This Week in the ASAM Weekly

Two publications this week are part of special issues in their respective journals. The is a first-of-its-kind on brain development, and the journal  includes 17 publications written by the teams involved with the design and implementation of specific components of the study. 

A six-paper series in  calls for changing the narrative around suicide prevention, and focuses on the role of social and commercial determinants of health. The authors advocate for further expanding current prevention models beyond individual risk factors and mental health interventions but articulate this in a way that will resonate well with those interested in addiction prevention - suicide is more than a mental illness. 

Keeping that in mind,  has published (yet again) an article that tries to say there is an “us against them” view about the definition of addiction, but there isn’t. No one is “discounting the many genetic, social, environmental and other factors” involved with addiction. So, it’s ok for us to all agree that addiction is a brain disease while also agreeing it is a disease of not only the brain.  

A profile of William Cope Myers demonstrates this well as he describes the complexity of opioid addiction after more than a decade of recovery from crack cocaine. When his approach to recovery, at first, did not work the second time around, buprenorphine did, and from there his recovery flourished (). &²Ô²ú²õ±è;

So, while we better understand the roles of social and commercial determinants of health, prenatal and protective factors of child development, and dialogue about the definition of addiction, we will continue to make progress in understanding the discontinuation of MOUD (), the impact of cannabis laws on mental health treatment (), and even the role of ketamine in buprenorphine induction (). &²Ô²ú²õ±è;

 If it all seems very complicated, that's because it is. The brain is the only existential organ we’ve got, and addiction is one of its diseases.

Lead Story

JAMA Network Open

This cross-sectional study of 9,438,716 commercially insured patients examined if access to cannabis, via medical or recreational legalization, is associated with changes in the dispensing of prescription medications to treat mental health disorders. Researchers found statistically significant reductions in benzodiazepine dispensing after increases in both medical and recreational cannabis access. However, evidence suggests increases in other types of psychotropic dispensing. The study suggests that cannabis laws may be significantly associated with the population-level use of prescription drugs to treat mental health disorders, although the associations vary by drug class and state.

Addiction

This retrospective cohort study of patients in the Veterans Health Administration system examined opioid overdose rates in the year after initiation and early discontinuation (<180 days) of medications for opioid use disorder (MOUD) by type: buprenorphine (BUP), methadone (MET), and extended-release naltrexone (XR-NTX). Researchers compared overdose rates with expected overdose rates, if no patient discontinued MOUD, and found that overdose rates were significantly higher than predicted (9% vs 3.9%) for patients taking BUP. Overdose rates were higher than expected for XR-NTX as well, but not statistically significant. Early termination of BUP was associated with higher risk of overdose. The expected overdose rate among patients on MET was 8.4%, which the authors suggest may be because those who started on MET had more severe OUD. 

 

Journal of Addiction Medicine

The authors describe naloxone stigma based on “risk compensation beliefs” that the safety afforded by naloxone allows increased opioid use and decreases treatment seeking. These beliefs are common among the general public, physicians, pharmacists, police officers, and EMTs. This study surveyed 195 people who use drugs (PWUD) regarding stigma towards naloxone and MOUD. About 1 in 5 PWUD reported risk compensation beliefs regarding naloxone. Cis women were less likely to have naloxone stigma than cis men. Naloxone stigma was associated with nonopioid substance use, recent stimulant use, no experience with overdose, and fewer recovery attempts. MOUD stigma had similar trends so that stigma for naloxone and MOUD were highly correlated. Depression symptoms were associated with MOUD stigma but not naloxone stigma. The authors suggest that PWUD receive more overdose and naloxone education.

Alcohol and Alcoholism

Australia’s pharmaceutical benefit supports treatment of AUD with naltrexone and acamprosate. This study looked at benefit data between 2006 and 2023 to assess the use of these pharmacotherapies for AUD. Prescriptions for naltrexone made up 45%, acamprosate 43%, and 12% were prescribed both concurrently. Over the 17 years studied, individuals treated with naltrexone increased 2.6 fold with only modest increases for acamprosate. Treatment guidelines suggest 3-6 months of medication; however, 79% completed only 1 month, and only 5% completed 3 months. Using estimates of prevalence of AUD in Australia, it was estimated that only ~3% of individuals with AUD receive pharmacotherapy. Naltrexone individuals were more likely to refill prescriptions and to complete the recommended 3-month treatment. The authors conclude that naltrexone dispensing has increased substantially; however, use of pharmacotherapy for AUD remains low.

The Lancet Public Health

Suicide is prevalent in all countries and is largely preventable. The causes of suicide are multiple and varied. Social determinants of suicide are crucial, but to date, these have received insufficient policy attention. This paper, which is the first in a Lancet Series on taking a public health approach to suicide prevention, argues for a major change in the way we think about suicide and its prevention. The authors present a public health model that emphasizes the broad social determinants of suicide and describe a framework through which these might be addressed. They also argue for a policy reset that would take national suicide prevention strategies to the next level. Such policies would become whole-of-government endeavors that tackle major social determinants of suicide at their source. High-quality data and methodologically rigorous evaluation are integral to this public health approach.

Developmental Cognitive Neuroscience

This article gives an overview of the HEALthy Brain and Child Development (HBCD) Study, which is featured in a special issue of Developmental Cognitive Neuroscience along with 17 other articles describing various components of the HBCD study. The authors note that exposure to a variety of hazards and events prenatally and in early life can affect brain development. Specifically, 10% of births are exposed prenatally to risky levels of alcohol and drugs. Protective factors, such as stable caregiving, will be included. Researchers plan to recruit over 7,000 mother/infant pairs from 27 sites nationwide and follow child development to age 10 years. Prenatal substance use exposure will make up 25% of the HBCD cohort. Assessments will include neurobehavioral performance, surveys, neuroimaging, EEG, biospecimens, and wearable biosensors. Data will be made available yearly.

Translational Psychiatry

There is prior evidence that oxytocin (OXT) has anxiolytic effects, reducing subjective and cortisol responses to psychosocial stressors, but this response is moderated among those with nicotine dependence. In this study, researchers examine the response to OXT in smokers and non-smokers during psychosocial stressors utilizing functional neuroimaging, salivary cortisol levels, and subjective responses to better understand this relationship. The authors found the anterior right superior temporal gyrus (rSTG) to be a site of interaction, with an altered response to OXT among smokers. In addition, they found when transcranial direct current stimulation (tDCS) was applied to the rSTG, the anxiolytic effects of OXT were restored. The authors note these findings can help support the development of interventions among smokers.

Addiction Science and Clinical Practice

Buprenorphine-precipitated opioid withdrawal (BPOW) can be a barrier to buprenorphine induction, and while new strategies including low-dose and rapid high-dose initiation have been developed, they may not work for everyone. Ketamine has been used in inpatient settings intravenously to relieve opioid withdrawal symptoms, but its use in outpatient settings is not feasible. In this case series, researchers examined sublingual ketamine use along with buprenorphine induction and its impact on BPOW and initiation. Among 37 patients prescribed ketamine, 24 took it, 16 completed buprenorphine initiation, and 12 were retained in treatment at 30 days. In addition, patients reported that the ketamine relieved opioid withdrawal symptoms and BPOW symptoms without any significant side effects.
