Abstract
OBJECTIVES To explore the relationships between tobacco, social support, job satisfaction, and depression among truck drivers. METHODS Cross-sectional data were collected from 797 truck drivers in six US states. Data collected included self-reported medical history and biological samples. Modified Zung depression scale and Work Apgar scores were used to measure depression and social support. Adjusted logistic regression models were used to calculate odds ratios (OR). RESULTS 24.0% of tobacco users were in the least depressed category and 18.2% were most depressed. 22.8% of the tobacco users had the most social support compared with 27.9% of the non-users. Drivers in the two most depressed categories were significantly less likely to use tobacco (OR = 0.62, 95% confidence interval [CI] = 0.39-0.96, and OR = 0.64, 95% CI = 0.41-0.99). CONCLUSIONS Drivers with low social support or low levels of depression are more likely to be tobacco users.

Abstract
OBJECTIVES Mental health professionals (MHPs) play an important role in treating patients with nicotine addiction. However, data on MHPs' cigarette smoking habits are scarce. This survey aimed to collect such data and to examine the correlates of smoking among MHPs working in China. METHODS A cross-sectional survey was conducted in all 41 provincial, tertiary psychiatric hospitals, and MHPs from these hospitals were targeted. An anonymous questionnaire was designed to collect socio-demographic and occupational factors, and the Maslach Burnout Inventory-Human Service Survey was used to assess burnout. Data about smoking and other health behaviors were also collected. RESULTS In total, 13,614 MHPs were included in the analysis. The overall rate of current smoking was 8.6% (31.3% in males, and 1.1% in females). A substantial proportion (28.0%) of life-time smokers had abstained for more than 3 months. Those who were male (OR=37.73), older (OR=1.02), divorced or widowed (OR=1.72), working in West (OR=1.45), and Northeast China (OR=1.65), were nurses (OR=1.44), had a high income (OR=1.31), experienced burnout (OR=1.29), frequent insomnia (OR=1.39), and used alcohol (OR=2.76) were significantly more likely to be smokers, while those who had a higher level of education (OR=0.67, 0.47, and 0.43 for college, master, and doctorate degrees, respectively), and exercised regularly (OR=0.73) were significantly less likely to be smokers. CONCLUSION Although lower than that of the general population in China, smoking is still relatively high among MPHs. Efforts to lower smoking rates among MHPs in China should continue and should incorporate strategies that target burnout, sleep, alcohol use, exercise and other factors associated with smoking.

Association between smoking, and hospital readmission among inpatients with psychiatric illness at an academic inpatient psychiatric facility, 2000-2015. Addict Behav Rep 2019; 9:100181. [PMID: 31193775 PMCID: PMC6542740 DOI: 10.1016/j.abrep.2019.100181] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2018] [Revised: 04/01/2019] [Accepted: 04/03/2019] [Indexed: 01/04/2023] Open
Abstract
Introduction Smoking rates are up to 2–4 times higher among individuals with mental illness. Hospital readmissions for patients with psychiatric illness within a year of discharge are also high, and there is limited evidence of associations between smoking and these readmissions. Methods This study was a secondary data analysis using clinical data of psychiatric inpatients with initial admissions between the years 2000 and 2015. Following a descriptive analysis, logistic regression models were fitted to explore relationships between smoking and psychiatric hospital readmission within 30 days and a year of discharge. Results A total of 5439 patients with average age of 30.18 ± 15.97 were identified. Of this number, 47.0% were current smokers and 53.0% were never smokers. Within 30 days of discharge, 11% of the current smokers were readmitted compared to 9% of never smokers. The primary diagnoses with highest proportion of smokers were, opioid or substance use disorders (80.0%), schizophrenia (70.7%), alcohol dependence (68.2%), and bipolar disorders (50.8%). About 31% of current smokers were readmitted within one year of discharge compared to 26% of never smokers. Adjusted odds ratios for readmission within 1-year of discharge were, bipolar disorders (1.41, p = 0.01), schizophrenia (2.33, p < 0.001), and opioid/substance dependence (1.55, p = 0.01). Conclusion Significant relationships exist between smoking and readmission for patients with psychiatric illness. Smokers are more likely to be readmitted within 30 days or one year after discharge. Interaction of smoking and certain specific diagnoses significantly increases readmission. Smoking rates are high among people with psychiatric illness. Significant associations exist between smoking and readmission for psychiatric patients. Smokers are more likely to be readmitted within 30 days or one year of discharge. Interaction of smoking and some psychiatric diagnoses increases readmission chances.

Abstract
UNLABELLED This systematic review and meta-analysis summarized the results from nine eligible observational studies. Lithium use was significantly associated with a decrease risk of fractures. INTRODUCTION The association between lithium use and risk of fracture is uncertain. To date, there have been no meta-analyses that have studied the association between the two. We conducted a systematic review and meta-analysis to examine the effect of lithium medication on the risk of fracture. METHODS A comprehensive literature search was performed in PubMed, Embase, and MEDLINE to include eligible observational studies. Three reviewers conducted the literature search, study selection, study appraisal, and data abstraction independently. Random effects models were used to obtain the overall estimate for meta-analysis. Cochran's Q and Higgins' I2 were used to assess heterogeneity. A funnel plot and Egger's regression test were employed to assess publication bias. RESULTS Of the 3819 studies that were identified by our search strategy, eight were eligible for the systematic review, while seven of them qualified for the meta-analysis. In studies that reported risk ratio (RR) of fracture as an outcome (five studies [n = 1,134,722]), lithium use was associated with a 20% decrease in risk of fracture (RR = 0.80; 95% CI, 0.73-0.87; p < 0.01). A decreased risk of fracture associated with lithium was also observed in studies that adjusted for previous fractures (RR = 0.81; 95% CI, 0.73-0.89; p < 0.01). The decreased risk of fracture associated with lithium use remained consistent in all the analyses with different inclusion criteria. Neither significant heterogeneity nor significant publication bias was observed. CONCLUSION The present systematic review and meta-analysis demonstrated that lithium use was associated with a significant decreased risk of fracture.

Abstract
Few studies have compared the prevalence of smoking between patients with bipolar disorder, major depressive disorder (MDD) and schizophrenia. This study examined the prevalence of smoking and its relationships with demographic and clinical characteristics, and quality of life (QOL) in patients with these psychiatric disorders. A total of 1,102 inpatients were consecutively screened. Psychopathology and QOL were measured with standardized instruments. The prevalence of current smoking in the whole sample was 16.7%; 17.5% in bipolar disorder, 10.6% in MDD and 18.5% in schizophrenia. The rates of smoking in bipolar disorder (p = 0.004, OR = 2.5, 95%CI: 1.3–4.7) and schizophrenia (p = 0.03, OR = 2.0, 95%CI: 1.06–3.8) were significantly higher than in MDD, while no difference was found between bipolar disorder and schizophrenia. Smokers had a higher mental QOL than non-smokers (p = 0.007) in MDD, but no difference was found in the other two groups. Male gender, living alone, higher personal income, older age of onset, health insurance coverage, and first episode was significantly associated with smoking in one or more diagnostic groups. Smoking appears more common in bipolar disorder and schizophrenia than in MDD in China. The figures in all disorders were lower than that reported in most of other countries.

Abstract
It is not known why mentally ill persons smoke excessively. Inasmuch as endogenous opioid and dopaminergic systems are involved in smoking reinforcement, it is important to study mu opioid receptor (OPRM1) A118G (rs1799971), dopamine D2 receptor (DRD2) Taq1A (rs1800497) genotypes, and sex differences among patients with schizophrenia or bipolar disorder. Smokers and nonsmokers with schizophrenia (n=177) and bipolar disorder (n=113) were recruited and genotyped. They were classified into three groups: current smoker, former smoker, and never smoker by tobacco smoking status self-report. The number of cigarettes smoked per day was used as the major tobacco smoking parameter. In patients with schizophrenia, tobacco smoking prevalence was greater in males than in females as expected, but women had greater daily cigarette consumption (p<0.01). Subjects with schizophrenia who had the OPRM1 *G genotype smoked more cigarettes per day than the AA allele carriers with schizophrenia (p<0.05). DRD2 Taq1A genotype differences had no effect on the number of cigarettes smoked per day. However, female smokers with schizophrenia who were GG homozygous of the DRD2 receptor smoked more than the *A male smokers with schizophrenia (p<0.05). In bipolar patients, there were no OPRM1 and DRD2 Taq1A genotype differences in smoking status. There also were no sex differences for smoking behavior among the bipolar patients. The results of this study indicate that single nucleotide polymorphism (SNP) of the less functional mu opioid receptor increases tobacco smoking in patients with schizophrenia. Alteration of DRD2 receptor function also increased smoking behavior in females with schizophrenia.

Abstract
OBJECTIVES Worldwide studies were combined to examine two hypotheses: (i) bipolar disorder is associated with smoking behaviors, compared with the general population; and (ii) smoking behavior prevalences in bipolar disorder are intermediate between those in major depressive disorder and those in schizophrenia. METHODS Combined analyses used 56 articles on adults obtained from a PubMed search or the senior author's article collection. Odds ratios (ORs) and their 95% confidence intervals (CIs) compared current smoking, heavy smoking among current smokers, smoking cessation in ever smokers, and ever smoking in bipolar disorder versus control groups. RESULTS The combined OR was 3.5 (CI: 3.39-3.54) in 51 current smoking studies of bipolar disorder versus the general population from 16 countries. More limited data provided an OR = 0.34 (CI: 0.31-0.37) for smoking cessation and an OR = 3.6 (CI: 3.30-3.80) for ever smoking. The combined OR was 0.76 (CI: 0.74-0.79) for current smoking in bipolar disorder versus schizophrenia in 20 studies from ten countries. Ever smoking may be lower in bipolar disorder than in schizophrenia (OR = 0.83, CI: 0.75-0.91). The OR was 2.05 (CI: 2.00-2.10) for current smoking in bipolar disorder versus major depression in 18 studies from seven countries. Ever smoking may be higher (OR = 1.5, CI: 1.40-1.70) and smoking cessation lower (OR = 0.51, CI: 0.45-0.59) in bipolar disorder than in major depression. CONCLUSIONS Increased current smoking in bipolar disorder versus the general population reflected increased ever smoking (initiation) and decreased smoking cessation. Smoking behavior frequencies in bipolar disorder may be between those in depressive disorder and schizophrenia, with schizophrenia showing the highest severity level.

Abstract
Research is limited on the effects of regular substance use on mental health-related outcomes. We used a large nationally representative survey to examine current and future quality of life and risk of psychiatric disorders among past-year regular (weekly) users of alcohol, nicotine, and cannabis. Data on psychiatric disorders and quality of life from two waves (Wave 1 N = 43,093, Wave 2 N = 34,653) of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) were used to test study aims. In cross-sectional analyses, regular nicotine and cannabis use were associated with higher rates of psychiatric disorder, though regular alcohol use was associated with lower rates of disorders. Prospective analyses found that regular nicotine use predicted onset of anxiety, depressive, and bipolar disorders. Regular alcohol use predicted lower risk of these disorders. Regular cannabis use uniquely predicted the development of bipolar disorder, panic disorder with agoraphobia, and social phobia. Lastly, regular alcohol use predicted improvements in physical and mental health-related quality of life, whereas nicotine predicted deterioration in these outcomes. Regular cannabis use predicted declines in mental, but not physical health. These data add to the literature on the relations between substance use and mental and physical health and suggest increased risk of mental health problems among regular nicotine and cannabis users and better mental and physical health among regular alcohol users. Examination of mechanisms underlying these relationships is needed.

Abstract
BACKGROUND Bipolar disorder (BD) is associated with an increase of psychiatric and physical comorbidities, but the effects of these disorders on general hospital-based mortality are unclear. Consequently, we investigated whether the burden of comorbidity and its relevance on hospital-based mortality differed between individuals with and without BD during a 12.5-year observation period in general hospital admissions. METHODS During 1 January 2000 and 30 June 2012, 621 individuals with BD were admitted to three General Manchester Hospitals. All comorbidities with a prevalence ≥1% were compared with those of 6210 randomly selected and group-matched hospital controls of the same age and gender, regardless of priority of diagnoses. Comorbidities that increased the risk for hospital-based mortality (but not mortality outside of the hospitals) were identified using multivariate logistic regression analyses. RESULTS Individuals with BD had a more severe course of disease than controls that was associated with a higher total number of in-hospital deaths. Individuals with BD compared to controls had a substantial higher burden of comorbidities, the most frequent comorbidities included asthma, type-2 diabetes mellitus (T2DM), and alcohol dependence. 18 other diseases with a surplus of diabetes related complications were also increased. Fourteen comorbidities contributed to the prediction of hospital-based mortality in univariate analyses. Risk factors for hospital-based mortality in multivariate analyses were ischemic stroke, pneumonia, bronchitis, chronic obstructive pulmonary disease, T2DM, and hypertension. The impact of T2DM on hospital-based mortality was higher in individuals with BD than in controls. LIMITATIONS The study design was not assigned to assess the type of BD, the current bipolar status, and if individuals with BD were treated with medication. It was neither possible to compare drug effects, nor to compare the adherence to treatment between samples. CONCLUSION In one of the largest samples of individuals with BD in general hospitals, the excess comorbity in individuals with BD compared to controls is in particular caused by asthma and T2DM. T2DM and its complications cause significant excess hospital-based mortality in individuals with BD.

Abstract
Bipolar disorder is a highly recurrent disease which requires long-term treatment. Dropout is a major problem, poorly understood. The objectives of this study were to know the risk of dropout of a cohort of bipolar patients under ambulatory treatment and to identify the clinical profile of patients more likely to abandon the follow-up. A sample of 285 BD I and II patients was followed up for a mean of 2.87 years. A significant proportion of patients failed regular follow-up. The dropout rates were 6.3 % at three months, 12.7 % at 6 months, and 17.6, 27.2, 37.3, 44.0, 47.2 and 49.0 % at 1, 2, 3, 4, 5 and 6 years respectively. Very few variables at baseline predicted dropout. Patients under 35 years of age were more likely to dropout than older cases. Seasonality, smoking and specially history of poor treatment compliance were strong predictors of dropout. Given the magnitude of dropout, additional early clinical interventions should be considered for high-risk patients.

Abstract
BACKGROUND AND OBJECTIVES Compared to the general population cigarette smoking prevalence is elevated in psychiatric disorders such as schizophrenia (SZ), bipolar disorder (BD), and major depressive disorder (MDD). These disorders are also associated with neurocognitive impairments. Cigarette smoking is associated with improved cognition in SZ. The effects of smoking on cognition in BD and MDD are less well studied. METHODS We used a cross-sectional design to study neuropsychological performance in these disorders as a function of smoking status. Subjects (N = 108) were SZ smokers (n = 32), SZ non-smokers (n = 15), BD smokers (n = 10), BD non-smokers (n = 6), MDD smokers (n = 6), MDD non-smokers (n = 10), control smokers (n = 12), and control non-smokers (n = 17). Participants completed a neuropsychological battery; smokers were non-deprived. RESULTS SZ subjects performed significantly worse than controls in select domains, while BD and MDD subjects did not differ from controls. Three verbal memory outcomes were improved in SZ smokers compared with non-smokers; smoking status did not alter performance in BD or MDD. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE These data suggest that smoking is associated with neurocognitive improvements in SZ, but not BD or MDD. Our data may suggest specificity of cigarette-smoking modulation of neurocognitive deficits in SZ.

Prevalence of nurses' smoking habits in psychiatric and general hospitals in China. Arch Psychiatr Nurs 2014; 28:119-22. [PMID: 24673786 DOI: 10.1016/j.apnu.2013.11.008] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2013] [Revised: 11/17/2013] [Accepted: 11/21/2013] [Indexed: 11/23/2022]
Abstract
This study determined the prevalence of lifetime and current smoking and the correlates of current smoking in nurses working in psychiatric and general hospitals in China. Of 807 distributed questionnaires, 799 nurses who were working in two psychiatric hospitals (n=387, 48.4%), and one general hospital (n=412, 51.6%) had analyzable data. Socio-demographic, alcohol use and smoking data were collected with a self-reported questionnaire. Work-related stress was evaluated with the Nurse Stress Inventory. In the whole sample, the lifetime smoking prevalence was 7.6% (females=2.1% vs. males=48.9%, p<0.0001; psychiatric nurses=14.5% vs. non-psychiatric nurses=1.2%, p<0.0001). The prevalence of current smoking was 7.1% (females=2.1% vs. males=44.7%, p<0.0001; psychiatric nurses=13.4% vs. non-psychiatric nurses=1.2%, p<0.0001). In a multiple logistic regression analysis, age 30 years or older, male gender, having children, being a psychiatric nurse and alcohol consumption were positively associated with smoking, while being a nursing officer was negatively associated with smoking (r(2) = 0.513, p<0.0001). Considering the harmful effects of smoking as well as second-hand smoking in the presence of children, effective measures to promote smoking cessation for male, older and psychiatric nurses and those with children are warranted.

Abstract
AbstractTobacco dependence is the most common substance use disorder in adults with mental illness. The prevalence rates for tobacco dependence are two to four times higher in these patients than in the general population. Smoking has a strong, negative influence on the life expectancy and quality of life of mental health patients, and remains the leading preventable cause of death in this group. Despite these statistics, in some countries smokers with mental illness are disadvantaged in receiving intervention and support for their tobacco dependence, which is often overlooked or even tolerated. This statement from the European Psychiatric Association (EPA) systematically reviews the current evidence on tobacco dependence and withdrawal in patients with mental illness and their treatment. It provides seven recommendations for the core components of diagnostics and treatment in this patient group. These recommendations concern: (1) the recording process, (2) the timing of the intervention, (3) counselling specificities, (4) proposed treatments, (5) frequency of contact after stopping, (6) follow-up visits and (7) relapse prevention. They aim to help clinicians improve the care, health and well-being of patients suffering from mental illness.

Abstract
Only a few studies have examined the efficacy and safety of smoking cessation programmes in patients with mental disorders. The aim of this paper is to describe in detail the methodology used in the study as well as the Multi-component Smoking Cessation Support Programme in terms of pharmacological treatments and psychological interventions. An open-label 9-month follow-up study was conducted in Spain. A total of 82 clinically stable outpatients with schizophrenia, schizoaffective or bipolar disorder were enrolled. Treatment consisted of a programme specifically developed by the research team for individuals with severe mental disorders. The programme consisted of two phases: (1) weekly individual motivational therapy for 4–12 weeks, and (2) a 12-week active treatment phase. During this phase, at each study visit patients received a one- or two-week supply of medication (transdermal nicotine patches, varenicline or bupropion) with instructions on how to take it, in addition to group psychotherapy for smoking cessation. Evaluations were performed: (1) at the time of enrolment in the study, (2) during the 12-week active treatment phase of the study (weekly for the first 4 weeks and then biweekly), and (3) after the end of this phase (two follow-up assessments at weeks 12 and 24). Evaluations included: (1) smoking history, (2) substance use, (3) psychopathology, (4) adverse events, and (5) laboratory tests. The importance of this study lies in addressing a topical issue often ignored by psychiatrists: the unacceptably high rates of tobacco use in patients with severe mental disorders.

Abstract
The association between smoking and psychiatric disorders (PD) has been known for many years. Support for smoking cessation among patients with PD is provided in advanced nations, but there is a little support for smoking cessation among patients with PD in Japan, where few studies have investigated the smoking rate. The aim of the present study is to determine the smoking rate and smoking habits of Japanese patients with PD. The subjects included outpatients who visited the outpatient psychiatric clinic at a University hospital between January and March of 2011. They answered a questionnaire consisting of questions about their sociodemographic background and smoking habits. In an analysis of 733 subjects, the overall smoking rate was 25.1%. The smoking rates among the patients with schizophrenia and depression were 17.3% and 23.9%, respectively, and these rates were lower than the results of previous studies. Among the current smokers, 43.4% had experienced smoking cessation, and only 26.1% were not interested in smoking cessation. Of the current smokers, 37.5% spent between US$128.88 and US$257 per month on cigarettes.

Abstract
The objective of this study was to examine the relationship between Axis I and II mental disorders, quality of life, and nicotine dependence cessation in a nationally representative sample. Data came from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative survey of adults in the United States (N = 34,653). People who met DSM-IV criteria for nicotine dependence previously but who had abstained from nicotine in the last year (nicotine cessation) were compared to people currently dependent on nicotine as well as lifetime abstainers using multivariate logistic regression. Outcomes of interest included DSM-IV Axis I and II mental disorders, treatment seeking for mental disorders, and quality of life measures. In adjusted models, individuals who ceased nicotine use in the last year were less likely to have past-year mood [adjusted odds ratio (AOR) = 0.64; 95% confidence interval (CI) 0.50-0.82, p < 0.001] and substance use disorders (AOR = 0.65, 95% CI 0.52-0.82, p < 0.001) compared to those with current nicotine dependence. They were also less likely to have narcissistic and borderline personality disorders. Compared to those with current nicotine dependence, cessation was associated with an improved quality of life, both physically (beta = 1.65; standard error 0.40, p < 0.001) and mentally (beta = 2.17, standard error 0.39, p < 0.001). In conclusion, nicotine dependence cessation was associated with reduced likelihood of several mental disorders and a higher quality of life compared to those with current nicotine dependence. These findings provide further support for public health policy aimed at smoking cessation.

Abstract
Bipolar disorder (BD) and nicotine dependence (ND) often co-occur. However, the mechanisms underlying this association remain unclear. We aimed to examine, for the first time in a national and representative sample, the magnitude and direction of the temporal relationship between BD and ND; and to compare, among individuals with lifetime ND and BD, the sociodemographic and clinical characteristics of individuals whose onset of ND preceded the onset of BD (ND-prior) with those whose onset of ND followed the onset of BD (BD-prior). The sample included individuals with lifetime BD type I or ND (n = 7958) from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, n = 43093). Survival analyses and logistic regression models were computed to study the temporal association between ND and BD, and to compare ND-prior (n = 135) and BD-prior (n = 386) individuals. We found that ND predicted the onset of BD and BD also predicted the onset of ND. Furthermore, the risk of developing one disorder following the other one was greatest early in the course of illness. Most individuals with lifetime ND and BD were BD-prior (72.6%). BD-prior individuals had an earlier onset of BD and a higher number of manic episodes. By contrast, ND-prior individuals had an earlier onset of both daily smoking and ND, and an increased prevalence of alcohol use disorder. In conclusion, ND and BD predict the development of each other. The phenomenology and course of ND and BD varied significantly depending on which disorder had earlier onset.

Abstract
Previous research has reported that bipolar disorder and schizophrenic patients evidence sensory gating deficits. The use of intermediate phenotypes may facilitate genetic studies. Four single nucleotide polymorphisms (SNPs) located on the non-duplicated region of the alpha-7 nicotinic receptor gene (CHRNA7) were genotyped in 95 healthy subjects, 127 bipolar disorder and 153 schizophrenic patients. We evaluated the association of these polymorphisms with P50 evoked potential measures. Our results do not support a role for the candidate gene in this neurophysiological disturbance.

Abstract
OBJECTIVE Despite the high prevalence of risk factors for obstructive sleep apnea (OSA) among individuals with bipolar disorder, the presence of sleep-disordered breathing has not been systematically assessed in this population. In this study, we sought to determine the level of risk for OSA in a population of remitted individuals with a diagnosis of bipolar I disorder. METHODS A total of 72 individuals with a diagnosis of bipolar I disorder, all of whom were overweight by the World Health Organization criteria, completed the Berlin Questionnaire, a self-assessment tool to establish risk for OSA. RESULTS Over half of this study population (54.1%) was found to be in the high-risk category for OSA. Participants at high risk for OSA scored significantly higher on measures of both depression and mania, even when sleep items were not counted in the total scores. CONCLUSIONS Sleep apnea may be prevalent in patients with bipolar I disorder. Considering the substantial overlap of symptoms between OSA and depression and the potentially harmful effects of sleep disruption in patients with mood disorders, a systematic screening to assess prevalence and associated features of OSA in patients with bipolar disorder is warranted.

Abstract
OBJECTIVES Cigarette smoking behavior in bipolar disorder (BPD), including the effects of mood-stabilizing medications, has not been well characterized. METHODS We compared serum nicotine, nicotine metabolite levels, and smoking topography in 75 smokers with BPD to 86 control smokers (CON). For some comparisons, an additional control group of 75 smokers with schizophrenia (SCZ) were included. RESULTS There were no differences between the BPD and CON groups in baseline smoking characteristics or serum nicotine or cotinine levels. Fifty-one smokers with BPD (68.9%) were taking one of the following mood stabilizers: valproic acid, lamotrigine, carbamazepine, oxcarbazepine, lithium, or topiramate. The 3-hydroxycotinine-to-cotinine ratio, a marker of cytochrome P450 2A6 (CYP2A6) metabolic activity, was significantly higher in BPD versus CON and versus SCZ (0.68 versus 0.49 versus 0.54; p =0.002). The difference between groups, however, was no longer significant when the analysis was repeated with those taking hepatic enzyme-inducing drugs (carbamazepine, oxcarbazepine, and topiramate) included as a covariate. The time between puffs, or interpuff interval (IPI), was shorter in BPD versus CON by an average of 3.0sec (p<0.05), although this was no longer significant when we removed smokers from the analysis of those taking hepatic enzyme inducers. CONCLUSIONS Smokers with BPD are not different from CON on most measures of nicotine intake and smoking topography. We found an increased rate of nicotine metabolism in smokers taking mood stabilizers that are hepatic enzyme inducers, including carbamazepine, oxcarbazepine, and topiramate. Smokers with rapid nicotine metabolism might be expected to smoke more intensely to compensate for the more rapid disappearance of nicotine from the blood and brain, and may have more difficulty in quitting smoking, although this requires further study.

Abstract
No prospective studies of first psychotic episodes have explored sex differences in smoking cessation. The aim of this study was to determine the influence of sex and substance abuse on smoking cessation during an 8-year follow-up of patients after a first psychotic episode. Logistic regression modeling was used to identify factors associated with smoking cessation by sex. To examine for sex variable interactions, the following two methods were used: 1) for other clinical variables, mixed analyses were calculated; and 2) for use of other substances, logistic regression models were performed only in the substance users. At baseline, 79% of men and 84% of women were current smokers. Lower smoking cessation after 8 years was associated with female sex (odds ratio, OR=0.30; 95% confidence intervals, CIs=0.12-0.75) and treatment with typical antipsychotics (OR=0.30, CIs=0.10-0.93). In a logistic regression model of alcohol users, those who used alcohol continuously were less likely to stop smoking (adjusted OR=0.22, CI=0.05-1.0). Among patients who continued using cannabis, female sex was associated with significant lower smoking cessation (adjusted OR=0.03, CI=0.001-0.77). Sex may act as a moderator in smoking cessation after a first psychotic episode. Smoking cessation interventions in these patients should consider sex differences and comorbidity with alcohol and cannabis use.

Abstract
OBJECTIVE Owing to the clinical relationship between bipolar disorder and nicotine dependence, we investigated two research questions: (i) are genetic associations with nicotine dependence different in individuals with bipolar disorder as compared with individuals without bipolar disorder, and (ii) do loci earlier associated with nicotine dependence have pleiotropic effects on these two diseases. METHOD Our study consisted of 916 cases with bipolar disorder and 1028 controls. On the basis of known associations with nicotine dependence, we genotyped eight single-nucleotide polymorphisms (SNPs) on chromosome 8 (three bins) in the regions of CHRNB3 and CHRNA6, and six SNPs on chromosome 15 (three bins) in the regions of CHRNA5 and CHRNA3. RESULTS To determine whether the genetic associations with nicotine dependence are different in bipolar disorder than in the general population, we compared allele frequencies of candidate SNPs between individuals with nicotine dependence only and individuals with both nicotine dependence and bipolar disorder. There were no statistical differences between these frequencies, indicating that genetic association with nicotine dependence is similar in individuals with bipolar disorder as in the general population. In the investigation of pleiotropic effects of these SNPs on bipolar disorder, two highly correlated synonymous SNPs in CHRNB3, rs4952 and rs4953, were significantly associated with bipolar disorder (odds ratio 1.7, 95% confidence interval: 1.2-2.4, P=0.001). This association remained significant both after adjusting for a smoking covariate and analyzing the association in nonsmokers only. CONCLUSION Our results suggest that (i) bipolar disorder does not modify the association between nicotine dependence and nicotinic receptor subunit genes, and (ii) variants in CHRNB3/CHRNA6 are independently associated with bipolar disorder.

Abstract
Tobacco smoking is common in people with bipolar disorder, and rates of smoking cessation are lower than in the general population. A literature review found eleven clinical research publications on bipolar disorder and tobacco, including only one smoking cessation pharmacotherapy trial. This article will review these findings and discuss possible reasons for the high rates of tobacco addiction among persons with bipolar disorder, as well as specific vulnerability factors that may contribute to tobacco treatment failure. An approach to the clinical assessment and treatment of tobacco dependence is described for this sub-group of smokers. Finally, recommendations are made for planning future treatment studies in persons with bipolar disorder and nicotine dependence.

Psychiatric disorders have traditionally been segregated from medical disorders in terms of drugs, treatment, insurance coverage and training of clinicians. This segregation is consistent with the long-standing observation that there are inherent differences between psychiatric disorders (diseases relating to thoughts, feelings and behavior) and medical disorders (diseases relating to physical processes). However, these differences are growing less distinct as we improve our understanding of the roles of epistasis and pleiotropy in medical genetics. Both psychiatric and medical disorders are predisposed in part by genetic variation, and psychiatric disorders tend to be comorbid with medical disorders. One hypothesis on this interaction posits that certain combinations of genetic variants (epistasis) influence psychiatric disorders due to their impact on the brain, but the associated genes are also expressed in other tissues so the same groups of variants influence medical disorders (pleiotropy). The observation that psychiatric and medical disorders may interact is not novel. Equally, both epistasis and pleiotropy are fundamental concepts in medical genetics. However, we are just beginning to understand how genetic variation can influence both psychiatric and medical disorders. In our recent work, we have discovered gene networks significantly associated with psychiatric and substance use disorders. Invariably, these networks are also significantly associated with medical disorders. Recognizing how genetic variation can influence both psychiatric and medical disorders will help us to understand the etiology of the individual and comorbid disease phenotypes, predict and minimize side effects in drug and other treatments, and help to reduce stigma associated with psychiatric disorders.

Abstract
INTRODUCTION Individuals with alcohol, drug, or mental (ADM) disorders combined make up over 40% of all smokers in the U.S. Primary care providers (PCPs) play an important role in smoking cessation counseling, but their effectiveness with this population is unclear. This study evaluated the effectiveness of PCP smoking cessation counseling for smokers with ADM disorders. METHODS Probit regressions conducted in 2009-2010 examined the relationship between past year PCP smoking cessation counseling and successful quitting among 1,356 adults who reported smoking in the 1998-1999 Community Tracking Study survey and who reported seeing a PCP in the past year in the follow-up 2000-2001 Healthcare for Communities Survey. Past year PCP exercise counseling was used as an instrumental variable for past year PCP smoking cessation counseling to account for potential hidden bias between smoking status and receipt of smoking cessation counseling. RESULTS Smokers with and without ADM disorders were equally likely to receive smoking cessation counseling (72.9% vs. 69.9%). Using the instrumental variable approach, smoking cessation counseling by PCPs was significantly associated (p < .01) with quitting among both groups. Predicted probabilities of quitting without smoking cessation counseling were 6.0% for smokers with ADM disorders and 10.5% for smokers without ADM disorders. Predicted probabilities of quitting with smoking cessation counseling were 31.3% for smokers with ADM disorders and 34.9% for smokers without ADM disorders. CONCLUSIONS This study shows that PCPs can help smokers with ADM disorders successfully quit. These smokers should be targeted for smoking cessation counseling to reduce the health burden of tobacco.

Abstract
INTRODUCTION This study examines differences in smoking behaviors between adults with and without serious psychological distress (SPD) in California, which has the longest running comprehensive tobacco control program in the world. METHODS Cross-sectional data from the 2007 California Health Interview Survey on 50,880 noninstitutionalized adults were used to analyze smoking prevalence, cigarette consumption, and quit ratio. Persons with SPD were identified using the K6 scale, a clinically validated psychological screening instrument. RESULTS About 3.8% of California adults screened positive for SPD in the past 30 days (acute SPD) and an additional 4.8% screened positive for SPD in the past 2-12 months (recent SPD). Persons with SPD were more likely to be current smokers than those without SPD (adjusted odds ratios [AOR] = 2.54, 95% CI = 2.02-3.19 for acute SPD and AOR = 2.20, 95% CI = 1.79-2.71 for recent SPD). Current smokers with acute SPD were more likely to smoke ≥20 cigarettes daily than those without SPD (AOR = 1.59, 95% CI = 1.06-2.39). The quit rate was lower among ever-smokers with acute (AOR = 0.46, 95% CI = 0.35-0.62) or recent SPD (AOR = 0.55, 95% CI = 0.42-0.71) than those without SPD. While persons with acute or recent SPD comprised 8.6% of adults, they consumed 19.2% of all cigarettes in California. CONCLUSIONS In California, adults with SPD were more likely to be current smokers and to smoke heavily and less likely to quit than those without SPD. The findings underscore the need for effective smoking cessation strategies targeting this group.

Abstract
OBJECTIVES Tobacco use is prevalent among people living with bipolar disorder. We examined tobacco use, attempts to quit, and tobacco-related attitudes and intentions among 685 individuals with bipolar disorder who smoked ≥ 100 cigarettes in their lifetime. METHODS Data were collected online through the website of the Depression and Bipolar Support Alliance, a mood disorder peer-support network. RESULTS The sample was 67% female, 67% aged 26 to 50, and 89% Caucasian; 87% were current smokers; 92% of current smokers smoked daily, averaging 19 cigarettes/day (SD=11). The sample began smoking at a mean age of 17 years (SD=6) and smoked a median of 7 years prior to bipolar disorder diagnosis. Among current smokers, 74% expressed a desire to quit; intent to quit smoking was unrelated to current mental health symptoms [χ(2) (3)=5.50, p=0.139]. Only 33% were advised to quit smoking by a mental health provider, 48% reported smoking to treat their mental illness, and 96% believed being mentally healthy was important for quitting. Ex-smokers (13% of sample) had not smoked for a median of 2.7 years; 48% quit 'cold turkey.' Most ex-smokers (64%) were in poor or fair mental health when they quit smoking. At the time of the survey, however, more ex-smokers described their mental health as in recovery than current smokers [57% versus 40%; χ(2) (3)=11.12, p=0.011]. CONCLUSIONS Most smokers living with bipolar disorder are interested in quitting. The Internet may be a useful cessation tool for recruiting and potentially treating smokers with bipolar disorder who face special challenges when trying to quit and rarely receive cessation treatment from their mental health providers.

Abstract
OBJECTIVE To compare the use and reliability of self-reported tobacco use (both smoked and smokeless) among patients with bipolar disorder and somatoform disorders. MATERIALS AND METHODS The study was conducted at psychiatry out-patient department of a tertiary care hospital. A total of 50 consecutive patients were recruited. The subjects were asked about the use of tobacco products (smoked as well as smokeless) over the past one week. Those reporting affirmatively in response to the question were assessed using Fagerstrom Test for Nicotine Dependence (FTND) scales. Quantitative urinary cotinine levels were assessed using Enzyme-linked immunosorbent assay (ELISA). RESULTS Calculation of Cohen's kappa using cross tabulation revealed discordance between the self-reported use of smoked as well as smokeless tobacco products in both the groups. Analysis using the lower cut off of 50 ng/ ml also revealed discordance between the self-reported tobacco use (smoked as well as smokeless) for both the groups. CONCLUSIONS The reliability of self-report is questionable among both these groups for smoking as well as smokeless tobacco products.

Abstract
BACKGROUND It is well established that smoking rates in people with common mental disorders such as anxiety or depressive disorders are much higher than in people without mental disorders. It is less clear whether people with these mental disorders want to quit smoking, attempt to quit smoking or successfully quit smoking at the same rate as people without such disorders. METHODS We used data from the 2005 Cancer Control Supplement to the United States National Health Interview Survey to explore the relationship between psychological distress as measured using the K6 scale and smoking cessation, by comparing current smokers who had tried unsuccessfully to quit in the previous 12 months to people able to quit for at least 7 to 24 months prior to the survey. We also used data from the 2007 Australian National Survey of Mental Health and Wellbeing to examine the relationship between psychological distress (K6) scores and duration of mental illness. RESULTS The majority of people with high K6 psychological distress scores also meet diagnostic criteria for mental disorders, and over 90% of these people had first onset of mental disorder more than 2 years prior to the survey. We found that people with high levels of non-specific psychological distress were more likely to be current smokers. They were as likely as people with low levels of psychological distress to report wanting to quit smoking, trying to quit smoking, and to have used smoking cessation aids. However, they were significantly less likely to have quit smoking. CONCLUSIONS The strong association between K6 psychological distress scores and mental disorders of long duration suggests that the K6 measure is a useful proxy for ongoing mental health problems. As people with anxiety and depressive disorders make up a large proportion of adult smokers in the US, attention to the role of these disorders in smoking behaviours may be a useful area of further investigation for tobacco control.

Abstract
OBJECTIVES Despite recent advances in understanding the causes and treatment of nicotine dependence among individuals with psychiatric disorders, smoking among individuals with bipolar disorder (BD) has received little attention. The goal of this review is to synthesize the literature on the epidemiology, consequences, and treatment of smoking and nicotine dependence among individuals with BD and to delineate a future research agenda. METHODS We conducted a PubMed search of English-language articles using the search terms bipolar disorder, mania, tobacco, nicotine, and smoking, followed by a manual search of the literature cited in the identified articles. Articles were chosen by the authors on the basis of their relevance to the topic areas covered in this selective review. RESULTS Adults with BD are two to three times more likely to have started smoking and, on the basis of epidemiological data, may be less likely to initiate and/or maintain smoking abstinence than individuals without psychiatric disorders. Smoking cessation is achievable for individuals with BD, but challenges such as chronic mood dysregulation, high prevalence of alcohol and drug use, more severe nicotine dependence, and limited social support can make quitting more difficult. Effective treatments for tobacco cessation are available, but no controlled trials in smokers with BD have been conducted. CONCLUSIONS Cigarette smoking is a prevalent and devastating addiction among individuals with BD and should be addressed by mental health providers. Additional research on the mechanisms of, and optimal treatment for, smoking and nicotine dependence in this population is desperately needed.

Abstract
BACKGROUND Tobacco smoking is more prevalent among people with mental illnesses, including bipolar disorder, than in the general community. Most data are cross-sectional, and there are no prospective trials examining the relationship of smoking to outcome in bipolar disorder. The impact of tobacco smoking on mental health outcomes was investigated in a 24-month, naturalistic, longitudinal study of 240 people with bipolar disorder or schizoaffective disorder. METHOD Participants were interviewed and data recorded by trained study clinicians at 9 interviews during the study period. RESULTS Comparisons were made between participants who smoked daily (n = 122) and the remaining study participants (n = 117). During the 24-month study period, the daily smokers had poorer scores on the Clinical Global Impressions-Depression (P = .034) and Clinical Global Impressions-Overall Bipolar (P = .026) scales and had lengthier stays in hospital (P = .012), compared with nonsmokers. LIMITATIONS Smoking status was determined by self-report. Nicotine dependence was not measured. CONCLUSION These findings suggest that smoking is associated with poorer mental health outcomes in bipolar and schizoaffective disorder.

Abstract
OBJECTIVE To describe the impact of tobacco, alcohol and cannabis on metabolic profile and cardiovascular risk in bipolar patients. METHOD Naturalistic, cross-sectional, multicenter Spanish study. Current use of tobacco, alcohol and cannabis was determined based on patient self-reports. Metabolic syndrome was defined using the National Health and Nutrition Examination Survey 1999-2000 and the American Heart Association/National Heart, Lung and Blood Institute criteria, and cardiovascular risk using the Framingham and the Systematic Coronary Risk Evaluation functions. RESULTS Mean age was 46.6 years, 49% were male. Substance use: 51% tobacco, 13% alcohol and 12.5% cannabis. Patients who reported consuming any substance were significantly younger and a higher proportion was male. After controlling for confounding factors, tobacco was a risk factor for coronary heart disease (CHD) (unstandardized linear regression coefficient 3.47, 95% confidence interval 1.85-5.10). CONCLUSION Substance use, mainly tobacco, was common in bipolar patients. Tobacco use negatively impacted CHD risk.

Abstract
Treatment outcomes were compared across smokers enrolled in the COMPASS cessation trial with (positive psychiatric history [PH+], n = 271) and without (PH-, n = 271) a diagnosis of PH based on medical record evidence of anxiety, depression, psychotic disorder, or bipolar disorder. Everyone received behavioral counseling plus varenicline and was followed for 6 months post quit date. PH+ smokers took varenicline for fewer days on average (59.4 vs. 68.5, p < or = .01) but did not differ in their use of behavioral treatment. PH+ smokers were more likely to report anxiety and depression, but side-effect intensity ratings did not differ after adjusting for multiple comparisons. Overall, all side effects were rated as moderate intensity or less. Groups had similar 30-day abstinence rates at 6 months (31.5% PH+ vs. 35.4% PH-, p = .35). In sum, having a psychiatric diagnosis in this trial did not predict worse treatment outcome or worse treatment side effects.

Abstract
AIM We analysed the impact of tobacco smoking over several healthy lifestyle habits along with the impact on 10-years cardiovascular event (CVE) risk in the CLAMORS schizophrenia cohort. METHODS This analysis was performed within the scope of the CLAMORS study which included consecutive outpatients meeting DSM-IV criteria for schizophrenia spectrum disorder. Beside smoking history, data on usual healthy lifestyle habits included current exercise, saturated fat sparing diet, low-caloric diet, and daily dietary fibre, salt, caffeine and alcohol consumption were recorded. The 10-year CVE risk was calculated with Framingham function. RESULTS 1704 patients (61.1% male), 18 to 74 years were examined. Prevalence of smoking was 54.54% (95% CI: 52.16%-56.90%) significantly higher than in age and sex matched general population subjects, 31.51% (31.49%-31.52%); OR=2.61 (2.37-2.87, p<0.0001). After controlling by confounders smokers showed a 10-year CVE risk excess versus non-smokers of 2.63 (2.16-3.09), p<0.001. Smoking cessation would reduce the likely of high/very high 10-year CVE risk (above 10%) by near 90% [OR=0.10 (0.06-0.18), p<0.0001]. Also, smokers were more likely to consume alcohol daily [4.13 (3.07-5.54), p<0.0001] and caffeine [3.39 (2.72-4.23), p<0.0001] than non-smoker patients with schizophrenia, and less likely to avoid daily consumption of salt [0.58 (0.43-0.78), p<0.0001], saturated fat [0.71 (0.56-0.91), p=0.006], high fibre diet [0.67 (0.53-0.84), p=0.001], or to follow a low-caloric diet [0.63 (0.48-0.81), p<0.0001]. Smokers also were less likely to do exercise habitually [0.62 (0.48-0.82, p=0.001]. CONCLUSION Compared with the general population, patients with schizophrenia showed significant higher prevalence of smoking. Smokers who stop smoking would benefit by a near 90% reduction in the likely of 10-year cardiovascular event risk above 10%.

Abstract
Over 40% of all US smokers have comorbid alcohol, drug, or mental disorders. Using data from the 2000-2001 Healthcare for Communities survey, we conducted multivariate logistic regressions to examine these individuals' sensitivity to cigarette prices. We found that a 10% increase in cigarette prices was associated with 18.2% less smoking participation among individuals with alcohol, drug, or mental disorders, except those with alcohol dependence. Increasing cigarette taxes could be effective in reducing smoking among individuals with alcohol, drug, or mental disorders.

Abstract
Background Comorbidity of psychiatric and substance use disorders represents a significant complication in the clinical course of both disorders. Bipolar Disorder (BD) is a psychiatric disorder characterized by severe mood swings, ranging from mania to depression, and up to a 70% rate of comorbid Tobacco Use Disorder (TUD). We found epidemiological evidence consistent with a common underlying etiology for BD and TUD, as well as evidence of both genetic and environmental influences on BD and TUD. Therefore, we hypothesized a common underlying genetic etiology, interacting with nicotine exposure, influencing susceptibility to both BD and TUD. Methods Using meta-analysis, we compared TUD rates for BD patients and the general population. We identified candidate genes showing statistically significant, replicated, evidence of association with both BD and TUD. We assessed commonality among these candidate genes and hypothesized broader, multi-gene network influences on the comorbidity. Using Fisher Exact tests we tested our hypothesized genetic networks for association with the comorbidity, then compared the inferences drawn with those derived from the commonality assessment. Finally, we prioritized candidate SNPs for validation. Results We estimate risk for TUD among BD patients at 2.4 times that of the general population. We found three candidate genes associated with both BD and TUD (COMT, SLC6A3, and SLC6A4) and commonality analysis suggests that these genes interact in predisposing psychiatric and substance use disorders. We identified a 69 gene network that influences neurotransmitter signaling and shows significant over-representation of genes associated with BD and TUD, as well as genes differentially expressed with exposure to tobacco smoke. Twenty four of these genes are known drug targets. Conclusions This work highlights novel bioinformatics resources and demonstrates the effectiveness of using an integrated bioinformatics approach to improve our understanding of complex disease etiology. We illustrate the development and testing of hypotheses for a comorbidity predisposed by both genetic and environmental influences. Consistent with our hypothesis, the selected network models multiple interacting genetic influences on comorbid BD with TUD, as well as the environmental influence of nicotine. This network nominates candidate genes for validation and drug testing, and we offer a panel of SNPs prioritized for follow-up.

Abstract
OBJECTIVES Cigarette smoking in individuals with bipolar disorder has been associated with suicidal behavior, although the precise relationship between the two remains unclear. METHODS In this prospective observational study of 116 individuals with bipolar disorder, we examined the association between smoking and suicidality as measured by Linehan's Suicide Behaviors Questionnaire (SBQ) and prospective suicide attempts over a nine-month period. Impulsivity was measured by the Barratt Impulsiveness Scale. RESULTS Smoking was associated with higher baseline SBQ scores in univariate and adjusted analyses, but was not significant after statistical adjustment for impulsivity in a regression model. A higher proportion of smokers at baseline made a suicide attempt during the follow-up period (5/31, 16.1%) compared to nonsmokers (3/85, 3.5%); p = 0.031, odds ratio = 5.25 (95% confidence interval: 1.2-23.5). Smoking at baseline also significantly predicted higher SBQ score at nine months. CONCLUSIONS In this study, current cigarette smoking was a predictor of current and nine-month suicidal ideation and behavior in bipolar disorder, and it is likely that impulsivity accounts for some of this relationship.

Abstract
BACKGROUND Smoking has been associated with a range of mental disorders including schizophrenia, anxiety disorders and depression. People with mental illness have high rates of morbidity and mortality from smoking related illnesses such as cardiovascular disease, respiratory diseases and cancer. As many people who meet diagnostic criteria for mental disorders do not seek treatment for these conditions, we sought to investigate the relationship between mental illness and smoking in recent population-wide surveys. METHODS Survey data from the US National Comorbidity Survey-Replication conducted in 2001-2003, the 2007 Australian Survey of Mental Health and Wellbeing, and the 2007 US National Health Interview Survey were used to investigate the relationship between current smoking, ICD-10 mental disorders and non-specific psychological distress. Population weighted estimates of smoking rates by disorder, and mental disorder rates by smoking status were calculated. RESULTS In both the US and Australia, adults who met ICD-10 criteria for mental disorders in the 12 months prior to the survey smoked at almost twice the rate of adults without mental disorders. While approximately 20% of the adult population had 12-month mental disorders, among adult smokers approximately one-third had a 12-month mental disorder--31.7% in the US (95% CI: 29.5%-33.8%) and 32.4% in Australia (95% CI: 29.5%-35.3%). Female smokers had higher rates of mental disorders than male smokers, and younger smokers had considerably higher rates than older smokers. The majority of mentally ill smokers were not in contact with mental health services, but their rate of smoking was not different from that of mentally ill smokers who had accessed services for their mental health problem. Smokers with high levels of psychological distress smoked a higher average number of cigarettes per day. CONCLUSION Mental illness is associated with both higher rates of smoking and higher levels of smoking among smokers. Further, a significant proportion of smokers have mental illness. Strategies that address smoking in mental illness, and mental illness among smokers would seem to be important directions for tobacco control. As the majority of smokers with mental illness are not in contact with mental health services for their condition, strategies to address mental illness should be included as part of population health-based mental health and tobacco control efforts.

Abstract
Tobacco smoking is an extremely addictive and harmful form of nicotine (NIC) consumption, but unfortunately also the most prevalent. Although disproportionately high frequencies of smoking and its health consequences among psychiatric patients are widely known, the neurobiological background of this epidemiological association is still obscure. The diverse neuroactive effects of NIC and some other major tobacco smoke constituents in the central nervous system may underlie this association. This present paper summarizes the pharmacology of NIC and its receptors (nAChR) based on a systematic review of the literature. The role of the brain's reward system(s) in NIC addiction and the results of functional and structural neuroimaging studies on smoking-related states and behaviors (i.e. dependence, craving, withdrawal) are also discussed. In addition, the epidemiological, neurobiological, and genetic aspects of smoking in several specific neuropsychiatric disorders are reviewed and the clinical relevance of smoking in these disease states addressed.

Abstract
We discuss potential explanations for the high prevalence of tobacco use and tobacco dependence (TD) in people with mental health and addictive (MHA) disorders. The biopsychosocial basis for this comorbidity is presented, integrating evidence from epidemiologic and clinical studies. We also review evidence that suggests a shared vulnerability related to biological, genetic, and environmental factors may be the most parsimonious mechanism to explain the association between TD and MHA disorders. Finally, we review the examples of various MHA disorders that are associated with TD, and suggest avenues for new investigation that could aid in the development of rationale and more effective treatments for tobacco and MHA disorder comorbidities.

Abstract
Cigarette smoking among adults with bipolar disorder (BP) correlates with psychosis, substance use disorders (SUD), and suicidality. Little is known regarding smoking among youths with BP. Youths with BP (n = 441) were divided into three smoking groups: Never, Ever, and Daily. Twenty-five percent reported any smoking (11% daily, 14% ever). Ever and Daily subjects had significantly greater lifetime prevalence of suicide attempts, physical abuse, conduct disorder, and SUD compared to Never subjects. Daily heavy smokers had greater prevalence of SUD and suicide attempts, and worse depression versus daily light smokers. Smoking among youths with BP is independently associated with suicide attempts and SUD.

Abstract
The purpose of this study is to describe possible differences in cognitive functioning between smoking and non-smoking patients with first-episode psychosis and to determine whether there is a better cognitive profile associated with smoking. We assessed 61 first-episode psychosis patients with a neuropsychological battery that included computerized measurements of attention, working memory, and executive functioning. Patients were grouped into two categories: non-smokers (0 cigarettes/day; n = 30) and smokers (>/=20 cigarettes/day; n = 31). No significant differences were detected in sociodemographic and clinical data between the two groups. For attention tasks, smokers exhibited shorter reaction times in the sustained attention test than non-smokers (P = 0.039) and needed less time to complete the Stroop interference test (P = 0.013). In the working memory task, smokers exhibited shorter reaction times (P = 0.029) and presented a significantly lower percentage of omission (P = 0.002) and commission errors (P = 0.020) than non-smokers. For executive functioning, no differences were detected between groups in performance on the Wisconsin Card Sorting Test. Results indicate that first-episode psychosis patients who are nicotine users have better cognitive functioning in the areas of attention and working memory than patients who are not nicotine users. This study supports the cognitive approach to the self-medication hypothesis, to explain the high rates of cigarette smoking among psychosis patients. These results may be relevant for developing new strategies involving nicotinic receptors for cognitive enhancement in psychosis.

Abstract
OBJECTIVES This study compared the prevalence of tobacco smoking behaviors in patients with bipolar disorder with normal and psychiatric (schizophrenia and major depression) controls. The main goal was to establish that bipolar patients smoke more than normal controls. Differences with psychiatric controls were explored. METHODS Samples of 424 patients (99 bipolar, 258 schizophrenia and 67 major depression) and 402 volunteer controls were collected in Central Kentucky. Smoking data for Kentucky's general population were available. Odds ratios (ORs) and their 95% confidence intervals (CIs) were used to establish the strength of associations. Logistic regression was used to adjust ORs for confounding variables. RESULTS Using epidemiological definitions of smoking behaviors and the general population as controls provided bipolar disorder unadjusted ORs of 5.0 (95% CI: 3.3-7.8) for current cigarette smoking, 2.6 (95% CI: 1.7-4.4) for ever cigarette smoking, and 0.13 (95% CI: 0.03-0.24) for smoking cessation. Using a clinical definition and volunteers as controls provided respective bipolar disorder adjusted ORs of 7.3 (95% CI: 4.3-12.4), 4.0 (95% CI: 2.4-6.7), and 0.15 (95% CI: 0.06-0.36). Prevalences of current daily smoking for patients with major depression, bipolar disorder, and schizophrenia were 57%, 66%, and 74%, respectively. CONCLUSIONS Bipolar disorder was associated with significantly higher prevalences of tobacco smoking behaviors compared with the general population or volunteer controls, independently of the definition used. It is possible that smoking behaviors in bipolar disorder may have intermediate prevalences between major depression and schizophrenia, but larger samples or a combination of multiple studies (meta-analysis) will be needed to establish whether this hypothesis is correct.
