Is it "loud" enough?: A qualitative investigation of blunt use among African American young adults.

Heavy blunt use is common among young adult cannabis users, especially African Americans. This exploratory qualitative study aimed to examine how African American young adults understand, talk about and experience their blunt use. Semi-structured interviews were conducted with adults reporting daily or almost daily blunt use in the past month (N = 20; 75% male). Thematic analysis of the audio-recorded interviews revealed aspects of how blunts are described, made and used among heavy blunt users. The three emergent themes have implications for the assessment of cannabis use and intervention development for heavy blunt users.

Reductions in tobacco use in naltrexone, relative to buprenorphine-maintained individuals with opioid use disorder: Secondary analysis from the National Drug Abuse Treatment Clinical Trials Network.

BACKGROUND: Smoking prevalence in individuals with opioid use disorder (OUD) is over 80%. Research suggests that opioid use significantly increases smoking, which could account for the strikingly low smoking-cessation rates observed in both methadone- and buprenorphine-maintained patients, even with the use of first-line smoking-cessation interventions. If opioids present a barrier to smoking-cessation, then better smoking outcomes should be observed in OUD patients treated with extended-release naltrexone (XR-NTX, an opioid antagonist) compared to those receiving buprenorphine (BUP-NX, a partial opioid agonist). METHODS: The current study is a secondary analysis of a 24-week, multi-site, open-label, randomized clinical trial conducted within the National Drug Abuse Treatment Clinical Trials Network comparing the effectiveness of XR-NTX vs. BUP-NX for adults with OUD. Longitudinal mixed effects models were used to determine if there was a significant reduction in cigarette use among daily smokers successfully inducted to treatment (n = 373) and a subset of those who completed treatment (n = 169). RESULTS: Among daily smokers inducted onto OUD medication, those in the XR-NTX group smoked fewer cigarettes per day (M = 11.36, SE = 0.62) relative to smokers in the BUP-NX group (M = 13.33, SE = 0.58) across all study visits, (b (SE) = -1.97 (0.55), p < .01). Results were similar for the treatment completers. CONCLUSIONS: OUD patients treated with XR-NTX reduced cigarette use more than those treated with BUP-NX, suggesting that XR-NTX in combination with other smoking cessation interventions might be a better choice for OUD smokers interested in reducing their tobacco use.

Design considerations for a remote randomized multi-site clinical trial evaluating an e-health self-management program for chronic pain patients receiving opioid therapy.

Based on the adverse consequences and inadequate evidence of effectiveness for long-term opioid therapy (LOT), the CDC developed recommendations to decrease the use of LOT and morphine equivalent dose (MED) for patients receiving LOT. However, the majority of these patients report that opioid medication is significantly beneficial for pain management and are hesitant to reduce/decrease its use. Compounding the problem is poor access to non-pharmacologic therapies for many patients due to insurance reimbursement structures and limited pain-service availability. EMPOWER is an intent-to-treat, two-arm, open-label, randomized controlled trial evaluating a web-based self-management chronic pain program (E-Health) that has been found to reduce self-reported MED, while also decreasing pain, in two randomized controlled trials. Approximately 400 chronic pain patients receiving LOT at a daily average prescribed MED ≥ 20 mg at one of two U.S. healthcare systems, located in North Carolina and Ohio, will be randomized in a 1:1 ratio to treatment as usual (TAU) or TAU plus E-Health (E-Health+). TAU consists of LOT from a prescribing clinician. E-Health+ participants are provided with a 4-month E-Health subscription (active treatment phase). All participants will complete web-based self-report measures at baseline, the end of the active treatment phase, and 6-months post-active treatment. Opioid prescription information will be collected from the participants' electronic health record (EHR) from baseline through 6 months post-active treatment. This paper describes design considerations for this unique trial which is conducted completely remotely, with no in-person visits, and utilizes the EHR for participant identification and primary outcome collection.

The Opioid-overdose Reduction Continuum of Care Approach (ORCCA): Evidence-based practices in the HEALing Communities Study.

BACKGROUND: The number of opioid-involved overdose deaths in the United States remains a national crisis. The HEALing Communities Study (HCS) will test whether Communities That HEAL (CTH), a community-engaged intervention, can decrease opioid-involved deaths in intervention communities (n = 33), relative to wait-list communities (n = 34), from four states. The CTH intervention seeks to facilitate widespread implementation of three evidence-based practices (EBPs) with the potential to reduce opioid-involved overdose fatalities: overdose education and naloxone distribution (OEND), effective delivery of medication for opioid use disorder (MOUD), and safer opioid analgesic prescribing. A key challenge was delineating an EBP implementation approach useful for all HCS communities. METHODS: A workgroup composed of EBP experts from HCS research sites used literature reviews and expert consensus to: 1) compile strategies and associated resources for implementing EBPs primarily targeting individuals 18 and older; and 2) determine allowable community flexibility in EBP implementation. The workgroup developed the Opioid-overdose Reduction Continuum of Care Approach (ORCCA) to organize EBP strategies and resources to facilitate EBP implementation. CONCLUSIONS: The ORCCA includes required and recommended EBP strategies, priority populations, and community settings. Each EBP has a "menu" of strategies from which communities can select and implement with a minimum of five strategies required: one for OEND, three for MOUD, and one for prescription opioid safety. Identification and engagement of high-risk populations in OEND and MOUD is an ORCCArequirement. To ensure CTH has community-wide impact, implementation of at least one EBP strategy is required in healthcare, behavioral health, and criminal justice settings, with communities identifying particular organizations to engage in HCS-facilitated EBP implementation.

A brief telephone-delivered peer intervention to encourage enrollment in medication for opioid use disorder in individuals surviving an opioid overdose: Results from a randomized pilot trial.

BACKGROUND: Medication for opioid use disorder (MOUD) can decrease the risk of opioid overdose (OOD) in individuals with opioid use disorder. Peer recovery support services (PRSS) are increasingly used to promote MOUD engagement but evidence of their efficacy is limited. This study's objective was to evaluate a single 20-minute telephone-delivered PRSS intervention for increasing MOUD enrollment and decreasing recurring OODs. METHOD: This single-site, randomized controlled pilot trial enrolled adults, primarily recruited from a syringe service program, with an opioid-positive urine drug screen (UDS) reporting having been treated for an OOD within the past 6 months. Participants (N = 80) were randomized to PRSS (n = 40) or Control (n = 40) condition with all participants receiving personally-tailored OOD education and naloxone. Outcome measures obtained at 3 (n = 66), 6 (n = 58), and 12 (n = 44) months post-randomization included verified MOUD enrollment (primary), self-reported OOD, and opioid use assessed by self-report and UDS. RESULTS: Through 12-month follow-up, 32.5 % of PRSS, compared to 17.5 % of Control participants enrolled in MOUD (X2 = 2.4, p = 0.12; odds ratio = 2.27 (0.79-6.49)). PRSS participants were significantly less likely to have experienced an OOD through 12-month follow-up (12.5 % of PRSS participants, 32.5 % of Control, p = 0.03). No significant treatment effect was found for opioid use through 12-month follow-up as measured by either opioid-positive UDSs or self-reported past month opioid use days. Based on self-report, PRSS had good acceptability for both the interventionists and participants. CONCLUSIONS: The results suggest that further development and testing of this PRSS telephone intervention to encourage MOUD enrollment and reduce OOD may be warranted.

Evaluation of a personally-tailored opioid overdose prevention education and naloxone distribution intervention to promote harm reduction and treatment readiness in individuals actively using illicit opioids.

BACKGROUND: Opioid overdose prevention education and naloxone distribution (OEND) programs include information on general risk factors, overdose recognition, and naloxone utilization. This study evaluated a personally-tailored OEND (PTOEND) intervention designed to promote harm reduction and treatment readiness for illicit opioid users by also including education about personal overdose-risk factors and medication for opioid use disorder (MOUD). METHOD: A secondary analysis of a randomized controlled trial testing a Peer recovery support service (PRSS) intervention, relative to Control, in adult illicit opioid users reporting treatment for an overdose in the prior 6 months. PTOEND, a 30-minute computer-guided intervention, was administered by a research assistant at the randomization visit to all participants (N = 80). Participants completed a telephone visit 3 weeks post-randomization (n = 74) to assess changes in opioid overdose/MOUD knowledge and treatment readiness. Participants completed in-person visits at 3 (n = 66), 6 (n = 58), and 12 (n = 44) months post-randomization to assess illicit opioid use and naloxone utilization (all time points) and overdose-risk behaviors (12 months). We conducted pre-post analyses of the impact of PTOEND controlling for the PRSS effect. RESULTS: PTOEND increased knowledge of overdose (79.8% to 81.5%, p < 0.05) and MOUD (66.9% to 75.0%, p < 0.01) and decreased perceived treatment barriers (2.1 to 1.9, p < 0.01); desire to quit all substances increased (7.2 to 7.8, p = 0.05). Self-reported opioid use was significantly decreased at each follow-up (all p < 0.01). Self-reported overdose-risk behaviors decreased significantly (6.2 to 2.4, p < 0.01). A majority of participants (65 %) reported naloxone utilization. CONCLUSIONS: PTOEND may be effective for promoting harm reduction and treatment readiness.

Increased Morbidity and Mortality in Hypertensive Patients With Substance Use Disorders: Electronic Health Record Findings.

OBJECTIVE: Substance use disorder (SUD) management by medical providers may be important for patients with comorbid health conditions exacerbated by SUD. This study evaluated potential associations of SUD with morbidity and mortality in a large sample of hypertensive patients. METHOD: Analysis of a limited data set was obtained through IBM Watson Health Explorys, a platform integrating data from electronic health records. Matched controls were defined for each of five SUDs: tobacco use disorder (TUD), alcohol use disorder (AUD), cocaine use disorder (COUD), opioid use disorder (OUD), and cannabis use disorder (CUD) using Mahalanobis distance within propensity score calipers. All patients were from The MetroHealth System (Cleveland, OH) and had diagnosed hypertension. SUD group participants had diagnosed abuse/dependence for the substance of interest. Controls for each SUD group had no diagnosis code related to the substance of interest and were selected to match the SUD patients on several factors. Total sample sizes for each SUD-control comparison ranged from 3,176 (CUD) to 49,696 (TUD); proportions of female patients ranged from 31.7% (AUD) to 51.2% (TUD). Outcomes were diagnosis (yes/no) of the following: cerebrovascular accident, myocardial infarction, renal failure, and all-cause mortality. RESULTS: Logistic regressions revealed that SUD was significantly associated with cerebrovascular accident (odds ratios [ORs]: TUD = 2.23; AUD = 1.68; COUD = 2.53; OUD = 1.87; CUD = 2.20), renal failure (ORs: TUD = 1.46; COUD = 2.09; OUD = 1.77), myocardial infarction (ORs: TUD = 2.96; AUD = 1.92; COUD = 3.00), and mortality (ORs: TUD = 1.34; AUD = 1.60; COUD = 1.83; OUD = 1.35; CUD = 1.39). CONCLUSIONS: Among patients with hypertension, those with SUDs appear to have significantly greater risk for morbidity and mortality, suggesting the importance of managing SUD in hypertensive patients.

The association between regular cocaine use, with and without tobacco co-use, and adverse cardiovascular and respiratory outcomes.

BACKGROUND: Understanding the potential impact of cocaine use on health is increasingly important as cocaine use rises in the U.S. OBJECTIVES: This study evaluated the associations of regular cocaine use, with and without tobacco co-use, with cardiovascular and respiratory outcomes. METHODS: Analysis of a limited dataset obtained through IBM Watson Health Explorys, a platform integrating electronic health record data. Matched controls were defined for: 1) cocaine-using patients (n = 8244; 44 % female); and subgroups of cocaine-using patients: 2) with an encounter diagnosis for tobacco use disorder (TUD; n = 4706); and 3) without a TUD diagnosis (non-TUD; n = 3538). Patients had at least one documented medical evaluation in the MetroHealth System (Cleveland, Ohio). Cocaine-using patients had an encounter diagnosis of cocaine abuse/dependence and/or ≥2 cocaine-positive drug screens. Control patients, with no documented cocaine-use, were matched to the cocaine-using patients on demographics, residential zip code median income, body mass index, and, for the total sample, TUD-status. Outcomes were encounter diagnosis (yes/no) of cerebrovascular accident, heart arrhythmia, myocardial infarction, subarachnoid hemorrhage, asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and all-cause mortality. RESULTS: TUD-patients had the greatest prevalence of cardiovascular and respiratory disease, regardless of cocaine-use indication. In the total sample, TUD, and non-TUD subgroups, regular cocaine use was significantly associated with greater risk for cerebrovascular accident, arrhythmia, myocardial infarction, asthma, COPD, pneumonia and mortality. CONCLUSIONS: Cocaine use is associated with significantly greater risk of adverse cardiovascular and respiratory diagnoses and all-cause mortality.

Medication treatment for opioid use disorder in expectant mothers (MOMs): Design considerations for a pragmatic randomized trial comparing extended-release and daily buprenorphine formulations.

Opioid use disorder (OUD) in pregnant women has increased significantly in recent years. Maintaining these women on sublingual (SL) buprenorphine (BUP) is an evidence-based practice but BUP-SL is associated with several disadvantages that an extended-release (XR) BUP formulation could eliminate. The National Drug Abuse Treatment Clinical Trials Network (CTN) is conducting an intent-to-treat, two-arm, open-label, pragmatic randomized controlled trial, Medication treatment for Opioid-dependent expectant Mothers (MOMs), to compare mother and infant outcomes of pregnant women with OUD treated with BUP-XR, relative to BUP-SL. A second aim is to determine the relative economic value of utilizing BUP-XR. Approximately 300 pregnant women with an estimated gestational age (EGA) of 6-30 weeks, recruited from 12 sites, will be randomized in a 1:1 ratio to BUP-XR or BUP-SL, balancing on site, EGA, and BUP-SL status (taking/not taking) at the time of randomization. Participants will be provided with study medication and attend weekly medication visits through 12 months postpartum. Participants will be invited to participate in two sub-studies to evaluate the: 1) mechanisms by which BUP-XR may improve mother and infant outcomes; and 2) effects of prenatal exposure to BUP-XR versus BUP-SL on infant neurodevelopment. This paper describes the key design decisions for the main trial made during protocol development. This Investigational New Drug (IND) trial uniquely uses pragmatic features where feasible in order to maximize external validity, hence increasing the potential to inform clinical practice guidelines and address multiple knowledge gaps for treatment of this patient population.

The association between regular cannabis use, with and without tobacco co-use, and adverse cardiovascular outcomes: cannabis may have a greater impact in non-tobacco smokers.

BACKGROUND: Understanding the potential impact of cannabis use on cardiovascular health is increasingly important as cannabis use rises in the U.S. Objectives: This study evaluated the associations between regular cannabis use, with and without tobacco co-use, and cardiovascular outcomes. METHODS: Analysis of a limited dataset obtained through IBM Watson Health Explorys, a platform integrating electronic health record data. Matched controls using Mahalanobis distance within propensity score calipers were defined for: 1) cannabis-using patients (n = 8,944; 43% female); and subgroups of cannabis-using patients: 2) with an encounter diagnosis for tobacco use disorder (TUD; n = 4,682); and 3) without a TUD diagnosis (non-TUD; n = 4,262). Patients had ≥1 blood pressure measurement and blood chemistry lab result in the MetroHealth System (Cleveland, Ohio). Cannabis-using patients had an encounter diagnosis of cannabis abuse/dependence and/or ≥2 cannabis-positive urine drug screens. Control patients, with no cannabis-use-documentation, were matched to the cannabis-using patients on demographics, residential zip code median income, body mass index, and, for the total sample, TUD-status. Outcomes were encounter diagnosis (yes/no) of cerebrovascular accident (CVA), heart arrhythmia, myocardial infarction, subarachnoid hemorrhage (SAH), and all-cause mortality. RESULTS: TUD-patients had the greatest prevalence of cardiovascular disease, regardless of cannabis-use indication. In the total sample and non-TUD subgroup, regular cannabis use was significantly associated with greater risk for CVA, arrhythmia, SAH, and mortality. In the TUD subgroup, regular cannabis use was significantly associated with greater risk for arrhythmia and SAH. CONCLUSIONS: Cannabis use is associated with significantly greater risk of adverse cardiovascular diagnoses and overall death, particularly in non-tobacco users.

Blunt use and menthol cigarette smoking: An examination of adult marijuana users.

INTRODUCTION: Use of menthol cigarettes remains highly prevalent among African American smokers and has increased among White and Hispanic/Latino smokers. Research is needed to examine if behavioral factors, such as marijuana use, are differentially associated with menthol cigarette use among racially/ethnically diverse samples of marijuana users. METHODS: Using data from the 2017 National Survey on Drug Use and Health, this study examined the association between past month marijuana (blunt versus non-blunt) and cigarette (non-menthol cigarette versus menthol cigarette versus no cigarette) use, as well as racial/ethnic differences in this relationship. RESULTS: Among all marijuana users (N = 5,137), 34.1% smoked blunts, 28.7% smoked non-menthol cigarettes and 18.0% smoked menthol cigarettes, with the highest rates of blunt (63.8%) and menthol cigarette (38.9%) use found among African American adults. Multinomial logistic regression analyses revealed a significant association between blunt use and non-menthol cigarette use (versus non-use) and menthol cigarette use (versus non-menthol cigarette and no cigarette use) among the full sample. When stratified by race/ethnicity, this finding was consistent for non-Hispanic White (n = 3,492) and partially consistent for Hispanic/Latino (n = 839) adults. However, among African American adults (n = 806), blunt use was not significantly associated with non-menthol cigarette use or menthol cigarette use. DISCUSSION: Blunt use is associated with increased odds of non-menthol and menthol cigarette use, but only among Hispanic/Latino and White adults. Examining racial/ethnic differences in the association between marijuana and tobacco use is important to understanding disparities and informing prevention and treatment interventions and drug policies.

Differential Posttreatment Outcomes of Methylphenidate for Smoking Cessation for Individuals With ADHD.

BACKGROUND AND OBJECTIVES: In a multisite, randomized study (CTN-0029), a 3-month course of Osmotic-Release Oral System Methylphenidate (OROS-MPH) improved smoking cessation in a group of patients with higher baseline severity in Attention-Deficit/Hyperactivity Disorder (ADHD). This treatment, however, worsened smoking cessation outcome in the group with lower baseline ADHD severity. We want to examine whether this differential treatment effect persisted after OROS-MPH was discontinued. METHODS: We conducted a secondary analysis of the 1-month follow-up data from CTN-0029 after the discontinuation of OROS-MPH (N = 134). Nicotine patch was tapered during this month. We tested whether OROS-MPH had an effect on self-reported 7-day abstinence by week, as well as possible treatment by baseline ADHD severity interactions. RESULTS: Abstinence diminished overall in time after the end of the treatment. In the high baseline severity group, patients who received OROS-MPH had an advantage in 7-day abstinence at week 15 (40% for OROS-MPH vs 20% for placebo, odds ratio = 2.63, P = .028). In the lower severity group (n = 121), no difference was detected (29% for OROS-MPH vs 32% for placebo, P = 1.00) between the two treatment groups. There was also a significant treatment by baseline ADHD severity interaction (P = .03). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: OROS-MPH promotes abstinence beyond the course of treatment for patients with more severe ADHD, while the paradoxical effects in the lower baseline severity group is not persistent after medication discontinuation. Targeting ADHD in smoking cessation as a comorbidity therefore can have broader impact with more precise patient selection. (Am J Addict).

Regular cannabis use, with and without tobacco co-use, is associated with respiratory disease.

BACKGROUND: Cannabis use is a potential risk factor for respiratory disease but its role apart from tobacco use is unclear. We evaluated the association between regular cannabis use, with and without tobacco co-use, and onset of asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. METHODS: Analysis of a limited data set obtained through IBM Watson Health Explorys, an electronic-health-record-integration platform. Matched controls using Mahalanobis distance within propensity score calipers were defined for: 1) cannabis-using patients (n = 8932); and subgroups of cannabis-using patients: 2) with an encounter diagnosis for tobacco use disorder (TUD; n = 4678); and 3) without a TUD diagnosis (non-TUD; n = 4254). Patients had at least: one recorded blood pressure measurement and one blood chemistry lab result in the MetroHealth System (Cleveland, Ohio). Cannabis-using patients had an encounter diagnosis of cannabis abuse/dependence and/or ≥2 cannabis-positive urine drug screens (UDSs). Control patients, not having cannabis-related diagnoses or cannabis-positive UDSs, were matched to the cannabis-using patients on demographics, residential zip code median income, body mass index, and, for the total sample, TUD-status. RESULTS: Regular cannabis use was significantly associated with greater risk for asthma (odds ratio (OR) = 1.44; adjusted odds ratio (aOR) = 1.50; OR = 1.32), COPD (OR = 1.56; aOR = 1.44; OR = 2.17), and pneumonia (OR = 1.80; OR = 1.84; OR = 2.13) in the total sample and TUD and non-TUD subgroups, respectively. TUD-patients had the greatest prevalence of respiratory disease, regardless of cannabis-use indication. CONCLUSIONS: Regular cannabis use is associated with significantly greater risk of respiratory disease regardless of TUD status. Future research to understand the impact of cannabis use on respiratory health is warranted.

Blunts versus joints: Cannabis use characteristics and consequences among treatment-seeking adults.

BACKGROUND: Despite the high prevalence of blunt smoking among cannabis users, very few studies examine the clinical profile of blunt smokers relative to those using more common methods of cannabis use, such as joints. METHODS: The current study uses baseline data from the ACCENT (Achieving Cannabis Cessation-Evaluating N-acetylcysteine Treatment) study, a multi-site randomized pharmacotherapy clinical trial within the National Drug Abuse Treatment Clinical Trials Network, to predict the association between blunt and joint use frequency and cannabis use characteristics (e.g., grams of cannabis used) and consequences (e.g., withdrawal) among past-month cannabis users (N = 377) who were screened for study participation. RESULTS: After controlling for race, age, gender, other forms of cannabis use (including joint use) and nicotine dependence, multivariable linear regression models indicated that the number of days of blunt use in the past month was a significant predictor of the average amount of cannabis per using day (t = 3.04, p < .01), the estimated average cost of cannabis (t = 2.28, p < .05) and Cannabis Withdrawal Scale scores (t = 1.94, p < .05). Frequency of joint use did not significantly predict any of the cannabis use characteristics or consequences. CONCLUSIONS: Blunt smokers may present to treatment with greater amounts of cannabis smoked and more intense withdrawal symptoms, which may adversely impact their likelihood of successful abstinence. Cannabis-dependent blunt smokers may be more likely to benefit from treatment that targets physiological and mood-related withdrawal symptoms.

Medical complications associated with substance use disorders in patients with type 2 diabetes and hypertension: electronic health record findings.

BACKGROUND AND AIMS: Screening for substance use disorder (SUD) in general medical settings may be particularly important in patients with comorbid health conditions exacerbated by SUD. This study evaluated whether SUD is associated with type 2 diabetes mellitus (T2DM) complications in patients with co-occurring T2DM and hypertension. DESIGN: Analysis of a limited data set obtained through IBM Watson Health Explorys, a platform integrating data from electronic health records. Matched controls were defined for each of five SUDs: tobacco use disorder (TUD), opioid use disorder (OUD), cocaine use disorder, cannabis use disorder (CUD) and alcohol use disorder (AUD) using Mahalanobis distance within propensity score calipers. SETTING: All patients were seen in the MetroHealth System (Cleveland, OH, USA) and had diagnosis codes for T2DM and hypertension. PARTICIPANTS: SUD group participants had a diagnosis of abuse/dependence for the substance of interest. Controls for each SUD group had no diagnosis code related to the SUD of interest and were selected to match the SUD patients on demographics, residential zip code median income and body mass index. Total sample sizes for each SUD-control comparison ranged from 1160 for CUD to 22 128 for TUD. MEASUREMENTS: Outcome was diagnosis (yes/no) of four T2DM complications (cerebrovascular accident, diabetic neuropathy, diabetic renal disease, myocardial infarction) and all-cause mortality. FINDINGS: Logistic regressions revealed that SUD was significantly associated with greater risk of cerebrovascular accident [TUD odds ratio (OR) = 1.79, OUD-OR = 1.94, cocaine use disorder OR = 2.67], diabetic neuropathy [TUD-adjusted OR (aOR) = 1.47, cocaine use disorder-aOR = 1.35, AUD-aOR = 1.27], diabetic renal disease (TUD-aOR = 1.25, OUD-OR = 1.34), myocardial infarction (TUD-OR = 1.96, OUD-OR = 2.01, cocaine use disorder-OR = 2.68, CUD-OR = 2.48, AUD-OR = 1.42) and mortality (TUD-OR = 1.15, cocaine use disorder-OR = 1.61, CUD-OR = 1.49, AUD-OR = 1.35). CONCLUSIONS: Among patients in Ohio USA with both type 2 diabetes mellitus (T2DM) and hypertension, those with substance use disorders appear to have greater risk for T2DM complications and all-cause mortality.

Substance use outcomes in cocaine-dependent tobacco smokers: A mediation analysis exploring the role of sleep disturbance, craving, anxiety, and depression.

BACKGROUND: Sleep disturbance may play a role in cocaine use outcomes and, hence, may be a potential therapeutic target for cocaine use disorder (CUD). Research in this area, which has largely relied on resource-intensive polysomnography, would be facilitated by identifying a self-report sleep measure predictive of CUD outcomes and by a better understanding of the mechanisms by which sleep may impact CUD outcomes. This study tested the predictive validity of the Pittsburgh Sleep Quality Index (PSQI), a self-report assessment of past-month sleep quality. To better understand potential mechanisms, mediation models relating sleep disturbance to CUD outcomes were evaluated. METHODS: This is a secondary analysis of data from cocaine-dependent (n = 290) participants in a multi-site trial evaluating smoking-cessation treatment for stimulant-dependent patients. The PSQI was collected at baseline; the outcomes of interest were cocaine and drug abstinence at end-of-treatment (weeks 9-10). Potential mediators, measured in weeks 1-8, were: cocaine craving (Brief Substance Craving Scale); and anxiety and depression symptoms (Hospital Anxiety and Depression Scale). Mediation techniques were used to evaluate mediation effects separately and jointly. RESULTS: The majority of participants (58.3%) had baseline sleep disturbance. Sleep disturbance was not a significant predictor of end-of-treatment abstinence when regressed without consideration of mediators. Cocaine craving, anxiety, and depression were significant mediators, both separately and jointly, of an effect of baseline sleep disturbance on end-of-treatment abstinence. CONCLUSION: This exploratory analysis suggests that there may be an indirect relationship between self-reported sleep quality and substance use outcomes in cocaine-dependent patients, mediated by craving, anxiety, and depression.

Exploring longitudinal course and treatment-baseline severity interactions in secondary outcomes of smoking cessation treatment in individuals with attention-deficit hyperactivity disorder.

BACKGROUND: A double blind, placebo-controlled randomized trial (NCT00253747) evaluating osmotic-release oral system methylphenidate (OROS-MPH) for smoking-cessation revealed a significant interaction effect in which participants with higher baseline ADHD severity had better abstinence outcomes with OROS-MPH while participants with lower baseline ADHD severity had worse outcomes. OBJECTIVES: This current report examines secondary outcomes that might bear on the mechanism for this differential treatment effect. METHODS: Longitudinal analyses were conducted to evaluate the effect of OROS-MPH on three secondary outcomes (ADHD symptom severity, nicotine craving, and withdrawal) in the total sample (N = 255, 56% Male), and in the high (N = 134) and low (N = 121) baseline ADHD severity groups. RESULTS: OROS-MPH significantly improved ADHD symptoms and nicotine withdrawal symptoms in the total sample, and exploratory analyses showed that in both higher and lower baseline severity groups, OROS-MPH statistically significantly improved these two outcomes. No effect on craving overall was detected, though exploratory analyses showed statistically significantly decreased craving in the high ADHD severity participants on OROS-MPH. No treatment by ADHD baseline severity interaction was detected for the outcomes. CONCLUSIONS: Methylphenidate improved secondary outcomes during smoking cessation independent of baseline ADHD severity, with no evident treatment-baseline severity interaction. Our results suggest divergent responses to smoking cessation treatment in the higher and lower severity groups cannot be explained by concordant divergence in craving, withdrawal and ADHD symptom severity, and alternative hypotheses may need to be identified.

Neurocognitive Profiling of Adult Treatment Seekers Enrolled in a Clinical Trial of a Web-delivered Intervention for Substance Use Disorders.

OBJECTIVE: This study is a secondary descriptive analysis that explores and compares the cognitive profiles of adults entering treatment at geographically diverse community-based substance use disorder treatment facilities. METHODS: Performance on cognitive measures at baseline was compared across 5 primary substance subgroups of individuals (alcohol = 104; cocaine = 102; stimulants = 69; opioids = 108; marijuana = 114) enrolled in a web-based psychosocial treatment study conducted within the National Drug Abuse Treatment Clinical Trials Network. MicroCog subtests were used to assess cognitive domains of attention and mental control, reasoning and cognitive flexibility, and spatial processing. RESULTS: The average age of onset for a substance use disorder was early to mid-20s, with marijuana users reporting the earliest age of onset (mean 19.9, SD 7.5) and stimulant users reporting the latest (mean 25.2, SD 9.9). Among the total sample, half (49.7%) demonstrated impairment in cognitive flexibility and reasoning, and over one-third (37.3%) had impairment in verbal learning and memory. Stimulant (37.68%) and cocaine (34.31%) users showed significantly greater clinical impairment in attention and mental control compared with alcohol users (17.31%) and opioid (21.30%) users (stimulant subgroup only) (χ [4] = 10.97, P = 0.027). Cocaine users showed the greatest overall impairment across total and proficiency subtest scores, although these were not statistically different from other subgroups. CONCLUSIONS: These findings confirmed previous studies, indicating a high prevalence of significant cognitive dysfunction across all substance use categories among treatment-seeking adults, and found that cocaine use appears to be associated with the most impairment. Increasing knowledge of similarities and differences between primary substance subgroups can help guide substance use disorder treatment planning.

Baseline Cigarette Smoking Status as a Predictor of Virologic Suppression and CD4 Cell Count During One-Year Follow-Up in Substance Users with Uncontrolled HIV Infection.

Cigarette smoking is prevalent in people living with HIV/AIDS (PLHIV) who abuse alcohol and/or illicit substances. This study evaluated whether smoking is predictive of virologic non-suppression (> 200 copies/mL) and low CD4 count (< 200 cells/mm3) during 1-year follow-up in medically hospitalized, substance-using PLHIV recruited for a multi-site trial. Smoking status was assessed with the Heaviness of Smoking Index (HSI). Analyses revealed that, controlling for baseline differences and adherence to antiretroviral therapy, non-smokers (n = 237), compared to smokers scoring in the medium-to-high range on the HSI (n = 386), were significantly more likely to achieve viral suppression (OR 1.50, 95% CI 1.02, 2.20). There was a significant smoking-by-time interaction for CD4 cell count (χ2(1) = 4.08, p < .05), with smokers less likely to have low CD4 count at baseline and 6-month follow-up, but more likely to have low CD4 count at 12-month follow-up. The results suggest that smoking may play a role in immunological functioning in HIV-infected substance users. ClinicalTrials.gov Identifier: NCT01612169.

Association of methadone dose with substance use and treatment retention in pregnant and postpartum women with opioid use disorder.

BACKGROUND: In non-pregnant individuals being treated for opioid use disorder (OUD) with methadone, doses ≥60mg per day are associated with improved treatment retention and decreased illicit opioid use. Although methadone remains the first line treatment for OUD in pregnant women, there are no studies replicating this finding in pregnancy. METHODS: We conducted a retrospective cohort study of 189 pregnant women treated with methadone for OUD from 2006 to 2013. Chart data collected included demographics, pregnancy dates, methadone doses, and urine drug screen (UDS) results. RESULTS: Treatment retention at delivery was significantly higher for subjects taking ≥60mg of methadone (90.1% v. 74.1% p<0.005), as was treatment retention at 60days postpartum (71.6% v. 37.0%, p<0.0001). Percent of UDS results negative for illicit substances during pregnancy was also significantly higher for subjects taking ≥60mg (71.5% v. 58.0%, p<0.04). There was no significant difference in UDS results in the first 60days postpartum (63.9% v. 68.1%). Generalized linear models showed a significant positive relationship between methadone dose and treatment retention at delivery (p<0.02) and at 60days postpartum (p<0.004) as well as a significant positive relationship between length of time in treatment and treatment retention at delivery (p<0.04) and at 60days postpartum (p<0.007). Maternal age and percent of negative UDS results were not predictive of treatment retention in either model and there was no significant interaction effect between methadone dose and percent negative UDS results. CONCLUSIONS: In this cohort, women taking ≥60mg of methadone during pregnancy were more likely to remain in treatment and to provide urine samples negative for illicit drugs. Multivariate modeling suggested a dose dependent response across the entire dose range, rather than a threshold effect at 60mg.
