Rapid vs Standard Induction to Injectable Extended-Release Buprenorphine JAMA Network This industry-sponsored, multicenter, open-label randomized clinical trial with 729 participants, assessed if  rapid induction (RI) for initiating extended-release buprenorphine is as safe and effective as standard induction (SI) in individuals who inject opioids or use fentanyl.  RI was well tolerated and had higher retention than SI at extended-release buprenorphine injection 2 overall and in fentanyl positive participants. Administering the second extended-release buprenorphine injection 1 week after the first was well tolerated in both the RI arm and SI arm. These findings suggest support RI for extended-release buprenorphine induction in high-risk patients and demonstrate the feasibility of administering the first 2 doses at least 1 week apart.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

States With Substantial Increases In Buprenorphine Uptake Did So With Increased Medicaid Prescribing, 2018–24 Health Affairs Multiple federal policy changes since 2018 intended to increase buprenorphine prescribing in response to a persistent treatment gap for opioid use disorder (OUD) in the US. Anticipated national increases did not occur, but highly variable state-level trends provide important insights. This study used IQVIA data to examine all-payer and per payer prescribing across states during the period 2018–24.  Researchers found that highly disparate state-level changes suggest that federal policy impacts were mediated by state-specific factors. Medicaid’s key role in driving overall prescribing highlights the public health urgency of maintaining expansions and sustaining enrollment for the single adult population.    Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Ultra-processed food addiction in a nationally representative sample of older adults in the USA  Addiction Using a cross-sectional online and telephone survey of a nationally representative sample of older adults (aged 50–80 years) in the US, this study examined the prevalence of ultra-processed food addiction (UPFA) in older US adults and its association with various health domains.  It found that ultra-processed food addiction appears to be prevalent among older adults in the US, particularly among women who were in adolescence and early adulthood when the nutrient quality of the US food supply worsened. Addictive patterns of UPF intake appear to be associated with poorer physical health, mental health, and social well-being.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Alcohol Consumption Per Capita and Suicide: A Meta-Analysis JAMA Network Open  This meta-analysis that included 13 studies assessed if alcohol consumption per capita is associated with suicide mortality and, if so, does the association differ by sex. Researchers found that a 1-L increase in alcohol consumption per capita was associated with a 3.59% increase in the suicide mortality rate. There was no evidence of a sex difference in this association. These findings suggest alcohol consumption per capita may be a useful target to consider within comprehensive national suicide prevention strategies.    Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Measures of General Intelligence and Risk for Alcohol Use Disorder JAMA Psychiatry This male Swedish cohort study that included 573,855 participants assessed if there is an association between IQ and risk for alcohol use disorder, and if so, what is the nature of this association.  It found that IQ at age 18 years was associated with subsequent alcohol use disorder risk. Mendelian randomization analyses suggest a causal association, albeit with context-dependent differences; genetic liability for cognitive performance also predicted alcohol use disorder in a US-based sample. Results suggest that there was a clear impact of genetic liability for cognitive performance on alcohol disorder risk, but the association varies based on the sociocultural context.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Medications for Opioid Use Disorder Playbook Agency for Healthcare Research and Quality (AHRQ)  The AHRQ Integration Academy developed the Medications for Opioid Use Disorder Playbook as a practical guide for providing medications for opioid use disorder (MOUD) and immediate care for patients with OUD in primary care and other ambulatory care settings. It is interactive, web-based, and has the latest guidance, tools, resources, and examples that address key aspects of MOUD implementation. The MOUD Quick Start Guide covers the essentials of low-threshold care, while the balance of the Playbook offers more in-depth resources and guidance for those practices interested in working toward more comprehensive, whole-person care. The low-threshold approach ensures immediate access to MOUD, eliminating barriers for both patients and providers.    Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Cannabis Use During Pregnancy and Lactation American College of Obstetricians & Gynecologists Cannabis is the most commonly used illicit drug under U.S. federal law. With increasing social acceptability, accessibility, and legalization in many states, the prevalence of cannabis use among pregnant and lactating individuals has increased significantly. Substance use in pregnancy, including cannabis use, has been associated with adverse outcomes such as spontaneous preterm birth, low birth weight, and developmental delay. Clinicians should be aware of the possibility of pregnant and lactating patients' use of cannabis and be prepared to counsel and screen all patients and use evidence-based strategies to reduce cannabis use.  These include supportive home visits, psycho-behavioral strategies, or brief electronic or text messaging interventions to reduce cannabis use in pregnancy and the postpartum period to promote parental and newborn health.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM  

Contingency Management for Stimulant Use Disorder and Association With Mortality: A Cohort Study American Journal of Psychiatry This national retrospective cohort study found that veterans with stimulant use disorder who received contingency management (CM) were 41% less likely to die in the year following treatment initiation relative to matched comparison subjects. These findings provide the strongest real-world evidence to date that CM is associated with reduced all-cause mortality, underscoring its potential as a life-saving intervention in routine care. Results support expanding access to CM across healthcare systems and public health settings.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Machine learning– and multilayer molecular network–assisted screening hunts fentanyl compounds Science Advances Fentanyl and its analogs are a global concern, making their accurate identification essential for public health. This article introduces Fentanyl-Hunter, a screening platform that uses a machine learning classifier and multilayer molecular network that covers more than 87% of known fentanyls to select and annotate fentanyl compounds using mass spectrometry (MS). Fentanyl-Hunter identified fentanyl members in biological and environmental samples. During biotransformation, 35 metabolites from four widely consumed fentanyl derivatives were identified. Norfentanyl was the major fentanyl compound in wastewater. Retrospective screening of these biomarkers across more than 605,000 MS files in public datasets revealed fentanyl, sufentanil, norfentanyl, or remifentanil acid in more than 250 samples from eight major countries, indicating the potential widespread presence of fentanyl.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Evaluation of a Novel Patient-Centered Methadone Restart Protocol 🔓 JAMA Network Open Restarting methadone for patients who have had a gap in treatment is often a frustratingly slow process for both the patient and provider. This cohort study of individuals examined outcomes for patients of a public, safety-net opioid treatment program before (n=786 patients) and after (n=780 patients) implementation of a 2022 clinical protocol focused on individualized methadone restart doses based on opioid tolerance. Preimplementation restart doses were 32.8% lower than the last prior methadone dose, whereas postimplementation restart doses were only 3.4% lower than the last prior methadone dose. There was no significant change in patient safety (emergency department visits within 7 days after restart and all-cause mortality within 7 and 90 days after restart) or 90-day retention in care.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Injectable-Only Overlapping Buprenorphine Starting Protocol in a Low-Threshold Setting  JAMA Network Open  Injectable-only buprenorphine protocols are an exciting new strategy for buprenorphine initiation, particularly in the fentanyl era. This is a cohort study of 95 patients with moderate to severe opioid use disorder who received care in a low-threshold setting in Seattle. 79% of patients included in the study were experiencing homelessness or living in permanent supportive housing. Patients selected a long-acting injectable (LAI) buprenorphine initiation protocol which included three escalating doses of LAI buprenorphine over three days, with no sublingual buprenorphine and without cessation of fentanyl/opioid use. 75% of the patients completed the protocol, and 64% received a second monthly dose of LAI buprenorphine.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Association between housing status and mental health and substance use severity among individuals with opioid use disorder and co-occurring depression and/or PTSD  BMC Primary Care  This is a cross-sectional analysis of associations between housing status and mental health and substance use severity among primary care patients with co-occurring disorders. The study is a sub-analysis using data from the Collaboration Leading to Addiction Treatment and Recovery from other Stresses randomized controlled trial, which tested the Collaborative Care Model for primary care patients with OUD and co-occurring depression and/or PTSD. Of 797 patients in the study, 13% were currently unhoused, 24% were unstably housed, and 63% were stably housed. Those who were unhoused were on average younger and had not used prescribed MOUD in the past 30 days. The analysis found that being unhoused or unstably housed was significantly associated with higher PTSD symptom severity, depression symptom severity, opioid use severity, and opioid overdose risk behaviors compared to those who were stably housed.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Oral methadone versus sublingual buprenorphine for the treatment of acute opioid withdrawal: A triple-blind, double-dummy, randomized control trial  Drug and Alcohol DependenceResearchers compared oral methadone to sublingual buprenorphine for the management of acute opioid withdrawal. Patients at an inpatient drug treatment center in India were randomly assigned to receive either methadone or buprenorphine titrated over days 1-3 to control opioid withdrawal symptoms. Over days 4-10 medications were tapered and stopped by day 11. Completion of treatment was similar in both groups (83% methadone, 82% buprenorphine). Both subjective (SOWS) and objective (COWS) withdrawal symptoms decreased during the treatment, however the buprenorphine group had significantly greater withdrawal symptoms than the methadone group (p=0.009) at the end of treatment (day 10). Opioid craving also decreased in both groups with no significant difference between groups. Authors conclude that methadone is a safe and effective alternative to buprenorphine for management of opioid withdrawal.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM  

Implementation Gaps in US Syringe Service Programs, 2022  JAMA This study performed a cross-sectional analysis of the Syringe Services Programs in the US (SSPUS) dataset to determine implementation gaps. 613 syringe service programs (SSPs) included in the dataset were geocoded to county boundaries, which were then analyzed for urbanicity and SSP need (based on HCV mortality, HIV incidence, and drug overdose mortality). The study found that most high need counties did not have an SSP: 81.2% of high HCV need counties, 69.5% of high HIV need counties, and 75.7% of high overdose need counties did not have an SSP. SSPs were more commonly located in urban counties than suburban or rural counties. The study is limited in that not all SSPs are represented within the SSPUS database; however it highlights important implementation gaps.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Co-involvement of stimulants with opioids in North America: A 'silent epidemic’ Plos Mental Health The opioid epidemic unfolded in three distinct waves, with the latest being deaths attributed to illegally manufactured synthetic opioids. Using U.S. and Canadian data, this study reviews evidence for a 'silent epidemic' alongside the opioid epidemic that is characterized by the co-ingestion of stimulants including methamphetamine and cocaine leading to an increasing number of deaths. Trends for stimulant and opioid use were analyzed using Joinpoint regression and public interest in the substances was assessed via Google Trends. While stimulant use and its role in deaths are rising, public interest in stimulants has declined since its peak in 2004-05. Co-use leads to more deaths than either drug alone. Urgent strategies are needed to reduce harm and raise awareness among health professionals, policymakers, and the public about the dangers of stimulant-opioid co-use.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Did alcohol facilitate the evolution of complex societies?  Humanities and Social Sciences Communications This study tested the “drunk” hypothesis, which claims that alcohol promoted social bonding and cooperation, aiding the rise of complex societies. Using data from 186 non-industrial societies, they found a modest positive link between indigenous alcoholic beverages and political complexity, even after controlling for ancestry, environment, and agriculture. Results suggest traditional fermented alcohols provided social benefits that helped societal evolution. However, other factors like agriculture and religion were likely more effective drivers.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Disparities in Treatment and Referral After an Opioid Overdose Among Emergency Department Patients  JAMA Network Open This cohort study of 1,683 patients assessed if there are racial and ethnic disparities in treatment referral rates among patients in the emergency department (ED) with opioid overdose.  It found a statistically significant difference in the proportion of Black patients who received an outpatient treatment referral (5.7%) compared with White patients (9.6%). These findings suggest that Black patients presenting to the ED with opioid overdose may be less likely to receive outpatient treatment referrals, underscoring the need for targeted intervention and enhanced referral processes.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Prescriber-Level Changes in Buprenorphine Dispensing in the USA Before and After Federal Policy Changes Aimed at Increasing Prescribing Journal of General Internal Medicine This study used interrupted-time-series analysis to model prescriber-level trends in buprenorphine prescriptions after recent federal policy changes.  It found that the elimination of the waiver requirement to prescribe buprenorphine in December 2022 was associated with a significant increase in the number of buprenorphine prescribers, but a decrease in the mean number of patients and the mean number of prescriptions per prescriber. Changes in telehealth flexibilities and relaxed training requirements were largely not associated with prescribing changes. This study expands on prior research by providing further insight as to why waiver elimination has not increased the number of patients receiving buprenorphine, as expected.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM

Joint Clinical Practice Guideline on Benzodiazepine Tapering: Considerations When Risks Outweigh Benefits  Journal of General Internal Medicine The American Society of Addiction Medicine (ASAM), in collaboration with nine other medical societies and professional associations, developed evidence-based guidelines for tapering benzodiazepine (BZD) medications across various clinical settings. These guidelines were created using a modified GRADE methodology and a clinical consensus process, which included a systematic literature review and several targeted supplemental searches. The guidelines were also revised based on feedback from external stakeholders. Key recommendations include that clinicians should continually assess the risks and benefits of BZD use and tapering. They should engage in shared decision-making with patients and avoid abrupt discontinuation in individuals who may be physically dependent or at risk of withdrawal. Tapering strategies should be personalized and adjusted based on the patient’s response. Additionally, clinicians are encouraged to provide psychosocial support to help patients successfully taper off BZDs.   Read this issue of the ASAM Weekly Subscribe to the ASAM Weekly Visit ASAM
