Abstract
Introduction: Despite efforts to curb nicotine use, 8.1 million adults in the United States use e-cigarettes. Notably, the majority of nicotine-containing e-cigarette users report wanting to quit in the near future, yet there is a dearth of research surrounding intervention efforts. Cannabidiol (CBD) has potential to facilitate e-cigarette quit attempts by decreasing withdrawal symptom intensity and anxiety during nicotine e-cigarette abstinence. Methods: This study employed an open-label, crossover design (n=20) to test the hypothesis that among daily nicotine-containing e-cigarette users, oral administration of 320 mg CBD would reduce self-reported nicotine withdrawal severity and state anxiety following a 4-h e-cigarette abstinence period compared to withdrawal and anxiety reported after abstinence in the absence of CBD. Results: After controlling for participants' positive CBD expectancies, results were consistent with hypotheses, suggesting CBD reduced both nicotine withdrawal symptom severity and state anxiety during e-cigarette abstinence. Conclusion: These preliminary findings suggest testing the impact of CBD on e-cigarette cessation attempts is warranted.

Abstract
Approximately one-third of adults with chronic respiratory disease (CRD) have comorbid depressive and anxiety disorders; yet these disorders are often unrecognized in this patient population. Transdiagnostic processes such as anxiety sensitivity (AS) are useful for identifying mechanisms underlying psychological and heath conditions. The Short-Scale AS Index (SSASI) is a brief self-report measure of AS which has potential clinical utility among CRD populations to evaluate psychological distress and inform comprehensive care. The present study investigated the psychometric properties of the SSASI among adults with CRDs. Participants were recruited from a web-based panel of adults with CRDs (n = 768; 49.3% female; 57.8% White) including adults with asthma only (n = 230), COPD only (n = 321), or co-occurring asthma and COPD (n = 217). Participants completed a battery of self-report questionnaires assessing psychological and medical symptoms. Analyses were conducted to examine the factor structure and measurement invariance across CRD groups. Convergent validity and criterion validity of the SSASI were assessed within each group. Results supported partial measurement invariance across CRD groups. The SSASI demonstrated high reliability, convergent validity, and criterion validity with each CRD group. Findings from this study and existing work indicate that the SSASI is an effective and economical assessment tool for identifying patients CRD who may benefit from psychological interventions to reduce AS.

Abstract
Nicotine is the reinforcing ingredient in tobacco. Following chronic exposure, sudden cessation of nicotine use produces negative symptoms of withdrawal that contribute to dependence. The molecular mechanisms underlying nicotine withdrawal behaviors, however, are poorly understood. Using recombinant inbred mice, chronic nicotine was delivered by minipump and withdrawal induced using mecamylamine. Somatic signs of withdrawal, and anxiety-like behavior using elevated plus maze, were then assessed. Interval mapping was used to identify associations between genetic variation and withdrawal behaviors, and with basal gene expression. Differential gene expression following nicotine exposure and withdrawal was also assessed in progenitor mice using microarrays. Quantitative trait loci mapping identified chromosome intervals with significant genetic associations to somatic signs of withdrawal or withdrawal-induced anxiety-like behavior. Using bioinformatics, and association with basal gene expression in nucleus accumbens, we implicated Rb1, Bnip3l, Pnma2, Itm2b, and Kif13b as candidate genes for somatic signs of withdrawal, and Galr1, which showed trans-regulation from a region of chromosome 14 that was associated with somatic signs of withdrawal. Candidate genes within the chromosome 9 region associated with anxiety-like withdrawal behavior included Dixdc1, Ncam1, and Sorl1. Bioinformatics identified six genes that were also significantly associated with nicotine or alcohol traits in recent human genome-wide association studies. Withdrawal-associated somatic signs and anxiety-like behavior had strong non-overlapping genetic associations, respectively, with regions of chromosome 14 and chromosome 9. Genetic, behavioral and gene expression correlations, and bioinformatics analysis identified several candidate genes that may represent novel molecular targets for modulating nicotine withdrawal symptoms.

Abstract
BACKGROUND Black smokers have greater difficulty in quitting and higher rates of smoking-related diseases and disabilities than the general population. The smoking disparities experienced by this group are, in part, a consequence of multiple chronic life stressors (eg, racial discrimination) that engender increased exposure to interoceptive stress symptoms (eg, anxiety), which can ultimately lead to smoking as a means of immediate emotion regulation. OBJECTIVE This study aimed to culturally adapt and initially test a novel mobile intervention (ie, Mobile Anxiety Sensitivity Program for Smoking [MASP]) that targets anxiety sensitivity (AS; a proxy for difficulty and responsivity to interoceptive stress) among Black smokers. The MASP intervention is culturally informed to address interoceptive stress management difficulties among Black smokers and is thus hypothesized to facilitate smoking cessation. METHODS In phase 1, a total of 25 Black smokers with elevated AS will be administered MASP for 6 weeks. Following the completion of phase 1, we will further refine the MASP based on qualitative and quantitative data from participants to produce the final MASP iteration. In phase 2, a total of 200 Black smokers with elevated AS will be enrolled and randomly assigned to receive nicotine replacement therapy and either the smartphone-based National Cancer Institute QuitGuide app for standard mobile smoking cessation treatment or the MASP intervention. All participants in phases 1 and 2 will be enrolled remotely and will complete a web-based study screener; smartphone-based baseline assessment; daily smartphone-based ecological momentary assessments for 6 weeks; phone-based end-of-treatment qualitative interviews; and smartphone-based follow-up assessments at postbaseline weeks 1, 2 (quit date), 3, 4, 5, 6, 28, and 54 (weeks 28 and 54 follow-ups will be completed by phase 2 participants only). The MASP intervention is intended to offset barriers to treatment and encourage treatment engagement via smartphones. RESULTS This project was funded in September 2020. Phase 1 data collection began in January 2022. Phase 2 data collection is scheduled to begin in July 2022. CONCLUSIONS If successful, data from this study will support culturally informed treatment approaches for Black smokers and, pending findings of efficacy, provide an evidence-based mobile intervention for smoking cessation that is ready for dissemination and implementation.

Abstract
Smoking cessation is a global public health issue. Nicotine dependence is a dynamic process that is not limited to physical dependence. Hypnosis can be helpful in the global management of smoking cessation. We explored this effect by comparing the effects of hypnosis and nicotine-replacement therapies (NRT) on tobacco withdrawal.Thirty participants were included in this comparative-randomized pilot study in parallel controlled groups after ethical validation. Participants were recruited by a general practitioner and had standardized consultations with addiction and hypnosis specialists and adapted treatment. The evolution of withdrawal symptoms was compared using the Cigarette Withdrawal Scale-21 for one month after smoking cessation in an adult tobacco-addict population wishing to stop smoking and receiving either NRT or hypnosis, both supported by motivational interviews. Craving intensity (French version of the Tobacco Craving Questionnaire), nicotine dependence (Fagerström), tobacco consumption, anxiety (Hamilton scale), and depression (Montgomery-Asberg scale) were also evaluated. Hypnosis appeared to have an influence on reducing the number of smoked cigarettes, whereas NRT appeared to influence markers of both physical and psychic dependence. A complementarity of hypnosis and NRT may be a viable therapeutic alternative to reduce the intensity of withdrawal symptoms after voluntary smoking cessation. A study on a larger population with a longer follow-up is needed to assess the advantages of each method to quit smoking.

Abstract
A number of rating scales evaluating symptoms of nicotine withdrawal have been developed over the years but insufficient attention has been devoted to the assessment of their clinimetric properties. Clinimetrics, the science of clinical measurements, is an innovative approach, particularly useful for assessing the validity of rating scales. This is the first study using clinimetric principles to test the construct validity of the Smoker Complaint Scale (SCS), a self-rating scale specifically developed to assess acute symptoms of nicotine withdrawal. Construct validity was evaluated via Item Response Theory (IRT) models (i.e., combining Rasch and Mokken analyses). A total of 366 subjects (mean age = 34.0, SD = 11.3 years) participated in the study. IRT analyses showed that SCS was a multidimensional measure of symptoms of nicotine withdrawal, including unidimensional subscales, particularly a four-item subscale (the SCS4), which was found to entail the clinimetric property of construct validity. IRT analyses also revealed that affective symptoms of nicotine withdrawal preceded cognitive ones. The SCS should be considered as an item bank, including a particularly valid subscale, the SCS4 that can be used as a screening or outcome measure to evaluate the severity of cognitive and affective symptoms of nicotine withdrawal. SCS4 is a sensitive clinimetric index which differentiates "ceiling symptoms" of nicotine withdrawal (e.g., "feeling slowed down") from "floor symptoms" of nicotine withdrawal (e.g., "feeling lightheaded") that emerge in the severe form of nicotine withdrawal.

Abstract
BACKGROUND This study examined whether baseline negative emotional states (depression and anxiety) would predict craving for cigarettes and other nicotine withdrawal symptoms in early abstinence and whether those emotional states and withdrawal symptoms would predict failure in quitting smoking at 3 months postquit among U.S. women living with the human immunodeficiency virus (HIV). METHOD The study is a secondary analysis of data from two smoking cessation studies of women living with HIV. Craving for cigarettes and other withdrawal symptoms were assessed weekly with a total of 229 observations during the first 4 weeks following quit day. Descriptive statistics were used to examine baseline characteristics of the participants. A random growth curve model was used to estimate between-person differences in a within-person trend of changes in the withdrawal symptoms. A binary logistic regression analysis was performed to identify predictors of short-term smoking abstinence. RESULTS Baseline anxiety was a predictor of postquit nicotine withdrawal symptoms but baseline depression was not. Neither baseline anxiety nor depression predicted postquit craving for cigarettes. Participants who received an HIV-tailored smoking cessation intervention showed a greater decline in craving symptom than those who received an attention-controlled intervention. HIV-tailored intervention and less craving predicted smoking abstinence at 3-month follow-up. DISCUSSION Compared to an attention-controlled intervention, an HIV-tailored intervention effectively decreased craving for cigarette smoking after quitting-which effectively increased the rate of short-term smoking abstinence in women living with HIV.

Abstract
In this study we provide information on e-cigarette use characteristics in relation to racial and ethnic characteristics in a sample of 535 adult e-cigarette users. We also evaluated how anxiety sensitivity (AS; fear of anxiety) interacted with race/ethnicity to predict vaping outcomes. We found an association between greater AS and higher e-cigarette dependence for White, but not Black, participants. A similar trend was observed for level of risk perception. Also, Hispanic status was associated with higher perception of e-cigarette benefits. Overall, the present study contributes to the understanding of factors linked to e-cigarette use.

Abstract
Abstract
Introduction
Smoking is a lethal public health problem that is common in US military veterans, particularly those with posttraumatic stress disorder (PTSD). Mobile applications (apps) to promote smoking cessation are a scalable and low-cost approach that may facilitate treatment engagement.
Methods
This qualitative study examined the acceptability, user experience, and perceptions of a smoking cessation app, Stay Quit Coach (SQC), when incorporated into evidence-based smoking cessation treatment. US military veterans with PTSD who smoked at least five cigarettes per day for 15 of the past 30 days and stated an interested in cessation were eligible to participate. Participants’ baseline comfort levels with mobile technology was measured using the Perceptions of Mobile Phone Interventions Questionnaire–Patient version (PMPIQ-P). At treatment end, semi-structured qualitative interviews were conducted.
Results
Twenty participants were enrolled and 17 (85.0%) participated in the qualitative interview at treatment end. PMPIQ-P scores at baseline ranged from 4.97 to 5.25 (SDs = 0.73–1.04), reflecting moderately high comfort with mobile technology among participants. Qualitative analyses indicated that most participants: (1) endorsed mobile technology as an appealing format for smoking cessation treatment, due to convenience and instantaneous access; and (2) expressed highest perceived helpfulness for interactive app features. Recommendations to improve SQC clustered into four thematic areas: (1) increasing personalization, (2) including more self-tracking features, (3) increasing visual cues, and (4) sharing progress with peers.
Conclusions
SQC was perceived as an acceptable and useful tool to support smoking cessation in a sample of veteran smokers with PTSD. Qualitative data provided valuable insights that can inform the continued development of SQC and other apps for smoking cessation.
Implications
Given the high lethality associated with cigarette smoking, it is crucial to identify scalable, low-risk strategies to promote smoking cessation, particularly in high-risk populations. Mobile technology is a promising approach that can be used to augment evidence-based smoking cessation treatment. Results of this qualitative study support the use of the SQC mobile app when incorporated into evidence-based smoking cessation treatment for veterans with PTSD and provide future directions for refinement of the SQC app. These findings also highlight the importance of using a patient-centered approach in designing apps intended for a clinical population.

Abstract
BACKGROUND Extant literature shows that adjuvant omega-3-polyunsaturated fatty acids (O3PUFAs) to a standard antidepressant medication impacts favorably on symptoms of depression in participants with major depressive disorders (MDD). The aim of the present study was to investigate, if and to what extent compared to placebo adjuvant O3PUFAs had a favorable impact on symptoms of depression, anxiety, sleep and emotion regulation among outpatients with MDD. METHOD A total of 50 outpatients (mean age: M = 42.46; 68% females) took part in this randomized, double-blind and placebo-controlled study. They were randomly assigned either to the O3PUFA- or to the placebo-condition. Standard medication was sertraline at therapeutic dosages. At baseline, six weeks and 12 weeks later at study completion participants completed questionnaires covering symptoms of depression, anxiety sensitivity, intolerance of uncertainty, sleep disturbances, and emotion regulation. In parallel, experts blind to participants' group assignment rated participants' depression with the Montgomery-Asberg Depression Scale. RESULTS Symptoms of depression (self- and experts' ratings) decreased over time, but more so in the O3PUFA condition, compared to the placebo condition. Likewise, anxiety sensitivity, intolerance of uncertainty and sleep disturbances improved, but again more so in the O3PUFA condition. Further, regulation and control of emotions and perception of other's emotions improved over time, but more so in the O3PUFA condition. CONCLUSIONS Among outpatients with MDD, and compared to placebo, adjuvant O3PUFAs to a standard medication improved not only symptoms of depression, but also dimensions of anxiety and sleep, and above all patients' competencies to regulate their emotions.

Abstract
OBJECTIVE Cigarette smoking remains the leading preventable cause of death in the United States, and withdrawal symptoms are central to the maintenance of tobacco use. Previous research suggests that individual differences in the propensity to experience negative affect may be related to more severe withdrawal symptoms. However, little research has examined how individual differences in the ability to regulate affect (emotion dysregulation) may impact withdrawal symptoms over time. METHOD Therefore, the current study examined the effects of emotion dysregulation on change in tobacco withdrawal symptoms over 12 weeks following a cigarette quit attempt among 188 (Mage = 38.52, SD = 14.00, 46.8% male) treatment seeking smokers. RESULTS Results from the study indicated greater emotion dysregulation was associated with greater quit day withdrawal symptoms as well as with as slower decline in withdrawal symptoms over the 12-week period (B = -0.001, SE = 0.001, p = .046). CONCLUSION The current study offers novel evidence into the role of emotion dysregulation in relation to withdrawal symptoms during a quit attempt. Assessing and reducing heightened emotion dysregulation prior to a quit attempt may be a potentially important therapeutic tactic for helping smokers achieve greater success in managing tobacco withdrawal. PUBLIC HEALTH SIGNIFICANCE STATEMENT This study emphasizes the ways in which emotional dysregulation may affect tobacco withdrawal symptoms. This study can be utilized to further target smoking cessation programs for those attempting to quit smoking.
