Abstract
OBJECTIVE The present research sought to examine whether cohabitation with a smoker undermines smoking cessation among people engaged in a cessation programme and whether the components of the Theory of Planned Behaviour (TPB) act as mediating mechanisms. DESIGN A prospective longitudinal study with online questionnaires was conducted among smokers living in Switzerland who enrolled in a 6-months smoking cessation programme. MAIN OUTCOME MEASURES Cohabitation with a smoker and the TPB constructs were assessed 10 days after the start of the programme (T1; N = 820). Smoking abstinence was measured at T1, and at 3-months (T2; N = 624) and 6-months follow-ups (T3; N = 354). RESULTS Results showed that living with a smoker decreased the odds that smokers remained abstinent throughout the cessation programme. Furthermore, we found that cohabitation was negatively associated with subjective norm. Afterwards, subjective norm predicted intention to maintain smoking cessation, which, in turn, predicted smoking abstinence. Such mediation effects persisted at each time point. CONCLUSION The present research provided evidence that living with other smokers at home can lead to greater risks of relapsing among people engaged in a cessation programme. We discussed the role of smoking-related norms in the efficacy of cessation interventions. Supplemental data for this article is available online at https://doi.org/10.1080/08870446.2022.2041638 .

Changes in smoking status among a longitudinal cohort of gay, bisexual, and other men who have sex with men in Vancouver, Canada. Drug Alcohol Depend 2017; 179:370-378. [PMID: 28844014 PMCID: PMC5832025 DOI: 10.1016/j.drugalcdep.2017.07.025] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2017] [Revised: 07/24/2017] [Accepted: 07/25/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Cigarette smoking is common among gay, bisexual, and other men who have sex with men (GBMSM) and most of the mortality gap between HIV-positive and HIV-negative individuals is attributable to smoking. METHODS We recruited sexually active HIV-positive and HIV-negative GBMSM age ≥16 years using respondent-driven sampling. Study visits occurred every six months for up to four years and included a computer-assisted self-interview and clinical assessment. We conducted bivariate analyses to compare factors associated with "never", "former", "daily", or "non-daily" smoking at baseline and longitudinal mixed effects models to examine factors associated with cessation and (re)initiation. RESULTS 774 participants completed a baseline visit and 525 enrolled in the cohort and completed at least one follow-up visit. At baseline, the median age was 34 years and 31.5% were daily smokers. In follow-up (median=2.5years), 116 daily or non-daily smokers (41%) quit at least once and of these, 101 (87%) remained former smokers at their last visit. Smoking cessation was positively associated with incomes ≥$60,000 and self-reported excellent health. Alcohol use, ecstasy use, and having a partner who smokes were associated with decreased odds of cessation. Substance use (cannabis, GHB, and crystal methamphetamine) and having a partner who smokes were positively associated with increasing to/resuming daily smoking. HIV-positive GBMSM were more likely to smoke but not more likely to quit. CONCLUSIONS Targeted, culturally relevant smoking cessation resources are needed, especially for HIV-positive GBMSM. Engaging couples in cessation interventions may be useful.

Abstract
Compulsive smoking is a worldwide public health problem. Although research has confirmed the importance of associative learning processes in nicotine addiction, therapies targeting nicotine-associated cues still have a high relapse rate. Most theories conceptualize nicotine as an ‘outcome’ that reinforces behaviors and/or changes the affective value of stimuli. Albeit important, this view does not capture the complexity of associative processes involved in nicotine addiction. For example, nicotine serves as a conditional stimulus acquiring new appetitive/affective properties when paired with a non-drug reward. Also, nicotine functions as an occasion setter that participates in higher-order associative processes that likely permit a more pervasive influence of conditioned cues that are resistant to typically cue-exposure therapy techniques. Finally, nicotine appears to amplify the salience of other stimuli that have some incentive value resulting in enhanced nicotine selfadministration and conditioned reinforcement processes. Future smoking intervention strategies should take into consideration these additional associative learning processes.

Abstract
BACKGROUND Many smokers give up smoking on their own, but materials giving advice and information may help them and increase the number who quit successfully. OBJECTIVES The aims of this review were to determine: the effectiveness of different forms of print-based self-help materials, compared with no treatment and with other minimal contact strategies; the effectiveness of adjuncts to print-based self help, such as computer-generated feedback, telephone hotlines and pharmacotherapy; and the effectiveness of approaches tailored to the individual compared with non-tailored materials. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group trials register. Date of the most recent search April 2014. SELECTION CRITERIA We included randomized trials of smoking cessation with follow-up of at least six months, where at least one arm tested a print-based self-help intervention. We defined self help as structured programming for smokers trying to quit without intensive contact with a therapist. DATA COLLECTION AND ANALYSIS We extracted data in duplicate on the participants, the nature of the self-help materials, the amount of face-to-face contact given to intervention and to control conditions, outcome measures, method of randomization, and completeness of follow-up.The main outcome measure was abstinence from smoking after at least six months follow-up in people smoking at baseline. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates when available. Where appropriate, we performed meta-analysis using a fixed-effect model. MAIN RESULTS We identified 74 trials which met the inclusion criteria. Many study reports did not include sufficient detail to judge risk of bias for some domains. Twenty-eight studies (38%) were judged at high risk of bias for one or more domains but the overall risk of bias across all included studies was judged to be moderate, and unlikely to alter the conclusions.Thirty-four trials evaluated the effect of standard, non-tailored self-help materials. Pooling 11 of these trials in which there was no face-to-face contact and provision of structured self-help materials was compared to no intervention gave an estimate of benefit that just reached statistical significance (n = 13,241, risk ratio [RR] 1.19, 95% confidence interval [CI] 1.04 to 1.37). This analysis excluded two trials with strongly positive outcomes that introduced significant heterogeneity. Six further trials without face-to-face contact in which the control group received alternative written materials did not show evidence for an effect of the smoking self-help materials (n = 7023, RR 0.88, 95% CI 0.74 to 1.04). When these two subgroups were pooled, there was no longer evidence for a benefit of standard structured materials (n = 20,264, RR 1.06, 95% CI 0.95 to 1.18). We failed to find evidence of benefit from providing standard self-help materials when there was brief contact with all participants (5 trials, n = 3866, RR 1.17, 95% CI 0.96 to 1.42), or face-to-face advice for all participants (11 trials, n = 5365, RR 0.97, 95% CI 0.80 to 1.18).Thirty-one trials offered materials tailored for the characteristics of individual smokers, with controls receiving either no materials, or stage matched or non-tailored materials. Most of the trials used more than one mailing. Pooling these showed a benefit of tailored materials (n = 40,890, RR 1.28, 95% CI 1.18 to 1.37) with moderate heterogeneity (I² = 32%). The evidence is strongest for the subgroup of nine trials in which tailored materials were compared to no intervention (n = 13,437, RR 1.35, 95% CI 1.19 to 1.53), but also supports tailored materials as more helpful than standard materials. Part of this effect could be due to the additional contact or assessment required to obtain individual data, since the subgroup of 10 trials where the number of contacts was matched did not detect an effect (n = 11,024, RR 1.06, 95% CI 0.94 to 1.20). In two trials including a direct comparison between tailored materials and brief advice from a health care provider, there was no evidence of a difference, but confidence intervals were wide (n = 2992, RR 1.13, 95% CI 0.86 to 1.49).Only four studies evaluated self-help materials as an adjunct to nicotine replacement therapy, with no evidence of additional benefit (n = 2291, RR 1.05, 95% CI 0.88 to 1.25). A small number of other trials failed to detect benefits from using additional materials or targeted materials, or to find differences between different self-help programmes. AUTHORS' CONCLUSIONS Standard, print-based self-help materials increase quit rates compared to no intervention, but the effect is likely to be small. We did not find evidence that they have an additional benefit when used alongside other interventions such as advice from a healthcare professional, or nicotine replacement therapy. There is evidence that materials that are tailored for individual smokers are more effective than non-tailored materials, although the absolute size of effect is still small. Available evidence tested self-help interventions in high income countries; further research is needed to investigate their effect in contexts where more intensive support is not available.

Abstract
Economic evaluations are an important tool to improve our understanding of the costs and effects of health care services and to create sustainable health care systems. This article critically assesses empirical evidence from economic evaluations of pharmaco- and behavioral therapies for smoking cessation. A comprehensive literature review of PubMed and the British National Health Service Economic Evaluation Database was conducted. The search identified 15 articles on nicotine-based pharmacotherapies, 12 articles on nonnicotine based pharmacotherapies, no articles on selegiline, and 10 articles on brief counseling for smoking cessation treatment. Results show that both pharmaco- and behavioral therapies for smoking cessation are cost-effective or even cost-saving. The review highlights several shortcomings in methodology and a lack of standardization of current economic evaluations. Efforts to improve methodology will help make future studies more comparable and increase the evidence base so that such evaluations can be more useful to public health practitioners and policy makers.

Abstract
The model of fantasy realisation (Oettingen, 2000) specifies mental contrasting of a positive future with negative reality as a strategy that creates strong goal commitments. We propose that fantasies about a positive and negative future produce strong goal commitments when contrasted with the respective reality. The present study supports this hypothesis in the area of reducing cigarette consumption. Mental contrasting of a positive future with negative reality as well as mental contrasting of a negative future with positive reality led to taking immediate action when participants had high expectations of success. Results indicate that both fantasies about a positive future and a negative future can be used to commit to goals that benefit health and prevent disease.

Abstract
Most longitudinal, correlational studies on health-behaviour change examine effects of Time1 social-cognitive predictors on subsequent behaviour. In contrast, our research focuses on associations between changes in predictors with change in behaviour. The Health Action Process Approach (HAPA) distinguishes between motivational predictors for intention formation and volitional predictors for behavioural change and served as theoretical basis. Two online-studies were launched targeting different behaviours (low-fat diet, smoking), different samples (Study 1: N = 469; Study 2: N = 441) and different time spans (Study 1: 3 months, Study 2: 4 weeks). Data were analysed by means of structural equation modelling with latent difference scores. Both studies resulted in almost parallel prediction patterns. Change in risk awareness and change in outcome expectancies did not result in change in intentions, whereas change in self-efficacy was of crucial importance. Change in behaviour was associated with change in action planning and action control over and above the effects of intentions. In one study, increases in self-efficacy yielded increases in behaviour change. Results demonstrate that change in action planning and especially action control was of great importance for behaviour change across two different behaviours. Analysing change in social-cognitive predictors allows drawing precise conclusions for interventions.

Abstract
A marked shift in tobacco-related workplace health promotion intervention involves the adoption of policies barring employment to smokers. We discuss the potential public health consequences of these policies on those affected-smokers, their families, the surrounding community and society at large. We find a lack of published evidence evaluating the effectiveness and consequences of these policies. By developing a model of policy effects, we outline possible unintended consequences. With such large gaps in the evidence base and the potential for deleterious consequences, we argue for increased discussion about the use of smoker-free employment policies as a public health intervention and for increased engagement of employers by the public health community in worksite health promotion.

Abstract
BACKGROUND Helping young smokers to quit early in life substantially reduces the risk of later morbidity and mortality due to tobacco use. The RealU study demonstrated the efficacy of a smoking-cessation website for college students that incorporated both individually tailored feedback and peer e-mail support. The relationship between peer e-mail support and cessation outcomes among intervention participants is examined here. METHODS This study was conducted at the University of Minnesota Twin Cities from Fall 2004 through Spring 2005. During the intervention period, peer-support students (E-pals) wrote weekly e-mails to intervention group participants (n=257) encouraging healthy behaviors including smoking abstinence. Ten survey items assessed perceived E-pal supportiveness. The number of e-mails replies sent by the participants to their E-pal was tracked as a measure of e-mail engagement. The primary outcome was self-reported 30-day abstinence at the end of the intervention period. RESULTS Over the course of the intervention, participants sent an average of 4.6 (SD=3.6) e-mails to their E-pals. Perceived E-pal support was significantly correlated with e-mail engagement (p<0.001). At Week 30, 40.5% of individuals in the RealU intervention group (104/257) reported not smoking any cigarettes in the prior 30 days. Bivariate analyses indicated that 30-day abstinence was related to both perceived support from the E-pal (p<0.001) and e-mail engagement (p<0.001). Multivariate analyses indicated that after controlling for age and baseline-level smoking, e-mail engagement remained a significant predictor of 30-day abstinence (p<0.001). CONCLUSIONS Greater peer engagement via e-mail was associated with increased smoking abstinence and reduced frequency of smoking. These findings suggest that online peer support may be an important strategy when delivering Internet-assisted cessation programs to young adults.

Abstract
The purpose of the study was to explore whether sociodemographic characteristics and baseline psychosocial factors were related to short-term smoking cessation and reduction, after controlling for the effects of participating in a virtual world, Internet chat room intervention. Results indicate that smoking-related psychosocial factors are important predictors of adolescent smoking cessation and reduction, independent of the effects of participating in the intervention. Self-efficacy for quitting, social support, and perceived benefits of quitting was related to positive short-term changes in smoking behavior.

Abstract
The goal of this longitudinal study was to test an innovative approach to smoking cessation that might be particularly attractive to adolescent smokers. The study was a participatory research effort between academic and school partners. The intervention used an Internet-based, virtual reality world combined with motivational interviewing conducted in real-time by a smoking cessation counselor. Participants were 136 adolescent smokers recruited from high schools randomized to the intervention or a measurement-only control condition. Those who participated in the program were significantly more likely than controls to report at the immediate post-intervention assessment that they had abstained from smoking during the past week (p<or=.01), smoked fewer days in the past week (p<or=.001), smoked fewer cigarettes in the past week (p<or=.01), and considered themselves a former smoke (p<or=.05). Only the number of times quit was statistically significant at a one-year follow-up assessment (p<or=.05). The lack of longer-term results is discussed, as are methodological challenges in conducting a cluster-randomized smoking cessation study.

This analysis excluded two trials with strongly positive outcomes that introduced significant heterogeneity. Four further trials in which the control group received alternative written materials did not show evidence for an effect of the smoking self-help materials. We failed to find evidence of benefit from adding self-help materials to face-to-face advice, or to nicotine replacement therapy. There were seventeen trials using materials tailored for the characteristics of individual smokers, where meta-analysis supported a small benefit of tailored materials (N = 20,414; OR 1.42, 95% CI 1.26 to 1.61). The evidence is strongest for tailored materials compared to no intervention, but also supports tailored materials as more helpful than standard materials. Part of this effect could be due to the additional contact or assessment required to obtain individual data. A small number of other trials failed to detect benefits from using additional materials or targeted materials, or to find differences between different self-help programmes.

Abstract
Effective smoking cessation interventions include steps often protocolised as the 4A method. This study assessed how pulmonologists address the smoking behaviour of chronic obstructive pulmonary disease (COPD) patients and analysed psychosocial differences between pulmonologists who intend to use the 4A method and those who do not intend to use it. A nationwide survey was conducted among Dutch pulmonologists (N = 320), of whom 63% responded. Pulmonologists routinely assessed patients' smoking behaviour and their willingness to quit, but were least experienced in actually assisting patients to quit. Pulmonologists intending to use the method perceived a more supportive social environment in working with it and were more convinced of their ability to use it. Overall, pulmonologists were not convinced that the method would result in more patients quitting, and were pessimistic about their ability to use it. Pulmonologists need to be convinced of the effectiveness of the 4A method and their ability to use it. Skills training and the creation of a social environment supportive toward smoking cessation assistance are recommended.

Abstract
OBJECTIVES We examined tobacco use and cessation among a probability sample of urban men who have sex with men (MSM) living in 4 large US cities. METHODS Of the 2402 men who were eligible for follow-up from a previously recruited probability sample, 1780 (74%) completed tobacco surveys between January and December 1999. RESULTS Current smoking rates were higher for urban MSM (31.4%; 95% confidence interval [CI]=28.6%, 34.3%) than for men in the general population (24.7%; 95% CI=21.2%, 28.2%). Among MSM, 27% were former smokers. A complex set of sociodemographic, tobacco-related, and other factors were associated with cessation. CONCLUSIONS Results support earlier reports that smoking rates are higher for MSM compared with men in the general population. Findings related to cessation underscore the need to target tobacco control efforts for MSM.

Abstract
In rats, stimulus-nicotine associations can be altered by preexposure to the nicotine US (unconditioned stimulus). This alteration differs with the conditioning preparation. In a conditioned taste avoidance preparation, preexposure to nicotine weakens conditioning. In contrast, nicotine preexposure enhances acquisition of a nicotine-conditioned place preference. No one has examined the effects of US preexposure on nicotine locomotor conditioning. In three separate experiments, we assessed the effects of nicotine preexposure on the subsequent expression of conditioned hyperactivity produced by a nicotine US. We found evidence for nicotine-conditioned locomotor sensitization in non-preexposed rats that received repeated pairings of a distinct context with the psychomotor effects of a 0.42 mg/kg dose of nicotine (free base). Conditioning was not observed at lower nicotine doses (0.18 and 0.11 mg/kg) in non-preexposed rats. Preexposure to the 0.42 and 0.18 mg/kg doses of nicotine (3 or 9 days) attenuated acute locomotor suppression and enhanced the development of locomotor sensitization to that same dose. Despite similar qualitative shifts in the locomotor profile induced by preexposure to the nicotine US, conditioned hyperactivity was only altered after 3 or 9 days of preexposure at the 0.18 mg/kg dose. Thus, similar to place conditioning, nicotine preexposure can enhance the subsequent effectiveness of the nicotine US in a locomotor conditioning preparation.

Abstract
To better understand why most persons in drug treatment smoke, we explored patients' views of the relationship between their smoking, methadone, and drug use. Recruiting from four methadone clinics, we held seven focus groups with 68 current smokers, and 10 individual interviews with former smokers. Sessions were audio-taped, transcribed, and coded. Participants were > or =18 years old, smoked > or =5 cigarettes per day, and had used prescription methadone for > or =2 years. Most patients linked smoking, methadone, and drug use in three ways. First, patients said smoking and drug use were complementary. Examples included smoking to reduce methadone after taste and using drugs to reduce smoking-related throat pain. Second, smoking and drug use were similar because they shared cues and withdrawal symptoms. Third, smoking differed from drug use because it had fewer acute consequences. Because smoking, methadone, and drug use are closely interrelated, future addictions research and treatment protocols should address them in combination.

Abstract
PURPOSE Smoking cessation is an important goal for smokers with coronary artery disease (CAD) because it reduces cardiac morbidity and mortality. Effective interventions for cigarette smokers with CAD exist, but they often are considered to be intensive and expensive. Stepped-care interventions have been proposed as a promising way to allocate smoking cessation treatments in a cost-effective manner. Stepped care refers to the practice of initiating treatment with low-intensity intervention and then exposing treatment failures to successively more intense interventions. METHODS To address the efficacy of this approach, 254 cigarette smokers hospitalized with CAD were provided a brief cessation intervention. The participants then were assigned randomly to either a more intensive stepped-care treatment (counseling and nicotine patch therapy) or no additional treatment. Outcomes were point-prevalent abstinence measured 3 months and 1 year after hospital discharge. RESULTS Stepped-care treatment increased smoking cessation rates from 42% to 53% during a 3-month follow-up period (P =.05), but showed little effect at the 1-year follow-up assessment, as evidenced by a cessation rate for the minimal intervention group of 36% versus 39% for the stepped-care group (P =.36). CONCLUSIONS A stepped-care approach to smoking cessation increased short-but not long-term point-prevalent abstinence in patients with CAD. For improvement of long-term effectiveness, refinement of the timing and content of stepped-care interventions needs to occur.

Abstract
BACKGROUND Many smokers give up smoking on their own, but materials giving advice and information may help them and increase the number who quit successfully. OBJECTIVES The aims of this review were to determine the effectiveness of different forms of self-help materials, compared with no treatment and with other minimal contact strategies; the effectiveness of adjuncts to self-help, such as computer generated feedback, telephone hotlines and pharmacotherapy; and the effectiveness of approaches tailored to the individual compared with non-tailored materials. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group trials register using the terms 'self-help', 'manual*' or 'booklet*'. Date of the most recent search March 2002. SELECTION CRITERIA We included randomised trials of smoking cessation with follow-up of at least six months, where at least one arm tested a self-help intervention. We defined self-help as structured programming for smokers trying to quit without intensive contact with a therapist. DATA COLLECTION AND ANALYSIS We extracted data in duplicate on the type of subjects, the nature of the self-help materials, the amount of face to face contact given to subjects and to controls, outcome measures, method of randomisation, and completeness of follow-up. The main outcome measure was abstinence from smoking after at least six months follow-up in patients smoking at baseline. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates when available. Where appropriate, we performed meta-analysis using a fixed effects model. MAIN RESULTS We identified fifty-one trials. Thirty two compared self-help materials to no intervention or tested materials used in addition to advice. In eleven trials in which self-help was compared to no intervention there was a pooled effect that just reached statistical significance (odds ratio 1.24, 95% confidence interval 1.07 to 1.45) This analysis excluded one trial with a strongly positive outcome that introduced significant heterogeneity. Four further trials in which the control group received alternative written materials did not show evidence for an effect of the smoking self-help materials. We failed to find evidence of benefit from adding self-help materials to face to face advice, or to nicotine replacement therapy. There was evidence from fourteen trials using materials tailored for the characteristics of individual smokers that such personalised materials were more effective than standard manuals (ten trials, odds ratio 1.36, 95% confidence interval 1.13 to 1.64) or no materials (three trials, odds ratio 1.80, 95% confidence interval 1.46 to 2.23). A small numbers of trials failed to detect benefit from using additional materials or targetted materials. REVIEWER'S CONCLUSIONS Standard self-help materials may increase quit rates compared to no intervention, but the effect is likely to be small. We failed to find evidence that they have an additional benefit when used alongside other interventions such as advice from a health care professional, or nicotine replacement therapy. There is evidence that materials that are tailored for individual smokers are more effective.

Abstract
BACKGROUND It is increasingly well documented that physical activity (PA) is a key preventive behavior and that visits to a physician provide an important opportunity for advice and counseling. This paper reports on physician counseling behaviors regarding PA and other chronic disease risk factors from a national survey. METHODS A diverse sample of U.S. adults (N=1818), with oversampling of lower-income households, was surveyed about their PA level as well as a host of social, environmental, and physician counseling issues. RESULTS Overall, 28% of respondents reported receiving physician advice to increase their PA level. Of those who received advice, only 38% received help formulating a specific activity plan and 42% received follow-up support. Patients who received advice and support were more likely to be older, nonwhite, and to have more chronic illnesses and more contact with their doctor. CONCLUSIONS Physician advice, counseling, and follow-up are important components of the social-environmental supports needed to increase population PA levels. Health system changes, including teaching communication skills, prompts to use those skills, and system changes to support attention to PA, are needed to extend promotion of PA to more patients.

Nicotine as an Addictive Substance: A Critical Examination of the Basic Concepts and Empirical Evidence. JOURNAL OF DRUG ISSUES 2001.

Abstract
The present review is a critical analysis of the concepts behind and the empirical data supporting the view that tobacco use represents an addiction to nicotine. It deals with general aspects of the notion of addiction, while concentrating on specific problems associated with incorporating nicotine into current frameworks. The notion of addiction suffers from unprecedented definitional difficulties. The definitions offered by various authorities are very different, even contradictory. Definitions that reasonably include nicotine are so broad and vague that they allow many trivial things, such as salt, sugar, and watching television, to be considered addictive. Definitions that exclude the trivia also exclude nicotine. The addiction hypothesis, in general, is strongly shaped by views that certain drugs bring about a molecular level subversion of rationality. The main human evidence for this is verbal reports of smokers who say that they can't quit. On the other hand, the existence of many millions of successful quitters suggests that most people can quit. Some smokers don't quit, but whether they can't is another matter. The addiction hypothesis would be greatly strengthened by the demonstration that any drug of abuse produces special changes in the brain. It has yet to be shown that any drug produces changes in the brain different from those produced by many innocuous substances and events. The effects of nicotine on the brain are similar to those of sugar, salt, exercise, and other harmless substances and events. Apart from numerous conceptual and definitional inadequacies with the addiction concept in general, the notion that nicotine is addictive lacks reasonable empirical support. Nicotine does not have the properties of reference drugs of abuse. There are so many findings that conflict so starkly with the view that nicotine is addictive that it increasingly appears that adhering to the nicotine addiction thesis is only defensible on extra-scientific grounds.

Abstract
OBJECTIVES To better understand conjoint smoking and drinking among young adult emergency department (ED) patients, the purposes of this investigation were: 1) to assess the prevalence of conjoint use; 2) to determine the factors associated with conjoint alcohol use and smoking; and 3) to address the implications for future ED-based investigation of dual-substance intervention. METHODS Data for this investigation were obtained from a battery of questionnaires administered to the routine-care patients during an alcohol screening in the ED, which was part of a larger alcohol intervention study. RESULTS Study findings revealed that a majority of patients with self-reported alcohol-related problems were smokers. In fact, drinkers who smoked were likely to be pack-a-day smokers. Among the study sample, being female, having low education levels (e.g., high school education or less), having some emotional problems, and currently using marijuana were risk factors for conjoint smoking and drinking. CONCLUSIONS Conjoint users were identifiable through brief screening. Given the prevalence of conjoint smoking and alcohol use among the ED sample and a specific set of risk factors, tailored intervention for alcohol and nicotine dependence may be an important and opportunistic clinical ED service.

Abstract
The aim of this study was to analyze whether the intention to quit smoking was associated with other lifestyle habits healthy for the heart, namely a low-fat diet and regular exercise, using variables suggested by the theory of planned behavior. Self-administered postal questionnaires were sent to 3,200 men 30 to 60 years of age residing in Laval, Quebec. With a response rate of 70.9%, 671 respondents (29.6%) were smokers. A significant proportion (43%) had all three risk behaviors--smoking, a high-fat diet, and sedentariness, and 42% had two--smoking and one of the other behaviors. The remaining had a single risk behavior, namely smoking. Regression analysis suggested that a healthy diet and exercise had no significant influence on the intention to quit smoking. However, men who had a stronger intention to quit smoking than others had a more favorable attitude toward the behavior, a stronger perception of approval in achieving it on the part of important referents, stronger perceived behavioral control, and were among those who smoked fewer cigarettes per day, but had made more attempts to quit. These results can assist in designing better heart-health intervention programs for this high-risk population.

Abstract
In response to reports of rising asthma morbidity and mortality, several consensus statements have been drafted to guide the treatment of asthma. More recently, attempts have been made to develop similar guidelines for the management of chronic obstructive pulmonary disease (COPD). Just as the two diseases differ in their pathophysiology, their treatment algorithms have differed. For both disease groups, avoidance of further airway injury is the initial step in treatment. For asthmatics, this is often allergen avoidance, but for patients with COPD the usual inciting factor is cigarette smoking, thereby making smoking cessation the necessary first step. Whereas beta 2-agonist bronchodilators are used as needed in asthma management, regular bronchodilator therapy with anticholinergic drugs is the first-line approach in COPD. The role of anti-inflammatory drugs differs markedly between the two disease groups. Asthmatic patients benefit dramatically from inhaled anti-inflammatory drugs; little or no benefit can be demonstrated for the majority of patients with COPD. In COPD, the role of exercise rehabilitation programs can improve exercise tolerance. For selected patients with COPD with persistent hypoxemia, the use of supplemental oxygen can reduce mortality. For both patient groups, educational interventions can play a valuable role in making patients patients effective partners in their own care.

Abstract
The purpose of this study was to address the following questions: 1) Do smokers with diabetes believe that cigarettes have favorable outcomes associated with diabetes management? 2) Do smokers with diabetes believe that quitting smoking negatively impacts diabetes management? 3) Do smokers with diabetes perceive significant others as being supportive of attempts to quit smoking? and 4) What is the relationship between these factors and attitude toward quitting smoking? Patients with insulin-dependent diabetes mellitus (IDDM) completed a measure of Attitude Toward Quitting Smoking, which assessed desire and confidence in ability to achieve cessation, and the Diabetes and Smoking Beliefs Questionnaire, which assessed beliefs regarding cigarettes and diabetes management. Smokers whose attitudes reflected less desire to quit and less confidence in doing so reported that cigarettes had utility in diabetes management, that quitting has negative effects on diabetes, and perceived significant others as only moderately supportive of attempts to quit smoking. Implications of these findings for diabetes education are discussed.
