Addict Behav 2023; 140:107615. [PMID: 36640662 PMCID: PMC9911383 DOI: 10.1016/j.addbeh.2023.107615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 01/05/2023] [Accepted: 01/06/2023] [Indexed: 01/11/2023]
Abstract
INTRODUCTION Large racial disparities exist in the prevention and treatment of smoking-related diseases, and minoritized populations carry a heavier burden of smoking-related morbidity and mortality. To date, most studies investigating smoking-related illnesses have been conducted in samples in which the majority, or totality, self-identified as White or Caucasian. While Black individuals who smoke tend to have a lower rate of nicotine clearance, in part due to the use of mentholated cigarettes, less is known about how slower clearance affects their acute subjective and physiologic responses in response to either overnight abstinence or subsequent nicotine administration. This study aimed to investigate differences between the experiences of Black and White individuals who smoke across these outcomes after a period of short-term abstinence and after IV nicotine infusion. METHODS The study included 206 smokers (N = 103 Black, N = 103 White, by self-report). The study investigated self-report, physiological, and biochemical smoking-related outcomes following confirmed overnight abstinence followed by IV nicotine infusion. The outcome measures were separately analyzed with repeated-measures mixed-models. RESULTS Black individuals had lower rates of nicotine clearance and were more likely to smoke mentholated cigarettes than White individuals. Despite these differences, no differences in withdrawal, cravings, or physiological outcomes were observed between the two groups. There were some trends toward differences in subjective experiences, in that an interaction with trend level significance between race and dose was observed for negative subjective drug effects, with White smokers trending towards endorsing higher levels of negative affect after abstinence and nicotine infusion. We also observed that Black individuals trended towards experiencing more negative drug effects in response to initial nicotine delivery than to saline, whereas White individuals had no differences in negative drug effects across saline or nicotine doses. CONCLUSIONS Despite slower nicotine clearance, Black participants exhibited withdrawal and urges to smoke as severe as White participants, and did not have blunted physiological responses to overnight abstinence or administration of nicotine, which were contrary to our hypotheses. Our findings suggest minimal differences across races in the acute pharmacologic effects of nicotine. We observed trend-level differences in subjective and affective responses to nicotine. Greater insight into these differences may lead to improved prevention and treatment strategies for smoking-related illnesses for Black individuals who smoke.

Abstract
The assessment of tobacco withdrawal is important for both research and clinical purposes. This study describes the psychometric development of a revised version of the 28-item Wisconsin Smoking Withdrawal Scale (WSWS; Welsch et al., Experimental and Clinical Psychopharmacology, 1999, 7, p. 354). Because the different contexts of use sometimes permit only brief assessment, this revision has produced both a brief and longer form using an updated pool of candidate items. For the revised Wisconsin Smoking Withdrawal Scale 2 (WSWS2), a candidate pool of 37 items was developed to measure nine putative withdrawal constructs. The stem and wording of items were revised as was the response scale. Data for psychometric analyses were derived from three smoking cessation randomized clinical trials conducted at the University of Wisconsin Center for Tobacco Research and Intervention. Dimensionality, internal consistency, and item characteristic analyses of the candidate items were conducted in a derivation sample to ascertain the factor structure and to identify items that could be used in the WSWS2 scales. Confirmatory factor analyses (CFAs) of reduced item sets and factor structure were conducted in two validation samples along with reliability and validity analyses. Derivation and validation sample analyses yielded a longer version of the WSWS2 (WSWS2-L) with 19 items and six subscales (Craving, Negative Affect, Hunger, Sleep, Restlessness, and Concentration) and a brief 6-item version (WSWS2-B). In validation sample analyses, both the WSWS2-L and the WSWS2-B demonstrated good reliability and validity as well as good fit in CFAs. The WSWS2-L and WSWS2-B possess improved construct coverage, fewer items, and other enhancements relative to the WSWS. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Abstract
INTRODUCTION Prior studies have found heightened negative affect following tobacco abstinence in women compared to men. However, experimental work addressing whether these findings generalize across racial groups is scarce. This study investigated whether race (non-Hispanic White vs. non-Hispanic African American) moderated gender differences in abstinence-induced negative affect and smoking behavior. METHODS Data were collected from 2010 to 2017 from two separate laboratory studies investigating experimentally manipulated tobacco abstinence. Following a baseline session, adult daily smokers (≥10 cigarettes/day; women: n = 297, 83.8% non-Hispanic African American; men: n = 492, 86.2% non-Hispanic African American) attended two counterbalanced lab sessions (16 hours abstinent vs. non-abstinent) and completed self-report measures of negative affect followed by a laboratory analogue smoking reinstatement task. RESULTS We found a gender × race interaction for several negative affect states and composite negative affect (βs = -.12 to -.16, Ps < .05). Analyses stratified by race showed that non-Hispanic White women compared to non-Hispanic White men exhibited greater abstinence-induced increases in anger, anxiety, and composite negative affect (βs = -.20 to -.29, Ps < .05). No significant gender differences in abstinence-induced negative affect were found for non-Hispanic African American smokers (βs = .00 to - .04, Ps > .05). CONCLUSION These findings suggest that negative affect during acute tobacco abstinence may be a clinically important and intervenable factor that can inform cessation interventions specifically for non-Hispanic White women smokers. Further empirical exploration of mechanisms underlying interactions of gender and race in tobacco addiction may benefit smoking cessation efforts in non-Hispanic African American women smokers. IMPLICATIONS This study contributes to a scant body of research examining the intersectional influence of race and gender on abstinence-induced negative affect-a central, motivationally prepotent feature of tobacco withdrawal. Using a laboratory-based design to experimentally manipulate abstinence, we provide evidence of a gender × race interaction on negative affect-related withdrawal. Our findings suggest that gender differences in abstinence-induced negative affect observed among non-Hispanic White smokers may not generalize to non-Hispanic African American smokers, highlighting the need for future work to address potential mechanisms underlying the racially discrepant impact of gender on affective tobacco withdrawal.

Abstract
OBJECTIVE This double-blind, placebo controlled study examined whether menthol inhaled from an electronic cigarette (e-cigarette) would change subjective and withdrawal alleviating effects of intravenous nicotine in young adult smokers. METHODS A total of 32 menthol-preferring smokers and 25 non-menthol-preferring smokers participated in the study that consisted of a random sequence of three different inhaled menthol conditions (0.0%, 0.5%, and 3.2%) across three test sessions (a single menthol condition per session). In each test session (performed at least 24 hours apart), a random order of saline, and two different nicotine infusions of 0.25 mg and 0.5 mg/70 kg of bodyweight were administered, one hour apart, concurrent with menthol inhalation. RESULTS While menthol did not alter the positive subjective effects of nicotine, menthol significantly enhanced aversive effects of nicotine in non-menthol-preferring smokers and reduced smoking urges in menthol-preferring smokers. In addition, menthol-preferring smokers reported blunted positive subjective responses to nicotine and less severe nicotine withdrawal after overnight nicotine deprivation. Finally, compared to non-menthol-preferring smokers, menthol-preferring smokers had a significantly lower baseline nicotine metabolite ratio indicating slower nicotine metabolism within our sample of menthol-preferring smokers. CONCLUSIONS Our findings did not support an enhancement of nicotine's positive subjective effects from inhaled menthol. However, as compared to non-menthol-preferring smokers, menthol-preferring smokers had blunted positive subjective responses to nicotine and reduced overnight withdrawal severity that may be partly due to inhibition of nicotine metabolism from chronic exposure to inhaled menthol. Collectively, these results reveal a more complex and nuanced role of inhaled menthol in smokers than previously recognized.

Abstract
Objective The urge to smoke is a predictor of smoking relapse. Little research has focused on the impact of acute urges during treatment among African Americans. This study examined the relationship between smoking urges and long-term abstinence among treatment seekers. Design Longitudinal prospective investigation. Urges to smoke were assessed at the initial (session 1) and final (session 8) sessions among adult smokers (N=308) enrolled in a 4-week group intervention trial. Nicotine patch use was assessed over 30 days. Main Outcome Measures Biochemically verified 7-day point prevalence abstinence (7-day ppa) was assessed immediately post-intervention, and at 3-, 6-, and 12-month follow-ups. Hierarchical logistic regressions tested associations between session 1 and session 8 urges and 7-day ppa at each smoking status assessment. Results There was a significant overall decrease in smoking urges (M=29, SD=15 at session 1; M=17, SD=11 at session 8). After controlling for covariates, urges to smoke at session 1 were unrelated to 7-day ppa at any of the assessment points. However, session 8 urges were inversely associated with 7-day ppa post-intervention (AOR=.94, CI:.92-.97), at 3-months (AOR=.93, CI: .89-.97), 6-months (AOR=.93, CI: .90-.97), and 12-months (AOR=.96, CI: .96-.99). Nicotine patch use was positively associated with 7-day ppa at each assessment. Conclusions The most robust predictors of abstinence through 12-months post-intervention were decreased urges over the 4-week, 8-session group intervention and the frequency of nicotine patch use. Interventions aimed at addressing the needs of African American smokers should address urges and encourage nicotine replacement adherence to increase abstinence rates.

Racial/Ethnic Differences in Self-reported Withdrawal Symptoms and Quitting Smoking Three Years Later: A Prospective, Longitudinal Examination of US Adults. Nicotine Tob Res 2017; 19:373-378.

Abstract
Introduction Racial/ethnic groups appear to differ on quit success and withdrawal is a key factor in cessation failure, yet little is known about racial/ethnic differences in withdrawal symptoms. This study of US adults examined racial/ethnic differences in current smokers' report of withdrawal symptoms and the relationship between withdrawal symptoms and quitting smoking 3 years later. Methods Using data from the National Epidemiologic Survey on Alcohol and Related Conditions (Wave 1, 2001-2001; Wave 2, 2004-2005), analyses were conducted on participants who identified as non-Hispanic White, non-Hispanic Black, or Hispanic; reported current cigarette smoking at Wave 1; and provided smoking status information at Wave 2 (n = 7981). Withdrawal symptoms during past quit attempts were assessed at Wave 1. Results Among Wave 1 current smoking adults, non-Hispanic White respondents were more likely than non-Hispanic Black and Hispanic respondents to report experiencing at least one withdrawal symptom, seven out of eight withdrawal symptoms, withdrawal-related discomfort, and withdrawal-related distress (ps < .0001). While withdrawal symptoms were associated with a lower odds of quitting smoking for all groups, a stronger relationship between number of symptoms and lower odds of quitting was evident among non-Hispanic White compared to non-Hispanic Black respondents (interaction β = 0.065, p = .0001). For non-Hispanic White participants, each additional withdrawal symptom was associated with a 6% decrease in the odds of quitting. Conclusions Withdrawal symptoms were more commonly reported by non-Hispanic White adults than non-Hispanic Black and Hispanic adults and appeared to have a greater impact on failure to quit smoking for non-Hispanic White compared to non-Hispanic Black adults. Implications To our knowledge, this is the first study to use prospective, longitudinal data to examine the relationship between race and withdrawal symptoms and the impact of withdrawal symptoms on quitting smoking among adults in the United States. Non-Hispanic White adults were more likely to report withdrawal symptoms and there was a stronger relationship between greater number of withdrawal symptoms and lower odds of quitting for non-Hispanic White adults compared to non-Hispanic Black adults. Developing a better understanding of racial/ethnic differences in withdrawal and cessation can help to tailor efforts to improve outcomes for smokers in various racial/ethnic groups.

Abstract
Psychiatric hospitals are increasingly adopting smoke-free policies. Tobacco use is common among persons with mental illness, and nicotine withdrawal (NW), which includes symptoms of depression, anxiety, anger/irritability, and sleep disturbance, may confound psychiatric assessment and treatment in the inpatient setting. This study aimed to characterize NW and correlates of NW severity in a sample of smokers hospitalized for treatment of mental illness in California. Participants (N=754) were enrolled between 2009 and 2013, and averaged 17 (SD=10) cigarettes/day prior to hospitalization. Though most (70%) received nicotine replacement therapy (NRT) during hospitalization, a majority (65%) reported experiencing moderate to severe NW. In a general linear regression model, NW symptoms were more severe for women, African American patients, and polysubstance abusers. Though invariant by psychiatric diagnostic category, greater NW was associated with more severe overall psychopathology and greater cigarette dependence. The full model explained 46% of the total variation in NW symptom severity (F [19, 470]=23.03 p<0.001). A minority of participants (13%) refused NRT during hospitalization. Those who refused NRT reported milder cigarette dependence and stated no prior use of NRT. Among smokers hospitalized for mental illness, NW severity appears multidetermined, related to cigarette dependence, demographic variables, psychiatric symptom severity, and other substance use. Assessment and treatment of NW in the psychiatric hospital is clinically warranted and with extra attention to groups that may be more vulnerable or naïve to cessation pharmacotherapy.

Abstract
OBJECTIVE Evaluating electronic cigarettes (ECIGs) in the clinical laboratory is critical to understanding their effects. However, laboratory evaluation of ECIGs can be challenging, as they are a novel, varied, and evolving class of products. The objective of this paper is to describe some methodological challenges to the clinical laboratory evaluation of ECIGs. METHODS The authors gathered information about challenges involved in the laboratory evaluation of ECIGs. Challenges were categorized and solutions provided when possible. RESULTS Methods used to study combustible cigarettes may need to be adapted to account for ECIG novelty and differences within the class. Challenges to ECIG evaluation can include issues related to 1) identification of ECIG devices and liquids, 2) determination of short -term ECIG abstinence, 3) measurement of use behavior, and 4) assessment of dependence. These challenges are discussed, and some suggestions to inform ECIG evaluation using clinical laboratory methods are provided. CONCLUSIONS Awareness of challenges and developing, validating, and reporting methods used to address them aids interpretation of results and replication efforts, thus enhancing the rigor of science used to protect public health through appropriate, empirically-based, ECIG regulation.

Abstract
Efforts to reduce the public health burden of tobacco use have not equally benefited all members of society, leading to disparities in tobacco use as a function of ethnicity/race, socioeconomic position, physical/behavioral comorbidity, and other factors. Although multilevel transdisciplinary models are needed to comprehensively understand sources of tobacco-related health disparities (TRHD), the incorporation of psychopharmacology into TRHD research is rare. Similarly, psychopharmacology researchers have often overlooked the societal context in which tobacco is consumed. In an effort to facilitate transdisciplinary research agendas for studying TRHD and the psychopharmacology of tobacco use, this article introduces a novel paradigm, called "sociopharmacology." Sociopharmacology is a platform for investigating how contextual factors amplify psychopharmacological determinants of smoking to disproportionately enhance vulnerability to smoking in populations subject to TRHD. The overall goal of sociopharmacology is to identify proximal person-level psychopharmacological mechanisms that channel distal societal-level influences on TRHD. In this article I describe: (1) sociopharmacology's overarching methodology and theoretical framework; (2) example models that apply sociopharmacology to understand mechanisms underlying TRHD; (3) how sociopharmacological approaches may enhance the public health impact of basic research on the psychopharmacology of tobacco use; and (4) how understanding sociopharmacological mechanisms of TRHD might ultimately translate into interventions that reduce TRHD.

Abstract
Prenatal marijuana exposure (PME) is linked to neurobehavioral and cognitive impairments; however, findings in childhood and adolescence are inconsistent. Type-1 cannabinoid receptors (CB1R) modulate fetal neurodevelopment, mediating PME effects on growth of functional circuitry sub-serving behaviors critical for academic and social success. The purpose of this study was to investigate the effects of prenatal marijuana on development of early brain functional circuitry prior to prolonged postnatal environmental influences. We measured resting state functional connectivity during unsedated sleep in infants at 2–6 weeks (+MJ: 20 with PME in combination with nicotine, alcohol, opiates, and/or selective serotonin reuptake inhibitors; −MJ: 23 exposed to the same other drugs without marijuana, CTR: 20 drug-free controls). Connectivity of subcortical seed regions with high fetal CB1R expression was examined. Marijuana-specific differences were observed in insula and three striatal connections: anterior insula–cerebellum, right caudate–cerebellum, right caudate–right fusiform gyrus/inferior occipital, left caudate–cerebellum. +MJ neonates had hypo-connectivity in all clusters compared with −MJ and CTR groups. Altered striatal connectivity to areas involved in visual spatial and motor learning, attention, and in fine-tuning of motor outputs involved in movement and language production may contribute to neurobehavioral deficits reported in this at-risk group. Disrupted anterior insula connectivity may contribute to altered integration of interoceptive signals with salience estimates, motivation, decision-making, and later drug use. Compared with CTRs, both +MJ and −MJ groups demonstrated hyper-connectivity of left amygdala seed with orbital frontal cortex and hypo-connectivity of posterior thalamus seed with hippocampus, suggesting vulnerability to multiple drugs in these circuits.

Abstract
INTRODUCTION Persistent tobacco use among racial and ethnic minority populations in the United States is a critical public health concern. Yet, potential sources of racial/ethnic disparities in tobacco use remain unclear. The present study examined racial/ethnic differences in tobacco withdrawal-a clinically-relevant underpinning of tobacco use that has received sparse attention in the disparities literature-utilizing a controlled laboratory design. METHODS Daily smokers (non-Hispanic African American [n = 178], non-Hispanic white [n = 118], and Hispanic [n = 28]) attended two counterbalanced sessions (non-abstinent vs. 16-hour abstinent). At both sessions, self-report measures of urge, nicotine withdrawal, and affect were administered and performance on an objective behavioral task that assessed motivation to reinstate smoking was recorded. Abstinence-induced changes (abstinent scores vs. non-abstinent scores) were analyzed as a function of race/ethnicity. RESULTS Non-Hispanic African American smokers reported greater abstinence-induced declines in several positive affect states in comparison to other racial/ethnic groups. Relative to Hispanic smokers, non-Hispanic African American and non-Hispanic white smokers displayed larger abstinence-provoked increases in urges to smoke. No racial/ethnic differences were detected for a composite measure of nicotine withdrawal symptomatology, negative affect states, and motivation to reinstate smoking behavior. CONCLUSIONS These results suggest qualitative differences in the expression of some components of tobacco withdrawal across three racial/ethnic groups. This research helps shed light on bio-behavioral sources of tobacco-related health disparities, informs the application of smoking cessation interventions across racial/ethnic groups, and may ultimately aid the overall effort towards reducing the public health burden of tobacco addiction in minority populations. IMPLICATIONS The current study provides some initial evidence that there may be qualitative differences in the types of tobacco withdrawal symptoms experienced among non-Hispanic African American, Hispanic, and non-Hispanic white smokers. Extending this line of inquiry may elucidate mechanisms involved in tobacco-related health disparities and ultimately aid in reducing the public health burden of smoking in racial/ethnic minority populations.

Black Cigarette Smokers Report More Attention to Smoking Cues Than White Smokers: Implications for Smoking Cessation. Nicotine Tob Res 2015; 17:1022-8. [PMID: 26180228 PMCID: PMC4838045 DOI: 10.1093/ntr/ntu263] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2014] [Accepted: 11/27/2014] [Indexed: 11/14/2022]
Abstract
INTRODUCTION Black cigarette smokers have lower rates of smoking cessation compared with Whites. However, the mechanisms underlying these differences are not clear. Many Blacks live in communities saturated by tobacco advertisements. These cue-rich environments may undermine cessation attempts by provoking smoking. Moreover, attentional bias to smoking cues (attention capture by smoking cues) has been linked to lower cessation outcomes. Cessation attempts among Blacks may be compromised by attentional bias to smoking cues and a cue-rich environment. METHOD Attention to smoking cues in Black and White smokers was examined in 2 studies. In both studies, assessments were completed during 2 laboratory visits: a nonabstinent session and an abstinent session. In study 1, nontreatment-seeking smokers (99 Whites, 104 Blacks) completed the Subjective Attentional Bias Questionnaire (SABQ; a self-report measure of attention to cues) and the Smoking Stroop task (a reaction time measure of attentional bias to smoking cues). In study 2, 110 White and 74 Black treatment-seeking smokers completed these assessments and attempted to quit. RESULTS In study 1, Blacks reported higher ratings than Whites on the SABQ (p = .005). In study 2, Blacks also reported higher ratings than Whites on the SABQ (p = .003). In study 2, Blacks had lower biochemical-verified point prevalence abstinence than Whites, and the between-race difference in outcome was partially mediated by SABQ ratings. CONCLUSION Blacks reported greater attention to smoking cues than Whites, possibly due to between-race differences in environments. Greater attention to smoking cues may undermine cessation attempts.

[PMID: 25431372 DOI: 10.1093/ntr/ntu236] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2014] [Accepted: 10/25/2014] [Indexed: 11/14/2022]
Abstract
BACKGROUND The time to first cigarette of the day (TTFC) is a strong indicator of nicotine dependence behaviors such as nicotine uptake and quit success in young and older smokers. There are substantial differences in levels of nicotine dependence by race and ethnic group. METHODS Data from Wave III of the multiracial National Longitudinal Study of Adolescent Health were analyzed for young smokers between the ages of 21 and 28 (N = 1,425). Time to first cigarette data was compared between Hispanic, White, Black, Native American, and Asian smokers. RESULTS Black smokers were significantly more likely to smoke within 5min of waking than White, Hispanic, and Asian smokers. Lower personal income predicted smoking within 5min of waking for both White and Black smokers. For White smokers, increased number of cigarettes per day and increased years of smoking also predicted smoking within 5min of waking. The number of days smoked or number of cigarettes per day did not predict smoking within 5min of waking among smokers. CONCLUSIONS The higher prevalence of early TTFC among Blacks indicates increased nicotine and carcinogen exposure, and may help explain the increased lung cancer rates and failed cessation attempts among Black smokers. TTFC may be an important screening item, independent of cigarettes per day, for clinicians and interventions to identify those at highest risk for cessation failure and disease risk.
