Hughes JR. An updated algorithm for choosing among smoking cessation treatments. J Subst Abuse Treat 2013; 45:215-21.

Abstract
Although meta-analyses have documented the efficacy of treatments for smoking cessation, and guidelines have outlined treatment elements, few algorithms for choosing among treatments have been described. The current algorithm updates the author's prior algorithm. The major decisions in the algorithm are (a) use a motivational treatment if the smoker is not currently interested in quitting, (b) assess factors that influence choice of treatment, (c) consider both gradual and abrupt cessation, (d) use combined patch+gum/inhaler/lozenge or varenicline as first line medications, (e) use individual, group, Internet, and phone counseling as first line psychosocial treatments, and (f) continue treatment after a lapse or relapse. Further research is needed to determine whether algorithms improve treatment outcomes.

Abstract
BACKGROUND Recent theoretical and empirical work has led to debate over the benefit of delaying the implementation of a decision to quit smoking in order to plan the attempt. These two need not be linked, planning can occur before a commitment to quit is made, or after it is implemented, as well as in between. This study will test whether there are independent benefits for encouraging smokers to act immediately on a definite decision to quit smoking, and to engage in structured planning. METHODS/DESIGN A complex randomised controlled trial with a factorial design, testing the presence of a recommendation to quit immediately (or not) and encouragement to structured planning (or not) as additions to standard care, a web-based automated tailored advice program (QuitCoach). Participants are recruited from users of the QuitCoach who reside in Australia, do not report a mental health condition for which they are taking medication, are adult daily smokers, and at least open to the possibility of quitting. For the Immediate arm they could not have committed to quit within 2 days, while the Planning arm included all these and those quit within the last 4 days. This creates 6 groups: 2 × 3, with 2 × 2 fully randomised, and 2 only randomised for the planning arm. Follow-up assessments are conducted around 1 month (targeting two weeks after the quit attempt started), and 6 months later. The primary outcome is 6-month sustained abstinence at 6 months. Secondary outcomes include point-prevalence abstinence at both follow-ups, and making quit attempts during the intervention period. We will also explore differences in actual behaviour (timing and planning) by intervention, and relate this to outcomes. DISCUSSION This study will result in a better understanding of the roles of planning and delay in influencing the success of quit attempts.

Turner J, McNeill A, Coleman T, Bee JL, Agboola S. Feasibility of offering nicotine replacement therapy as a relapse prevention treatment in routine smoking cessation services. BMC Health Serv Res 2013; 13:38.

Abstract
Background National Health Service stop smoking services (NHS SSS) in the UK offer cost- effective smoking cessation services. Despite high abstinence rates after acute cessation treatment, the majority of clients have relapsed by one year. Several interventions have been identified, from trial data, as effective in preventing relapse to smoking. This study investigated uptake, feasibility and acceptability of offering nicotine replacement therapy (NRT) as a relapse prevention intervention (RPI) in NHS SSS. Methods Eligible smokers who had successfully completed acute cessation treatment using NRT at Nottingham City NHS SSS between April 2010 and January 2011 were offered the RPI and the rate of uptake was monitored. Consenting individuals completed a baseline questionnaire, providing demographic and smoking behaviour data. The RPI consisted of using NRT for a further 12 weeks after initial cessation-orientated treatment had ended. At a six-month review, self-reported smoking status was assessed via telephone. Anonymised demographic data on NHS SSS users who did not agree to participate in the study were retrieved from NHS SSS records and used to determine the presence of any socio-demographic differences between individuals who agreed to participate in the study and those who did not. Semi-structured telephone interviews were conducted with a selection of participants; these were audio-recorded, transcribed and analysed to identify participants’ views on the RPI. Results Of 493 stop smoking service clients who were assessed, 260 were eligible for and offered the RPI and 115 (44%, CI 38%- 50%) accepted. Individuals who accepted NRT were significantly more likely to be older (p < 0.001) and to pay for their prescriptions (p < 0.001). Quitters who had never worked or were unemployed were significantly less likely to accept the offer of relapse prevention compared to those in routine and manual occupations (55% reduction in odds, p = 0.026). Interview findings revealed that clients who accepted extended NRT felt the longer duration of pharmacological and psychological support were both valuable in helping them to remain abstinent. Conclusion In routine smoking cessation service care, it is feasible to offer clients extended courses of NRT as a RPI. The RPI was acceptable to them as almost half of the eligible clients offered this treatment accepted it.

Abstract
INTRODUCTION Despite an estimated 1 million tobacco-related deaths annually in China, public health officials face overwhelming barriers to implementing effective tobacco control policies and programs. Models of effective tobacco control can be adapted for Chinese tobacco use and culture based on reliable and valid data regarding predictors of smoking and abstaining. METHODS As part of the China Seven Cities Study to assess the role of rapid social, economic, and cultural change on tobacco use and related health practices and outcomes, 4,072 adult male smokers provided data in 3 annual waves. Measures included current smoking, nicotine dependence, readiness for quitting, perceived stress, hostility, depressive symptoms, as well as covariates (e.g., age, marital status, educational attainment, and family income). RESULTS Odds of being abstinent at Wave 3 were increased by: lower nicotine dependence at Wave 1 and becoming less dependent between Waves 1 and 3; progressing beyond the contemplation stage between Waves 1 and 3; perceiving less stress, whether initially at Wave 1 or over time from Wave 1 to Wave 3; and lower hostility scores at Wave 1 and decreased hostility from Wave 1 to Wave 3. Among those who quit, odds of remaining abstinent rather than relapsing by Wave 3 were higher among those who were less dependent at Wave 1 and who became less dependent from Wave 1 to Wave 3; and those who showed decreases in hostility from Wave 1 to Wave 3. CONCLUSIONS The public health challenge posed by very high prevalence of male smoking in China can be met by policies and programs that lead to successful long-term cessation. This can only be done successfully by designing interventions based on knowledge of the country's smokers and the current study suggests several elements.

Abstract
OBJECTIVE Following successful smoking cessation, smokers with schizophrenia are vulnerable to relapse shortly after treatment discontinuation. Our objective was to assess the feasibility and effectiveness of a 12-month relapse prevention intervention in recently abstinent smokers with schizophrenia. METHOD Adult outpatient smokers with schizophrenia received weekly cognitive behavioral therapy groups, bupropion slow release, transdermal nicotine patch, and nicotine gum or lozenge for three months. Subjects with seven-day point prevalence abstinence at month 3 received an additional 12 months (months 4-15) of therapy with bupropion, transdermal nicotine patch, and nicotine gum/lozenge in conjunction with relapse prevention-based cognitive behavioral therapy groups that were held weekly in month 4, biweekly in months 5-6, and monthly in months 7-15. RESULTS Seventeen of 41 participants (41.5%) attained biochemically verified self-report of seven-day point prevalence abstinence at the end of three months of treatment and entered relapse prevention treatment. There was an 81% attendance rate at relapse prevention groups. At the end of the 12-month relapse prevention phase (month 15 overall), 11 of 17 (64.7%) demonstrated biochemically verified seven-day point prevalence abstinence, and 10 of 17 (58.8%) reported four-week continuous abstinence. Almost one quarter of the sample (23.5%) demonstrated long-term prolonged abstinence through the end of the trial. There were no clinically detected cases of psychiatric symptom exacerbation. One participant, who was managed as an outpatient, self-reported psychiatric symptom exacerbation in the interim period between study visits. CONCLUSIONS Extended duration smoking cessation treatment is well-tolerated and may improve smoking outcomes for recently abstinent smokers with schizophrenia. Controlled trials are warranted.

Abstract
BACKGROUND Effective pharmacotherapies are available to help people who are trying to stop smoking, but quitting can still be difficult and providing higher levels of behavioural support may increase success rates further. OBJECTIVES To evaluate the effect of increasing the intensity of behavioural support for people using smoking cessation medications, and to assess whether there are different effects depending on the type of pharmacotherapy, or the amount of support in each condition. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register in July 2012 for records with any mention of pharmacotherapy, including any type of NRT, bupropion, nortriptyline or varenicline that evaluated the addition of personal support or compared two or more intensities of behavioural support. SELECTION CRITERIA Randomized or quasi-randomized controlled trials in which all participants received pharmacotherapy for smoking cessation and conditions differed by the amount of behavioural support. Controls could receive less intensive personal contact, or just written information. We did not include studies that used a contact matched control to evaluate differences between types or components of support. We excluded trials recruiting only pregnant women, trials recruiting only adolescents, and trials with less than six months follow-up. DATA COLLECTION AND ANALYSIS Search results were prescreened by one author and inclusion or exclusion of potentially relevant trials was agreed by both authors. Data were extracted by one author and checked by the other.The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. We calculated the risk ratio (RR) and 95% confidence interval (CI) for each study. Where appropriate, we performed meta-analysis using a Mantel-Haenszel fixed-effect model. MAIN RESULTS Thirty-eight studies met the inclusion criteria with over 15,000 participants in the relevant arms. There was very little evidence of statistical heterogeneity (I² = 3%) so all studies were pooled in the main analysis. There was evidence of a small but statistically significant benefit from more intensive support (RR 1.16, 95% CI 1.09 to 1.24) for abstinence at longest follow-up. All but two of the included studies provided four or more sessions of support. Most trials used nicotine replacement therapy. Significant effects were not detected for studies where the pharmacotherapy was nortriptyline (two trials) or varenicline (one trial), but this reflects the absence of evidence. In subgroup analyses, studies that provided at least four sessions of personal contact for the intervention and no personal contact for the control had slightly larger effects (six trials, RR 1.25, 95% CI 1.08 to 1.45), as did studies where all intervention counselling was via telephone (six trials, RR 1.28, 95% CI 1.17 to 1.41). Weaker evidence for a benefit of providing additional behavioural support was seen in the trials where all participants, including those in the control condition, had at least 30 minutes of personal contact (18 trials, RR 1.11, 95% CI 0.99 to 1.25). None of the differences between subgroups were significant, and the last two subgroup analyses were not prespecified. No trials were judged at high risk of bias on any domain. AUTHORS' CONCLUSIONS Providing behavioural support in person or via telephone for people using pharmacotherapy to stop smoking has a small but important effect. Increasing the amount of behavioural support is likely to increase the chance of success by about 10 to 25%, based on a pooled estimate from 38 trials. A subgroup analysis of a small number of trials suggests the benefit could be a little greater when the contrast is between a no contact control and a behavioural intervention that provides at least four sessions of contact. Subgroup analysis also suggests that there may be a smaller incremental benefit from providing even more intensive support via more or longer sessions over and above some personal contact.

Do risk factors for post-partum smoking relapse vary according to marital status? Matern Child Health J 2012; 16:1364-73.

Abstract
We aimed to examine associations between factors readily obtainable in health care settings and post-partum smoking relapse in women of differing marital status. We analysed data on 1,829 mothers in the Millennium Cohort Study who reported quitting smoking during their pregnancy using multivariate logistic regression. We analysed single, married and cohabiting women separately. Fifty-seven percent of mothers who quit during pregnancy had relapsed at 9 months. The risk of relapse was highest for single women, followed by cohabiting, then married women. Higher parity and not managing financially were associated with relapse for single women. For married women the greatest risk of relapse was associated with having a partner who also relapsed. Women whose husbands continued to smoke had an increased risk of relapse but those whose husbands had sustained a quit were protected. Other significant risk factors were not breastfeeding, having other children and drinking at moderate frequencies. A similar pattern was seen for cohabiting women, except that having a partner who quit but then relapsed did not appear to confer an additional risk. Drinking at moderate intervals (only) was associated with relapse but breastfeeding and parity were not. The association between married couple relapse was not evident when only the husband's smoking status during the pregnancy was considered, indicating that partner follow-up is important post-partum. Risk factors for relapse appear to differ according to marital status. A 'one size fits all' package of post-partum relapse prevention is unlikely to be an appropriate intervention strategy.

Abstract
AIMS The NHS Stop Smoking Service (NHS-SSS) helps approximately half its clients to quit for 4 weeks. However, most initially successful quitters relapse within 6 months. Short message service (SMS) texting has been shown to facilitate stopping smoking. We describe the development, implementation and subsequent evaluation, in terms of practicability and client response, of an SMS text-based relapse prevention intervention (RPI) delivered within routine community and specialist National Health Service (NHS) Stop Smoking Service (SSS) provision in four Primary Care Trusts. DESIGN Text messages aimed at motivation to remain abstinent, preventing careless lapses and continuing the full course of medicine for smoking cessation were developed and sent weekly to clients' mobile phones for 12 weeks and fortnightly for 6 months. They were asked to respond to some of the texts and contact the NHS SSS if they lapsed. They were also offered free nicotine mini lozenges to be sent via the mail on three occasions. SETTING NHS SSS. PARTICIPANTS 202 clients who had been abstinent for 4 weeks. MEASUREMENTS Feasibility of introducing RPI into routine care; response to interactive messages and requests for the medication; rating of the helpfulness of RPI; self-reported and carbon monoxide (CO)-validated smoking status for up to 26 weeks. FINDINGS A text-based RPI was easy to implement within the NHS SSS provided by specialist advisers, but enrollment of clients from services provided by a network of pharmacists was difficult because client contact details were often lacking. Where records of the number of people invited to RPI were available, 94% of eligible participants enrolled. The RPI was well received by both SSS clients and staff, with 70% (n = 63) of clients who completed follow-up considering the intervention helpful. Eighty-five per cent (n = 172) of clients responded to at least one of the nine interactive text messages. Sixty-four clients (32% of the total, 47% of those we managed to contact) reported continuous abstinence at 6 months. Eighteen (9%) clients who relapsed to smoking used the RPI to re-engage with the NHS SSS and 10 (5%) successfully re-established abstinence. CONCLUSIONS In smokers attending National Health Service Stop Smoking Services who are abstinent 4 weeks after their quit date, a relapse prevention intervention based on SMS text messaging was well received, and can be implemented economically and rapidly. A controlled trial is needed to establish whether it has a significant impact on relapse.

Abstract
Tobacco use, especially cigarette smoking, is higher than average in persons living with HIV/AIDS (PLWHA). The Public Health Service Clinical Practice Guideline for Treating Tobacco Use and Dependence states that, during every medical encounter, all smokers should be offered smoking cessation counseling, along with approved medications. The Guideline also recognizes PLWHA as a priority population, given the scarcity of research on effective cessation treatments in this group. The scant evidence suggests that conventional treatments, though worthwhile, are not as successful as might be hoped for. The reasons for this are not entirely clear, but may have to do with the complex array of medical and psychosocial factors that complicate their lives. Clinicians should consider re-treatment strategies for those patients who encounter difficulty when quitting smoking with conventional approaches, switching or augmenting treatments as needed to minimize adverse experiences, and to maximize tolerability, adherence, and cessation outcomes.

Abstract
OBJECTIVES We tested a series of self-help booklets designed to prevent postpartum smoking relapse. METHODS We recruited 700 women in months 4 through 8 of pregnancy, who quit smoking for their pregnancy. We randomized the women to receive either (1) 10 Forever Free for Baby and Me (FFB) relapse prevention booklets, mailed until 8 months postpartum, or (2) 2 existing smoking cessation materials, as a usual care control (UCC). Assessments were completed at baseline and at 1, 8, and 12 months postpartum. RESULTS We received baseline questionnaires from 504 women meeting inclusion criteria. We found a main effect for treatment at 8 months, with FFB yielding higher abstinence rates (69.6%) than UCC (58.5%). Treatment effect was moderated by annual household income and age. Among lower income women (< $30 000), treatment effects were found at 8 and 12 months postpartum, with respective abstinence rates of 72.2% and 72.1% for FFB and 53.6% and 50.5% for UCC. No effects were found for higher income women. CONCLUSIONS Self-help booklets appeared to be efficacious and offered a low-cost modality for providing relapse-prevention assistance to low-income pregnant and postpartum women.

Abstract
The association between smoking during pregnancy and adverse maternal/neonatal health outcomes is widely acknowledged, and recent health care reform has filled a much-needed gap by extending prenatal smoking cessation intervention coverage to all pregnant women on Medicaid. While more extensive coverage will improve quit rates during pregnancy, there continues to be a need to address high relapse rates in the postpartum period for both the insured and the uninsured. Smoking during the postpartum period exposes infants directly and indirectly to negative health effects, and has additional costs to mothers and society. Approximately 80% of women who quit smoking during pregnancy relapse in the first year postpartum, highlighting a need for effective continuing care that supports them through the challenging postpartum period when stress is high and motivations to stay quit may change. Existing relapse prevention interventions, typically delivered during pregnancy, have been found to be of little benefit during the postpartum period, suggesting the need for a more formal continuing care approach. Phone-based protocols are promising because they address the need for flexible access, and are known to be effective at increasing quit rates and sustained cessation.

Abstract
BACKGROUND Smoking in pregnancy is a substantial public health problem. When used by non-pregnant smokers, pharmacotherapies [nicotine replacement therapy (NRT), bupropion and varenicline] are effective treatments for smoking cessation, however, their efficacy and safety in pregnancy remains unknown. OBJECTIVES To determine the efficacy and safety of smoking cessation pharmacotherapies, including NRT, varenicline and bupropion (or any other medications) when used to support smoking cessation in pregnancy. SEARCH METHODS We searched the Pregnancy and Childbirth Group's Trials Register (5 March 2012), checked references of retrieved studies and contacted authors in the field. SELECTION CRITERIA Randomised controlled trials (RCTs) with designs that permit the independent effects of any type of NRT (e.g. patch, gum etc.) or any other pharmacotherapy on smoking cessation to be ascertained were eligible for inclusion. Trials must provide very similar (ideally identical) levels of behavioural support or cognitive behaviour therapy (CBT) to participants in active drug and comparator trial arms.The following RCT designs are considered acceptable.Placebo RCTs: any form of NRT or other pharmacotherapy, with or without behavioural support/CBT, or brief advice compared with placebo NRT and additional support of similar intensity.RCTs providing a comparison between i) behavioural support/CBT or brief advice and ii) any form of NRT or other pharmacotherapy added to behavioural support of similar (ideally identical) intensity.Parallel- or cluster-randomised design trials are eligible for inclusion. However, quasi-randomised, cross-over and within-participant designs are not eligible for inclusion due to the potential biases associated with these designs. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias and extracted data. Two assessors independently extracted data and cross checked individual outcomes of this process to ensure accuracy. The primary efficacy outcome was smoking cessation in later pregnancy (in all but one trial, at or around delivery); safety was assessed by seven birth outcomes that indicated neonatal well being and we also collated data on adherence. MAIN RESULTS Six trials of NRT enrolling 1745 pregnant smokers were included; we found no trials of varenicline or bupropion. No statistically significant difference was seen for smoking cessation in later pregnancy after using NRT as compared to control (risk ratio (RR) 1.33, 95% confidence interval (CI) 0.93 to 1.91, six studies, 1745 women). Subgroup analysis comparing placebo-RCTs with those which did not use placebos found that efficacy estimates for cessation varied with trial design (placebo RCTs, RR 1.20, 95% CI 0.93 to 1.56, four studies, 1524 women; non-placebo RCTs, RR 7.81, 95% CI 1.51 to 40.35, two studies, 221 women; P value for random-effects subgroup interaction test = 0.03). There were no statistically significant differences in rates of miscarriage, stillbirth, premature birth, birthweight, low birthweight, admissions to neonatal intensive care or neonatal death between NRT or control groups. AUTHORS' CONCLUSIONS Nicotine replacement therapy is the only pharmacotherapy for smoking cessation that has been tested in RCTs conducted in pregnancy. There is insufficient evidence to determine whether or not NRT is effective or safe when used to promote smoking cessation in pregnancy or to determine whether or not using NRT has positive or negative impacts on birth outcomes. Further research evidence of efficacy and safety is needed, ideally from placebo-controlled RCTs that investigate higher doses of NRT than were tested in the included studies.

Abstract
Background Web-based computer-tailored approaches have the potential to be successful in supporting smoking cessation. However, the potential effects of such approaches for relapse prevention and the value of incorporating action planning strategies to effectively prevent smoking relapse have not been fully explored. The Stay Quit for You (SQ4U) study compared two Web-based computer-tailored smoking relapse prevention programs with different types of planning strategies versus a control group. Objectives To assess the efficacy of two Web-based computer-tailored programs in preventing smoking relapse compared with a control group. The action planning (AP) program provided tailored feedback at baseline and invited respondents to do 6 preparatory and coping planning assignments (the first 3 assignments prior to quit date and the final 3 assignments after quit date). The action planning plus (AP+) program was an extended version of the AP program that also provided tailored feedback at 11 time points after the quit attempt. Respondents in the control group only filled out questionnaires. The study also assessed possible dose–response relationships between abstinence and adherence to the programs. Methods The study was a randomized controlled trial with three conditions: the control group, the AP program, and the AP+ program. Respondents were daily smokers (N = 2031), aged 18 to 65 years, who were motivated and willing to quit smoking within 1 month. The primary outcome was self-reported continued abstinence 12 months after baseline. Logistic regression analyses were conducted using three samples: (1) all respondents as randomly assigned, (2) a modified sample that excluded respondents who did not make a quit attempt in conformance with the program protocol, and (3) a minimum dose sample that also excluded respondents who did not adhere to at least one of the intervention elements. Observed case analyses and conservative analyses were conducted. Results In the observed case analysis of the randomized sample, abstinence rates were 22% (45/202) in the control group versus 33% (63/190) in the AP program and 31% (53/174) in the AP+ program. The AP program (odds ratio 1.95, P = .005) and the AP+ program (odds ratio 1.61, P = .049) were significantly more effective than the control condition. Abstinence rates and effects differed per sample. Finally, the results suggest a dose–response relationship between abstinence and the number of program elements completed by the respondents. Conclusion Despite the differences in results caused by the variation in our analysis approaches, we can conclude that Web-based computer-tailored programs combined with planning strategy assignments and feedback after the quit attempt can be effective in preventing relapse 12 months after baseline. However, adherence to the intervention seems critical for effectiveness. Finally, our results also suggest that more research is needed to assess the optimum intervention dose.

Abstract
BACKGROUND Cell phone text messaging is gaining increasing recognition as an important tool that can be harnessed for prevention and intervention programs across a wide variety of health research applications. Despite the growing body of literature reporting positive outcomes, very little is available about the design decisions that scaffold the development of text messaging-based health interventions. What seems to be missing is documentation of the thought process of investigators in the initial stages of protocol and content development. This omission is of particular concern because many researchers seem to view text messaging as the intervention itself instead of simply a delivery mechanism. Certainly, aspects of this technology may increase participant engagement. Like other interventions, however, the content is a central driver of the behavior change. OBJECTIVE To address this noted gap in the literature, we discuss the protocol decisions and content development for SMS Turkey (or Cebiniz birakin diyor in Turkish), a smoking cessation text messaging program for adult smokers in Turkey. METHODS Content was developed in English and translated into Turkish. Efforts were made to ensure that the protocol and content were grounded in evidence-based smoking cessation theory, while also reflective of the cultural aspects of smoking and quitting in Turkey. RESULTS Methodological considerations included whether to provide cell phones and whether to reimburse participants for texting costs; whether to include supplementary intervention resources (eg, personal contact); and whether to utilize unidirectional versus bidirectional messaging. Program design considerations included how messages were tailored to the quitting curve and one's smoking status after one's quit date, the number of messages participants received per day, and over what period of time the intervention lasted. CONCLUSION The content and methods of effective smoking cessation quitline programs were a useful guide in developing SMS Turkey. Proposed guidelines in developing text messaging-based behavior change programs are offered.

Abstract
BACKGROUND Alcohol and tobacco are often used together, and alcoholism is much more common among smokers compared with nonsmokers. Studies in humans suggest that nicotine (an active ingredient in cigarette smoke) can increase the consumption of alcohol. Research on rats and mice demonstrated mixed results; some studies report that nicotine increases alcohol consumption, while others show a decrease in drinking. Because cigarette smoke includes many other chemicals, these also may play a significant role in alcohol consumption. For example, 2 of these other constituents, monoamine oxidase inhibitors and acetaldehyde, increase alcohol tolerance and/or alcohol consumption in rodents. This study was designed to investigate how cigarette smoke from tobacco may modify self-administration of alcohol in adolescent C57BL/6 mice, a critical time when adolescent humans begin abusing drugs. METHODS C57BL/6 male mice (4 to 5 weeks old) were acclimated for 3 weeks to consume a 10% (w/v) alcohol solution during a 2-hour daily access in the dark. Subsequently, half the animals were exposed to cigarette smoke for 6 h/d for 16 days. The remaining animals (control) were placed in a smoke-free adjacent chamber. Immediately following the 6-hour period in the chambers, the control and smoke-exposed mice were given access to the 10% alcohol solution for 2 hours. RESULTS Animals exposed to cigarette smoke for 6 h/d consumed approximately 3- to 5-fold more alcohol than the mice in the control group throughout the 16-day study. The mice in the smoke group had a blood alcohol concentration that was nearly 4-fold that of the control mice. CONCLUSIONS Cigarette smoke increases alcohol consumption several fold higher than reported studies using nicotine treatment alone in adolescent rodents. Thus, this model should be useful to determine the roles of other bioactive components in cigarette smoke that may be important in the high co-abuse of smoking and alcohol consumption.

Abstract
AIMS Smokers who lapse during a cessation attempt are at particularly high risk of relapse, so interventions to help smokers recover from lapses are urgently needed. Two recent studies have suggested continuing to use nicotine patches following a lapse may be a beneficial relapse prevention strategy. However, to date no study that uses approved doses of nicotine patches under real-world conditions has tested this hypothesis. DESIGN AND SETTING Clinical trial conducted across eight US study sites. PARTICIPANTS AND MEASUREMENTS Using data from 509 subjects (240 active; 269 placebo) who lapsed during weeks 3-5 of treatment in a randomized, double-blind placebo-controlled trial of 21-mg nicotine patches, we examined whether active nicotine patch use improved the chances of recovering abstinence (7-day point-prevalence) at weeks 6 and 10. FINDINGS Active patch use (versus placebo) increased the likelihood of recovery from a lapse both at 6 weeks [8.3% versus 0.8%; relative risk (RR) = 11.0, P < 0.001] and at 10 weeks (9.6% versus 2.6%; RR = 3.7, P < 0.001). CONCLUSIONS Continuing treatment to aid smoking cessation with active patches promotes recovery from lapses. Smokers should be encouraged to persist with patch treatment if they lapse to smoking.

Abstract
Background Distributing a multiple computer-tailored smoking cessation intervention through the Internet has several advantages for both provider and receiver. Most important, a large audience of smokers can be reached while a highly individualized and personal form of feedback can be maintained. However, such a smoking cessation program has yet to be developed and implemented in the Netherlands. Objective To investigate the effects of a Web-based multiple computer-tailored smoking cessation program on smoking cessation outcomes in a sample of Dutch adult smokers. Methods Smokers were recruited from December 2009 to June 2010 by advertising our study in the mass media and on the Internet. Those interested and motivated to quit smoking within 6 months (N = 1123) were randomly assigned to either the experimental (n = 552) or control group (n = 571). Respondents in the experimental group received the fully automated Web-based smoking cessation program, while respondents in the control group received no intervention. After 6 weeks and after 6 months, we assessed the effect of the intervention on self-reported 24-hour point prevalence abstinence, 7-day point prevalence abstinence, and prolonged abstinence using logistic regression analyses. Results Of the 1123 respondents, 449 (40.0%) completed the 6-week follow-up questionnaire and 291 (25.9%) completed the 6-month follow-up questionnaire. We used a negative scenario to replace missing values. That is, we considered respondents lost to follow-up to still be smoking. The computer-tailored program appeared to have significantly increased 24-hour point prevalence abstinence (odds ratio [OR] 1.85, 95% confidence interval [CI] 1.30–2.65), 7-day point prevalence abstinence (OR 2.17, 95% CI 1.44–3.27), and prolonged abstinence (OR 1.99, 95% CI 1.28–3.09) rates reported after 6 weeks. After 6 months, however, no intervention effects could be identified. Results from complete-case analyses were similar. Conclusions The results presented suggest that the Web-based computer-tailored smoking cessation program had a significant effect on abstinence reported after a 6-week period. At the 6-month follow-up, however, no intervention effects could be identified. This might be explained by the replacement of missing values on the primary outcome measures due to attrition using a negative scenario. While results were similar when using a less conservative scenario (ie, complete-case analyses), the results should still be interpreted with caution. Further research should aim at identifying strategies that will prevent high attrition in the first place and, subsequently, to identify the best strategies for dealing with missing data when studies have high attrition rates.

Abstract
Background Most people who stop smoking successfully for a few weeks will return to smoking again in the medium term. There are few effective interventions to prevent this relapse and none used routinely in clinical practice. A previous exploratory meta-analysis suggested that self-help booklets may be effective but requires confirmation. This trial aims to evaluate the effectiveness and cost-effectiveness of a set of self-help educational materials to prevent smoking relapse in the National Health Service (NHS) Stop Smoking Service. Methods/design This is an open, randomized controlled trial. The target population is carbon monoxide (CO) verified quitters at four weeks in the NHS stop smoking clinic (total sample size N = 1,400). The experimental intervention tested is a set of eight revised Forever Free booklets, including an introduction booklet and more extensive information on all important issues for relapse prevention. The control intervention is a leaflet that has no evidence to suggest it is effective but is currently given to some patients using NHS stop smoking services. Two follow-up telephone interviews will be conducted at three and 12 months after the quit date. The primary outcome will be prolonged abstinence from months four to 12 with no more than five lapses, confirmed by a CO test at the 12-month assessment. The secondary outcomes will be seven-day self-report point prevalence abstinence at three months and seven-day biochemically confirmed point prevalence abstinence at 12 months. To assess cost-effectiveness, costs will be estimated from a health service perspective and the EQ-5D will be used to estimate the QALY (Quality Adjusted Life Year) gain associated with each intervention. The comparison of smoking abstinence rates (and any other binary outcomes) between the two trial arms will be carried out using odds ratio as the outcome statistic and other related statistical tests. Exploratory subgroup analyses, including logistic regression analyses with interaction terms, will be conducted to investigate possible effect-modifying variables. Discussion The possible effect of self-help educational materials for the prevention of smoking relapse has important public health implications.

Abstract
OBJECTIVES To investigate the links between health warning labels (WLs) on cigarette packets and relapse among recently quit smokers. DESIGN Prospective longitudinal cohort survey. SETTING Australia, Canada, the UK and the USA. PARTICIPANTS 1936 recent ex-smokers (44.4% male) from one of the first six waves (2002-2007) of the International Tobacco Control 4-Country policy evaluation survey, who were followed up in the next wave. MAIN OUTCOME MEASURES Whether participants had relapsed at follow-up (approximately 1 year later). RESULTS In multivariate analysis, very frequent noticing of WLs among ex-smokers was associated with greater relapse 1 year later (OR: 1.52, 95% CI 1.11 to 2.09, p<0.01), but this effect disappeared after controlling for urges to smoke and self-efficacy (OR: 1.29, 95% CI 0.92 to 1.80, p=0.135). In contrast, reporting that WLs make staying quit 'a lot' more likely (compared with 'not at all' likely) was associated with a lower likelihood of relapse 1 year later (OR: 0.65, 95% CI 0.49 to 0.86, p<0.01) and this effect remained robust across all models tested, increasing in some. CONCLUSIONS This study provides the first longitudinal evidence that health warnings can help ex-smokers stay quit. Once the authors control for greater exposure to cigarettes, which is understandably predictive of relapse, WL effects are positive. However, it may be that ex-smokers need to actively use the health consequences that WLs highlight to remind them of their reasons for quitting, rather than it being something that happens automatically. Ex-smokers should be encouraged to use pack warnings to counter urges to resume smoking. Novel warnings may be more likely to facilitate this.

Abstract
OBJECTIVE Maternal smoking during pregnancy is associated with a reduction in birth size but very few studies have collated changes in neonatal anthropometry. Our aims were both to assess body composition differences by anthropometry between new-borns from smoking mothers and those from non-smoking mothers, and to show whether these differences affect proportional body mass distribution. METHODS Caucasian mothers and their full term singleton new-borns (N=1216) were selected during 2009. A structured questionnaire was completed regarding obstetric and demographic data, as well as tobacco consumption. Women were categorized, according to their smoking habits, into a non-smoking group (never smoked or stopped smoking prior to pregnancy) and a smoking group (smoked throughout pregnancy). RESULTS 22.1% of mothers smoked during pregnancy (median: 6 cigarettes/day, range: l-40). Smoking mothers were significantly younger than non-smoking mothers but there were no differences regarding other aspects which could affect infant weight. Infants from non-smoking mothers were heavier, longer, and body circumferences were all larger than those from smoking mothers (p<0.001), but the Ponderal Index showed no statistical differences. Skinfold thicknesses were significantly lower in new-borns from smoking mothers but these differences were less evident than those from body size. Subcutaneous fat distribution did not show statistical differences between the two groups. After gestational age, to smoke during gestation is the second main determinant of birth weight. CONCLUSIONS Smoking during pregnancy involves a generalized reduction of most axiological parameters as a result of proportionate fetal growth impairment. In those infants born from mothers who smoked during gestation, neonatal lean body mass appears to be more affected than body fat, and distribution of subcutaneous fat is not different.

Abstract
AbstractAims:Most smokers who quit smoking usually relapse. Smoking relapse prevention programs are thus needed and their optimal content and duration should be therefore studied. The present study aimed to compare the efficacy of two relapse prevention programs designed for subjects who reported to be abstinent after a smoking cessation program and to assess predictors of abstinence 9 months later.Participants and design:Two-hundred and seventy-five adults who reported to be abstinent were randomised in two 9-month relapse prevention programs: Workplace Group Counselling Program (WGC) or Proactive Phone Counselling Program (PPC).Measurements:Assessment included questionnaires (Brief Symptom Inventory, BSI; Dutch Eating Behavior Questionnaire, DEBQ; Life Event Scale; sociodemographic and companies' characteristics; and companies' policy toward smoking), and abstinence measurements (self-report, breath carbon monoxide level and urinary cotinine concentration level).Findings:Quit rates at 9 months were respectively 57.5% in the PPC arm and 61.7% in the WGC arm (p= .552). Regression analysis indicated that urinary cotinine concentration level lower than or equal to 317ng/ml was associated with higher rate of abstinence (OR= 4.75, 95% CI = 1.23–18.30,p= .024). Moreover having higher BSI global severity index (OR= .36; 95% CI = .15–.83;p= .017), DEBQ external eating scores (OR= .67; 95% CI = .45–1.00;p= .050) and a free program (OR= .46; 95% CI = .22–.99;p= .048) were associated with lower rate of abstinence.Conclusions:Efficacy was similar for the two programs. This study underlines the need to monitor distress, eating behaviours, lapses and motivation, and to include in future relapse prevention programs specific psychological and/or pharmacological interventions that consider these dimensions.

Abstract
Background and Objective A high proportion of low-income people insured by the Medicaid program smoke. Earlier research concerning a comprehensive tobacco cessation program implemented by the state of Massachusetts indicated that it was successful in reducing smoking prevalence and those who received tobacco cessation benefits had lower rates of in-patient admissions for cardiovascular conditions, including acute myocardial infarction, coronary atherosclerosis and non-specific chest pain. This study estimates the costs of the tobacco cessation benefit and the short-term Medicaid savings attributable to the aversion of inpatient hospitalization for cardiovascular conditions. Methods A cost-benefit analysis approach was used to estimate the program's return on investment. Administrative data were used to compute annual cost per participant. Data from the 2002–2008 Medical Expenditure Panel Survey and from the Behavioral Risk Factor Surveillance Surveys were used to estimate the costs of hospital inpatient admissions by Medicaid smokers. These were combined with earlier estimates of the rate of reduction in cardiovascular hospital admissions attributable to the tobacco cessation program to calculate the return on investment. Findings Administrative data indicated that program costs including pharmacotherapy, counseling and outreach costs about $183 per program participant (2010 $). We estimated inpatient savings per participant of $571 (range $549 to $583). Every $1 in program costs was associated with $3.12 (range $3.00 to $3.25) in medical savings, for a $2.12 (range $2.00 to $2.25) return on investment to the Medicaid program for every dollar spent. Conclusions These results suggest that an investment in comprehensive tobacco cessation services may result in substantial savings for Medicaid programs. Further federal and state policy actions to promote and cover comprehensive tobacco cessation services in Medicaid may be a cost-effective approach to improve health outcomes for low-income populations.

Abstract
Cigarette smoking is a social behavior. Smoking is also accompanied by distinctive gustatory and olfactory stimulation. However, none of these factors affecting nicotine intake are modeled in existing preclinical studies. We report a novel model of adolescent nicotine self-administration (SA) in rats where licking on drinking spouts was used as the operant behavior to activate the concurrent delivery of nicotine (i.v.) and an appetitive olfactogustatory (OG) cue, and social interaction was required for stable SA. The operant chamber was divided by a panel that separated the SA rat and another rat serving as the demonstrator, who had free access to the OG cue but did not receive nicotine. Orofacial contacts were permitted by the divider. Conditioned taste aversion prevented solo rats to self-administer nicotine. However, stable nicotine (15-30 μg/kg, free base) SA was established in the presence of demonstrator rats with free access to the OG cue. Omitting the olfactory component of the cue prevented the acquisition of nicotine SA. Mecamylamine, a nicotinic antagonist, reduced licking behavior. Familiar peers were more effective demonstrators in facilitating the acquisition of nicotine SA than were unfamiliar rats. No sex difference in nicotine intake was found. These data indicate that the contingent OG cue is associated with the aversive property of nicotine that prevents subsequent drug intake. Social information encoded in olfaction not only permits the establishment of stable nicotine SA but also enhances nicotine intake. These findings implicate adolescent social interactions in promoting smoking behavior by surmounting the aversive property of nicotine.

Abstract
Despite a strong stance by the American College Health Association and years of prevention and control efforts on US college campuses, smoking and exposure to secondhand smoke remain a problem among college students. This article provides an overview of what is known about cigarette smoking in this population as well as existing interventions for smoking prevention, cessation, and exposure to secondhand smoke on college campuses. Strategies to reduce tobacco use are presented, many of which have been demonstrated to be effective in the short-term.

Abstract
Relapse is the rule rather than the exception among smokers attempting to quit, and compared to men, women may have higher relapse rates. The current study was a randomized clinical trial testing a palmtop computer-delivered treatment (CDT) for smoking relapse prevention among women. The intervention was individualized based on key theoretical constructs that were measured using ecological momentary assessment (EMA). All participants (N = 302) received standard smoking cessation treatment consisting of nicotine replacement therapy and group counseling, and completed EMA procedures for one week after quitting. At the completion of the group counseling sessions and EMA procedures, participants were randomized to either CDT or no further computer-delivered treatment or assessment (EMA-Only). CDT participants received a palmtop computer-delivered relapse prevention treatment for one additional month. CDT did not improve abstinence rates relative to EMA-Only. Process analyses suggested that heavier smokers were more likely to use CDT and that greater use among CDT participants may be associated with more positive outcomes. The rapid pace of technological advances in mobile computer technology and the ubiquity of such devices provide a novel platform for developing new and potentially innovative treatments. However, the current study did not demonstrate the efficacy of such technology in improving treatment outcomes.

Abstract
The aim of the present study was to evaluate the smoking relapse rate among smokers who had become abstinent during admission for acute coronary syndromes. The association between smoking relapse and mortality was also analyzed. A cohort of 1,294 consecutive active smokers who had interrupted smoking after admission for acute coronary syndromes (1,018 men and 276 women, mean age 59.7 ± 12.3 years) was followed up for 12 months after the index admission. All patients received a brief in-hospital smoking cessation intervention consisting of repeated counseling sessions. During follow-up, 813 patients (62.8%) resumed regular smoking (median interval to relapse 19 days, interquartile range 9 to 76). Increasing age (hazard ratio [HR] 1.034 per year, 95% confidence interval [CI] 1.028 to 1.039, p = 0.001) and female gender (HR 1.23, 95% CI 1.09 to 1.42, p = 0.03) were independent predictors of smoking relapse. Patients enrolled in a cardiac rehabilitation program (HR 0.74, 95% CI 0.51 to 0.91, p = 0.02) and those with diabetes (HR 0.79, 95% CI 0.68 to 0.94, p = 0.03) were more likely to remain abstinent. During follow-up, 97 patients died (1-year probability of death 0.075, 95% CI 0.061 to 0.090). Multivariate analysis with the Cox proportional hazard regression method, including smoking relapse as a time-dependent covariate, demonstrated that, after adjustment for patient demographics, the clinical history features and variables related to the index event, the resumption of smoking was an independent predictor of total mortality (HR 3.1, 95% CI 1.3 to 5.7, p = 0.004). In conclusion, smoking relapse after acute coronary syndromes is associated with increased mortality, and counseling interventions should be integrated into the postdischarge support to reduce the negative effects of smoking resumption.

Abstract
Inflammatory bowel disease is a chronic condition with a pathogenic background that involves both genetic and environmental factors. Although important progress has been made regarding the former in the last decade, scarce knowledge is available for the latter. In this sense, smoking remains the most important environmental factor in IBD. Active smoking increases the risk of developing Crohn's disease (CD). Moreover, CD patients who start or continue smoking after disease diagnosis are at risk for poorer outcomes such as higher therapeutic requirements and disease-related complications, as compared to those patients who quit smoking or who never smoked. However, the harmful effect of active smoking is not uniform in all patients or in all clinical scenarios. Interventions designed to facilitate smoking cessation may impact the course of the disease. In this article, the available evidence of the deleterious effects of smoking on CD is reviewed in detail, and alternative therapeutic approaches to CD in smokers are proposed.

Policies and legal requirements with respect to drug testing of newborns may vary by jurisdiction, and caregivers should be familiar with the regulations in their region. (III-A) 4. Health care providers should employ a flexible approach to the care of women who have substance use problems, and they should encourage the use of all available community resources. (II-2B) 5. Women should be counselled about the risks of periconception, antepartum, and postpartum drug use. (III-B) 6. Smoking cessation counselling should be considered as a first-line intervention for pregnant smokers. (I-A) Nicotine replacement therapy and/or pharmacotherapy can be considered if counselling is not successful. (I-A) 7. Methadone maintenance treatment should be standard of care for opioid-dependent women during pregnancy. (II-IA) Other slow-release opioid preparations may be considered if methadone is not available. (II-2B) 8. Opioid detoxification should be reserved for selected women because of the high risk of relapse to opioids. (II-2B) 9. Opiate-dependent women should be informed that neonates exposed to heroin, prescription opioids, methadone, or buprenorphine during pregnancy are monitored closely for symptoms and signs of neonatal withdrawal (neonatal abstinence syndrome). (II-2B) Hospitals providing obstetric care should develop a protocol for assessment and management of neonates exposed to opiates during pregnancy. (III-B) 10. Antenatal planning for intrapartum and postpartum analgesia may be offered for all women in consultation with appropriate health care providers. (III-B) 11. The risks and benefits of breastfeeding should be weighed on an individual basis because methadone maintenance therapy is not a contraindication to breastfeeding. (II-3B).

Abstract
The Relapse Prevention (RP) model has been a mainstay of addictions theory and treatment since its introduction three decades ago. This paper provides an overview and update of RP for addictive behaviors with a focus on developments over the last decade (2000-2010). Major treatment outcome studies and meta-analyses are summarized, as are selected empirical findings relevant to the tenets of the RP model. Notable advances in RP in the last decade include the introduction of a reformulated cognitive-behavioral model of relapse, the application of advanced statistical methods to model relapse in large randomized trials, and the development of mindfulness-based relapse prevention. We also review the emergent literature on genetic correlates of relapse following pharmacological and behavioral treatments. The continued influence of RP is evidenced by its integration in most cognitive-behavioral substance use interventions. However, the tendency to subsume RP within other treatment modalities has posed a barrier to systematic evaluation of the RP model. Overall, RP remains an influential cognitive-behavioral framework that can inform both theoretical and clinical approaches to understanding and facilitating behavior change.

Abstract
BACKGROUND Smoking cessation is essential after the diagnosis of cancer to enhance clinical outcomes. Although effective smoking-cessation treatments are available, <50% of smokers with cancer report receiving treatment. Reasons for the low dissemination of such treatment are unclear. METHODS Data were collected from questionnaires and medical record reviews from 160 smokers or recent quitters with lung or head and neck cancer. Descriptive statistics, Cronbach alpha coefficients, and logistic regression were used in the analyses. The median age of participants was 57 years, 63% (n = 101) were men, 93% (n = 149) were white, and 57% (n = 91) had lung cancer. RESULTS Eight-six percent (n = 44) of smokers and 75% (n = 82) of recent quitters reported that healthcare providers gave advice to quit smoking. Sixty-five percent (n = 33) of smokers and 47% (n = 51) of recent quitters reported that they were offered assistance from their healthcare providers to quit smoking. Fifty-one percent (n = 26) of smokers and 20% (n = 22) of recent quitters expressed an interest in a smoking-cessation program. An individualized smoking-cessation program was the preferred type of program. Among smokers, younger patients with early stage disease and those with partners who were smokers were more interested in programs. CONCLUSIONS Although the majority of patients received advice and were offered assistance to quit smoking, approximately 50% of smokers were interested in cessation programs. Innovative approaches to increase interest in cessation programs need to be developed and tested in this population.

Abstract
OBJECTIVES To identify distinct subgroups of treatment responders and nonresponders to aid in the development of tailored smoking-cessation interventions for long-term maintenance using signal detection analysis (SDA). METHODS The secondary analyses (n = 301) are based on data obtained in our randomized clinical trial designed to assess the efficacy of extended cognitive behavior therapy for cigarette smoking cessation. Model 1 included only pretreatment factors, demographic characteristics, and treatment assignment. Model 2 included all Model 1 variables, as well as clinical data measured during treatment. RESULTS SDA was successfully able to identify smokers with varying probabilities of maintaining abstinence from end-of-treatment to 52-week follow-up; however, the inclusion of clinical data obtained over the course of treatment in Model 2 yielded very different partitioning parameters. CONCLUSIONS The findings from this study may enable researchers to target underlying factors that may interact to promote maintenance of long-term smoking behavior change.

Abstract
Cigarette smoking is the leading cause of preventable deaths worldwide. Long-term smoking cessation can drastically reduce people's risk for developing smoking-related disease. The research literature points to a need for clearer operationalization and differentiation between smoking cessation and relapse prevention interventions and outcomes. That said, extensive meta-analyses and research studies have indicated that there are various efficacious smoking interventions that can both support smoking cessation and relapse prevention efforts. Specifically, behavioral treatments, relapse prevention psychotherapy, pharmacologic interventions, motivational enhancement, smoking reduction to quit, brief advice, alternative intervention modes (telephone, Internet, computer), self-help, and tailored treatments can help prepare smokers for longer-term abstinence. Although these methods vary on reach, they are relatively efficacious, particularly in combined formats.

Abstract
BACKGROUND There is limited population-based evidence on long-term smoking relapse rates after 1 year of abstinence. We estimate the incidence of relapse and evaluate demographic, health, socioeconomic characteristics, and episodic events associated with an increased probability of relapse. METHODS Smoking relapse is studied using a subsample of individuals in the annual British Household Panel Survey, between 1991 and 2006, who reported not being a smoker for at least 1 year (two consecutive surveys) after previously reporting smoking (n = 1,578). A random-effects panel logit regression was used to examine the association between smoking relapse and length of abstinence, demographic, socioeconomic, and health variables. RESULTS Data were available on individuals for a mean of 5.2 years after the initial 1-year smoking abstinence. We estimated that 37.1% (34.0%-40.5%; 95% CI) of the sample would relapse within 10 years. Increased length of abstinence, increased age, being married, being educated to degree level, and a high frequency of General Practitioner (GP) visits were significantly associated with a lower risk of relapse. Conversely, higher relapse rates were significantly associated with mental health problems and having a partner who started smoking. CONCLUSIONS A significant proportion of smokers relapse after more than 1 year of abstinence. This study sheds light on factors associated with long-term relapse. This can form the basis for designing public health interventions to prolong abstinence and targeting interventions at former smokers at the highest risk of relapse.

Abstract
Background UK NHS Stop Smoking Services provide cost effective smoking cessation interventions but, as yet, there has been no assessment of their provision of relapse prevention interventions. Methods Electronic questionnaire survey of 185 UK Stop Smoking Services Managers. Results Ninety six Stop Smoking Service managers returned completed questionnaires (52% response rate). Of these, 58.3% (n = 56) ran NHS Stop Smoking Services which provided relapse prevention interventions for clients with the most commonly provided interventions being behavioural support: telephone (77%), group (73%), and individual (54%). Just under half (48%, n = 27) offered nicotine replacement therapy (NRT), 21.4% (n = 12) bupropion; 19.6% (n = 11) varenicline. Over 80% of those providing relapse prevention interventions do so for over six months. Nearly two thirds of all respondents thought it was likely that they would either continue to provide or commence provision of relapse prevention interventions in their services. Of the remaining respondents, 66.7% (n = 22) believed that the government focus on four-week quit rates, and 42.9% (14 services) believed that inadequate funding for provision of relapse prevention interventions, were major barriers to introducing these interventions into routine care. Conclusions Just over half of UK managers of NHS Stop Smoking Services who responded to the questionnaire reported that, in their services, relapse prevention interventions were currently provided for clients, despite, at that time, there being a weak evidence base for their effectiveness. The most commonly provided relapse prevention interventions were those for which there was least evidence. If these interventions are found to be effective, barriers would need to be removed before they would become part of routine care.

Abstract
Smoking is the most preventable cause of ill health, and is associated with many long-term conditions. Around 24% of all deaths in Scotland in 2004 were attributed to smoking (NHS Health Scotland and ASH Scotland, 2007). This article provides background information on the health effects of smoking, and discusses issues around stop smoking support, highlighting some implications for community nurses who work with clients who want to stop smoking.

Abstract
BACKGROUND Identifying predictors of smoking relapse helps to elucidate the challenges of long-term smoking cessation and provides direction for improved treatment development. METHODS In this post hoc data analysis, we examined predictors of relapse from end-of-treatment (week 13) through 1-year follow-up (week 52) for treatment-responding participants who achieved the primary efficacy endpoint of 4-week continuous abstinence (weeks 9-12), during two phase III varenicline trials. RESULTS Of 626 smokers classified as treatment responders for all treatment groups across both trials, 301 (48%) relapsed during follow-up (weeks 13-52). The odds of relapsing were almost 5 times greater (odds ratio [OR]=4.92, 95% confidence interval [CI]: 2.77-8.97; p<.001) for treatment responders who did not initiate continuous abstinence until the final 4 weeks of the treatment period compared with those who initiated continuous abstinence by their quit date. Participants who reported >30 days of abstinence during the year prior to study entry were significantly more likely to relapse than those who reported 0 days of abstinence (OR=2.38, 95% CI: 1.17-5.04; p=.013). CONCLUSION Results of these analyses suggest that the ability to quit smoking on the initial quit date and maintain abstinence throughout the treatment period is a good prognostic indicator for long-term abstinence. The relationship between post-treatment relapse and longer pretreatment periods of abstinence is counterintuitive, yet not without precedence in the literature.

Abstract
Tobacco use has been clearly demonstrated to have negative health consequences. Smoking cigarettes is the predominant method of tobacco use. The tar contained within cigarettes and other similar products is also harmful. Other tarless tobacco containing products do exist but carry no significantly decreased risk. While nicotine is considered to be principally responsible for tobacco addiction, other chemicals in the cigarette smoke including acetaldehyde may contribute to the addictive properties of tobacco products. The adverse health consequences of tobacco use have been well documented. Studies have shown that a combined behavioral and pharmacological approach is more effective in smoking cessation than either approach alone. Pharmacotherapy can achieve 50% reduction in smoking. With pharmacotherapy the estimated 6-month abstinence rate is about 20%, whereas it is about 10% without pharmacotherapy. The first-line of drugs for smoking cessation are varenicline, bupropion sustained release, and nicotine replacement drugs, which are approved for use in adults. Data are insufficient to recommend their use in adolescents. This article reviews the use of pharmacological agents used for smoking cessation. A brief overview of epidemiology, chemistry, and adverse health effects of smoking is provided.

Abstract
OBJECTIVE Though the prevalence of COPD is related to the definition, even with this proviso COPD remains under-diagnosed. Screening can detect many new COPD cases, but its effects on smoking cessation remain unknown. DESIGN To evaluate symptoms in "healthy" cigarette smokers, to screen new COPD cases using international and national guidelines, and to assess the success of a smoking cessation. SUBJECTS Healthy asymptomatic smokers with a >20 pack-years smoking history were recruited. The first visit included a standardized personal interview, Fagerstom nicotine dependence test (FNDT) and individualized smoking counselling by Motivational Interviewing. At the follow-up visit two years later, the same analyses were repeated and smoking status assessed. To avoid bias in the counselling attributable to spirometry, the test was evaluated at the two-year follow-up assessment. RESULTS Almost all, 93.2%, of 584 participants attended the second visit. Spirometry revealed COPD by GOLD criteria in 11.0% and by national guidelines in 15.3%, mid-expiratory flow (MEF50) had significantly declined in 19.5%, chronic cough or sputum production was detected in 62% of the subjects. After two years, 23.3% had succeeded in giving up smoking. There were four predictors of successful quitting, i.e. positive attitude to the intervention, pharmacotherapy, older age, and higher BMI, whereas other factors such as cough, obstruction, gender, pack-years, or nicotine dependence showed no association with ability to achieve successful cessation. CONCLUSION Significant numbers of "healthy" smokers experience symptoms, according to detailed questionnaires, and have COPD. Motivation is the most significant factor in determining the chance of stopping smoking.

Abstract
INTRODUCTION Postpartum relapse rates are high among women who spontaneously quit smoking during pregnancy. This randomized clinical trial tested a Motivation and Problem-Solving (MAPS) treatment for reducing postpartum relapse among diverse low-income women who quit smoking during pregnancy (N = 251; 32% Black, 30% Latino, and 36% White; 55% <$30,000/year household income). METHODS Pregnant women were randomly assigned to MAPS/MAPS+ or Usual Care (UC). Continuation ratio logit models were used to examine differences in biochemically confirmed continuous abstinence at Weeks 8 and 26 postpartum by treatment group and moderators of the treatment effect. Analyses controlled for age, race/ethnicity, partner status, education, smoking rate, and the number of smokers in the participant's environment. RESULTS MAPS/MAPS+ was more efficacious than UC in the prevention of postpartum relapse (p = .05). An interaction between treatment and the number of cigarettes smoked per day before quitting approached significance (p = .09), suggesting that the MAPS/MAPS+ treatment effect was stronger among women who smoked more cigarettes per day. DISCUSSION MAPS, a holistic and dynamic approach to changing behavior using a combined motivational enhancement and social cognitive approach, is a promising intervention for postpartum smoking relapse prevention among low-income women, which may have particular relevance for women with higher prequit smoking rates.

Abstract
Although the prevalence of tobacco use is decreasing in many high-income countries, it is increasing in many low- and middle-income countries. The health and economic burden of increasing tobacco use and dependence is predictable and will have devastating effects in countries with limited resources, particularly for vulnerable populations such as pregnant women. We sought to review effective tobacco prevention and intervention strategies for decreasing tobacco use and secondhand smoke exposure before and during pregnancy in high-, middle-, and low-income countries. We reviewed several types of interventions, including population-level efforts (increasing tobacco prices, implementing tobacco control policies), community interventions, clinical interventions, and pharmacological treatments. A second purpose of this report is to present findings of an international expert working group that was convened to review the evidence and to establish research priorities in the following areas: (a) preventing the uptake and reducing tobacco use among girls and women of reproductive age; and (b) reducing tobacco use and secondhand smoke exposure among pregnant women. The working group considered the evidence on existing interventions in terms of burden of disease, intervention impact, intervention costs, feasibility of integration into existing services, uniqueness of the contribution, and overall feasibility. Finally, we present the working group's recommendations for intervention research priorities.

Abstract
The field of pharmacologic addiction treatment is expanding rapidly. While there are currently several FDA-approved medications for nicotine, alcohol, and opiate dependence, research into novel pharmacological approaches for these and additional substances is legion. Each drug of abuse, while sharing a common final neural pathway of increasing dopaminergic tone, has unique and individual characteristics that are important in developing improved and varied treatments. In this chapter, we discuss such research and present the neurobiological underpinnings of these explorations. In general, addiction treatment is focused on four areas: (1) reducing withdrawal discomfort, (2) diminishing cravings, (3) blocking rewarding effects of the drug, and (4) treating comorbidities, such as depression or ADHD. We present current ideas in pharmacologic research for nicotine, alcohol, cannabis, stimulants, and opiates.

Abstract
Although tobacco smoking, which has been linked to depression, is a major public health problem, little is known about the neurobiological factors that confer vulnerability to smoking in youngsters and the effects of adolescent smoking on the course of depression. This study examined whether hypothalamic-pituitary-adrenal (HPA) activity and stressful life experiences are related to smoking behavior in depressed and non-depressed adolescents, and whether smoking predicts a worsening course of depression. Smoking history and stressful experiences were assessed in 151 adolescents (48 with no personal or family history of psychiatric disorder, 48 with no psychiatric history, but at high risk for depression by virtue of parental depression, and 55 with current major depressive disorder). Evening salivary cortisol and nocturnal urinary-free cortisol were measured for three consecutive evenings. The participants were then followed at regular intervals for up to 5 years to assess smoking history, clinical course of depression and stressful experiences during the follow-up period. Increased evening/night-time cortisol levels were associated with both initiation and persistence of smoking during follow-up. Stressful life experiences further increased the risk for smoking in depressed as well as non-depressed youth. Smoking was also associated with a higher frequency of depressive episodes during follow-up. A model that included stressful experiences and cortisol levels reduced the contribution of smoking per se to depression. High evening/night-time cortisol level appears to be a vulnerability marker for smoking in adolescents, with stressful experiences further increasing the risk for smoking in vulnerable youth. High evening/night-time cortisol levels and stressful experiences accounted, at least partially, for the association between depressive illness and smoking behavior.
