 4 mg gum compared with 2 mg gum, but weaker evidence of a benefit from higher doses of patch. There was evidence that combining a nicotine patch with a rapid delivery form of NRT was more effective than a single type of NRT (RR 1.34, 95% CI 1.18 to 1.51, 9 trials). The RR for NRT used for a short period prior to the quit date was 1.18 (95% CI 0.98 to 1.40, 8 trials), just missing statistical significance, though the efficacy increased when we pooled only patch trials and when we removed one trial in which confounding was likely. Five studies directly compared NRT to a non-nicotine pharmacotherapy, bupropion; there was no evidence of a difference in efficacy (RR 1.01; 95% CI 0.87 to 1.18). A combination of NRT and bupropion was more effective than bupropion alone (RR 1.24; 95% CI 1.06 to 1.45, 4 trials). Adverse effects from using NRT are related to the type of product, and include skin irritation from patches and irritation to the inside of the mouth from gum and tablets. There is no evidence that NRT increases the risk of heart attacks. AUTHORS' CONCLUSIONS All of the commercially available forms of NRT (gum, transdermal patch, nasal spray, inhaler and sublingual tablets/lozenges) can help people who make a quit attempt to increase their chances of successfully stopping smoking. NRTs increase the rate of quitting by 50 to 70%, regardless of setting. The effectiveness of NRT appears to be largely independent of the intensity of additional support provided to the individual. Provision of more intense levels of support, although beneficial in facilitating the likelihood of quitting, is not essential to the success of NRT.

Abstract
Tobacco smoking causes cardiovascular, respiratory and malignant disease, and stopping smoking is among the key medical interventions to lower the worldwide burden of these disorders. However, the addictive properties of cigarette smoking, including nicotine inhalation, render most quit attempts unsuccessful. Recommended therapies, including combinations of counselling and medication, produce long-term continuous abstinence rates of no more than 30%. Thus, more effective treatment options are needed. An intriguing novel therapeutic concept is vaccination against nicotine. The basic principle of this approach is that, after entering the systemic circulation, a substantial proportion of nicotine can be bound by antibodies. Once bound to antibodies, nicotine is no longer able to cross the blood-brain barrier. As a consequence, the rewarding effects of nicotine are diminished, and relapse to smoking is less likely to occur. Animal studies indicate that antibodies profoundly change the pharmacokinetics of the drug and can interfere with nicotine self-administration and impact on the severity of withdrawal symptoms. To date, five phase I/II clinical trials using vaccines against nicotine have been published. Results have been disappointing in that an increase in quit rates was only observed in small groups of smokers displaying particularly high antibody titres. The failure of encouraging preclinical data to completely translate to clinical studies may be partially explained by shortcomings of animal models of addiction and an incomplete understanding of the complex physiological and behavioural processes contributing to tobacco addiction. This review summarizes the current status of research and suggests some directions for the future development of vaccines against nicotine. Ideally, these vaccines could one day become part of a multifaceted approach to treating tobacco addiction that includes counselling and pharmacotherapy.

Abstract
Relapse to smoking is common after initial abstinence with pharmacotherapy and behavioral support and represents a major clinical challenge. Although mechanisms underlying relapse to smoking have not been elucidated, preclinical studies suggest that glutamate receptors may be involved. We sought to test a selective antagonist of the glycine coagonist site on the glutamate N-methyl-D-aspartate receptor, GW468816, for prevention of relapse in recently abstinent smokers. To do so, we enrolled 264 healthy female smokers in an open 8-week smoking cessation intervention with behavioral therapy and a standard dose of transdermal nicotine replacement therapy with taper and additional gum or lozenge as needed for nicotine withdrawal symptoms. Ninety-eight participants achieved 7-day point prevalence abstinence and were randomized into a 5-week double-blind, placebo-controlled, relapse-prevention trial of GW468816 (200 mg/d) and then followed for 60 days after randomization. There was no effect of treatment on abstinence rates at the end of treatment (χ² [1, n = 96] = 0.168, P = 0.838), on the rates of relapse (χ² [1, n = 98] = 0.031, P = 1.000) or lapse (χ² [1, n = 62] = 0.802, P = 0.423), or on time to relapse (χ² [1, n = 98) = 0.001, P = 0.972). No significant relationships were detected between plasma GW468816 concentrations and abstinence, time to relapse, or self-reported craving. In conclusion, despite promising preclinical data that support the use of a selective NMDA glycine site antagonist for prevention of relapse to smoking, we observed no effect of GW468816 on relapse or lapse rates, time to relapse, or craving compared to placebo.

Abstract
Smoking cessation is a process that unfolds over time and is characterized by intermittent lapses. We used parametric recurrent event survival analyses to better understand the dynamic relationship between a set of Abstinence Violation Effect (AVE, Marlatt & Gordon, 1985) responses to lapsing and subsequent lapse-relapse progression. Participants were 203 smokers who achieved abstinence and responded to items assessing three core components of the AVE (internal attribution, abstinence self-efficacy and guilt) following a total of 1,001 lapse episodes in near real time. Neither self-blame, self-efficacy, nor guilt following participants' first lapse predicted relapse. Controlling for responses to their first lapse, responses to each additional lapse did prospectively predict lapse progression, such that drops in self-efficacy were associated with accelerated progression to a subsequent lapse (HR = 1.09, CI = 1.02-1.15), while increases in internal attributions of blame actually protected against lapsing (HR = 0.98, CI = 0.97-0.99). Treatment with nicotine patches slowed recurrent lapse progression (HR = 0.58, CI = 0.48-0.70), but this effect dissipated over multiple lapses, and was moderated by elevated ratings of postlapse guilt (HR = 1.08, CI = 1.01-1.18), which predicted accelerated progression within the active patch group, while protecting against lapse in the placebo group. Results highlight the dynamic nature of lapse responses during smoking cessation, indicating that self-efficacy predicts progression from one lapse to the next, while attributions of self-blame and guilt influenced progression in unexpected ways.

Abstract
Among chronic smokers, individual differences in subjective reactions to smoking may characterize important facets of nicotine dependence that relate to abstinence-induced craving, withdrawal symptom profiles, and risk for relapse. Although the negative reinforcing properties of smoking have achieved prominent positions in models of relapse (Baker, Brandon, & Chassin, 2004), vulnerability to relapse risk may also arise from seeking positive reinforcement from smoking (Shiffman & Kirchner, 2009). In this study, 183 cessation-motivated smokers provided subjective craving, positive and negative reactions to standardized cigarettes following overnight abstinence. Level of craving, negative mood, and positive mood after overnight abstinence were significantly predictive of withdrawal on quit-day. Increased positive reactions to smoking were uniquely predictive of relapse after quitting (Hazard Ratio = 1.22, p < .001). Individual differences in positive reactions to smoking may be important markers of neurobiological systems that promote dependence and interfere with cessation efforts.

Abstract
BACKGROUND FDA-approved labeling for over-the-counter (OTC) nicotine replacement therapy (NRT) limits duration of use to a relatively short period of time (10-12 weeks) and explicitly advises against NRT use while smoking or with additional forms of NRT. OBJECTIVE To consider and summarize evidence accumulated since the OTC label was created regarding the safety and efficacy of longer-term and concomitant use to provide recommendations regarding these uses. METHOD Literature searches were conducted on Medline, journal websites, and Internet search engines, with findings reviewed by six smoking cessation researchers. RESULTS Persistent (i.e., long-term) use of NRT does not appear harmful and self-selected persistent use is primarily driven by concerns about relapse to smoking, not addiction. Similarly, continued use of NRT and tobacco during a lapse or relapse and combination NRT treatment do not appear harmful and appear to enhance efficacy. CONCLUSIONS Persistent users of NRT should be counseled to reduce and stop NRT only when they are not concerned about relapsing to smoking. Use of NRT with return to smoking during a lapse or relapse should not be automatically discontinued. Combination NRT therapy should be considered for all smokers, especially those who are unable to quit smoking using a single form of NRT.

Abstract
Ecological momentary assessment (EMA) is the name applied to any of a range of research methodologies that aim to assess participants in near real time as they go about their regular day-to-day activities. Such methods have particular utility for studying drug use and drug dependence. Using the area of nicotine dependence as a case study, this review highlights how EMA can be used to build upon the findings from more traditional research methods to enhance our understanding of drug use. Particular attention is given to the role that advances in technology have played in the adoption of EMA in drug dependence research.

Abstract
There is a well-established connection between smoking and depression. Depressed individuals are over-represented among smokers, and ex-smokers often experience increased depressive symptoms immediately after stopping smoking. Nicotine in tobacco binds, activates and desensitizes nicotinic acetylcholine receptors (nAChRs), but it is not known whether activation or desensitization is more important for the effects of nicotine on depressive symptoms. Here we review, based on clinical and preclinical studies of nicotinic drugs, the hypothesis that blockade (rather than activation) of neuronal nAChRs might be important for the effects of nicotinic agents on depressive symptoms. The endogenous neurotransmitter for nAChRs is acetylcholine, and the effects of nicotine on depression-like behaviors support the idea that dysregulation of the cholinergic system might contribute to the etiology of major depressive disorder. Thus, pharmacological agents that limit acetylcholine signaling through neuronal nAChRs might be promising for the development of novel antidepressant medications.

Abstract
We sought to determine whether different social, psychological, emotional, and physiological experiences associated with quitting smoking related to people's satisfaction with cessation systematically, and whether the strength of the relations changes at different points during the cessation process and for different people (e.g., optimists). Using data from smokers enrolled in a cessation program, we used mixed models to assess the average longitudinal relation between people's experiences and satisfaction measured at seven time points and whether the relations were moderated by key variables. Eight of nine experiences were related to people's satisfaction (ps < 0.05) and the models accounted for 39-44% of the within-person variance in satisfaction. Current smoking behavior was more strongly related to people's satisfaction during their early efforts to quit, whereas some experiences (e.g., feedback from others) had a stronger relation with satisfaction during people's later efforts to quit or maintain abstinence (ps < 0.05). Individual differences in optimism and prior cessation experience moderated some of the relations (ps < 0.05). The findings mark the first evidence of factors that might influence how people determine their satisfaction with smoking cessation. The implications for tailoring interventions and potentially increasing the likelihood that people maintain abstinence are discussed.

Abstract
RATIONALE Varenicline may aid smoking cessation by attenuating smoking behavior and reward. We compared the effects of varenicline versus placebo on smoking behavior and reward, assessed both prospectively and retrospectively, and related these effects to subsequent success in a brief simulated quit attempt with medication. MATERIALS AND METHODS Smokers (n = 124) with high or low interest in quitting smoking participated in a double-blind crossover study of varenicline versus placebo effects on smoking behavior and reward. In each of two phases, subjects received a week of medication run-up with varenicline (0.5 mg, b.i.d.) or placebo while continuing to smoke, followed the next week by an attempt to quit while on medication. At the end of each run-up week, subjects completed retrospective measures of smoking reward (liking) and number of cigarettes over the prior 24 hrs, and they provided an expired air carbon monoxide (CO) measure. They then completed a prospective session in which they ad lib smoked and rated the rewarding effects of one of their preferred cigarettes while blind to brand. RESULTS Varenicline decreased smoking reward significantly in the prospective assessment, but only marginally in the retrospective assessment. Varenicline did not alter smoking behavior prospectively, but did reduce CO and retrospective report of smoking amount. None of these effects of varenicline predicted subsequent days of abstinence due to varenicline. CONCLUSIONS During medication run-up, varenicline decreases acute smoking reward and may attenuate smoking behavior, but these effects do not appear to directly predict varenicline's influence on smoking abstinence in a short-term test.

Abstract
RATIONALE Negative mood increases smoking reinforcement and may do so to a greater degree in smokers vulnerable to negative mood dysregulation. METHODS Adult smokers (N = 71) without current depression were randomly assigned to one of two smoking conditions (nicotine or denic cigarettes, presented blind) maintained across all sessions. Subjects completed one neutral mood session and four negative mood induction sessions. Negative mood inductions included one each of the following: 1) overnight smoking abstinence, 2) challenging computer task, 3) public speech preparation, 4) watching negative mood slides. In each session, subjects took 4 puffs on their assigned cigarette, rated it for "liking" (reward), and then smoked those cigarettes ad libitum (reinforcement) during continued mood induction. Affect was assessed intermittently before and after smoking. Differences in responses were examined as functions of self-reported history of major depression and levels of distress tolerance and anxiety sensitivity. RESULTS Smoking reinforcement, but not reward or negative affect relief, was greater in all sessions in those with a history of depression and greater after overnight abstinence in those with lower distress tolerance. Reward and affect relief, but not reinforcement, were greater during speech preparation among those high in anxiety sensitivity. CONCLUSIONS Low distress tolerance may enhance acute smoking reinforcement due to abstinence, while depression history may broadly increase acute smoking reinforcement regardless of mood. Neither smoking reward nor affect help explain these individual differences in smoking reinforcement.

Abstract
INTRODUCTION Smokers tend to smoke when experiencing craving, but even within smoking occasions, craving may vary. We examine variations in craving when people were smoking in various real-world situations. METHODS Using Ecological Momentary Assessment, 394 smokers recorded smoking, craving, and smoking context in real time on electronic diaries over 2 weeks of ad libitum smoking. Assessments occurred immediately prior to smoking. Mixed modeling was used to analyze associations between craving and situational variables. RESULTS Craving varied across smoking situations, but the differences were small (<1 on a 0-10 scale). Specifically, craving was higher in smoking situations where smoking was restricted, likely because high craving leads smokers to violate restrictions. Controlling for restrictions, craving was higher when cigarettes were smoked while eating or drinking, were with other people (vs. alone), were in a group of people (vs. other people simply in view), during work (vs. leisure), and during activity (vs. inactivity). In addition, craving was higher for cigarettes smoked early in the day. No differences in craving were observed in relation to drinking alcohol or caffeine (vs. doing anything else), being at work (vs. home), being at a bar or restaurant (vs. all other locations), interacting with others (vs. not interacting), or other people smoking (vs. no others smoking). DISCUSSION Even though most craving reports prior to smoking were high, and situations were thus expected to have little influence on craving, results suggest that some cigarettes are craved more than others across different smoking situations, but differences are small.

Abstract
Ecological momentary assessment (EMA) is particularly suitable for studying substance use, because use is episodic and thought to be related to mood and context. This article reviews EMA methods in substance use research, focusing on tobacco and alcohol use and relapse, where EMA has been most applied. Common EMA designs combine event-based reports of substance use with time-based assessments. Approaches to data organization and analysis have been very diverse, particularly regarding their treatment of time. Compliance with signaled assessments is often high. Compliance with recording of substance use appears good but is harder to validate. Treatment applications of EMA are emerging. EMA captures substance use patterns not measured by questionnaires or retrospective data and holds promise for substance use research.

Abstract
BACKGROUND Tobacco dependence is a chronic, relapsing condition that may require extended treatment. OBJECTIVE To assess whether extended-duration transdermal nicotine therapy increases abstinence from tobacco more than standard-duration therapy in adult smokers. DESIGN Parallel randomized, placebo-controlled trial from September 2004 to February 2008. Participants and all research personnel except the database manager were blinded to randomization. (ClinicalTrials.gov registration number: NCT00364156) SETTING Academic center. PARTICIPANTS 568 adult smokers. INTERVENTION In an unstratified small block-randomization scheme, participants were randomly assigned to standard therapy (Nicoderm CQ [GlaxoSmithKline, Research Triangle Park, North Carolina], 21 mg, for 8 weeks and placebo for 16 weeks) or extended therapy (Nicoderm CQ, 21 mg, for 24 weeks). MEASUREMENTS The primary outcome was biochemically confirmed point-prevalence abstinence at weeks 24 and 52. Secondary outcomes were continuous and prolonged abstinence, lapse and recovery events, cost per additional quitter, and side effects and adherence. RESULTS At week 24, extended therapy produced higher rates of point-prevalence abstinence (31.6% vs. 20.3%; odds ratio, 1.81 [95% CI, 1.23 to 2.66]; P = 0.002), prolonged abstinence (41.5% vs. 26.9%; odds ratio, 1.97 [CI, 1.38 to 2.82]; P = 0.001), and continuous abstinence (19.2% vs. 12.6%; odds ratio, 1.64 [CI, 1.04 to 2.60]; P = 0.032) versus standard therapy. Extended therapy reduced the risk for lapse (hazard ratio, 0.77 [CI, 0.63 to 0.95]; P = 0.013) and increased the chances of recovery from lapses (hazard ratio, 1.47 [CI, 1.17 to 1.84]; P = 0.001). Time to relapse was slower with extended versus standard therapy (hazard ratio, 0.50 [CI, 0.35 to 0.73]; P < 0.001). At week 52, extended therapy produced higher quit rates for prolonged abstinence only (P = 0.027). No differences in side effects and adverse events between groups were found at the extended-treatment assessment. LIMITATION The generalizability of the findings may be limited because participants were smokers without medical comorbid conditions who were seeking treatment, and differences in adherence across treatment groups were detected. CONCLUSION Transdermal nicotine for 24 weeks increased biochemically confirmed point-prevalence abstinence and continuous abstinence at week 24, reduced the risk for smoking lapses, and increased the likelihood of recovery to abstinence after a lapse compared with 8 weeks of transdermal nicotine therapy.

Abstract
RATIONALE Drug cues play an important role in motivating human drug taking, lapse and relapse, but the psychological basis of this effect has not been fully specified. METHOD To clarify these mechanisms, the study measured the extent to which pictorial and conditioned tobacco cues enhanced smoking topography in an ad libitum smoking session simultaneously with cue effects on subjective craving, pleasure and anxiety. RESULTS Both cue types increased the number of puffs consumed and craving, but pleasure and anxiety responses were dissociated across cue type. Moreover, cue effects on puff number correlated with effects on craving but not pleasure or anxiety. Finally, whereas overall puff number and craving declined across the two blocks of consumption, consistent with burgeoning satiety, cue enhancement of puff number and craving were both unaffected by satiety. CONCLUSIONS Overall, the data suggest that cue-elicited drug taking in humans is mediated by an expectancy-based associative learning architecture, which paradoxically is autonomous of the current incentive value of the drug.

Abstract
Addiction involves powerful motivation to engage in an activity repeatedly to an extent that is harmful often accompanied by impaired capacity for self-control. To effectively combat addiction to cigarettes requires an understanding that there are several mechanisms underlying it. The PRIME Theory of motivation aims to provide a model that can encapsulate these mechanisms. It recognises that evolution has led to multiple levels of motivation from basic impulses and inhibitions, through 'motives' (feelings of want and need), to 'evaluations' (beliefs about what is good or bad), and plans (intentions regarding future actions). Self-control involves self-consciously generating motives from evaluations or plans; it requires and depletes mental energy. Nicotine from cigarettes generates the motivation to smoke and undermines self-control by interacting with all of the level of motivation. It: creates stimulus-impulse associations resulting in cue-driven urges; impairs inhibitory control; gives enjoyment resulting in 'wanting' to smoke; it leads to 'nicotine hunger', withdrawal symptoms and beliefs about benefits of smoking (e.g. stress relief) all of which can result in a 'need' to smoke. Evidence is emerging that wanting to smoke (because of enjoyment) is a major deterrent to making quit attempts but does not influence success, while cue-driven impulses to smoke, nicotine hunger and adverse mood and beliefs about the benefits of smoking are important in relapse. Combating cigarette addiction requires attention to all of these factors.

Abstract
Smoking is thought to produce immediate reinforcement, and subjective satisfaction with smoking is thought to influence subsequent smoking. The authors used ecological momentary assessment (A. A. Stone & S. Shiffman, 1994) 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 < .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 were 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.

Abstract
This study aimed to investigate factors predicting lapse among pregnant and non-pregnant women when trying to stop smoking. A total of 40 women, pregnant and non-pregnant, were investigated over a 2-week period when trying to stop smoking. One-quarter of the women lapsed every day. Not being pregnant was a significant predictor for the occurrence of any lapse during the time period, whereas age, number of years of smoking, number of earlier attempts to stop smoking, and number of cigarettes smoked per day did not predict lapse. There was a four times higher risk for lapse in non-pregnant compared with pregnant women. Being pregnant gives an opportunity to help stop smoking with a considerably lower risk of lapse compared with non-pregnant women.

Abstract
Cigarette smoking is a tenacious addiction that is maintained to a significant extent by the reinforcing effects of nicotine. An emerging theme in smoking cessation treatment is the development of methods for interfering with these reinforcing effects. By attenuating nicotine reinforcement, treatments may enhance a smoker's chances of successfully remaining abstinent. Several treatment approaches will be described, including the use of denicotinized cigarettes, nicotine vaccines, nicotinic receptor agonists and antagonists, and modulators of brain reinforcement processes. These techniques highlight the numerous sites along the path between the cigarette and the brain that can be targeted for intervention. In addition to unimodal therapies, treatment combinations will be discussed that might more effectively block cigarette reward and thereby further enhance smoking abstinence.

Abstract
The mechanisms underlying the low smoking cessation rates among smokers with schizophrenia (SS) are unknown. In this laboratory study, we compared the responses of 21 SS and 21 non-psychiatric controls (CS) to manipulations of 5-hour smoking abstinence, transdermal nicotine replacement (0 mg, 21 mg and 42 mg), and in vivo smoking cues. Results indicate that SS were more sensitive than CS to the effects of acute abstinence on carbon monoxide (CO) boost, but not more sensitive to the effects of abstinence on urge levels or withdrawal symptoms. SS and CS did not differ in urge response to in vivo smoking cues, but SS were less consistent in their reactions. These findings suggest that heightened sensitivity to the effects of abstinence on smoke intake may partially account for the low cessation rates experienced by SS, but other potential mechanisms should be explored using behavioral laboratory models.

Abstract
AIM To evaluate the incremental efficacy of starting nicotine patch treatment prior to quitting compared to the current regimen of starting patch treatment on the target quit day. DESIGN AND MEASUREMENTS Meta-analysis of four eligible studies using pre-cessation patch treatment, located by database search and contacts with cessation researchers. The studies all compared starting treatment with nicotine patch prior to the target quit date to starting active treatment at the quit date, some in the context of concurrent mecamylamine treatment. The primary end-point for the analysis was continuous abstinence for at least 28 days assessed at 6 weeks following quit day; 6-month outcomes were also examined. FINDINGS Compared to starting active patch treatment on quit day, pre-cessation treatment with nicotine patches was found to double the odds of quitting. This was true both at 6 weeks [pooled odds ratio (OR) = 1.96, 95% confidence interval (CI): 1.31-2.93] and 6 months (pooled OR = 2.17, 95% CI: 1.46-3.22) treatment outcomes. Mecamylamine co-treatment did not modify these effects. CONCLUSIONS Across the four studies analyzed, pre-cessation patch treatment was found to produce a robust increase in quit rates compared to current regimens starting patch at quit day. Pre-cessation patch use represents a promising innovation in smoking cessation therapy with potential beneficial implications for improved public health by further increasing quitting success.

Abstract
The authors examined the factor structure of the Minnesota Nicotine Withdrawal Scale (MNWS) using confirmatory factor analysis in 3 clinical research samples of smokers trying to quit (N = 723). Three confirmatory factor analytic models, based on previous research, were tested with each of the 3 study samples at multiple points in time. A unidimensional model including all 8 MNWS items was found to be the best explanation of the data. This model produced fair to good internal consistency estimates. Additionally, these data revealed that craving should be included in the total score of the MNWS. Factor scores derived from this single-factor, 8-item model showed that increases in withdrawal were associated with poor smoking outcome for 2 of the clinical studies. Confirmatory factor analyses of change scores showed that the MNWS symptoms cohere as a syndrome over time. Future investigators should report a total score using all of the items from the MNWS.

Abstract
BACKGROUND The aim of nicotine replacement therapy (NRT) is temporarily to replace much of the nicotine from cigarettes to reduce motivation to smoke and nicotine withdrawal symptoms, thus easing the transition from cigarette smoking to complete abstinence. OBJECTIVES The aims of this review were:To determine the effect of NRT compared to placebo in aiding smoking cessation, and to consider whether there is a difference in effect for the different forms of NRT (chewing gum, transdermal patches, nasal spray, inhalers and tablets/lozenges) in achieving abstinence from cigarettes. To determine whether the effect is influenced by the dosage, form and timing of use of NRT; the intensity of additional advice and support offered to the smoker; or the clinical setting in which the smoker is recruited and treated. To determine whether combinations of NRT are more likely to lead to successful quitting than one type alone. To determine whether NRT is more or less likely to lead to successful quitting compared to other pharmacotherapies. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group trials register for papers with 'nicotine' or 'NRT' in the title, abstract or keywords. Date of most recent search July 2007. SELECTION CRITERIA Randomized trials in which NRT was compared to placebo or to no treatment, or where different doses of NRT were compared. We excluded trials which did not report cessation rates, and those with follow up of less than six months. DATA COLLECTION AND ANALYSIS We extracted data in duplicate on the type of participants, the dose, duration and form of nicotine therapy, the outcome measures, method of randomization, and completeness of follow up. The main outcome measure was abstinence from smoking after at least six months of follow up. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. We calculated the risk ratio (RR) for each study. Where appropriate, we performed meta-analysis using a Mantel-Haenszel fixed-effect model. MAIN RESULTS We identified 132 trials; 111 with over 40,000 participants contributed to the primary comparison between any type of NRT and a placebo or non-NRT control group. The RR of abstinence for any form of NRT relative to control was 1.58 (95% confidence interval [CI]: 1.50 to 1.66). The pooled RR for each type were 1.43 (95% CI: 1.33 to 1.53, 53 trials) for nicotine gum; 1.66 (95% CI: 1.53 to 1.81, 41 trials) for nicotine patch; 1.90 (95% CI: 1.36 to 2.67, 4 trials) for nicotine inhaler; 2.00 (95% CI: 1.63 to 2.45, 6 trials) for oral tablets/lozenges; and 2.02 (95% CI: 1.49 to 3.73, 4 trials) for nicotine nasal spray. The effects were largely independent of the duration of therapy, the intensity of additional support provided or the setting in which the NRT was offered. The effect was similar in a small group of studies that aimed to assess use of NRT obtained without a prescription. In highly dependent smokers there was a significant benefit of 4 mg gum compared with 2 mg gum, but weaker evidence of a benefit from higher doses of patch. There was evidence that combining a nicotine patch with a rapid delivery form of NRT was more effective than a single type of NRT. Only one study directly compared NRT to another pharmacotherapy. In this study quit rates with nicotine patch were lower than with the antidepressant bupropion. AUTHORS' CONCLUSIONS All of the commercially available forms of NRT (gum, transdermal patch, nasal spray, inhaler and sublingual tablets/lozenges) can help people who make a quit attempt to increase their chances of successfully stopping smoking. NRTs increase the rate of quitting by 50-70%, regardless of setting. The effectiveness of NRT appears to be largely independent of the intensity of additional support provided to the individual. Provision of more intense levels of support, although beneficial in facilitating the likelihood of quitting, is not essential to the success of NRT.
