Cue reactivity (CR) among smokers exposed to smoking-related stimuli, both proximal (e.g., cigarettes, lighter) and distal (environments, people), has been well-demonstrated.

Previously we have shown that urgency and leakage can be reproduced during urodynamic studies with exposure to personal urgency-related images. Here we investigate the neural signatures associated with such situational triggers to inform potential therapies for reducing reactivity to these personal urgency-related cues among women with situational UUI.

Although clinically recognized as a key symptom of nicotine withdrawal, sleep disturbances are not addressed in the clinical guidelines for nicotine dependence treatment. Unfortunately, Nicotine Replacement Therapy (NRT) and other pharmacologic interventions do not attenuate withdrawal-provoked sleep disturbances, with several even exacerbating sleep disruption.

To better understand the extent of this phenomenon, and how best to reduce its impact, we tested ways to recreate these situational cues in a controlled environment and obtain cue reactivity measures.
Methods: We developed a standardized set of urgency cue scenarios from interviews with sufferers of situational urgency urinary incontinence (UUI), personalized urgency, and safe cue sets consisting of photographs of specific locations, and measurements of cue reactivity during computer-based presentation and urodynamic monitoring.
Introduction: A mandated reduction in the nicotine content of cigarettes may decrease smoking, but also increase demand for other nicotine products. The present study tested the impact of smoking cigarettes with very low nicotine content and concurrent use of a transdermal nicotine patch.
Study Design: A balanced 2 × 2 factorial randomized clinical trial investigating the impact of cigarette nicotine content (double-blind, very low nicotine content versus normal nicotine content) and use of a transdermal nicotine patch (open label, patch versus no patch).
Importance: Environments associated with smoking increase a smoker's craving to smoke and may provoke lapses during a quit attempt. Identifying smoking risk environments from images of a smoker's daily life provides a basis for environment-based interventions.
Objective: To apply a deep learning approach to the clinically relevant identification of smoking environments among settings that smokers encounter in daily life.
Cue-induced craving among smokers is a well-documented phenomenon. Conditioning theory is used to explain how stimuli elicit cravings. Attachment theory may explain additional influences on cue-induced craving.

Exercise is presumed to be a potentially helpful smoking cessation adjunct reputed to attenuate the negative effects of deprivation. The present study examined the effectiveness of moderate within-session exercise to reduce 4 key symptoms of smoking deprivation during 3 72-hr nicotine abstinence blocks in both male and female smokers. Forty-nine (25 male, 24 female) sedentary smokers abstained from smoking for 3 consecutive days on 3 separate occasions.

Here we examined the effects of exposure to visual smoking environment cues on smoking urge and the ability to resist smoking, as measured with a delay-to-smoking task in which monetary contingencies are provided for resisting smoking.
Methods: Adult daily smokers (n=22) completed two experimental sessions, each following 6h smoking abstinence.
Environments associated with prior drug use provoke craving and drug taking, and set the stage for lapse/relapse. Although the neurobehavioral bases of environment-induced drug taking have been investigated with animal models, the influence of drug-environments on brain function and behavior in clinical populations of substance users is largely unexplored. Adult smokers (n=40) photographed locations personally associated with smoking (personal smoking environments; PSEs) or personal nonsmoking environment (PNEs).

Smoking cue-reactivity studies have consistently demonstrated heightened self-report craving, as well as moderate autonomic reactivity, among smokers exposed to salient drug-related cues. However, significantly fewer studies have examined whether exposure to smoking cues affects smokers' actual smoking, or examined the predictive relationship between cue-induced craving and smoking behavior. Using our well-tested pictorial cues in a cue-reactivity paradigm, we investigated the impact of smoking-related cues relative to neutral cues on subjective craving and smoking behavior (assessed via CReSS; Plowshare Technologies, Baltimore, MD) measures of latency to smoke, puff volume, and number of puffs).

The association between smokers' cue-induced craving and subsequent ability to initiate abstinence is unclear. Dependent smokers (N = 158) completed a single cue-reactivity session prior to participating in a larger within-subjects study, which independently examined predictors of initiating quitting during 5 days each on nicotine versus placebo patch. In the larger study, all smokers used nicotine and placebo patch (double blind) for 1 week each following a preceding week of ad lib smoking, in a 2 × 2 cross-over design.

View Article and Find Full Text PDFIntroduction: Negative mood situations often increase smoking behavior and reward, effects that may be greater among women and smokers low in tolerance for distress.
Methods: Adult dependent smokers (N = 164; 86 men, 78 women) first completed measures of distress tolerance via self-report and by mirror-tracing and breath-holding tasks. They then participated in 2 virtually identical laboratory sessions, involving induction of negative versus neutral mood (control) via pictorial slides and music.
Smoking behavior may be more persistent among those who expect that smoking will relieve negative affect (NA). Assessing smoking expectancies temporally close to mood situations could enhance the predictive value of that assessment. Dependent smokers (n = 71; 43 male, 28 female) participated in five laboratory sessions, each involving mood induction.

However, in line with behavioral theory, recent clinical research suggests self-efficacy ratings may reflect, rather than cause, behavior change. To test these two disparate views, self-efficacy was related to actual smoking abstinence on the next day (i.

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.
Background: Smoking acutely relieves negative affect (NA) due to smoking abstinence but may not relieve NA from other sources, such as stressors.
Methods: Dependent smokers (n = 104) randomly assigned to one of three smoking conditions (nicotine or denicotinized cigarettes, or no smoking) completed four negative mood induction procedures (one per session): 1) overnight smoking abstinence, 2) challenging computer task, 3) public speech preparation, and 4) watching negative mood slides. A fifth session involved a neutral mood control.
Introduction: We recently showed effects of nicotine dose and nicotine expectancy on some responses to cigarette smoking, with generally no influence of induced mood on these effects. The present study extended this line of research to Nicotrol nasal spray, to determine whether formulation (spray vs. smoking) alters responses.

We explored associations of gene variants in the dopamine, opioid, and serotonin pathways with smoking reward ('liking') and reinforcement (latency to first puff and total puffs) as a function of negative mood and expected versus actual nicotine content of the cigarette. Smokers of European ancestry (n=72) were randomized to one of four groups in a 2x2 balanced placebo design, corresponding with manipulation of actual (0.
