The prominence of smoking-related mortality among individuals with alcohol- or drug-use disorders

Associations between smoking and pain in early recovery in residential substance use treatment-seekers

INTRODUCTION

A growing literature indicates bidirectional associations between pain and tobacco use. Cigarette smokers are at increased risk for chronic pain, and observational and experimental studies indicate that pain increases motivation to smoke. Tobacco use disorder frequently co-occurs with other substance use disorders, which are also associated with chronic pain vulnerability. Despite evidence that pain significantly predicts smoking and relapse, associations between smoking history/trajectory and changes in pain over the course of treatment have not been characterized. The objective of the study was to determine the association between in-treatment smoking trajectory, pack-years (i.e., number of cigarette packs smoked per day multiplied by smoking duration), pain-related interference in daily activities, and pain intensity over the course of residential treatment.

METHODS

In this study, 280 adult smokers in a residential SUD treatment center in North Central Florida completed questionnaires assessing cigarette use, pain intensity, and pain interference at treatment entry and discharge (Mean = 80.3 days, SD = 25.6). Most participants were diagnosed with alcohol use disorder (66.1 %). Opioid (27.9 %) and cannabis use disorders (29.6 %) were also common. Participants were grouped by whether their smoking increased (n = 36), decreased (n = 46), or stayed the same (n = 133) from entry to discharge.

RESULTS

Analyses indicated a positive association between pack-years and pain intensity at both baseline (r = 0.185, p = 0.018) and discharge (r = 0.184, p = 0.019). Smoking trajectory was associated with pack-years, with those decreasing smoking having greater pack-years than those sustaining or increasing use [F(2,136) = 8.62, p < 0.01, η2p = 0.114]. Mixed general linear models indicated pain intensity [F(1,274) = 44.15, p < 0.0001, η2p = 0.138] and interference in day-to-day activities [F(1,276) = 31.79, p < 0.0001, η2p = 0.103] decreased significantly over time. However, there was no main effect of smoking trajectory on pain intensity [F(2,212) = 2.051, p = 0.131, η2p = 0.019] or of smoking trajectory by time interaction [F(2, 212) = 1.228, p = 0.295, η2p = 0.011].

CONCLUSIONS

Overall, findings provide evidence that smoking behavior influences pain within the context of residential substance use treatment. Given that pain is associated with urge to use substances and risk of return to use, more consistent and rigorous assessment of pain and proactive pain management is likely to enhance substance use treatment outcomes among people who smoke.

Challenges to smoking cessation in patients with substance use disorders

Despite significant progress in tobacco control measures and stringent smoking policies, cigarette smoking remains one of the largest preventable causes of death and disability worldwide. The World Health Organization estimates that over 8 million global deaths are attributed to smoking yearly, and in Singapore, more than 2,000 Singaporeans die prematurely due to smoking-related diseases each year.1,2

Policy and Practice Changes Associated with a Tobacco-Free Initiative in Residential Substance Use Disorder Treatment

A California-sponsored, 18-month, tobacco-free intervention in residential substance use disorder (SUD) programs was associated with increases in tobacco-free grounds and tobacco-related client services. The current study examined whether positive results would be replicated in 11 programs participating subsequently. Program directors (N = 11) completed surveys of tobacco-related policies pre- and post-intervention. Pre- (n = 163) and post-intervention (n = 128) cross-sectional staff surveys examined tobacco-related training, beliefs, practices, smoking policy, and smoking status. Directors reported increases in tobacco-free grounds (from 3 to 8 programs), tobacco-related staff training (1 to 10 programs), tobacco cessation staff services (1 to 9 programs) and nicotine replacement therapy (NRT) provision (6 to 10 programs). At post-intervention, staff were more likely to report smoke-free workplaces (p = 0.008), positive beliefs about treating tobacco use (p = 0.017) and less likely to report current smoking (p = 0.003). Clinical staff were more likely to report tobacco-related training receipt (p = 0.001), program-level NRT provision (p = 0.009) and conducting tobacco-related client services (p < 0.0001) post-intervention. Findings of increases in tobacco-free grounds and tobacco cessation client services corroborated prior results. These and the additional finding of decreases in staff smoking strengthen evidence that initiatives supporting tobacco-free policies can be successfully implemented in SUD treatment.

Smoking Behavior and Wellness among Individuals in Substance Use Disorder Treatment

Tobacco-related morbidity and mortality disproportionately affect people with substance use disorders (SUD). Encouraging overall wellness may support tobacco use cessation. We investigated relationships between wellness (health status, physical activity, sugar-sweetened beverage (SSB) consumption), cigarette smoking, and smoking cessation among SUD treatment patients to inform clinical care. Cross-sectional surveys were conducted with 395 patients in 20 California residential SUD programs. Using multivariate regression, we examined associations between smoking status and wellness. Among smokers, we examined associations between lifetime smoking exposure, cessation behaviors and attitudes, and wellness. Compared to nonsmokers (n = 121), smokers (n = 274) reported more SSB consumption, poorer physical health, and more respiratory symptoms. Among smokers, SSB consumption and respiratory symptoms increased per ten pack-years of smoking. Smokers with respiratory symptoms reported higher motivation to quit and more use of nicotine replacement therapy (NRT). Smokers with more days of poor mental health reported lower motivation to quit. Overall, cigarette smoking was associated with other health-risk behaviors among SUD treatment patients. Respiratory symptoms may increase, and poor mental health may decrease, SUD patients' intent to quit smoking. To reduce chronic disease risk among SUD patients, treatment programs should consider promoting overall wellness concurrently with smoking cessation.

Addressing nutrition and physical activity in substance use disorder treatment: Client reports from a wellness-oriented, tobacco-free policy intervention

Introduction

Interest in wellness interventions in substance use disorder (SUD) treatment is growing although evidence remains limited. This study evaluated nutrition, physical activity, nutrition and physical activity counseling, and relationships of counseling with wellness behavior before and after a wellness-oriented, tobacco-free policy intervention in 17 residential SUD programs.

Methods

Clients completed cross-sectional surveys reporting sugar-sweetened beverage consumption, physical activity, and receipt of nutrition and physical activity counseling before (n= 434) and after (n = 422) an 18-month intervention. Multivariable regression models assessed pre-post-intervention differences in these variables and examined associations of nutrition counseling with sugar-sweetened beverage consumption and physical activity counseling with physical activity.

Results

Post-intervention clients were 83% more likely than pre-intervention clients to report nutrition counseling (p = 0.024). There were no pre-post- differences for other variables. Past week sugar-sweetened beverage consumption was 22% lower among clients reporting nutrition counseling than for those who did not (p = 0.008) and this association did not vary by time (pre/post). There was a significant interaction of physical activity counseling receipt by time on past week physical activity (p = 0.008). Pre-intervention clients reporting physical activity counseling had 22% higher physical activity than those who did not; post-intervention clients reporting physical activity counseling had 47% higher physical activity.

Conclusion

A wellness policy intervention was associated with increased nutrition counseling. Nutrition counseling predicted lower sugar-sweetened beverage consumption. Physical activity counseling predicted higher physical activity, an association that was greater post-intervention. Adding wellness components to tobacco-related interventions may promote health among SUD clients.

Influence of Provider and Leader Perspectives about Concurrent Tobacco-Use Care during Substance-Use Treatment on Their Tobacco Intervention Provision with Clients: A Mixed-Methods Study

People with substance-use disorders have elevated rates of tobacco use compared with the general population, yet rarely receive tobacco-dependence treatment within substance-use treatment settings (SUTS). One barrier to delivering evidence-based interventions in SUTS is providers' misconception that treating tobacco use and non-nicotine substance use concurrently jeopardizes clients' substance-use recovery, although research indicates that it enhances support for recovery and relapse prevention. A total of 86 treatment providers employed in SUTS (i.e., 9 Federally Qualified Health Centers, 16 Local Mental Health Authorities (LMHAs), 6 substance-use treatment programs in LMHAs, and 55 stand-alone substance-use treatment centers) in Texas, USA, answered survey questions about their (1) thoughts about treating tobacco during substance-use treatment, and (2) delivery of the 5A's tobacco-use intervention (Ask, Advise, Assess, Assist, Arrange). Twenty-six providers and leaders were interviewed about attitudes toward tobacco-free workplace policies and tobacco dependence and the relative importance of treating tobacco (vs. other substance-use disorders) at their center. Providers who did not believe tobacco use should be addressed as soon as clients begin treatment (i.e., endorsed responses of after 1 year, it depends on the client, or never) had lower odds of Asking clients about their tobacco use (OR = 0.195), Advising clients to quit smoking (OR = 0.176), and Assessing interest in quitting smoking (OR = 0.322). Qualitative results revealed barriers including beliefs that clients need to smoke to relieve the stress of substance-use recovery, are disinterested in quitting, fears that concurrent treatment would jeopardize substance use, and limited resources; additional training and education resources was the key facilitator theme. The results demonstrate a critical need to eliminate barriers to tobacco-treatment provision for clients in SUTS through education to correct misperceptions, specialized training to equip providers with knowledge and skills, and resources to build center capacity. Integrating evidence-based smoking interventions into routine care is key to support the recovery efforts of clients in SUTS.

Patient experiences with tobacco use during substance use disorder treatment and early recovery: a mixed method analysis of phone interview responses

Tobacco use and related mortality remain disproportionately high among individuals with substance use disorders (SUDs). Though engagement in tobacco cessation interventions is associated with improved long-term recovery, many individuals in SUD treatment do not participate. The goal of the present study was to better understand patient views regarding tobacco use/cessation during residential SUD treatment, in order to decrease barriers for this vulnerable population. This study utilized a cross-sectional design and mixed methods analysis. Following discharge from residential SUD treatment, individuals who reported any use of tobacco were invited to participate in a brief phone interview. Forty-one of the 60 who were reached (68%) agreed to participate. Responses were quantified for analysis when appropriate, and descriptive statistics were calculated for quantitative data. Thematic analysis was used to analyze qualitative responses. Most respondents (83%) reported that tobacco cessation was an important goal and were open to tobacco cessation treatment. The vast majority (85%) did not think tobacco use interfered with their recovery from other SUDs. Respondents noted the socially-reinforcing nature of tobacco use in treatment, and indicated a desire for increased access to cessation services. Results suggest increased patient education and changes to treatment center tobacco policies may assist individuals recovering from SUD with tobacco cessation.

Collaborative Learning: A Qualitative Study Exploring Factors Contributing to a Successful Tobacco Cessation Train-the-Trainer Program as a Community of Practice

Individuals with behavioral health conditions account for 50% of annual smoking-related deaths, yet rarely receive tobacco dependence treatment within local mental health authorities (LMHAs). As lack of training and knowledge are key barriers to providing tobacco dependence treatment, Taking Texas Tobacco-Free (TTTF) developed an iterative, 4-6-months train-the-trainer program to embed expertise and delivery of sustained education on tobacco-free workplace policies and practices in participating centers. We explore the employee "champions'" train-the-trainer program experiences using a community of practice (CoP) model to identify key contributors to successful program implementation. Across 3 different LMHAs, we conducted semi-structured individual and group interviews online at 2 time points. We interviewed each champion twice (except for 1 champion who dropped out between measurements); pre-implementation (3 group interviews; N = 4 + 4 + 3 = 11 champions); post-implementation (7 individual interviews and 1 group interview; 7 + 3 = 10 champions). Therefore, 11 champions participated in pre- and post-implementation interviews from July 2020-May 2021. Guided by an iterative, thematic analysis and constant comparison process, we inductively coded and summarized data into themes. Five factors contributed to successful program implementation: value of peer support/feedback; building knowledge, champion confidence, and program ownership; informative curriculum, adaptable to targeted populations; staying abreast of current tobacco/nicotine research and products; and TTTF team responsiveness and practical coaching/assistance. Champions reported the TTTF train-the-trainer program was successful and identified attitudes and CoP processes that effectively built organizational capacity and expertise to sustainably address tobacco dependence. Study findings can guide other agencies in implementing sustainable tobacco-free training programs.

Effect of substance use on premature mortality among severely hypertensive African Americans

Low‐income African Americans residing in impoverished neighborhoods confront myriad barriers to adhering to antihypertensive regimens. Substance use may thwart medication adherence and lifestyle modification efforts, which has implications for excess cardiovascular disease mortality. The Inner‐City Hypertension and Body Organ Damage (ICHABOD) Study was a longitudinal cohort study that evaluated causes of mortality among African Americans who lived in urban areas, had severe, poorly controlled hypertension, and were admitted to a local hospital between 1999–2001 and 2002–2004. The authors employed Cox proportional hazards models to assess mortality associated with illicit substance use, including use of heroin and cocaine, as well as by use of tobacco and alcohol. Among192 participants with poorly controlled hypertension, 30% were active illicit substance users (specifically, 22.7% heroin users, 19.8% were cocaine users, and 30.7% were both cocaine and heroin users). The mean age among substance non‐users was 52.3 years versus 48.7 years among those reporting current use. Mortality over 7.6 years of follow‐up was 52.5% among substance users and 33.8% among nonusers (p‐value, 0.01). After adjusting for potential confounders, the hazard ratio (HR) for cocaine use was 2.52 (95% confidence interval (CI) 1.38–4.59), while the HR for heroin use was 2.47 (95% CI 1.42–4.28) and the HR for both was 2.75 (95% CI 1.60–4.73). Substance use was associated with increased mortality among urban black Americans with poorly controlled hypertension. These data suggest the need for targeted interventions to support African Americans who have poorly controlled hypertension and use illicit substances, as a means of reducing excess mortality.

Implementing tobacco-free policy in residential substance use disorders treatment: Practice changes among staff

Introduction

Implementing tobacco-free policies in substance use disorders (SUD) treatment may reduce tobacco-related, health disparities. This study examined adoption of tobacco-related policy and practices in six residential programs participating in a California-sponsored, 18-month, tobacco-free policy intervention.

Methods

Directors (N=6) completed surveys of tobacco-related policies before and after the intervention. Staff completed cross-sectional surveys assessing tobacco-related training, beliefs, practices, workplace smoking policy, tobacco cessation program services, and smoking status pre- (n=135) and post-intervention (n=144).

Results

Director surveys indicated no programs had tobacco-free grounds, one provided tobacco-related staff training, and two provided nicotine replacement therapy (NRT) pre-intervention. At post-intervention, 5 programs had implemented tobacco-free grounds, 6 provided tobacco cessation training, and 3 provided NRT. Across all programs, staff were more likely to report smoke-free workplaces (AOR = 5.76, 95% CI1.14,29.18) post- versus pre-intervention. Staff positive beliefs towards addressing tobacco use were higher post-intervention (p<0.001). Odds of clinical staff reporting tobacco-related training participation (AOR = 19.63, 95% CI14.21,27.13) and program-level provision of NRT (AOR = 4.01, 95% CI 1.54, 10.43) increased post- versus pre-intervention. Clinical staff reporting they provided tobacco cessation services were also higher post-intervention (p= 0.045). There were no changes in smoking prevalence or quit intention among smoking staff.

Conclusion

A tobacco-free policy intervention in SUD treatment was associated with implementation of tobacco-free grounds, tobacco-related training among staff, more positive staff beliefs towards and delivery of tobacco cessation services to clients. The model may be improved with greater emphasis on staff policy awareness, facilitating availability of NRT, and reducing staff smoking.

Pilot Cohorts for Development of Concurrent Mobile Treatment for Alcohol and Tobacco Use Disorders

Alcohol and tobacco are the 2 most frequently used drugs in the United States and represent the highest co-occurrence of polysubstance use. The objective of this study was to refine an intervention combining mobile contingency management with cognitive-behavioral telephone counseling for concurrent treatment of alcohol and tobacco use disorders. Two cohorts (n = 13 total, n = 5 women) of participants were enrolled, with 10/13 completing treatment and 7/13 completing the 6-month follow-up. At enrollment, participants were drinking a mean of 28.9 drinks per week (SD = 14.1), with a mean of 14.7 heavy drinking days in the past month (SD = 9.9), and a mean of 18.1 cigarettes per day (SD = 11.7). Treatment included a mobile application that participants used to record carbon monoxide and breath alcohol content readings to bioverify abstinence. Participants received up to 4 sessions of phone cognitive-behavioral therapy and monetary reinforcement contingent on abstinence. In cohort 1, 4/6 participants reported abstinent or low-risk drinking post-monitoring. Six weeks post quit-date, 2/6 participants were CO-bioverified abstinent from tobacco use, with 2/6 in dual remission. These results were maintained at 6-months. In cohort 2, 6/7 reported abstinent or low-risk drinking post-monitoring, 5 weeks post quit-date. At the post-monitoring visit, 5/7 were CO-bioverified abstinent from smoking, with 5/7 in dual remission. At 6-months, 3/7 reporting abstinent or low-risk drinking, 1/7 had bioverified abstinence from smoking, with 1/7 in dual remission. Observations suggest that it is possible to develop a concurrent mobile treatment for alcohol and tobacco use disorders.

No evidence of the clinical utility of single-item breakpoint to inform on tobacco demand in persons with substance use disorders

RATIONALE

Behavioral economics has shown that single-item demand indicators are promising for capturing crucial aspects of nicotine reinforcement. It is suggested that brief breakpoint measures perform comparably to full-length demand indices in characterizing nicotine dependence; however, there have been no thorough assessments of their validity in clinical settings.

OBJECTIVES

This study aimed to assess the validity and accuracy of a single-item breakpoint in informing on tobacco demand.

METHODS

The sample consisted of 88 treatment-seeking smokers (% males = 70.5%) enrolled in substance use treatment. Participants provided data on smoking characteristics and completed the Fagerström Test for Nicotine Dependence, a single-item breakpoint measure and a 14-item cigarette purchase task (CPT). Hierarchical regressions were performed to compare the predictive capability of a single-item breakpoint and full-length tobacco demand indicators in determining nicotine addiction severity.

RESULTS

The single-item breakpoint was significantly correlated with all indices stemmed from the CPT and both latent factors (all r values = .250-.368). Neither the brief breakpoint nor the full-length breakpoint significantly predicted nicotine dependence. After controlling for sex and smoking variables, factor 2 [β = .565, p < .001] and its observed variables Omax [β = .279, p = .006], 1/elasticity [β = .340, p = .001], and intensity [β = .551, p < .001], robustly predicted nicotine dependence severity.

CONCLUSIONS

Our findings do not support the validity of single-item breakpoint measures for characterizing nicotine dependence in substance users. In a bid to foster translational research, brief demand measures capturing Omax, intensity, and elasticity should be developed.

Reciprocal influences of tobacco use on illicit opioid and alcohol use during the first six-months of specialist addiction treatment

BACKGROUND

This is the first national study of lagged reciprocal associations between tobacco smoking frequency and change in illicit opioid or alcohol use frequency within six-months of treatment.

METHODS

All adults admitted to publicly-funded specialist addiction treatment in England in 2018/19 and enrolled for at least six months for either opioid use disorder (OUD; n = 22,046; 82.4 % of those eligible) or alcohol use disorder (AUD; n = 15,251; 78.8 % of those eligible). Two cross-lagged panel models estimated, separately for OUD and AUD patients, the relationships between smoking at admission and change in main drug over six months, and between main drug use at admission and change in smoking over six months.

RESULTS

Within the OUD cohort, illicit opioid use frequency reduced from 17.7 days to 8.0 days and smoking tobacco remained at 18.8 days. After controlling for available covariates, higher smoking frequency at admission was associated with a relative increase in illicit opioid use at six-months (0.02 days [95 % CI 0.00-0.03]). Within the AUD cohort, alcohol use frequency reduced from 21.2 days to 14.4 days while smoking tobacco reduced from 12.6 days to 11.5 days. Higher smoking frequency at admission was associated with a relative increase in alcohol use at six-months (0.03 days [95 % CI 0.02-0.04]) and higher alcohol use frequency at admission was associated with a relative increase in smoking at six-months (0.04 [95 % CI 0.02-0.06]), controlling for available covariates.

CONCLUSIONS

Higher smoking frequency at admission is associated with higher illicit opioid and alcohol use frequency after six-months of specialist addiction treatment.

Would You Be Surprised If This Patient Died This Year? Advance Care Planning in Substance Use Disorders

Primary care physicians are increasingly incorporating screening tools for substance use disorders (SUDs) and referral to treatment into their practice. Despite efforts to provide access to treatment, patients with SUDs remain at an increased risk of mortality, both from overdose and from general medical conditions. Advance care planning (ACP) is recommended for patients with chronic, progressive medical conditions such as malignancies or heart failure. Though SUDs are widely acknowledged to be chronic diseases associated with an increased risk of mortality, there has been little discussion on ACP in this population. ACP is a discussion regarding future care, often including selection of a surrogate decision-maker and completion of an advanced directive. ACP has been associated with better quality of end-of-life and care more consistent with patient preferences. Studies in other vulnerable populations have shown that marginalized and high-risk individuals may be less likely to receive ACP. Similarly, patients with SUDs may employ different decision-makers than that defined by law (i.e., friend vs. family member), increasing the importance of discussing patient values and social structure. Physicians should routinely conduct ACP conversations with patients with SUDs, especially those with chronic, progressive medical conditions and/or severe, uncontrolled substance use disorders.

Smoking related outcomes before and after implementation of tobacco-free grounds in residential substance use disorder treatment programs

BACKGROUND

This study examined the impact of a tobacco-free grounds (TFG) policy and the California $2.00/pack tobacco tax increase on tobacco use among individuals in residential substance use disorder (SUD) treatment.

METHODS

We conducted three cross-sectional surveys of clients enrolled in three residential SUD treatment programs. Wave 1 (Pre-TFG) included 190 clients, wave 2 (post-TFG and pre-tax increase) included 200 clients, and wave 3 (post-tax increase) included 201 clients. Demographic and tobacco-use characteristics were first compared between waves using bivariate comparisons. Regression models were used to compare each outcome with survey wave as the predictor, while adjusting for demographic characteristics and nesting of participants within programs.

RESULTS

Odds of clients being current smokers was lower (AOR = 0.43, 95%CI = 0.30,0.60) after implementation of TFG compared to baseline. Adjusted mean ratio (AMR) for cigarettes per day was lower post-TFG compared to baseline (AMR = 0.70, CI = 0.59, 0.83). There were no differences, across waves, in tobacco-related knowledge, attitudes, or services received by program clients, or use of nicotine replacement therapy. Increased cigarette taxation was not associated with reductions in client smoking.

CONCLUSION

Implementation of a TFG policy was associated with a lower prevalence of client smoking among individuals in residential SUD treatment. Increased state cigarette excise taxes were not associated with a further reduction in client smoking in the presence of TFG policies, though this may have been confounded by relaxing of the TFG policy. SUD treatment programs should promote TFG policies and increase tobacco cessation services for clients.

Multimethod Formative Research to Improve the Training and Delivery of Tobacco-cessation Interventions in Behavioral Health Settings

INTRODUCTION

Despite progress in reducing tobacco use within the general population, high prevalence of tobacco use continues in individuals with mental health and substance use disorders ("clients"). Tobacco use persists as the leading cause of premature mortality in this population. While behavioral health providers have frequent contacts with this population, they lack training in tobacco cessation counseling.

METHODS

We conducted multimethod formative data collection consisting of key informant interviews with providers, field observations at clinical sites, and structured group interviews with behavioral health providers, and, separately, clients. Activities were conducted at 4 behavioral health agencies with 9 behavioral health clinic sites in southern Arizona. Recurring phrases and level of repetition were quantified to identify themes. These themes were then used to adapt the method of training delivery and revise the curriculum content for providers at the participating sites.

RESULTS

Results indicated that providers had "training fatigue" and low satisfaction with multiple, online trainings. Further, providers noted issues including time constraints, competing clinical priorities, and low access to tobacco-cessation materials. Clients demonstrated high self-awareness around the importance of quitting smoking and professed frustration at being unable to quit, despite multiple attempts. Finally, both providers and clients agreed that a personal, supportive approach to cessation counseling was preferred.

CONCLUSIONS

Using results from this formative research to revise delivery and content of existing smoking-cessation training for behavioral health providers may address barriers to assisting clients with smoking cessation. Additional research to determine the efficacy of the adapted training is needed.

Speed kills: Associations between methamphetamine use, HIV infection, tobacco use, and accelerated mortality among gay and bisexual men in Los Angeles, CA 20years after methamphetamine dependence treatment

BACKGROUND

To better characterize mortality among methamphetamine users, we estimated rates of all-cause mortality by HIV serostatus and smoking history in gay and bisexual men (GBM) treated for methamphetamine dependence, and explored associated clinical and socio-behavioral characteristics.

METHODS

We searched public records to identify deaths among men screened between 1998-2000 for a trial of outpatient therapy for GBM with methamphetamine dependence. Crude mortality rates (CMRs) were calculated, and standardized mortality ratios (SMRs) estimated, comparing data with historical information from CDC WONDER. Associations of mortality with HIV infection, tobacco use, and other factors were explored using Kaplan-Meier survival analysis and Cox proportional hazards models.

RESULTS

Of 191 methamphetamine-dependent GBM (median age 35 years; majority Caucasian), 62.8% had HIV infection, and 31.4% smoked tobacco at baseline. During the 20-year follow-up period, 12.6% died. Relative to controls, methamphetamine-dependent GBM had a three-fold higher 20-year SMR: 3.39, 95% CI: 2.69-4.09. Especially high mortality was observed among participants reporting tobacco use (adjusted HR 3.48, 95% CI: 1.54-7.89), club drug use prior to starting methamphetamine (2.63, 1.15-6.00), or other clinical diagnoses at baseline (3.89, 1.15-13.22). At 20 years, the CMR for HIV infected participants (7.7 per 1000 PY) was 1.5 times that for men without HIV (5.2 per 1000 PY; p = 0.22) and there was a 5-fold difference in CMRs for HIV infected tobacco smokers (16.9 per 1000 PY) compared to non-smokers (3.4 per 1000 PY; p < 0.01).

CONCLUSION

In our sample of methamphetamine-dependent GBM, concomitant HIV infection and tobacco use were associated with dramatic increases in mortality.

Effectiveness of a telephone-based intervention for smoking cessation in patients with severe mental disorders: study protocol for a randomized controlled trial

Background

Up to 75% of inpatients with mental disorders smoke, and their life expectancy is decreased by up to 25 years compared to the general population. Hospitalized patients without monitoring after discharge quickly return to prehospitalization levels of tobacco use. The aim of the 061 QuitMental study is to assess the effectiveness of a multicomponent and motivational telephone-based intervention to stop smoking through a quitline addressed to smokers discharged from mental health hospital wards.

Methods

A pragmatic randomized controlled trial, single blinded, will include 2:1 allocation to the intervention group (IG) and the control group (CG). The IG will receive telephone assistance to quit smoking (including psychological and psychoeducational support, and pharmacological treatment advice if required) proactively for 12 months, and the CG will receive only brief advice after discharge. The sample size, calculated with an expected difference of 15 points on smoking abstinence between groups (IG, 20% and CG, 5%), α = 0.05, β = 0.10, and 20% loss, will be 334 participants (IG) and 176 participants (CG). Participants are adult smokers discharged from psychiatric units of five acute hospitals.

Measurements include dependent variables (self-reported 7-day point prevalence smoking abstinence (carbon monoxide verified), duration of abstinence, number of quit attempts, motivation, and self-efficacy to quit) and independent variables (age, sex, and psychiatric diagnoses). In data analysis, IG and CG data will be compared at 48 h and 1, 6, and 12 months post discharge. Multivariate logistic regression (odds ratio; 95% confidence interval) of dependent variables adjusted for potential confounding variables will be performed. The number needed to treat to achieve one abstinence outcome will be calculated. We will compare the abstinence rate of enrolled patients between groups.

Discussion

This trial evaluates an innovative format of a quitline for smokers with severe mental disorders regardless of their motivation to quit. If effective, the pragmatic nature of the study will permit transfer to routine clinical practice in the National Health System.

The association between nicotine dependence and physical health among people receiving injectable diacetylmorphine or hydromorphone for the treatment of chronic opioid use disorder

INTRODUCTION

People with chronic opioid use disorder often present to treatment with individual and structural vulnerabilities and remain at risk of reporting adverse health outcomes. This risk is greatly compounded by tobacco smoking, which is highly prevalent among people with chronic opioid use disorder. Despite the known burden of tobacco smoking on health, the relationship between nicotine dependence and health has not been studied among those receiving injectable opioid agonist treatment. As such, the present study aims to explore the association between nicotine dependence and physical health among participants of the Study to Assess Longer-Term Opioid Medication Effectiveness (SALOME) at baseline and six-months.

METHODS

SALOME was a double-blind phase III clinical trial testing the non-inferiority of injectable hydromorphone to injectable diacetylmorphine for chronic opioid use disorder. Participants reporting tobacco smoking were included in a linear regression analysis of physical health at baseline (before receiving treatment) and at six-months.

RESULTS

At baseline, nicotine dependence score, lifetime history of emotional, physical, or sexual abuse and prior month safe injection site access were independently and significantly associated with physical health. At six-months nicotine dependence score was the only variable that maintained this significant and independent association with physical health.

CONCLUSIONS

Findings indicate that after six-months, the injectable treatment effectively brought equity to patients' physical health status, yet the association with nicotine dependence remained. Findings could inform whether the provision of treatment for nicotine dependence should be made a priority in settings where injectable opioid agonist treatment is delivered to achieve improvements in overall physical health in this population.

Cigarette smoking and quit attempts among Latinos in substance use disorder treatment

BACKGROUND

Differences in tobacco use behaviors have been identified between Latinos and non-Latino whites in the general US population. Little is known about cigarette smoking and quitting behaviors of Latinos in treatment for substance use disorders (SUDs), who represent two major tobacco-vulnerable groups.

OBJECTIVES

To compare, in a national sample of persons enrolled in SUD treatment, demographic, drug use, and smoking and quitting prevalence and behaviors between Latinos and non-Latino whites.

METHODS

We surveyed 777 SUD treatment clients, sampled from 24 clinics selected at random from the National Institute on Drug Abuse Clinical Trials Network (Latino client n = 141; 40% female). We then conducted univariate and multivariate analyses to identify correlates of smoking behaviors by Latino/non-Latino white ethnicity.

RESULTS

Latinos' smoking prevalence resembled that of non-Latino whites (78.7% vs. 77.4%). In regression analyses, Latino smokers (n = 111) tended to smoke fewer cigarettes per day (CPD) than non-Latino white smokers (n = 492); were more often nondaily smokers and menthol smokers; more often reported a smoking quit attempt in the last year; and tended to report higher numbers of past-year quit attempts. Among Latino smokers, those with less education and those reporting opioids as their primary drug of use reported higher CPD.

CONCLUSIONS

Latinos in SUD treatment are at equally high risk of being current heavy smokers as compared to non-Latino whites in SUD treatment. At the same time, Latinos in SUD treatment exhibit ethnic-specific smoking and quitting behaviors that should be considered when designing smoking interventions for this group.
