Craving to smoke is often conceptualized and measured as a tonic, slowly changing state induced by abstinence. In this article, we review the literature on the existence, causes, and treatment of cue-induced cravings: intense, episodic cravings typically provoked by situational cues associated with drug use. In laboratory research, smokers exposed to(More)
INTRODUCTION The aim of the present study was to explore the viability of using social media as a recruitment tool in a clinical research trial. Sociodemographic data and smoking characteristics were assessed in 266 participants recruited to investigate the effectiveness of a behavioral support program for smoking cessation. METHODS For analysis,(More)
Smoking lapses represent an important juncture between smoking cessation and relapse. Nicotine replacement therapy (NRT) has been shown to decrease the risk of progression from lapse to relapse. We hypothesized that this effect might be mediated via decreases in reinforcement from smoking lapses. We assessed 169 subjects who lapsed during treatment in a(More)
INTRODUCTION Traditionally, smokers have been encouraged to prepare for cessation in advance of a preset quit date, with the expectation that preparation would improve their chance of success. However, a recent survey of U.K. smokers found that a substantial proportion of attempts involved no preplanning and that these spontaneous attempts were actually(More)
OBJECTIVE Nicotine patch improves treatment outcomes, but lapses are still common. To understand the process of relapse on patch, we investigated differences in the antecedents (withdrawal, setting, triggers) of lapse episodes experienced on high-dose (35 mg) nicotine patches versus placebo. DESIGN Participants were smokers who lapsed during a randomized,(More)
Intermittent smokers (ITS) - who smoke less than daily - comprise an increasing proportion of adult smokers. Their smoking patterns challenge theoretical models of smoking motivation, which emphasize regular and frequent smoking to maintain nicotine levels and avoid withdrawal, but yet have gone largely unexamined. We characterized smoking patterns among(More)
Several pharmacotherapies for tobacco dependence and withdrawal have been approved by the Food and Drug Administration to aid smoking cessation. These medicines double to triple the odds of cessation compared to placebo, with the diversity in chemical entity (e.g., nicotine, varenicline, bupropion) and route (e.g., nicotine gum and transdermal patch)(More)
INTRODUCTION AND AIMS Antecedents of smoking have been widely researched in studies with older adults. However, less is known about the smoking patterns and antecedents of smoking in young adult smokers. DESIGN AND METHODS In this study, we used ecological momentary assessment collected with an Internet-based survey instrument and used the participants'(More)
BACKGROUND Many smokers express a desire to quit smoking by gradually reducing the number of cigarettes they smoke until they stop completely. This study tested the efficacy of nicotine gum in facilitating cessation through gradual reduction. DESIGN This was a multi-center, placebo-controlled, double-blind RCT of 2- and 4-mg nicotine gum versus placebo.(More)
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(More)
