Increasing cessation motivation and treatment engagement among smokers in pain: A pilot randomized controlled trial

Recent advances in the treatment of chronic pain and substance use disorders

Among people with substance use disorders (SUDs), chronic pain is among the most common comorbid chronic health conditions. Chronic pain increases risk for poor SUD treatment outcomes, including risk for overdose. Given rising overdose rates across North America, a renewed research focus has emerged to better understand the contribution and treatment of chronic pain in the context of an SUD. A significant portion of this research has focused on behavioral interventions given their safety and efficacy in treating both conditions separately. Therefore, this article will describe the recent advances in the treatment of chronic pain and SUD, including promising care delivery models and behavioral treatments. Areas for further study will also be reviewed.

Understanding cancer patients' desire to quit tobacco without assistance: A mixed-methods study

While many cancer patients who use tobacco try to quit post-diagnosis, some prefer to quit without using tobacco treatment, despite evidence against unassisted quit attempts. This study aimed to understand the rationale for some cancer patients' desire to quit tobacco without assistance. Thirty-five adult cancer patients who currently used tobacco and declined tobacco treatment because of the desire to quit unassisted provided data via a standardized questionnaire and a semi-structured interview. The sample was predominately White, non-Hispanic (85.71%) and female (68.57%). The most common cancer site was gynecological. Key themes that emerged from the interviews were: self-reliance, willpower, social norms, and negative attitudes toward tobacco treatment. The most frequently endorsed barrier to tobacco treatment was "I know others who have quit without tobacco treatment" (82.86%). This study with cancer patients identified affective, cognitive, and personality factors related to quitting unassisted, and social and systemic reasons to not use tobacco treatment.

Bidirectional relationships between pain and patterns of cannabis and tobacco use in a US nationally representative sample

ABSTRACT

One-fifth of US adults experience chronic pain, which is associated with increased tobacco and cannabis use. Although bidirectional relationships between tobacco and pain have been demonstrated, pathways between pain, cannabis use, and co-use of cannabis and tobacco are understudied. We aimed to estimate the effects of (1) substance use (exclusive and co-use of cannabis and tobacco) on later pain intensity, and (2) pain intensity on later substance use. Data were from 31,983 adults in biennial surveys (2015-2021) of the US nationally representative longitudinal Population Assessment of Tobacco and Health Study (n = 71,055 pairs of consecutive surveys; T1 and T2). Past-week pain intensity was dichotomized (≤4/10 no/low pain; >4/10 moderate/severe pain). Mutually exclusive substance use categories (past 30 days) were no cannabis/tobacco use; exclusive cannabis/tobacco use; and co-use. Logistic regression assessed whether T1 substance use affected moderate/severe pain at T2. Multinomial models assessed whether pain status at T1 affected substance use at T2. Compared with no cannabis/tobacco use at T1, co-use (OR: 2.29 [95% CI: 2.09-2.51]), exclusive tobacco use (2.00 [1.86-2.14]), and exclusive cannabis use (1.35 [1.13-1.61]) were all associated with moderate/severe pain at T2. Moderate/severe pain at T1 increased odds of co-use (2.43 [2.22-2.66]), exclusive tobacco (2.12 [1.98-2.28]), and exclusive cannabis use (1.46 [1.29-1.65]) compared with no cannabis/tobacco use at T2, and increased odds of co-use at T2 compared with exclusive cannabis/tobacco use. Findings demonstrated bidirectional relationships between pain and the exclusive use and co-use of cannabis and tobacco and indicate potential synergy in the co-use of cannabis and tobacco with respect to pain.

Psychological Therapies Used for the Reduction of Habitual Cigarette Smoking Cigarette Consumption: A Systematic Review

Globally, there are around 1.3 billion cigarette consumers, indicating it to be the second highest risk factor for early death and morbidity. Meanwhile, psychological therapy offers tools based on its different models and techniques, which can contribute to smoking cessation. In this context, this study gathers scientific evidence to identify psychological therapies that can be used to reduce cigarette consumption. A systematic review of controlled clinical studies was conducted, implementing the PRISMA methodology. Search queries were performed with terms extracted from MESH (Medical Subject Headings) and DECS (Descriptors in Health Sciences). Subsequently, the search was queried in the scientific databases of Medline/PubMed, Cochrane, Scopus, Science Direct, ProQuest, and PsycNet, with subsequent verification of methodological quality using the Joanna Briggs Institute checklists. The selected documents revealed that cognitive behavioral therapy prevails due to its use and effectiveness in seven publications (25%). The cognitive approach with mindfulness therapy is found in 4 publications (14%), the transtheoretical model with motivational therapy in 4 publications (14%), brief psychological therapy in 3 publications (10%), and the remaining 10 documents (37%) correspond with others. Intervention studies refer to cognitive behavioral therapy as the most used in reducing cigarette consumption; in terms of the duration of abstinence, scientific evidence shows beneficial effects with short-term reduction.

NSF DARE-transforming modeling in neurorehabilitation: a patient-in-the-loop framework

In 2023, the National Science Foundation (NSF) and the National Institute of Health (NIH) brought together engineers, scientists, and clinicians by sponsoring a conference on computational modelling in neurorehabiilitation. To facilitate multidisciplinary collaborations and improve patient care, in this perspective piece we identify where and how computational modelling can support neurorehabilitation. To address the where, we developed a patient-in-the-loop framework that uses multiple and/or continual measurements to update diagnostic and treatment model parameters, treatment type, and treatment prescription, with the goal of maximizing clinically-relevant functional outcomes. This patient-in-the-loop framework has several key features: (i) it includes diagnostic and treatment models, (ii) it is clinically-grounded with the International Classification of Functioning, Disability and Health (ICF) and patient involvement, (iii) it uses multiple or continual data measurements over time, and (iv) it is applicable to a range of neurological and neurodevelopmental conditions. To address the how, we identify state-of-the-art and highlight promising avenues of future research across the realms of sensorimotor adaptation, neuroplasticity, musculoskeletal, and sensory & pain computational modelling. We also discuss both the importance of and how to perform model validation, as well as challenges to overcome when implementing computational models within a clinical setting. The patient-in-the-loop approach offers a unifying framework to guide multidisciplinary collaboration between computational and clinical stakeholders in the field of neurorehabilitation.

Associations Between Alcohol and Cannabis Use and Pain Among College Student-Athletes

Background: Pain motivates alcohol and cannabis use, with evidence that pain catastrophizing (i.e., ruminative exaggeration of pain) mediates these associations. Student-athletes represent a unique population who engage in riskier substance use, experience more substance-related consequences, and are more likely to develop chronic pain compared to non-athletes. Objectives: This study examined relationships between pain, catastrophizing, alcohol and cannabis use and consequences. Student-athletes from two Division I universities (N = 549; 51% female) completed a cross-sectional survey. Moderated mediation tested the conditional indirect effect of pain catastrophizing on associations between pain and alcohol- and cannabis- use and consequences, separately, with sex moderating the a and b paths. Results: There was a significant direct effect between pain and alcohol-related consequences (b = 0.11, p = .008). Pain and pain catastrophizing were positively associated in all four models (bs = 0.68-0.72, ps <.001), and this relationship was stronger among female than male athletes. No other direct or conditional indirect effects were observed. Conclusions: Student-athletes experiencing pain report more alcohol-related consequences, and pain catastrophizing may be particularly relevant for student-athletes with greater pain. Future research should examine other factors proposed by theoretical models, such as negative affect, while focusing on athletes with more significant pain (e.g., injured athletes).

Alcohol use severity in relation to pain severity and interference among latinx adults with current pain who smoke cigarettes

Limited research has focused expressly on dual tobacco-alcohol use among the Latinx population. Latinx individuals who smoke represent a tobacco health disparities group and evince elevated rates of pain problems and symptoms. Prior research has consistently linked pain problems and severity to smoking and alcohol prevalence, maintenance, and behavior. Accordingly, the current study sought to build from the limited work that exists among Latinx persons who smoke and evaluate the role of alcohol use severity in terms of pain severity and interference. The current sample consisted of 228 adult Latinx daily cigarette smokers (Mage = 34.95 years; SD = 8.58; 39.0% female) who endorsed current pain. Results indicated that elevated alcohol use problems were associated with greater levels of pain severity (R2 = 0.06) and interference (R2 = 0.06). The present findings suggest that there may be utility in clinical screening for alcohol use problems among Latinx persons who smoke to offset pain problems among this high-risk group.

Longitudinal Associations Between Pain and Use of Cigarettes and E-cigarettes in the Population Assessment of Tobacco and Health (PATH) Study

INTRODUCTION

Pain has been implicated in the onset and maintenance of nicotine addiction, and there is initial cross-sectional evidence of covariation between pain and the use of cigarettes and e-cigarettes. The goals of the current study were to: (1)test pain severity as a predictor of initiating co-use of cigarettes and e-cigarettes, (2)examine longitudinal associations between pain and use/co-use of cigarettes and e-cigarettes, (3)generate the first prevalence rate data regarding cigarette and e-cigarette use as a function of pain, and (4)examine gender as a moderator of these associations.

AIMS AND METHODS

Data were drawn from Waves 1-4 of the Population Assessment of Tobacco and Health Study (2013-2018).

RESULTS

Among exclusive cigarette smokers at Wave 1 (n = 7719), pain severity was associated with a greater likelihood of and faster trajectory to initiating co-use of cigarettes and e-cigarettes (ps < .05). A significant pain × gender interaction (p < .05) revealed this prospective relationship was stronger among women. Among adult respondents who provided at least three waves of data (n = 24 255), greater Wave 1 pain severity was positively associated with e-cigarette use, cigarette smoking, and co-use of cigarettes and e-cigarettes at Waves 2, 3, and 4 (ps < .001). At Wave 4 (n = 33 822), adults with moderate or severe pain endorsed rates of e-cigarette and cigarette use almost two times greater versus no or low pain (ps < .001).

CONCLUSIONS

Collectively, these findings provide evidence that pain likely serves as an important candidate risk factor for the initiation and maintenance of cigarette and e-cigarette use.

IMPLICATIONS

This is the first prospective study to show that pain serves as an important risk factor for initiation and maintenance of cigarette and e-cigarette use over time. Weighted prevalence estimates further demonstrated that individuals with moderate or severe pain endorsed rates of cigarette and e-cigarette use and co-use approximately two times greater compared to those with no or low pain. These findings highlight a subpopulation of nicotine users more susceptible to greater healthcare burden, nicotine dependence, and physical impairment. Nicotine users with comorbid pain may benefit from integrated interventions that address pain in the context of cessation.

The Impact of Smoking on the Development and Severity of Chronic Pain

PURPOSE OF REVIEW

The purpose of this review is to examine the impact of smoking and its role on the development of chronic pain and provide a critical review of recent literature.

RECENT FINDINGS

Recent studies demonstrate the bidirectional and dependent relationship between smoking and chronic pain. Those who are in pain have a more difficult time in the cessation of smoking as well as an increased sensitivity to pain during abstinence, lower confidence, and higher relapse rates. The fear of pain and the anxiety and depression that abstinence causes results in a grim outcome for long-term cessation. The dependent nature between chronic pain and smoking is affected by numerous variables. Providers should consider a multiprong approach to treating chronic pain and targeting smoking cessation treatment by providing motivational therapy, nicotine replacement, and medication therapies to prevent relapse, and providing those who are more likely to relapse with a higher level of care.

Perceived pain and smoking interrelations among veterans with chronic pain enrolled in a smoking cessation trial

INTRODUCTION

The Pain and Smoking Inventory (PSI) measures patients' perceived interrelations of their pain and smoking behavior, and comprises three conceptually-distinct domains: smoking to cope with pain (PSI-Cope), pain as a motivator of smoking (PSI-Motivate), and pain as a barrier to cessation (PSI-Barrier). Associations between PSI scores and pain interference and self-efficacy to quit smoking, two measures that can affect cessation outcomes, remain unclear.

METHODS

Secondary analysis of baseline data from 371 Veterans with chronic pain (88% male, M  age = 60) enrolled in a randomized smoking cessation trial. We used sequential multivariate regression models to examine associations between the three PSI domains and pain interference/self-efficacy.

RESULTS

Of 371 Veterans who completed baseline surveys, 88% were male with median age 60 years. PSI-Motivate scores were positively associated with pain interference (B: 0.18, 95% CI: 0.02, 0.34). PSI-Barrier sub-scores were negatively associated with self-efficacy (B: -0.23, 95% CI:-0.36, -0.10).

CONCLUSION

Findings suggest that individuals who hold maladaptive perceptions of pain-smoking interrelations may be more likely to endorse higher pain interference and lower self-efficacy-two established predictors of cessation outcomes. Moreover, each PSI subscale demonstrated unique relationships with the dependent variables, and our results provided support for a three-factor structure. These findings further demonstrate that the PSI comprises three conceptually and empirically distinct domains; future research should evaluate the clinical utility of assessing each domain in relation to cessation outcomes.

Examining Sex Differences in Associations between Pain and Alcohol Use among College Student-Athletes

Background: College student-athletes are a high-risk population for both pain and alcohol use. Although a growing literature indicates that pain motivates alcohol consumption, no studies have tested associations between pain and alcohol in college student-athletes. Methods and Results: Among National Collegiate Athletic Association Division I student-athletes at a large public university (N = 65; 48% Female), nearly all student-athletes (97%) reported alcohol use and 65% reported pain due to an athletic injury. Pain intensity was positively associated with greater motivation to reduce drinking prior to receiving a brief alcohol intervention. Among females, pain intensity was associated with lower self-reported alcohol consumption. Among male athletes, pain-related interference was associated with greater alcohol-related problems and lower perceived ability to deal with alcohol-related situations. Conclusion: Results provide initial evidence that pain may be important to consider when addressing alcohol use among student-athletes.

Pain and smoking study (PASS): A comparative effectiveness trial of smoking cessation counseling for veterans with chronic pain

Introduction

Smoking is associated with greater pain intensity and pain-related functional interference in people with chronic pain. Interventions that teach smokers with chronic pain how to apply adaptive coping strategies to promote both smoking cessation and pain self-management may be effective.

Methods

The Pain and Smoking Study (PASS) is a randomized clinical trial of a telephone-delivered, cognitive behavioral intervention among Veterans with chronic pain who smoke cigarettes. PASS participants are randomized to a standard telephone counseling intervention that includes five sessions focusing on motivational interviewing, craving and relapse management, rewards, and nicotine replacement therapy versus the same components with the addition of a cognitive behavioral intervention for pain management. Participants are assessed at baseline, 6, and 12 months. The primary outcome is smoking cessation.

Results

The 371 participants are 88% male, a median age of 60 years old (range 24–82), and smoke a median of 15 cigarettes per day. Participants are mainly white (61%), unemployed (70%), 33% had a high school degree or less, and report their overall health as “Fair” (40%) to “Poor” (11%). Overall, pain was moderately high (mean pain intensity in past week = 5.2 (Standard Deviation (SD) = 1.6) and mean pain interference = 5.5 (SD = 2.2)). Pain-related anxiety was high (mean = 47.0 (SD = 22.2)) and self-efficacy was low (mean = 3.8 (SD = 1.6)).

Conclusions

PASS utilizes an innovative smoking and pain intervention to promote smoking cessation among Veterans with chronic pain. Baseline characteristics reflect a socioeconomically vulnerable population with a high burden of mental health comorbidities.

I smoke to cope with pain: patients' perspectives on the link between cigarette smoking and pain

BACKGROUND

For people with chronic pain, cigarette smoking is associated with greater pain intensity and impairment. Researchers have hypothesized a reciprocal relationship in which pain and smoking exacerbate each other, resulting in greater pain and increased smoking. This study aimed to qualitatively examine patient perspectives on this association.

METHODS

A retrospective thematic analysis of smoking cessation counseling notes for 136 veterans in the Pain and Smoking Study, a tailored smoking cessation trial, was conducted. A validated codebook was applied to each counseling note by four independent coders using Atlas.ti (Atlas.ti, Berlin, Germany). Coders participated in a consensus-forming exercise with salient themes validated among the wider research team.

KEY RESULTS

Participants averaged 60 years of age (range 28-77 years) and were 9% female. The median number of cigarettes smoked per day was 15, with a mean pain intensity score in the last week (from 0-10) of 5.1. While not all patients acknowledged a connection between pain and smoking, we found that (1) pain motivates smoking and helps manage pain-related distress, as a coping strategy and through cognitive distraction, and (2) pain motivates smoking but smoking does not offer pain relief. Concerns about managing pain without smoking was identified as a notable barrier to cessation.

CONCLUSION

Many patients with chronic pain who smoke readily identified pain as a motivator of their smoking behavior and are reluctant to quit for this reason. Integrated interventions for smokers with pain should address these perceptions and expectancies and promote uptake of more adaptive self-management strategies for pain.

Cognitive-Affective Transdiagnostic Factors Associated With Vulnerability to Alcohol and Prescription Opioid Use in the Context of Pain

The use of alcohol and prescription opioids is common among people in pain and poses significant public health burdens. This review identifies factors associated with motivation to use alcohol and prescription opioids in the context of pain. Pain-relevant, cognitive-affective, transdiagnostic vulnerability factors-expectancies/motives, pain catastrophizing, pain-related anxiety, distress intolerance, anxiety sensitivity, and perceived interrelations-were selected from theoretical conceptualizations of pain and substance use. Searches conducted in PubMed, PsycINFO, and Embase returned 25 studies that examined associations between identified variables of interest and the use of alcohol and prescription opioids in the context of pain. Consistent with a larger literature on pain and substance use, the studies included in this review demonstrated that people with chronic pain are motivated to use alcohol and opioids in response to negative affect and hold expectancies/motives for coping with pain. Vulnerabilities that engender difficulty managing aversive internal states (distress intolerance and anxiety sensitivity) and maladaptive responses to pain (pain-related anxiety and pain catastrophizing) also were implicated in motivation for alcohol and opioid use. Although one study found that pain-related anxiety was associated with co-use of alcohol and opioids, no studies examined simultaneous use. Future research directions that can explicate causal associations, identify patterns of alcohol and opioid co-use, clarify the role of pain in cessation processes, and inform treatment development are discussed.

Anxiety sensitivity, pain severity and co-use of cigarettes and e-cigarettes among adults with chronic pain

Anxiety sensitivity (fear of potential negative consequences of anxiety-related symptoms/sensations) has been identified as a transdiagnostic factor in comorbid pain and nicotine dependence and evidence suggests that anxiety sensitivity may be indirectly associated with nicotine use via greater pain severity. Therefore, this study tested the hypothesis that anxiety sensitivity is associated with cigarette and e-cigarette use/co-use directly and indirectly via greater pain severity. Participants included 273 online survey respondents with chronic musculoskeletal pain (34% female; Mage = 32.9). Anxiety sensitivity was positively associated with cigarette smoking, e-cigarette use and cigarette/e-cigarette co-use (ps < .05). Furthermore, anxiety sensitivity was indirectly and positively associated with cigarette smoking, e-cigarette use and co-use via greater chronic pain severity. Pain severity may play an important role in associations between anxiety sensitivity and nicotine dependence and prospective research should examine temporal/causal effects of anxiety sensitivity in relation to pain severity and nicotine/tobacco use.

Prevalence and impact of comorbid chronic pain and cigarette smoking among people living with HIV

Rates of chronic pain and cigarette smoking are each substantially higher among people living with HIV (PLWH) than in the general population. The goal of these analyses was to examine the prevalence and impact of comorbid chronic pain and cigarette smoking among PLWH. Participants included 3289 PLWH (83% male) who were recruited from five HIV clinics. As expected, the prevalence of smoking was higher among PLWH with chronic pain (41.9%), than PLWH without chronic pain (26.6%, p < .0001), and the prevalence of chronic pain was higher among current smokers (32.9%), than among former (23.6%) or never (17%) smokers (ps < .0001). PLWH who endorsed comorbid chronic pain and smoking (vs. nonsmokers without chronic pain) were more likely to report cocaine/crack and cannabis use, be prescribed long-term opioid therapy, and have virologic failure, even after controlling for relevant sociodemographic and substance-related variables (ps < .05). These results contribute to a growing empirical literature indicating that chronic pain and cigarette smoking frequently co-occur, and extend this work to a large sample of PLWH. Indeed, PLWH may benefit from interventions that are tailored to address bidirectional pain-smoking effects in the context of HIV.
