Few pharmacological therapies have been shown to increase abstinence rates among spit tobacco (ST) users. Bupropion has been shown to be effective in increasing abstinence rates among smokers but has not been studied in ST users. Sixty-eight adult (aged > or = 18 years old) regular users of ST who were motivated to stop using ST were enrolled in a randomized, double-blind, placebo-controlled pilot study of bupropion sustained release (SR) or placebo for 12 weeks. The primary endpoint was 1-week, biochemically confirmed point-prevalence tobacco abstinence rate at the end of treatment (week 12). Nicotine withdrawal symptoms and weight change were assessed. At the end of 12 weeks of therapy, the point-prevalence tobacco abstinence rate was 44% in the bupropion group and 26% in the placebo group (p = 0.064). At 24 weeks following initiation of medication, the point-prevalence abstinence rate was 29% for both groups. After 7 weeks of medication, subjects on bupropion reported significantly less (p< or = 0.034) nicotine withdrawal than placebo. The mean weight change from baseline to end of treatment was +0.7 +/- 1.9 kg for bupropion and +4.4 +/- 2.4 kg for placebo (p = 0.03). The 6-month weight change for continuously abstinent subjects was 3.4 +/- 3.6 kg in the bupropion group and 6.2 +/- 5.0 kg in the placebo group (p = 0.49). Bupropion may increase abstinence rates in ST users and appears to attenuate weight gain during ST abstinence. Larger randomized, controlled trials of bupropion for ST users are needed. Individuals with schizophrenia smoke at higher rates (58%-88%) than the general population (approximately 22%), and have difficulty quitting. We determined whether the combination of sustained-release (SR) bupropion (BUP) with the transdermal nicotine patch (TNP) was well-tolerated and superior to placebo (PLO)+TNP for smoking cessation in schizophrenia.
                A 10-week, double-blind, placebo-controlled trial of BUP (300 mg/day) in combination with TNP (21 mg/24h) for 58 outpatient smokers with schizophrenia was conducted. Primary outcome measures were continuous smoking abstinence in the last 4 weeks of the trial (Days 43-70) and 7-day point prevalence abstinence at 6 months post-target quit date (TQD) (week 26).
                Smokers assigned to the BUP+TNP group (n = 29) were more likely to achieve continuous smoking abstinence (8/29, 27.6%) than the PLO+TNP group (n = 29, 1/29, 3.4%) [Fisher's Exact Test, p < .05]; at 6-months post-TQD, 4/29 (13.8%) versus 0/29 (0.0%) achieved 7-day point prevalence smoking abstinence (p = .11). Neither bupropion SR nor smoking abstinence significantly altered the positive or negative symptoms of schizophrenia. The combination was well-tolerated in smokers with schizophrenia.
                Combination therapy with bupropion SR+TNP versus placebo+TNP is well-tolerated and significantly improved short-term smoking abstinence in smokers with schizophrenia. Previous published studies assessed the efficacy of bupropion in smoking cessation only in North American populations of smokers. Results of therapeutic drug trials are not always directly applicable in other populations.
                To confirm the efficacy of bupropion in smoking cessation in European smokers.
                A multi-centre, randomized, double-blind placebo-controlled trial.
                Seventy-four smoking cessation out-patient clinics in France.
                The study included 509 smokers motivated to quit smoking. Intervention Subjects were randomized to either slow-release bupropion 150 mg b.i.d. (B) or to placebo (Pl) in a 2 : 1 ratio, treated for 7 weeks, and followed-up for 26 weeks.
                Main outcome measure: 6 months' point prevalence abstinence, determined by self-report and expired air carbon monoxide measurement. Secondary outcome measures: weeks 4-7 and weeks 4-26 continuous abstinence rates, craving, withdrawal symptoms, weight and cigarette consumption in smokers unable to quit. Adverse events were recorded systematically.
                Six months' point prevalence abstinence rates were 31% and 16%[odds ratio = 2.3, confidence interval (CI) 95%: 1.4-3.7] in the B and Pl groups, respectively. Continuous abstinence rates were 41% (B) and 21% (P) with OR = 2.5 (CI 95%: 1.6-3.9) for weeks 4-7, and 25% (B) and 13% (P) with OR = 2.2 (CI 95%: 1.3-3.6) for weeks 4-26, respectively. Craving decreased significantly more with B than with Pl during treatment period, but there was no difference for total withdrawal symptoms score. Abstinent subjects gained significantly less weight at week 7 with B than with Pl. Low level of nicotine dependence, high motivation, absence of smoking-related disease, long duration of previous quit attempts, male gender, low level of current alcohol problems and living as a couple were predictive of successful cessation. With the exception of marital status, no interaction was observed between any of these predictive factors and the efficacy of bupropion. More of those who continued smoking in the B group than the P group reduced their consumption by at least 50%.
                Sustained-release bupropion is efficacious as an aid to smoking cessation in European smokers. No outcome predictors were identified that might indicate that certain subgroups of smokers would benefit more than others from treatment with bupropion. The objective of this study was to examine whether there is a benefit of adding bupropion SR to high-dose combination nicotine replacement therapy (NRT) and weekly group cognitive behavioral therapy (CBT) for smoking reduction or cessation in schizophrenia. Fifty-one adult smokers with schizophrenia were randomly assigned to a 12-week trial of bupropion SR 300 mg/d or placebo added to transdermal nicotine patch, nicotine polacrilex gum, and CBT. The treatment goal was smoking cessation. The primary outcome measure was biochemically confirmed 7-day point-prevalence of 50% to 100% smoking reduction at week 12. Secondary outcomes were biochemically confirmed tobacco abstinence and change from baseline in expired air carbon monoxide (CO) and psychiatric symptoms. Subjects on bupropion + NRT had a greater rate of 50% to 100% smoking reduction at weeks 12 (60% vs. 31%; P = 0.036) and 24, a lower expired air CO in the treatment and follow-up periods, (F = 13.8; P < 0.001) and a greater continuous abstinence rate at week 8, before NRT taper, (52% vs. 19%; P = 0.014). However, relapse rates in subjects on bupropion + dual NRT were 31% during NRT taper (weeks 8-12) and 77% at the 12-month follow-up. Abstinence rates did not differ by treatment group at weeks 12 (36% vs. 19%), 24 (20% vs. 8%), or 52 (12% vs. 8%). Because abstinence rates were high during treatment with combination pharmacotherapy and relapse rates were very high during taper and after discontinuation of treatment, study of longer term treatment with combination pharmacotherapy and CBT for sustained abstinence is warranted in those who attain initial abstinence with this intervention. Naltrexone (NTX), by its pharmacological action in the mesolimbic pathways, should decrease reinforcement from nicotine as well as from alcohol. By means of this mechanism, NTX could result in temporary increases in smoking followed by decreased smoking rates among alcoholics not motivated to quit smoking. The change from pretreatment in smoking rates of 73 recently abstinent alcoholics in a 12-week clinical trial of NTX vs. placebo during alcoholism treatment was compared during 8 of the 12 weeks. Only smokers compliant with NTX were included in the analyses. NTX was associated with decreased smoking at every time point, but the effect was significant at only one time point. When alcohol relapsers were excluded, NTX patients showed decreased smoking at every time point, but the effect was significant at only two time points, a reduction of about five cigarettes per day. When smoking stage of change was included in the analyses, NTX showed no significant main or interaction effects on smoking rate. Precontemplators showed significantly less change in smoking rate than all other patients at the first and last four time points. Therefore, NTX alone currently does not show promise for promoting smoking reduction among recently abstinent alcoholics who have not sought or been given smoking cessation treatment. Further research is needed on possible effects with smokers motivated to quit smoking and on other methods of promoting smoking cessation among alcoholics. Cognitive behavior therapy (CBT) constitutes the basis of smoking cessation programs. Quitting rates are usually increased by the concomitant use of CBT and pharmacotherapy. There are studies showing the efficacy of bupropion and nortriptyline compared to placebo, but there is just one published comparison between these drugs, unfortunately with low power to detect significant differences. This study was designed to compare the efficacy of bupropion, nortriptyline and placebo in a group of smokers who also received intensive counseling therapy. We conducted a double blind, double-dummy, placebo-controlled trial for smoking cessation that lasted 9 weeks. Patients were randomized to receive nortriptyline 75 mg/day (52 subjects), bupropion 300 mg/day (53 subjects) or placebo (51 subjects). All smokers also received the same intensive cognitive behavior therapy. The target day for quitting smoking was usually day 10. Intensive counseling was provided at baseline, weekly during treatment, and at 10, 13, 16, 20 and 26 weeks. Abstinence was defined as continuous when the subject was not smoking since the target-quitting day (self-report) and had an expired carbon monoxide concentration of 10 ppm or less.
                The sustained abstinence rates at 6 months were 21.6% in the placebo group, 30.8% in the nortriptyline group (p = 0.40), and 41.5% in the bupropion group (p = 0.05). The odds ratio was not statistically different for smokers using nortriptyline or bupropion (OR 1.60; 95% CI 0.66-3.86; p = 0.35). The most common adverse events were dry mouth and drowsiness in the nortriptyline group and dry mouth and insomnia in the bupropion group.
                Treatment with CBT + bupropion resulted in a better 6-month rate of smoking cessation compared to CBT+nortriptyline or CBT + placebo. Abstinence rate in the nortriptyline group was not statistically different from patients in the bupropion or placebo group. To test the hypothesis that among adolescent smokers hospitalised for psychiatric and substance use disorders, motivational interviewing (MI) would lead to more and longer quit attempts, reduced smoking, and more abstinence from smoking over a 12 month follow up.
                Randomised control trial of MI versus brief advice (BA) for smoking cessation, with pre- and post-intervention assessment of self efficacy and intentions to change, and smoking outcome variables assessed at one, three, six, nine, and 12 month follow ups.
                A private, university affiliated psychiatric hospital in Providence, Rhode Island, USA.
                Consecutive sample (n = 191) of 13-17 year olds, admitted for psychiatric hospitalisation, who smoked at least one cigarette per week for the past four weeks, had access to a telephone, and did not meet DSM-IV criteria for current psychotic disorder.
                MI versus BA. MI consisted of two, 45 minute individual sessions, while BA consisted of 5-10 minutes of advice and information on how to quit smoking. Eligible participants in both conditions were offered an eight week regimen of transdermal nicotine patch upon hospital discharge.
                Point prevalence abstinence, quit attempts, changes in smoking rate and longest quit attempt. Proximal outcomes included intent to change smoking behaviour (upon hospital discharge), and self efficacy for smoking cessation.
                MI did not lead to better smoking outcomes compared to BA. MI was more effective than BA for increasing self efficacy regarding ability to quit smoking. A significant interaction of treatment with baseline intention to quit smoking was also found. MI was more effective than BA for adolescents with little or no intention to change their smoking, but was actually less effective for adolescents with pre-existing intention to cut down or quit smoking. However, the effects on these variables were relatively modest and only moderately related to outcome. Adolescents with comorbid substance use disorders smoked more during follow up while those with anxiety disorders smoked less and were more likely to be abstinent.
                The positive effect of MI on self efficacy for quitting and the increase in intention to change in those with initially low levels of intentions suggest the benefits of such an intervention. However, the effects on these variables were relatively modest and only moderately related to outcome. The lack of overall effect of MI on smoking cessation outcomes suggests the need to further enhance and intensify this type of treatment approach for adolescent smokers with psychiatric comorbidity. There are 1.1 billion smokers worldwide. Traditional smoking cessation methods, such as nicotine replacement therapy and smoking cessation groups, yield between 14% and 27% abstinence rates at 6 months. Evidence-based Internet interventions with comparable abstinence rates could be a powerful global tool to reduce tobacco-related morbidity and mortality.
                We report a randomized control trial in which 500 Spanish-speaking and 500 English-speaking adult Internet users, smoking at least 5 cigarettes/day and intending to quit in the next month, were recruited online from 68 countries. Consenting participants who completed baseline measures, logged cigarettes smoked on 3 days within a week, and set a quit date were randomized to four conditions. Each condition added new elements: Condition 1 was the "Guía Para Dejar de Fumar," a static National Cancer Institute evidence-based stop smoking guide; Condition 2 consisted of Condition 1 plus E-mail reminders to return to the site; Condition 3 consisted of Condition 2 plus mood management lessons; and Condition 4 consisted of Condition 3 plus a "virtual group" (an asynchronous bulletin board). Main outcome measures were 7-day point prevalence abstinence at 1, 3, 6, and 12 months after initial quit date.
                There were no significant differences among the four conditions. The overall 12-month 7-day abstinence rates were 20.2% for Spanish speakers and 21.0% for English speakers when those with missing data were assumed to be smoking.
                Internet smoking cessation interventions with such abstinence rates provided globally in additional languages could contribute substantially to tobacco control efforts. Despite extremely high rates of smoking among individuals with psychotic disorders and the associated financial and health costs, few studies have investigated the efficacy of smoking cessation interventions among this group. The purpose of this study was to compare an integrated psychological and nicotine replacement therapy intervention for people with a psychotic disorder with routine care alone.
                The authors recruited 298 regular smokers with a psychotic disorder residing in the community and randomly assigned them to a routine care comparison condition (N=151) or an eight-session, individually administered smoking cessation intervention (N=147), which consisted of nicotine replacement therapy, motivational interviewing, and cognitive behavior therapy. Outcome variables included continuous and point-prevalence abstinence rates, smoking reduction status, and changes in symptoms and functioning.
                While there were no overall differences between the treatment group and comparison group in abstinence rates, a significantly higher proportion of smokers who completed all treatment sessions stopped smoking at each of the follow-up occasions (point-prevalence rates: 3 months, 30.0% versus 6.0%; 6 months, 18.6% versus 4.0%; and 12 months, 18.6% versus 6.6%). Smokers who completed all treatment sessions were also more likely to have achieved continuous abstinence at 3 months (21.4% versus 4.0%). There was a strong dose-response relationship between treatment session attendance and smoking reduction status, with one-half of those who completed the intervention program achieving a 50% or greater reduction in daily cigarette consumption across the follow-ups, relative to less than one-fifth of the comparison subjects. There was no evidence of any associated deterioration in symptoms or functioning.
                These findings demonstrate the utility of a nicotine replacement therapy plus motivational interviewing/cognitive behavior therapy smoking cessation intervention among individuals with a psychotic disorder. Further development of more efficacious interventions is required for those who do not respond to existing interventions. To examine the individual effects of supervised and intensive exercise as well as the combined effects of exercise and nicotine replacement therapy (NRT) on (a) smoking cessation and reduction rates and (b) psychological and physiological processes during withdrawal.
                One-hundred and forty-two inactive female smokers were randomised into the following four groups: exercise+nicotine patch; exercise+no nicotine patch; cognitive behavior therapy (CBT)+nicotine patch and CBT+no nicotine patch. Smoking abstinence (verified by saliva cotinine and expired carbon monoxide), cessation self-efficacy, and physical fitness and body weight were assessed at baseline (week 1), quit date (week 6), program termination (week 12), and 3- and 12-month follow-up.
                There were significant differences in a 7-day point prevalence but not continuous abstinence rates between treatment groups across targeted end points. Consistently higher cessation rates were seen when NRT was added to both treatment programs. Compared with CBT participants, exercise participants had significantly increased functional exercise capacity and had gained significantly less weight during program end points but these differences did not hold at a 12-month follow-up. Compared with exercise participants, CBT participants felt greater cessation efficacy and reported greater knowledge, coping and support resources across all end points.
                Exercise combined with NRT facilitates smoking cessation, improves functional exercise capacity, and delays weight gain in women smokers. We recommend that physicians and health care professionals recommend exercise and NRT together for highly motivated women interested in quitting smoking. Randomized efficacy clinical trials conducted in research settings may not accurately reflect the benefits of tobacco dependence treatments when used in real-world clinical settings. Effectiveness trials (eg, in primary care settings) are needed to estimate the benefits of cessation treatments in real-world use.
                A total of 1346 primary care patients attending routine appointments were recruited by medical assistants in 12 primary care clinics. Patients were randomly assigned to 5 active pharmacotherapies: 3 monotherapies (nicotine patch, nicotine lozenge, and bupropion hydrochloride sustained release [SR]) and 2 combination therapies (patch + lozenge and bupropion SR + lozenge). Patients were referred to a telephone quit line for cessation counseling. Primary outcomes included 7-day point prevalence abstinence at 1 week, 8 weeks, and 6 months after quitting and number of days to relapse.
                Among 7128 eligible smokers (> or =10 cigarettes per day) attending routine primary care appointments, 1346 (18.9%) were enrolled in the study. Six-month abstinence rates for the 5 active pharmacotherapies were the following: bupropion SR, 16.8%; lozenge, 19.9%; patch, 17.7%; patch + lozenge, 26.9%; and bupropion SR + lozenge, 29.9%. Bupropion SR + lozenge was superior to all of the monotherapies (odds ratio, 0.46-0.56); patch + lozenge was superior to patch and bupropion monotherapies (odds ratio, 0.56 and 0.54, respectively).
                One in 5 smokers attending a routine primary care appointment was willing to make a serious quit attempt that included evidence-based counseling and medication. In this comparative effectiveness study of 5 tobacco dependence treatments, combination pharmacotherapy significantly increased abstinence compared with monotherapies. Provision of free cessation medications plus quit line counseling arranged in the primary care setting holds promise for assisting large numbers of smokers to quit. Trial Registration clinicaltrials.gov Identifier: NCT00296647. Tobacco dependence treatments achieve abstinence rates of 25-30% at 1 year. Low rates may reflect failure to conceptualize tobacco dependence as a chronic disorder. The aims of the present study were to determine the efficacy of extended cognitive behavioral and pharmacological interventions in smokers > or = 50 years of age, and to determine if gender differences in efficacy existed.
                Open randomized clinical trial.
                A free-standing, smoking treatment research clinic.
                A total of 402 smokers of > or = 10 cigarettes per day, all 50 years of age or older.
                Participants completed a 12-week treatment that included group counseling, nicotine replacement therapy (NRT) and bupropion. Participants, independent of smoking status, were then assigned randomly to follow-up conditions: (i) standard treatment (ST; no further treatment); (ii) extended NRT (E-NRT; 40 weeks of nicotine gum availability); (iii) extended cognitive behavioral therapy (E-CBT; 11 cognitive behavioral sessions over a 40-week period); or (iv) E-CBT plus E-NRT (E-combined; 11 cognitive behavioral sessions plus 40 weeks nicotine gum availability).
                Primary outcome variable was 7-day point prevalence cigarette abstinence verified biochemically at weeks 24, 52, 64 and 104.
                The most clinically important findings were significant main effects for treatment condition, time and the treatment x time interaction. The E-CBT condition produced high cigarette abstinence rates that were maintained throughout the 2-year study period [(week 24 (58%), 52 (55%), 64 (55%) and 104 (55%)], and was significantly more effective than E-NRT and ST across that period. No other treatment condition was significantly different to ST. No effects for gender were found.
                Extended cognitive behavioral treatments can produce high and stable cigarette abstinence rates for both men and women. NRT does not add to the efficacy of extended CBT, and may hamper its efficacy. Research is needed to determine if these results can be replicated in a sample with a greater range of ages, and improved upon with the addition of medications other than NRT. To determine the safety and efficacy of the nicotine patch and gum for adolescents who want to quit smoking.
                Double-blind, double-dummy, randomized, 3-arm trial with a nicotine patch (21 mg), nicotine gum (2 and 4 mg), or a placebo patch and gum; all participants received cognitive-behavioral group therapy.
                Inner-city, outpatient clinic on the East Coast. Subjects. Thirteen- to 17-year-old adolescents who smoked > or =10 cigarettes per day (CPD), scored > or =5 on the Fagerstrom Test of Nicotine Dependence, and were motivated to quit smoking. Intervention. Twelve weeks of nicotine patch or gum therapy with cognitive-behavioral therapy, with a follow-up visit at 6 months (3 months after the end of treatment).
                Safety assessed on the basis of adverse event reports for all 3 groups, prolonged abstinence, assessed through self-report and verified with exhaled carbon monoxide (CO) levels of < or =6 ppm, in intent-to-treat analyses, and smoking reduction (CPD and thiocyanate concentrations) among trial completers.
                A total of 120 participants were randomized (72% white, 70% female; age: 15.2 +/- 1.33 years; smoking: 18.8 +/- 8.56 CPD; Fagerstrom Test of Nicotine Dependence score: 7.04 +/- 1.29) from 1999 to 2003. Participants started smoking at 11.2 +/- 1.98 years of age and had been smoking daily for 2.66 +/- 1.56 years; 75% had at least 1 current psychiatric diagnosis. Mean compliance across groups was higher for the patch (mean: 78.4-82.8%) than for the gum (mean: 38.5-50.7%). Both the patch and gum were well tolerated, and adverse events were similar to those reported in adult trials. Changes in mean saliva cotinine concentrations throughout treatment were not statistically significant. Intent-to-treat analyses of all randomized participants showed CO-confirmed prolonged abstinence rates of 18% for the active-patch group, 6.5% for the active-gum group, and 2.5% for the placebo group; the difference between the active-patch and placebo arms was statistically significant. There was no significant effect of patch versus gum or gum versus placebo on cessation outcomes. Abstinence rates at the 3-month follow-up assessment were sustained but were not significantly associated with treatment group. Mean smoking rates, but not CO or thiocyanate concentrations, decreased significantly in all 3 arms but not as a function of treatment group.
                Nicotine patch therapy combined with cognitive-behavioral intervention was effective, compared with placebo, for treatment of tobacco dependence among adolescent smokers. Decreases in the numbers of cigarettes smoked appeared to be offset by compensatory smoking. Additional study of nicotine gum, with enhanced instructional support, is needed to assess its efficacy among adolescent smokers. To investigate the safety and efficacy of bupropion sustained release (bupropion SR) in promoting abstinence from smoking in subjects with cardiovascular disease (CVD).
                Six hundred twenty-nine subjects with CVD who smoked >/=10 cigarettes/day were randomised in a double-blind, multicentre study to receive bupropion SR (150 mg twice daily) or placebo for 7 weeks, with a follow-up of 52 weeks. Primary efficacy endpoint: continuous abstinence from smoking from weeks 4 to 7. Secondary endpoints: continuous abstinence (weeks 4-12, 4-26 and 4-52) and weekly point prevalence abstinence. All participants received brief motivational support. Safety was evaluated throughout the study.
                Continuous smoking abstinence rates from weeks 4 to 7 were significantly higher in subjects receiving bupropion SR compared with placebo (43 vs. 19%, odds ratio [OR]=3.27, 95% confidence interval [CI] 2.24-4.84; P<0.001). Continuous abstinence rates from weeks 4 to 26 and 4 to 52 continued to be more than double for bupropion SR compared with placebo (27 vs. 11%; 22 vs. 9%, P<0.001). Weekly point prevalence abstinence was significantly higher for participants who received bupropion SR compared with placebo at weeks 3, 7, 26 and 52 (P<0.001). In both groups, there were no clinically significant changes in blood pressure and heart rate throughout the treatment phase. Overall, 6% of the participants (n=36) discontinued study medication due to an adverse event (bupropion SR, n=17; placebo, n=19).
                After 7 weeks of bupropion SR treatment, more than twice as many smokers with CVD had quit smoking at 1 year compared with placebo. The safety profile of bupropion SR was similar to that previously observed in general smoking populations. Little direct evidence exists on the relative efficacies of different smoking cessation pharmacotherapies, yet such evidence is needed to make informed decisions about their clinical use.
                To assess the relative efficacies of 5 smoking cessation pharmacotherapy interventions using placebo-controlled, head-to-head comparisons.
                A randomized, double-blind, placebo-controlled clinical trial.
                Two urban research sites.
                One thousand five hundred four adults who smoked at least 10 cigarettes per day during the past 6 months and reported being motivated to quit smoking. Participants were excluded if they reported using any form of tobacco other than cigarettes; current use of bupropion; having a current psychosis or schizophrenia diagnosis; or having medical contraindications for any of the study medications.
                Participants were randomized to 1 of 6 treatment conditions: nicotine lozenge, nicotine patch, sustained-release bupropion, nicotine patch plus nicotine lozenge, bupropion plus nicotine lozenge, or placebo. In addition, all participants received 6 individual counseling sessions.
                Biochemically confirmed 7-day point-prevalence abstinence assessed at 1 week after the quit date (postquit), end of treatment (8 weeks postquit), and 6 months postquit. Other outcomes were initial cessation, number of days to lapse, number of days to relapse, and latency to relapse after the first lapse.
                All pharmacotherapies differed from placebo when examined without protection for multiple comparisons (odds ratios, 1.63-2.34). With such protection, only the nicotine patch plus nicotine lozenge (odds ratio, 2.34, P < .001) produced significantly higher abstinence rates at 6-month postquit than did placebo.
                While the nicotine lozenge, bupropion, and bupropion plus lozenge produced effects that were comparable with those reported in previous research, the nicotine patch plus lozenge produced the greatest benefit relative to placebo for smoking cessation. In a unique approach to utilizing an existing intervention, "opportunistic" and targeted school-based strategies were used to enroll 446 adults into a tailored preventive health program featuring a health screening and smoking-cessation intervention. Implemented through a public school district serving a multi-ethnic low-to-middle income urban community, subjects in this randomized trial were interviewed at enrollment and at three-, six-, and 12-month follow-up, and rescreened at 12 months, to assess changes in smoking-related knowledge, attitudes, and practices. Using conservative assumptions, self-reported ever-quit rates and continuous abstinence rates of 57.5% and 2.6%, respectively, were achieved across groups; point-prevalence abstinence rates were 13.2%, 12.9%, and 10.3% at three, six, and 12 months. The study examines issues relevant to smoking status and stages of change in this population. The role of the school in increasing access to needed health programming in underserved communities is explored. Nicotine replacement therapy (NRT) is an established aid in stopping smoking, while the role of antidepressants remains uncertain. Antidepressants added to NRT might improve abstinence rates. Our aim was to determine the efficacy of nicotine inhaler and fluoxetine vs. nicotine inhaler and placebo in attempts to quit smoking.
                A randomized, double-blind, placebo-controlled trial.
                A smoker's cessation clinic.
                One hundred volunteers smoking 10 cigarettes/day or more.
                Subjects were instructed to start taking a daily dose of 10 mg of fluoxetine or placebo 16 days before stopping smoking, then 20 mg 10 days before quitting, continuing for up to at least 3 months. Subjects were instructed to use 6-12 units per day of nicotine inhalers after stopping smoking for up to 6 months.
                Continuous abstinence rates recorded at various time points up to 12 months from the quit date.
                The sustained abstinence rate for the inhaler-fluoxetine group was 54%, 40%, 29% and 21% after 1.5, 3, 6 and 12 months, respectively, compared to 48%, 40%, 32% and 23% for the inhaler-placebo group. The differences were not significant at any time point. Abstinence up to 3 months was more likely in older smokers, those with a lower Beck Depression Inventory Score (BDI), lower Fagerström Test of Nicotine Dependence (FTND) score and no history of alcoholism. Fluoxetine appeared to increase abstinence rates among high BDI smokers compared to high BDI smokers assigned placebo. Serum levels of nicotine during treatment in the inhaler-fluoxetine group were lower than in the inhaler-placebo group so that fluoxetine may have reduced inhaler use through a common site of action.
                We found no evidence that fluoxetine treatment when used as an adjunct to NRT in unselected smokers is effective, but there may be an advantage to using it in depressed smokers. Current treatment guidelines recommend that all smokers be given motivational or action-oriented counseling, as is appropriate to their readiness to quit smoking. The present study assessed the acceptability and impact of a proactively delivered, motivationally tailored phone counseling program targeted to women with elevated risk for cervical cancer. Female smokers with a recent abnormal pap exam or a colposcopy were contacted and invited to participate, regardless of their interest in quitting smoking. Participants were randomly assigned to usual care (UC) or UC plus motivationally enhanced phone counseling (MEC). The intervention was well received: 79% of eligible women enrolled (n = 275), and 90% completed at least three of four calls. Participation did not vary by baseline motivation to quit. Compared with control subjects, counseling participants were more likely to seek additional treatment services and had a higher 7-day point-prevalence abstinence rate at 6 months (20% MEC vs. 12% UC, p<.05). MEC impact was sustained at 12 months, but abstinence increased among the UC group (18% MEC vs. 20% UC, p = ns). There was no difference in repeated point-prevalence abstinence at 6 and 12 months (11% MEC vs. 10% UC, p = ns). Outcomes were similar in a subgroup of 229 women who, at baseline, were interested in quitting in the next 6 months. Sustained-release bupropion hydrochloride and nortriptyline hydrochloride have been shown to be efficacious in the treatment of cigarette smoking. It is not known whether psychological intervention increases the efficacy of these antidepressants. This study compared both drugs with placebo. It also examined the efficacy of these 2 drugs and placebo with and without psychological intervention.
                This was a 2 (medical management vs psychological intervention) x 3 (bupropion vs nortriptyline vs placebo) randomized trial. Participants were 220 cigarette smokers. Outcome measures were biologically verified abstinence from cigarettes at weeks 12, 24, 36, and 52.
                Psychological intervention produced higher 7-day point-prevalence rates of biochemically verified abstinence than did medical management alone. With the use of point-prevalence abstinence, both nortriptyline and bupropion were more efficacious than placebo. On rates of 1-year continuous abstinence, the 2 drugs did not differ from each other or from placebo. Psychological intervention did not differ from medical management alone on rates of 1-year continuous abstinence.
                Both nortriptyline and bupropion are efficacious in producing abstinence in cigarette smokers. Similarly, psychological intervention produces better abstinence rates than simple medical management. Both drugs, and psychological intervention, have limited efficacy in producing sustained abstinence. The data also suggest that combined psychological intervention and antidepressant drug treatment may not be more effective than antidepressant drug treatment alone.
Complex approaches show promise, with some persistence of abstinence (30 days point prevalence abstinence or continuous abstinence at six months), especially those incorporating elements sensitive to stage of change and using motivational enhancement and CBT.  We await results of recent trials of Not on Tobacco trials and more data is needed on sustained quitting that allows for the episodic nature of much adolescent smoking. There were few trials with evidence about pharmacological interventions (nicotine replacement and bupropion), and none demonstrated effectiveness for adolescent smokers. There is not yet sufficient evidence to recommend widespread implementation of any one model.
There continues to be a need for well-designed adequately powered randomized controlled trials of interventions for this population of smokers.
