Experimental and occasional cigarette use among college students is widespread. Little is known about what differentiates the occasional college smoker who becomes a regular smoker from the one who does not. Possible risk factors include peer smoking, lifestyle factors, such as lack of exercise, and health/addiction concerns. The current study investigated the progression of smoking in a cohort of 321 low-level/occasional smokers. Over the course of 4 years, 45% of low-level/occasional users had become nonsmokers, 35% became occasional smokers, and 20% became daily smokers. Baseline exercise patterns, addiction beliefs, and smoking pervasiveness were modestly related to distal smoking outcome. The level of baseline smoking was strongly related to smoking outcome. These results support the wisdom of limiting access and exposure to cigarettes among the college population. [Copyright &y& Elsevier]

The current study examined the relation between drinking and smoking abstinence in a community-based sample from the Working Well Trial (WWT). At baseline, drinking level was related to smoking history (never, former, or current smoker; P<.0001) and abstinence history. Mean monthly alcohol consumption increased linearly with decreases in duration of recent abstinence (i.e., longest period quit in the past year among current smokers; P<.05) and current abstinence (i.e., time since quitting among former smokers; P<.0001), even controlling for relevant demographic factors. Among baseline smokers, lower beer consumption predicted smoking abstinence at 4-year follow-up (P<.01). A trend towards significance was found for total alcohol consumption (P=.06). The results suggest (a) a dose–response relation between baseline drinking and duration of smoking abstinence, and (b) that heavier drinkers are less likely to quit smoking over a 4-year period.

Ambulatory assessment of smoking behavior has greatly advanced our knowledge of the smoking cessation process. The current article first provides a brief overview of ecological momentary assessment for smoking cessation and highlights some of the primary advantages and scientific advancements made from this data collection method. Next, a discussion of how certain data collection tools (i.e., smoking topography and carbon monoxide detection) that have been traditionally used in lab-based settings are now being used to collect data in the real world. The second half of the paper focuses on the use of wearable wireless sensors to collect data during the smoking cessation process. Details regarding how these sensor-based technologies work, their application to newer tobacco products, and their potential to be used as intervention tools are discussed. Specific focus is placed on the opportunity to utilize novel intervention approaches, such as Just-In-Time Adaptive Interventions, to intervene upon smoking behavior. Finally, a discussion of some of the current challenges and limitations related to using sensor-based tools for smoking cessation are presented, along with suggestions for future research in this area.

Background: Smartphone apps can provide real-time, tailored interventions for smoking cessation. The current study examines the effectiveness of a smartphone-based smoking cessation application that assessed risk for imminent smoking lapse multiple times per day and provided messages tailored to current smoking lapse risk and specific lapse triggers.Methods: Participants (N=59) recruited from a safety-net hospital smoking cessation clinic completed phone-based ecological momentary assessments (EMAs) 5 times/day for 3 consecutive weeks (1week pre-quit, 2weeks post-quit). Risk for smoking lapse was estimated in real-time using a novel weighted lapse risk estimator. With each EMA, participants received messages tailored to current level of risk for imminent smoking lapse and self-reported presence of smoking urge, stress, cigarette availability, and motivation to quit. Generalized linear mixed model analyses determined whether messages tailored to specific lapse risk factors were associated with greater reductions in these triggers than messages not tailored to specific triggers.Results: Overall, messages tailored to smoking urge, cigarette availability, or stress corresponded with greater reductions in those triggers than messages that were not tailored to specific triggers (p's=0.02 to <0.001). Although messages tailored to stress were associated with greater reductions in stress than messages not tailored to stress, the association was non-significant (p=0.892) when only moments of high stress were included in the analysis.Conclusions: Mobile technology can be used to conduct real-time smoking lapse risk assessment and provide tailored treatment content. Findings provide initial evidence that tailored content may impact users' urge to smoke, stress, and cigarette availability. [ABSTRACT FROM AUTHOR]- Published

Tobacco and alcohol use are linked behaviors that individually and synergistically increase the risk for negative health consequences. This study was a two-group, randomized clinical trial evaluating the efficacy of a behavioral intervention, "Motivation And Problem Solving Plus" (MAPS+), designed to concurrently address smoking cessation and the reduction of at-risk drinking. Targeted interventions may promote coaction, the likelihood that changing one behavior (smoking) increases the probability of changing another behavior (alcohol use). Puerto Ricans (N=202) who were smokers and at-risk drinkers were randomized to standard MAPS treatment focused exclusively on smoking cessation (S-MAPS), or MAPS+, focused on cessation and at-risk drinking reduction. Drinking outcomes included: number of at-risk drinking behaviors, heavy drinking, binge drinking, and drinking and driving. MAPS+ did not have a significant main effect on reducing at-risk drinking relative to S-MAPS. Among individuals who quit smoking, MAPS+ reduced the number of drinking behaviors, the likelihood of meeting criteria for heavy drinking relative to S-MAPS, and appeared promising for reducing binge drinking. MAPS+ did not improve drinking outcomes among individuals who were unsuccessful at quitting smoking. MAPS+ showed promise in reducing at-risk drinking among Puerto Rican smokers who successfully quit smoking, consistent with treatment enhanced coaction. Integrating an alcohol intervention into cessation treatment did not reduce engagement in treatment, or hinder cessation outcomes, and positively impacted at-risk drinking among individuals who quit smoking. Findings of coaction between smoking and drinking speak to the promise of multiple health behavior change interventions for substance use treatment and chronic disease prevention.

Smoking cessation treatments that are easily accessible and deliver intervention content at vulnerable moments (e.g., high negative affect) have great potential to impact tobacco abstinence. The current study examined the feasibility and acceptability of a multi-component Just-In-Time Adaptive Intervention (JITAI) for smoking cessation. Daily smokers interested in quitting were consented to participate in a 6-week cessation study. Visit 1 occurred 4 days pre-quit, Visit 2 was on the quit day, Visit 3 occurred 3 days post-quit, Visit 4 was 10 days post-quit, and Visit 5 was 28 days post-quit. During the first 2 weeks (Visits 1-4), the JITAI delivered brief mindfulness/motivational strategies via smartphone in real-time based on negative affect or smoking behavior detected by wearable sensors. Participants also attended 5 in-person visits, where brief cessation counseling (Visits 1-4) and nicotine replacement therapy (Visits 2-5) were provided. Outcomes were feasibility and acceptability; biochemically-confirmed abstinence was also measured. Participants (N = 43) were 58.1 % female (AgeMean = 49.1, mean cigarettes per day = 15.4). Retention through follow-up was high (83.7 %). For participants with available data (n = 38), 24 (63 %) met the benchmark for sensor wearing, among whom 16 (67 %) completed at least 60 % of strategies. Perceived ease of wearing sensors (Mean = 5.1 out of 6) and treatment satisfaction (Mean = 3.6 out of 4) were high. Biochemically-confirmed abstinence was 34 % at Visit 4 and 21 % at Visit 5. Overall, the feasibility of this novel multi-component intervention for smoking cessation was mixed but acceptability was high. Future studies with improved technology will decrease participant burden and better detect key intervention moments. [ABSTRACT FROM AUTHOR]

Although over 70% of homeless individuals smoke, few studies have examined the effectiveness of smoking cessation interventions in this vulnerable population. The purpose of this pilot study was to compare the effectiveness of shelter-based smoking cessation clinic usual care (UC) to an adjunctive contingency management (CM) treatment that offered UC plus small financial incentives for smoking abstinence. Sixty-eight homeless individuals in Dallas, Texas (recruited in 2012) were assigned to UC (n =58) or UC plus financial incentives (CM; n =10) groups and were followed for 5 consecutive weeks (1 week pre-quit through 4 weeks post-quit). A generalized linear mixed model regression analysis was conducted to compare biochemically-verified abstinence rates between groups. An additional model examined the interaction between time and treatment group. The participants were primarily male (61.8%) and African American (58.8%), and were 49 years of age on average. There was a significant effect of treatment group on abstinence overall, and effects varied over time. Follow-up logistic regression analyses indicated that CM participants were significantly more likely than UC participants to be abstinent on the quit date (50% vs. 19% abstinent) and at 4 weeks post-quit (30% vs. 1.7% abstinent). Offering small financial incentives for smoking abstinence may be an effective way to facilitate smoking cessation in homeless individuals. [Copyright &y& Elsevier]

Abstract: The current study utilized regression analyses to explore the relationships among demographic and linguistic indicators of acculturation, gender, and tobacco dependence among Spanish-speaking Latino smokers in treatment. Additionally, bootstrapping analyses were used to examine the role of dependence as a mediator of the relationship between indicators of acculturation and cessation. Indicators of time spent in the United States were related to indicators of physical dependence. Preferred media language was related to a multidimensional measure of dependence. Gender did not impact the relationships between acculturation indicators and dependence. A multidimensional measure of dependence significantly mediated the relationship between preferred media language and cessation. Future research would benefit from consideration of acculturation and multidimensional measures of dependence when studying smoking cessation among Latinos, and from further examination of factors accounting for relationships among acculturation, dependence, and cessation.

Abstract: In this study, we examined the relationship between the level of daily cigarette consumption and the startle response to affective and cigarette-related cues among treatment-seeking smokers. Before receiving any behavioral or pharmacological treatment, 136 smokers attended a baseline laboratory session, during which we recorded their reflexive eyeblink responses to acoustic startle probes while they were viewing pleasant, unpleasant, neutral, and cigarette-related pictures. We found that 1) cigarette-related and pleasant pictures similarly reduced the startle magnitude compared to neutral pictures; 2) the magnitude of startle modulation rendered by pleasant or unpleasant pictures did not differ among light, moderate, and heavy smokers; and 3) startle attenuation by cigarette-related pictures was greater in heavy smokers than in light smokers. These results suggest that similar to pleasant stimuli, cigarette-related cues are motivationally salient for smokers, and that this salience increases with nicotine dependence.

Abstract: The majority of smoking cessation research has focused on heavy smokers. African Americans (AA) are less likely than the general population to be heavy smokers. Thus, little is known about the smoking and psychosocial characteristics of lighter AA smokers. The present study compared the baseline demographic, smoking, and psychosocial characteristics of light (5–10 cigarettes per day; n =86) and moderate to heavy (>10 cigarettes per day; n =286) AA smokers enrolled in a smoking cessation clinical trial. Results indicated no differences between groups on demographic variables. However, light smokers (LS) were less dependent on smoking, reported more previous quit attempts, and had higher self-efficacy to quit than moderate to heavy smokers (MHS). On a measure of withdrawal, LS reported less pre-quit craving and less difficulty concentrating than MHS. In addition, LS reported lower perceived stress, fewer symptoms of depression, and greater positive affect than AA MHS. These findings highlight important similarities and differences between AA LS and MHS, and have implications for the treatment of AA smokers. [Copyright &y& Elsevier]

Abstract: Research suggests that there are racial disparities in smoking behaviors, cessation rates, mortality, and morbidity. However, little is known regarding racial differences in affect regulation by smoking. The purpose of this study was to examine racial differences in the effects of nicotine deprivation and administration on smokers'' startle responding to smoking and affective cues. 104 African American (AA) and Caucasian American (CA) smokers completed 4 laboratory sessions crossing nicotine deprivation (12-hour deprived vs. nondeprived) with nicotine nasal spray (active vs. placebo). Participants viewed affective (positive, neutral, and negative) and smoking slides while startle probes were administered. The results showed that relative to placebo, AA smokers given nicotine spray exhibited significantly lower startle responses when they were exposed to smoking cues and CA smokers given nicotine spray exhibited significantly lower startle responses when they were exposed to negative and neutral cues. Although nicotine suppresses startle responding in both AA and CA smokers, the effect is modulated by different cue conditions, suggesting that there may be racial differences in components of smoking motivation.

Abstract: Men and women may differ in their sensitivity to the mood-modulating properties of nicotine. Male and female adult smokers were exposed to four sessions crossing two nicotine deprivation conditions (12-h deprived vs. nondeprived) with two drug conditions (nicotine vs. placebo nasal spray). Acoustic probes elicited startle eyeblink responses while viewing affective and cigarette-related slides. In-session mood ratings were collected to gauge self-reported negative affect, positive affect, and craving. Nicotine nasal spray reduced startle amplitude in both men and women following 12-h deprivation compared with smoking nondeprivation. During nondeprivation, nicotine nasal spray increased startle amplitude in women compared with placebo spray, whereas no difference was found for men. The startle results suggest that both men and women are responsive to the hedonic properties of nicotine. [Copyright &y& Elsevier]
