In February 2021, Oregon became the first US state to decriminalize possession of small amounts of all commonly used illicit drugs (Measure 110); twenty-four days later, Washington's Supreme Court Blake ruling produced a weaker, shorter-lived decriminalization. Evaluations of these policy periods have focused on overdose deaths, with contested results; their association with the mental health of the general population is unknown. Using surveillance data on 6.3 million adult interviews (2011-2024) and synthetic control methods with permutation inference, we find frequent mental distress an estimated 2.15 percentage points higher in Oregon than in its synthetic counterfactual (largest positive gap among 45 jurisdictions; two-sided rank 2/45, p = 0.044, though not significant under the alternative fit-normalized statistic), with directionally consistent estimates in Washington and a joint test on the pair at p = 0.015. The increase concentrates in self-reported distress, among women and young adults, and is not mirrored in diagnoses, police-recorded partner violence or suicide.

Introduction Smoking prevalence remains higher in rural than in urban populations in the United States. To examine recent trends, we assessed state-level differences in cigarette smoking between urban and rural areas from 2018 to 2024. Methods Using repeated cross-sectional data from the Behavioral Risk Factor Surveillance System, we estimated state-specific logistic regression models to examine the relationship between urban-rural county residence and cigarette smoking. Unadjusted models (model 1) included urban-rural county status and year. Subsequent models (model 2) added age, sex, and race/ethnicity. A final model (model 3) included education and an interaction term between urban-rural county status and year to examine whether gaps in urban-rural smoking changed over time. In states with significant interactions, simple effects tests compared trends for urban-rural groups separately. Results Compared to urban adults, rural adults had higher unadjusted odds of cigarette smoking (odds ratio [OR] range:1.07-1.88) in 88.4% (38/43) of states. Adjusting for demographic covariates (model 2) increased the proportion of states with significant marginal effects of rurality to 90.7% (ORs:1.09-1.87). A final model that also controlled for education (model 3) decreased the proportion of states with significant marginal effects of rurality to 60.5% (ORs:1.10-1.54). Among the 14 states with significant interaction terms, the odds of smoking declined faster among urban than rural residents. Conclusion Urban-rural differences in smoking persist across most states. No state showed a reduction in urban-rural disparities over time, and the urban-rural gap widened in 14 states. Demographic variation accounted for some, but not the majority, of observed urban-rural differences.

Introduction: Research has documented that obesity and morbidity are associated. Black persons in the United States (U.S.) incur higher financial costs of obesity-related multimorbidity (ORM). However, lifetime healthcare costs (LHCs) remain underexamined for these populations. Objective: We quantified racial differences in 1) LHCs and 2) lifetime healthcare cost differential (LCD) associated with ORM for ages > 40 years. Methods: We used the 2008- 2012 Medical Expenditure Panel Survey Household Component to examine unique obesity-related diseases (ORDs): high blood sugar, hypertension, coronary heart disease, and stroke. We used a prior published Markov model to simulate a person's life history of ORDs and compute LHCs among ages > 40 years. We computed LCD-associated ORM as the difference in LHC for those with ORM and LHC for members without ORDs. We quantified differences in race as the difference between LHC or LCD among White and Black men and women. Results: Our analytic sample included 53,035 Black and White persons representing 97,229,611 (S.E., 2,104,365), 12.4% as Black and 87.6% as White persons. ORM was more prevalent in the Black (21.2%) than the White group (13.4%). LHCs by race (Black/White) for women/men with ORM and LCDs associated with ORM (2012$) were $3 1,035/43,595 and $11,350/26,948 for age 40-49, $2 1,567/25,6 115 and $3,846/9,808 for 50-59, $9,863/18,515 and -$2,566/7,426 for 60-69, -$8,220/16,285 and -$11,524/3,865 for 70-79. Conclusions: Racial Differences in LHCs and LCDs related to ORM persist and vary across subpopulations. Future interventions designed to prevent/manage ORM are crucial for prioritizing populations with high LHCs and advancing health equity.

Background: People with disabilities (PWD) represent over one-quarter of the US population and disproportionately experience chronic pain, yet limited research explores disparities they face in opioid use disorder (OUD) treatment. Objective: To examine disparities across disability status regarding opioid use disorder (OUD)-related outcomes and understand how chronic pain interacts with these associations. Methods: We completed a cross-sectional, secondary analysis of data from the All of Us Research Program, including 370,722 adults with electronic health record data available between January 2021-September 2023. We identified prevalence of disability, chronic pain, OUD, receipt of medications for OUD (MOUD), and OUD remission using diagnostic codes. We performed interaction analyses between chronic pain, disability subtype, and MOUD receipt in affecting OUD outcomes. Results: OUD was more common among individuals with physical (aOR: 2.74, 95% CI: 2.54-2.95), cognitive (2.19, 1.94-2.45), and multiple disabilities (2.43, 2.19-2.68), compared to those without disabilities. Among patients with OUD, those with physical disabilities were less likely to receive MOUD (0.81, 0.69-0.94). Compared to those without disabilities, chronic pain was associated with higher probabilities of OUD diagnosis and lower probabilities of MOUD and OUD remission across all subjects. These relationships were stronger for OUD diagnosis in cognitive disabilities, MOUD in multiple disabilities, and OUD remission in physical disabilities. Conclusions: Disability and chronic pain jointly shape disparities in OUD treatment and underscore the urgent need for care models that integrate OUD treatment with pain management and address the unique access challenges faced by people with disabilities.

Background: Loneliness and social isolation may contribute to tobacco and nicotine use, but existing studies have been inconsistent. This systematic review and meta-analysis examined these associations among adults amid the evolving nicotine product landscape. Methods: A systematic search of PubMed, MEDLINE, PsycINFO, and CINAHL identified peer-reviewed quantitative studies published between 2014 and 2025 searched in February-April 2026. Eligible studies included adults aged [≥]18 years examining loneliness and/or social isolation in relation to smoking or nicotine use. Two reviewers independently screened studies, extracted data, and assessed risk of bias (using the National Heart, Lung, and Blood Institute risk of bias tool). Random effects meta-analyses were conducted to estimate pooled odds ratio (OR) with 95% confidence intervals (CIs). Results: 22 studies involving 273,954 participants met inclusion criteria, and 14 studies were included in the meta-analysis. A majority of the studies had low risk of bias. Meta-analysis findings showed that social isolation or loneliness was associated with significantly higher odds of nicotine product use (OR 1.84, 95% CI 1.48-2.29). Although no statistically significant association of nicotine product use and social isolation or loneliness (OR 1.35, 95% CI 0.72-2.53), some studies suggested bidirectional relationships, with smoking contributing to reduced social support and greater isolation over time. Sensitivity analysis showed the robustness of the meta-analysis findings. Subgroup analysis found no statistically significant differences were seen between subgroups defined by type of nicotine product, age groups, social isolation vs loneliness, measures of nicotine use behaviours and pre- vs post- COVID-19 pandemic period in the meta-regression. Limitations of included studies and analysis are discussed. Conclusions: Loneliness and social isolation are significant psychosocial correlates of nicotine product use. Cessation interventions may benefit from integrating social support and mental health strategies alongside traditional nicotine dependence treatment.

Objectives: Tobacco and cannabis co-use is common, and reductions in one substance may theoretically lead to compensatory increases in the other. This secondary analysis examined whether cannabis cue-induced dorsolateral prefrontal cortex repetitive transcranial magnetic stimulation (DLPFC-rTMS) affects tobacco consumption among tobacco-using individuals with cannabis use disorder (CUD). Methods: Data were analyzed from a randomized, sham-controlled trial of DLPFC-rTMS for CUD. Participants were treatment-seeking adults with moderate or severe CUD who reported baseline tobacco use. Active or sham 10-Hz DLPFC-rTMS was delivered during cannabis cue exposure over 10 treatment visits. Linear mixed-effects models examined group differences in weekly percentage change from baseline in tobacco consumption over treatment and follow-up, adjusting for baseline tobacco consumption. Additional models examined whether changes in cannabis use were associated with changes in tobacco use. Results: Twenty participants were included, with 10 assigned to active rTMS and 10 to sham. Active rTMS was associated with a greater reduction in tobacco consumption than sham at 1-week post-treatment (t = -2.49, p = 0.015). Changes in cannabis use were not significantly associated with group differences in tobacco reduction. Estimated group differences did not indicate compensatory increases in tobacco use among participants with larger reductions in cannabis use. Conclusions: Cannabis cue-induced DLPFC-rTMS was associated with a short-term reduction in tobacco consumption relative to sham among tobacco-using individuals with CUD. These preliminary findings suggest possible cross-substance effects of DLPFC-rTMS and did not indicate compensatory tobacco increases. Larger trials specifically designed for cannabis-tobacco co-use are warranted.

Background and Aims: Anxiety remains prevalent among adolescents while tobacco and nicotine product use, especially the recent increases of novel product use such as e-cigarettes and nicotine pouches, raises further public health concerns. The associations between novel tobacco and nicotine product use and anxiety remains understudied. This study aims to determine whether tobacco and nicotine product use is associated with generalised anxiety and whether this association differs by used product. Design: Cross-sectional survey, School Health Promotion study in 2025. Setting: A school-based nationwide survey conducted in all Finnish lower and upper secondary schools. Participants: Students aged 13-20 years in three school levels: 8.-9. grade students in lower secondary schools (N= 94 743, 73% of the students), 1st and 2nd-year students in general upper secondary schools (n=47 248, 70% of the students) and of vocational institutions (n=24 998, 38% of the students). Measurements: Exclusive (single product) and non-exclusive ([≥]1 products) daily or weekly use of tobacco and nicotine products, including nicotine pouches, e-cigarettes, cigarettes, and smokeless tobacco (snus). Generalised anxiety was measured using the Generalised Anxiety Disorder Scale (GAD-7). The cut-off of >10 points indicated participants with moderate to severe self-reported generalised anxiety symptoms. Background variables included sociodemographic variables and heavy drinking. Results: Of the 166,989 participants 51.4% were females, mean age was 15.7 (SD 1.27), 21.2% reported generalised anxiety. Prevalence of generalised anxiety increased gradient-wise in accordance with both non-exclusive and exclusive use frequency of different tobacco and nicotine products, as well as with number of products used. Daily use of nicotine pouches was associated with higher odds of anxiety compared with never use (boys: adjusted odds ratios (aOR) 1.19, 95% CI, 1.05 to 1.34; girls: aOR 1.74, 95% CI, 1.58 to 1.91), yet the association between daily e-cigarette use seemed to be stronger (boys aOR 1.96, 95% CI, 1.54 to 2.49; girls: aOR 2.29, 95% CI, 2.09 to 2.51). Summary: Any use of tobacco and nicotine products, including new products, is associated with generalised anxiety among adolescents, with some differences between products. Measures to prevent the initiation of tobacco and nicotine product use and to promote mental health among adolescents should be enacted.

Introduction: Self-rated health is an important patient-centred measure of health. The relationship between cannabis use and self-rated health has been previously studied, although with methodologic concerns which we aimed to address in this investigation. Methods: Propensity score weighted analyses of the National Health and Nutrition Examination Survey (NHANES) 2009-2018 were conducted. The primary exposure was self-reported cannabis use in the 30 days prior to survey response. The primary outcome was self-rated health measured on a five-level ordinal scale. Secondary outcomes included the number of days in the past months with: i) poor physical health, ii) poor mental health, and iii) activity limitations related to poor health. A weighted proportional odds regression model was used for the primary analysis and weighted zero-inflated negative binomial regression models were used for each secondary analysis. Results: Among 22,055 adults aged 20-59 responding to the NHANES cannabis questionnaire, 14.4% endorsed use in the past 30 days. After reweighting the sample to balance cannabis users and non-users across sociodemographic, medical, and lifestyle characteristics, there was no statistically significant association between recent cannabis use and higher levels of self-rated health (OR 0.90, 95% CI 0.80-1.01). Cannabis use was associated with poor mental health and activity limitations in the past month, but not poor physical health. Conclusions: Recent cannabis use was not associated with self-rated health but was associated with poor mental health and activity limitations in the past month. Cannabis users at risk of poor mental health should be connected with clinicians to help guide therapy.

Adults aged [≥]65 years are increasingly using cannabis products. However, controlled pharmacokinetic and pharmacodynamic data on {Delta}9-tetrahydrocannabinol (THC) in this population are sparse, and remain limited to oral/oromucosal formulations. To characterize the acute pharmacokinetic and pharmacodynamic effects of oral and vaporized THC in healthy adults aged [≥]65, we conducted a two-arm, randomized, double-blind, placebo-controlled trial in which 20 participants (mean age 70.0, SD: 5.1 years) received oral (placebo, 5 mg, or 10 mg) or vaporized THC (placebo, 2 mg, or 4 mg) across three eight-hour sessions separated by [≥]72 hours. Outcomes included plasma pharmacokinetics, subjective drug effects, reinforcement value, cognitive performance, heart rate (HR), blood pressure (BP), and adverse events (AEs). Oral THC was associated with delayed, lower THC exposure (Tmax 60-90 min; Cmax 2.6-6.2 ng/mL), with 11-OH-THC concentrations approximately matching parent-THC; slow-rising subjective effects; no change in reinforcement value; no significant change in HR or BP; and no AEs. Vaporized THC was associated with rapid, THC-dominant exposure (Tmax 3 min; Cmax 24.6-53.8 ng/mL) and minimal 11-OH-THC concentrations; rapid-onset subjective effects; increased reinforcement value at 4 mg; and significant HR elevation peaking within 5 min, without significant BP change. Cognitive performance did not differ from placebo at any oral or vaporized THC dose. At vaporized THC 4 mg, two participants experienced five AEs. Oral and vaporized THC produce route-specific pharmacokinetic and pharmacodynamic profiles in adults aged [≥]65, including an increase in reinforcement value only after vaporization, and should therefore not be treated as interchangeable in risk assessment for older adults.

Multi-Cancer Detection (MCD) tests can detect more than 50 different types of cancer using a blood test. Recently passed law in the U.S. guarantees that Medicare will pay for these tests when they are FDA approved and show evidence for clinical benefit. This manuscript provides estimates of the cost of MCD tests to Medicare under different assumptions of cost per test, eligibility, and screening uptake in the eligible population. This manuscript additionally estimates the cost of follow-up testing resulting from false positive results, which are considered avoidable costs caused by the screening test.

BackgroundObservational comparisons of former smokers who use non-combusted nicotine products with former smokers who quit without them require that two quantities be measured precisely: which product is being used, and how long ago cigarette smoking stopped. Neither quantity is recorded by the National Health Insurance Service (NHIS) screening instrument used in a recent Korean cohort study of post-cessation e-cigarette use and lung cancer risk. We characterized both quantities in a contemporaneous, nationally representative survey of the same population. MethodsWe analyzed the public-release microdata of the Korea National Health and Nutrition Examination Survey (KNHANES), 2018 to 2023, restricted to adults aged 19 years and older. Former smokers were identified by smoking status, and cessation duration was taken from the item recording months since the last cigarette. Former smokers currently using a heated tobacco product (HTP) or an e-cigarette (EC) were compared with former smokers using neither. KNHANES 2018 asked a generic e-cigarette question and, separately, a checklist naming HTP brands, allowing the two product classes to be separated. Distributions were compared with rank-based methods, the age-duration relationship with Theil-Sen regression, and residual imbalance by restricting the comparison group to respondents age-matched to within two years. ResultsThe 2018 analytic sample comprised 1,348 former smokers, of whom 43 currently used HTP or EC and 1,305 used neither. Among the product-using former smokers, 58% reported HTP use without e-cigarette use, 21% reported both, and 21% reported e-cigarette use without HTP use; 79% reported any HTP use. Median cessation duration was 0.7 years (IQR 0.25 to 1.5) among product users and 12.0 years (IQR 5.0 to 20.0) among those using neither (Kolmogorov- Smirnov D = 0.76, P < 0.001), with the product user having quit more recently in 92% of cross-group pairs. The separation persisted within the short-term (<5 year) stratum (D = 0.34, P < 0.001; 73% of pairs) and after age matching, where the residual gap was 9.3 years. Cessation duration rose with age among those using no product (Theil-Sen slope +0.30 years per year) but was flat among product users (-0.01). Restricting to the screening-eligible stratum used in the cohorts high-risk analysis did not attenuate the imbalance: among those aged 50 to 80, median cessation among no-product quitters rose to 15.5 years (n = 858), and adding a 20 pack-year criterion left 421 no-product quitters with a median of 11.0 years against three HTP/EC users who had quit 0.25, 1.0 and 2.0 years earlier, despite closely matched cumulative exposure (mean 37.6 vs 37.7 pack-years). The overall contrast reproduced in every wave from 2018 to 2023, with an age-matched residual of 9 to 11 years. ConclusionsIn a nationally representative survey of the same population and the same calendar year as the NHIS screening cohort analyzed by Kim et al., Korean former smokers using non-combusted nicotine products differed from other former smokers in two respects that bear directly on how such comparisons should be read. First, they were predominantly HTP users: 79% reported any HTP use, and only 21% reported e-cigarette use without HTP use. Second, they had stopped smoking approximately a decade more recently, a difference that survived stratification at five years and exact age matching. Neither quantity is recorded in the NHIS screening instrument. Cohort estimates comparing post-cessation product users with other quitters should therefore be interpreted with caution if they do not precisely characterize product composition and to time since cessation, and future studies should measure both directly.

Background: As cannabis policy changes in the United States, secondhand cannabis smoke (SCS) is increasingly common, including within families. However, prevalence of exposure and clinical correlates over time in adolescents are not fully understood. Objectives: (1) To estimate the prevalence of SCS and personal cannabis use in US-based teens exposed to SCS, and (2) examine the cognitive trajectories of adolescents exposed to SCS compared to non-exposed peers. Methods: Data from the Adolescent Brain Cognitive Development (ABCD) Study was used. Participants (n=11,316 of full cohort with follow-up data; n=776 with self-reported family SCS exposure) attended yearly visits from ages 11-17, completing substance use interviews, toxicological testing, and the NIH Toolbox Cognitive battery. Youth with SCS but no personal cannabis use (n=419; 47% female) were matched on prenatal substance exposure, family substance use history, and sociodemographics to non-SCS exposed and non-cannabis-using youth with a 1:2 ratio (Controls n=838). Linear mixed-effects models assessed cognitive performance by SCS*age interactions, accounting for random effects of subject and family. Covariates included sex and alcohol, nicotine, and other substance use. Secondary models analyzed performance by cumulative waves of reported SCS exposure interacting with age. Results: Of the full cohort, 6.9% (n=776) reported exposure to SCS. Of these individuals, 46% endorsed lifetime personal cannabis use by age 17, relative to 20% of non-SCS exposed youth (OR=3.83[95%CI:3.29,4.44]). Within matched participants, SCS*age demonstrated a significant interaction on attention and inhibitory control ({beta}=-0.32, p=.028), with SCS demonstrating reduced improvement over time. More waves of exposure were also associated with worse performance over time ({beta}=-0.39, p=.057). Discussion: Almost half of those who had been exposed to SCS endorsed personal cannabis use. Cognitive findings were domain specific, similar to findings in secondhand tobacco: SCS exposed youth showed restricted improvement in attention and inhibitory control by age 17. Public health and policymakers should make efforts to curb youth SCS exposure, given the potential for risk which has not been fully explored to date.

Importance: Adolescent cannabis use is a growing concern due to its associations with long-term adverse mental health outcomes. However, the distinct, temporal associations of neurodevelopmental factors and childhood adverse life experiences (ALEs) with adolescent substance use in have not yet been fully elucidated. The Adolescent Brain Cognitive Development (ABCD) Study offers an unprecedented opportunity to prospectively examine neurobiological and socioenvironmental predictors of cannabis onset. Objective: To investigate magnetic resonance imaging-derived neurodevelopmental cortical brain Age Gap Estimate (brainAGE) and adverse life events as risk factors of early cannabis initiation. Design, Setting, and Participants: The ABCD Study is a longitudinal study across 22 sites in the United States. Data are collected starting at approximately 10 years old (currently at year-7 follow-up). Our analyses comprised 6688 (48% female) youth after exclusions. Main Outcomes and Measures: Cox proportional hazard models were computed to investigate brainAGE-sex interactions and 10 adversity dimensions at baseline as predictors of time to cannabis initiation up to age 18. Results: Mean age of initiation was 14.8 years (SD=1.43). Global brainAGE was modestly associated with cannabis initiation in females only (Hazard Ratio [HR]=1.05; 95% Confidence Interval [CI]=1.00-1.10, p = .049). Low socioeconomic status, caregiver substance use, family anger and arguments, and caregiver lack of supervision were associated with initiation (HRs = 1.11, 1.56, 1.09, 0.85, respectively; CIs = 1.04-1.19, 1.44-1.69, 1.09-1.19, 0.76-0.91, respectively; p's < .05). Other ALE dimensions and network-specific brainAGEs were not significantly associated with initiation. Conclusions and Relevance: Findings suggest that while cortical brainAGE may be somewhat increase vulnerability to adolescent cannabis use in females, its contributions are modest at best. In contrast, early childhood adversities such as socioeconomic factors and familial characteristics may present more substantive targets for prevention and intervention.

Background Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are widely prescribed for type 2 diabetes and obesity, yet their neuropsychiatric safety profile remains incompletely characterized. We aimed to systematically evaluate neuro-adverse event (AE) signals for six GLP-1RAs and to validate key findings using population-based data. Methods We conducted disproportionality analysis of FAERS data for semaglutide, liraglutide, dulaglutide, tirzepatide, exenatide, and lixisenatide. RORs were calculated for 93 predefined neuro-AE MedDRA PTs across 11 neurological categories. External validation used NHANES 2013-2018 (n=17,057; 70 GLP-1RA users) with survey-weighted regression. Results We identified 41 significant neuro-AE signals. Semaglutide showed the strongest neuromuscular signal, muscle atrophy (ROR 3.94; 95%CI 3.42-4.54), corroborated by tirzepatide (ROR 2.35; 95%CI 2.04-2.71). Exenatide generated the highest psychiatric signal: nervousness (ROR 4.03; 95%CI 3.70-4.40). NHANES confirmed higher depression odds (OR 2.05; 95%CI 1.32-3.19; P=0.001) and reduced sleep hours (beta -0.35; P=0.033). Conclusions GLP-1RAs carry multiple neuropsychiatric safety signals, including muscle atrophy as a potential class effect and depression risk corroborated by population-level data. These findings support heightened clinical monitoring.

Introduction: Nicotine Pouches are increasingly used as a smokeless alternative to cigarettes and other nicotine products, yet their acute cardiovascular effects remain poorly documented. While nicotine's impact on heart rate and electrocardiogram (ECG) parameters is well-documented in smoking, no trials have evaluated these effects specifically for nicotine pouches. Methods: This study is a single-center, double-blind, placebo-controlled, crossover trial which will include 20 healthy adult nicotine users. Participants will undergo three sessions, receiving either a placebo, 6 mg, or 14 mg nicotine pouch in random order. Heart rate obtained by an ECG and various other ECG parameters, vital signs, and subjective symptoms will be measured at baseline, and multiple time points over 30 minutes. Conclusions: This study aims to determine whether nicotine pouches cause acute changes in heart rate, ECG parameters, vital signs, and self-reported symptoms. We hypothesize that higher nicotine pouch does will lead to measurable increases in heart rate and other autonomic effects compared to placebo.

Objectives: To describe age-group differences in inability to afford dental treatment and cost related dental delay, among the US community-dwelling population. Study design: Descriptive analysis of nationally representative survey data. Methods: Using nationally representative Medical Expenditure Panel Survey data (2018-2021), we examined trends in inability to afford dental treatment and cost-related dental treatment delays across four age groups (2-17, 18-39, 40-64, [&ge;]65 years). Weighted analyses accounted for the complex survey design; statistical significance was set at p<0.001. Results: Cost-related delays declined modestly from 2018 to 2021 but remained most prevalent among adults aged 40-64 (4.8% for ages 40-64, 3.4% for ages 18- 64, 2.2% for ages>65 in 2021; p<0.001). Conclusion: Middle-aged adults seem to experience delays due to cost, underscoring the need for dental coverage to expand dental coverage for this group and to reduce their out-of-pocket costs.

Indiana still faces significant health challenges, ranking among the least healthy U.S. states due to high obesity rates, mental health issues, and other chronic conditions. These disparities are closely linked to inequities in healthcare access, which are largely shaped by social determinants of health. Using data from the Social Vulnerability Index and County Health Rankings and Roadmaps, this study analyzes trends in obesity, mental health, and premature death across Indiana counties before, during, and after the COVID-19 pandemic. Descriptive statistics, correlation analyses, and Negative Binomial regression models were used to evaluate county-level disparities. In 2018, higher rates of uninsured, obese, and physically inactive populations were associated with increased premature death. In 2020, diabetes, smoking, and alcohol consumption were significant factors. By 2022, unemployment, education, obesity, insurance, exercise access, and mental health provider availability were associated with premature death. Findings indicate that socially vulnerable counties experienced amplified health impacts, with obesity rising most sharply where exercise infrastructure was limited and poor mental health days increasing across all counties. These results highlight persistent service gaps and the critical need for targeted investments in recreational infrastructure and mental healthcare. Future research should examine policy influences and causal relationships to inform equity-focused interventions.

Background: Substance use disorders (SUDs) remain common worldwide and inadequately treated. Neuromodulation targets neural circuits involved in reward, craving, and cognitive control. However, the primary research literature has not been systematically mapped regarding the relative contributions of clinical and preclinical studies. Methods: We conducted a multi-database bibliometric analysis of primary studies on neuromodulation for SUD. Web of Science, Scopus, and PubMed were searched covering 2000-2025. After scope classification and exclusion of secondary literature, 810 primary research documents remained. Performance analysis and science mapping were performed with bibliometrix and VOSviewer. Results: Scientific output grew at a compound annual growth rate of 14.16% (2001-2025), accelerating after 2015. Of 810 studies, 82.8% were clinical, 12.5% preclinical, and 4.7% mixed/translational. Alcohol (31.5%) and nicotine/tobacco (25.7%) dominated the literature and were overwhelmingly clinical (>92%), whereas cocaine and opioids retained larger preclinical shares (24-27%). Repetitive transcranial magnetic stimulation (rTMS) was the leading modality (31.6%), followed by deep brain stimulation (24.9%) and transcranial direct current stimulation (24.2%). Keyword co-occurrence revealed three clusters: a clinical neuromodulation core, a nicotine/tobacco axis, and a preclinical reward-circuitry module. The United States and China led in output. Conclusions: Neuromodulation research for SUD is expanding rapidly and is heavily skewed toward clinical investigations. A persistent clinical-preclinical asymmetry and limited explicitly translational work constitute structural features of the field. Greater integration between mechanistic and clinical research is needed to advance definitive trials.

Introduction: Risk of recurrent opioid use during buprenorphine-naloxone (bup-nx) treatment is dynamic and remains elevated after initiation, with vulnerability shaped in part by treatment intensity and gaps between visits, yet routine outpatient care relies on episodic encounters and retrospective data. This mismatch can delay recognition of emerging instability and limit timely treatment adjustments. This paper reports the development and specification of an intervention strategy to address this mismatch. Methods: We used a structured, multi-phase design process to specify and configure a measurement-based care (MBC) strategy for bup-nx treatment (Bup-MBC) in outpatient addiction clinics through three phases: (1) a systematic review of patient-reported outcome measures (PROMs) for substance use treatment; (2) a qualitative needs assessment using the Theoretical Domains Framework and COM-B (Capability, Opportunity, Motivation-Behavior) model to identify gaps in risk monitoring, agency, and trust; and (3) iterative co-design with multidisciplinary clinicians to refine workflow fit and trust-preserving use of data. Patients informed item and feedback content during the needs assessment but did not participate in the co-design cycles. Results: Bup-MBC integrates (1) brief between-visit PROMs (e.g., withdrawal, craving, adherence); (2) immediate non-punitive patient feedback; (3) clinician-facing summaries and non-directive prompts in the electronic health record (EHR); and (4) an opt-in between-visit outreach pathway with predefined safety triggers, all configured within existing EHR and patient portal infrastructure. It targets patient and clinician capability to recognize changes in risk, opportunity for action through structured monitoring and visit preparation, and trust and agency through non-punitive communication, without adding substantial burden. The full measure set, severity bands, and question-to-action map are provided as supplementary material. Key trade-offs included prioritizing single-item measures for feasibility, balancing opt-in outreach with safety overrides, and assuming routine clinician use of summaries. Conclusion: This development study specifies an EHR-integrated MBC strategy for outpatient bup-nx treatment. As single-center design work with co-design limited to clinicians and delivery contingent on portal or text-message access, its outputs are hypotheses about mechanism and fit rather than demonstrated effects. Feasibility studies are needed to evaluate uptake, acceptability, workflow fit, and effects on treatment.

Objectives Outpatient buprenorphine-naltrexone (bup-nx) treatment reduces overdose risk, yet many patients still return to use or disengage from treatment. We sought to understand how patients and prescribers experience and manage relapse risk, monitoring, and treatment agency in routine bup-nx treatment to identify gaps in current practice. Methods We conducted a qualitative needs assessment using semi structured, critical incident interviews with patients receiving outpatient bup-nx and prescribers who manage bup-nx treatment. Interviews examined situations involving relapse risk and empowerment in treatment decisions. We structured data collection and analysis using the Theoretical Domains Framework and COM B model to characterize determinants. Transcripts were coded deductively and inductively until code level saturation was reached. Results Participants (9 patients, 8 prescribers) described nine treatment needs mapped to the Capability, Opportunity, and Motivation components of the COM B model. These themes highlighted how patient agency in bup-nx treatment was constrained by physiologic and emotional states, with withdrawal, craving, pain, and distress often overriding longer term goals. Relapse vulnerability was experienced as dynamic and intensifying between visits, while clinical detection remained anchored to visit bound assessments, urine drug testing, refill patterns, and crisis driven contact, creating blind spots. Structural friction (pharmacy rules, insurance disruptions, transportation and housing instability), stigma from family and recovery communities, and motivational processes tied to fluctuating readiness and trust in monitoring further shaped engagement, disclosure, and dosing decisions; the same monitoring tools could either support honest disclosure or provoke concealment when perceived as punitive. Conclusions Relapse risk and agency in bup-nx treatment are negotiated as dynamic processes within structurally constrained and trust sensitive systems. Addressing the identified capability, opportunity, and motivation gaps will require patient centered, trust preserving approaches to monitoring and shared decision making.
