Background: The combined use of cigarettes and alcohol is associated with a synergistic increase in the risk of morbidity and mortality. Continued alcohol use during a smoking quit attempt is a considerable risk factor for smoking relapse. As such, there is a need for interventions that address both behaviors concurrently. Mindfulness-based interv...

Objectives The mindful smoking exercise instructs participants to pay attention to a range of experiences while smoking a cigarette with the expectation that it will modify the often automatic process of smoking. Given its theoretical value, mindfulness- and acceptance and commitment therapy–based smoking cessation interventions have usually includ...

In the midst of the COVID-19 pandemic, many research and clinical teams have transitioned their projects to a remote-based format, weighing the pros and cons of making such a potentially disruptive decision. One key aspect of this decision is related to the patient population, with underserved populations possibly benefiting from the increased reac...

Most users of electronic cigarettes (e-cigarettes) report initiating use to quit combustible cigarettes. Nevertheless, high levels of dual use (i.e., using both combustible cigarettes and e-cigarettes) occur among adults. Using formative data from in-depth interviews and employing learner verification, we adapted an existing, validated self-help sm...

The combined use of cigarettes and alcohol is associated with an increased risk of morbidity and mortality. Yet, efficacious interventions that address both behaviors concurrently are lacking. Smoking cessation and alcohol modification not only garner health benefits, but there is also value in addressing alcohol use in the context of smoking cessa...

Objective: The exclusion criteria of tobacco cessation randomized clinical trials (RCTs) may have unintended consequences on inclusion and cessation disparities. We examined racial/ethnic differences in: a) ex­clusion from a group-based cessation RCT; and b) reasons for exclusion. Design: Quasi-experimental. Inclusion criteria were self-identifica...

There is a need for effective smoking cessation interventions that can be disseminated easily in health care and other settings. We previously reported that an extended self-help intervention comprising intensive repeated mailings over 18 months improved abstinence rates through 6 months beyond the end of the intervention when compared to both a re...

Racial/ethnic disparities in tobacco cessation are such that U.S. minorities have greater difficulty quitting compared to White non-Hispanics. Group differences in distress (i.e., perceived stress and depressive symptoms) may contribute to cessation disparities. The allostasis model of health suggests that the toll of chronic stress experienced by...

Smoking-related illnesses are the leading causes of death among Hispanics/Latinos. Yet, there are few smoking cessation interventions targeted for this population. The goal of this study was to “transcreate” an existing, previously validated, English language self-help smoking cessation intervention, titled Forever Free®: Stop Smoking for Good, for...

Background The use of electronic cigarettes (e-cigarettes) has increased dramatically over the past decade. Although the majority of users report initiating e-cigarette use (vaping) to quit or reduce use of combustible cigarettes (smoking), a substantial proportion become “dual users” of both. Little is known about the patterns of dual use of, and...

Introduction: Varenicline reduces smoking satisfaction during the pre-cessation run-in period, which may contribute to extinction of cravings and smoking behavior. Research indicates that efficacy is enhanced when the run-in period is increased from 1 to 4 weeks, providing a longer extinction opportunity. We hypothesized that efficacy could be fur...

Electronic Nicotine Delivery Systems, also called electronic cigarettes or e-cigarettes, have been available for over a decade and use has been increasing dramatically. The primary reported reasons for use are to aid smoking cessation or reduction, yet a significant proportion appear to be long-term users of both products (“dual users”). Dual users...

The underrepresentation of racial/ethnic minorities in smoking cessation trials may contribute to disparities in quitting. The strict inclusion and exclusion criteria of randomized controlled trials (RCTs) may have unintended consequences on racial/ethnic inclusivity. The present study examined racial/ethnic differences in (a) exclusion from a grou...

Multiple recruitment strategies are often required to obtain a diverse sample of treatment-seeking smokers. This study is a multisite, behavioral randomized controlled trial designed to address racial/ethnic cessation disparities, among non–Hispanic White, African American, and Hispanic smokers. We implemented an 18-month recruitment campaign utili...

There is a dearth of evidence-based smoking-cessation interventions for Hispanic/Latino smokers, especially for individuals with limited or no English proficiency. Hispanics/Latinos make up 17% of the national population, and in some Hispanic sub-ethnic groups, such as Puerto Ricans and Cubans, smoking prevalence rates are over 30% (greatly exceedi...

Background: There has been an exponential increase in the prevalence of e-cigarette use, particularly among youth. However, adult use is also rising, and there have been relatively few qualitative studies with adult users to understand their reasons for use and future use intentions. Such information is needed to inform both prevention and cessati...

Introduction Far too few smokers receive recommended interventions at their healthcare visits, highlighting the importance of identifying effective, low-cost smoking interventions that can be readily delivered. Self-help interventions (e.g., written materials) would meet this need, but they have shown low efficacy. The purpose of this RCT was to de...

Introduction: Given the rapid increase in e-cigarette use, it is important to understand factors that may contribute to their initiation and maintenance. Because gender differences in tobacco use, product preferences, and expectancies are well established, similar gender differences may exist with e-cigarettes. The aim of this study was to identif...

Many smokers who have tried electronic cigarettes ("e-cigarettes") continue to smoke, perhaps influenced by their beliefs about the outcomes of using e-cigarettes ("e-cigarette expectancies"). The primary aims of this study were to compare expectancies of dual users to former smokers, and to examine the association between expectancies and intentio...

Relapse prevention (RP) remains a major challenge to smoking cessation. Previous research found that a set of self-help RP booklets significantly reduced smoking relapse. This study tested the effectiveness of RP booklets when added to the existing services of a telephone quitline. Quitline callers (N = 3458) were enrolled after their 2-week quitli...

Introduction: Use of e-cigarettes has been increasing exponentially, with the primary motivation reported as smoking cessation. To understand why smokers choose e-cigarettes as an alternative to cigarettes, as well as to US Food and Drug Administration (FDA)--approved nicotine replacement therapies (NRT), we compared outcome expectancies (beliefs...

Tobacco smoking is the leading preventable cause of mortality and morbidity. Although behavioral counseling combined with pharmacotherapy is the most effective approach to aiding smoking cessation, intensive treatments are rarely chosen by smokers, citing inconvenience. In contrast, minimal self-help interventions have the potential for greater rea...

The primary aim of this study was to assess smoking characteristics and cessation motivation prior to and after initiation of multidisciplinary chronic pain treatment. A secondary aim was to identify predictors of cessation motivation among smokers initiating treatment for chronic pain. We used a prospective, nonrandomized, repeated measures design...

Expectancies regarding treatment assignment may influence outcomes in placebo-controlled trials above and beyond actual treatment assignment. For smoking pharmacotherapies, guessing enrollment in the active medication treatment is associated with higher abstinence rates. However, placebo-controlled trials of smoking pharmacotherapies rarely assess...

Based on the principles of Pavlovian learning and extinction, cue exposure therapy (CET) involves repeated exposure to substance-associated cues to extinguish conditioned cravings and reduce the likelihood of relapse. The efficacy of CET is predicated on successful extinction, yet the process of extinction in CET trials has rarely been demonstrated...

Policies restricting indoor worksite tobacco use began being implemented more than a decade ago. More recently, the scope of these policies has been expanding to outdoors, with hospitals leading the trend in restricting smoking throughout their grounds. However, research on the effects such bans have on employees is scarce. The purpose of the curre...

Health care providers (HCPs) can play an important role in promoting smoking cessation and preventing relapse. Public Health Service guidelines recommend the "5A's" model of brief intervention. The goal of the current study was to examine cancer patients' perceptions of 5A's model implementation by their oncology HCPs. This study included 81 thorac...

Varenicline is an α4β2 nicotinic acetylcholine receptor partial agonist that has been found to be effective for treating tobacco dependence. However, the subjective and behavioral mediators of its efficacy are not known. Using multiple sessions of laboratory-based assessment, this double-blind, placebo-controlled experiment was designed to test if...

Tobacco use is responsible for at least 30% of all cancer deaths; smoking cessation is associated with decreased mortality and morbidity. This chapter reviews the evidence-based treatments for tobacco use and dependence, drawing primarily from the US Public Health Service’s Clinical Practice Guidelines. The treatments reviewed include pharmacothera...

This study evaluated additive and interactive models of the effects of acute stressful life events, chronic life stressors, and immediate substance availability on substance use following alcohol and drug treatment. One hundred and two veterans meeting DSM-IV criteria for alcohol, cannabis, or stimulant dependence at treatment entry completed quart...

To evaluate the incremental effectiveness and cost-effectiveness of a staged-based, computerized smoking cessation intervention relative to standard care in an urban managed care network of primary care physicians. Decision-analytic model based on results of a randomized clinical trial. Patient outcomes and cost estimates were derived from clinical...

The primary care visit represents an important venue for intervening with a large population of smokers. However, physician adherence to the Smoking Cessation Clinical Guideline (5As) remains low. We evaluated the effectiveness of a computer-tailored intervention designed to increase smoking cessation counseling by primary care physicians. Physicia...

This study examined the context of initial posttreatment substance use episodes and 1-year treatment outcomes among substance abusers in relation to Axis I psychiatric diagnoses. Of the 210 adults meeting DSM-III-R diagnostic criteria for a substance use disorder (SUD), 102 also met criteria for mood disorder, posttraumatic stress disorder (PTSD),...

Little is known about the natural course of smoking behaviors following substance use treatment, particularly among individuals with comorbid substance use and psychiatric disorders. This study examined smoking cessation efforts among 120 substance abusers with and without psychiatric comorbidity. Participants completed assessments of smoking prior...

Whereas research on the antinociceptive effects of cigarette smoking has produced inconsistent findings, certain aspects of attentional processing repeatedly have been found to have an impact on pain perception. In an effort to delineate the relation between smoking and pain, the present study tested the attentional mediation model of smoking in pa...

Motivational models of alcohol use often invoke constructs derived from social-learning theory, including coping styles, drinking motives and affective distress. To date, no study has assessed the potential role of negative mood regulation (NMR) expectancies (the extent to which one holds positive expectations of one's ability to cope with negative...

Based on J.D. Kassel and S. Shiffman's (1997) study, the hypothesis was tested that cigarette smoking's anxiolytic effects are attentionally mediated and depend on the presence of benign distraction. This study explored whether the attentionally mediated anxiolytic effects of smoking observed in the J. D. Kassel and S. Shiffman (1997) study could b...
