This Week in the ASAM Weekly

 

The public often views e-cigarettes and cannabis as safer alternatives to tobacco but as our lead article from Heart Rhythm considers, the harms specifically toward cardiovascular health could be equivalent. In this study, rats were exposed to relatively modest amounts of tobacco, nicotine, and cannabis products over eight weeks and found to have similar pathophysiological changes. Similarly, there is concern that prenatal exposure to cannabis can produce similar maternal and infant outcomes as seen with tobacco. A study representing over 1.2 million Canadian pregnancies found an increased likelihood of preterm birth, low birth weight, small-for-gestational age and congenital anomalies in cannabis-exposed births (Plos One). 

Through the lens of the AIDS epidemic, a commentary in the Journal of Addiction Medicine explains how grief and trauma are experienced in the OUD community. The NIAAA turned 50 (in 2020) and Dr. Koob reflects on its history and the significant advances that have been made (Alcohol Research Current Reviews). A comparison of minimally disruptive OUD care with the current state of addiction care shows how much further we can go (Journal of General Internal Medicine), while a study on “secret shoppers” calling local pharmacies to assess buprenorphine capacity shows that we may not have gone as far as we think (Addiction Science & Clinical Practice).

Lastly, 42 CFR Part 2 is overdue for an upgrade. The US Health and Human Services Department has announced several important changes to the law and is welcoming public comment (HHS.gov).

Lead Story

Increased vulnerability to atrial and ventricular arrhythmias caused by different types of inhaled tobacco or marijuana products 🔓

Heart Rhythm

This study investigated the cardiovascular effects of exposure to tobacco smoke, vape aerosol, heated tobacco products, marijuana smoke, THC-free marijuana, or air (placebo control). Rats were exposed to a single 5-minute session 5 days a week for 2 months. This exposure was judged to be similar to a single smoking or vaping session a day. Left ventricular dilation and reduction in LV ejection fraction was seen in all non-air groups along with reduction in heart rate variability. Both atrial fibrillation and ventricular tachycardia were more easily induced in all non-air groups. Decrease in microvessel density and severe interstitial fibrosis was seen on histology from all non-air groups. The authors conclude that all tobacco products (including vaping) and marijuana carry substantial risk of cardiac disease.

Research and Science 

Cannabis use in pregnancy and maternal and infant outcomes: A Canadian cross-jurisdictional population-based cohort study 🔓

Plos One

With the recent legalization of cannabis in Canada, this population-based study investigated the effects of prenatal cannabis use on maternal and newborn outcomes, and modification by infant sex. The prevalence of cannabis use in the studied cohort was approximately 2%. Prenatal cannabis use was found to increase the likelihood of preterm birth, low birth weight, small-for-gestational age, and major congenital anomalies with prenatally exposed female infants showing evidence of increased susceptibility. Additional measures are needed to inform the public and providers of the inherent risks of cannabis exposure in pregnancy.

 

Outcomes of Patients with Opioid-Related Diagnoses in Acute Coronary Syndrome: a National Inpatient Sample-Based Analysis.

Journal of General Internal Medicine

Although epidemiological studies point to increased risk of acute coronary syndrome (ACS) in opioid users, in-hospital management and outcomes are unknown for this population when presenting with ACS.  Using the National Inpatient Sample database, this study found that compared to patients without opioid-related diagnoses (ORD) presenting with ACS, patients with ORD were younger with fewer cardiovascular risk factors. However, in-hospital mortality was higher in patients with ORD presenting with ACS. Patients with ORD were more likely to experience in-hospital cardiac arrest and less likely to undergo angiogram or percutaneous coronary intervention.

 

Availability of medications for opioid use disorder in outpatient and inpatient pharmacies in South Florida: a secret shopper survey 🔓

Addiction Science & Clinical Practice

This study investigated the availability of buprenorphine products in pharmacies in South Florida. Both outpatient (n=200) and inpatient (n=25) pharmacies were surveyed by telephone. Only 38% of outpatient pharmacies had any buprenorphine in stock and only 55% of those without buprenorphine were willing to order it. There was a significant difference in availability by county, with the least availability in Miami-Dade at 27% and the most in Palm Beach at 47% (p=0.04). More inpatient pharmacies had buprenorphine (88%) but many (55%) had implemented restrictions beyond federal regulations. The most common restriction was to providers of specific specialties. The authors conclude that there are significant pharmacy-related barriers to treatment of OUD.

The United Kingdom's Psychoactive Substances Act 2016. Where are we now? 🔓

Drug Science, Policy and Law

The Psychoactive Substance Act (PSA) prospectively banned newly synthesized chemicals with psychoactive effects in the United Kingdom. In this review, the author summarizes changes in sales and mortality due to novel psychoactive substances (NPS), though the author does note significant limitations in the data. While there was a clear decrease in open sales of NPS after the implementation of the PSA, there was a shift to street-level and online sales, which is harder to capture. In addition, while there was an initial decrease in deaths associated with NPS, those numbers increased subsequently, potentially due to an increased potency of NPS. Also of note, while looking specifically at stimulant NPS, there was no decrease in associated deaths, but there was a concurrent increase in deaths due to conventional stimulants. 

 

Envisioning Minimally Disruptive Opioid Use Disorder Care 🔓

Journal of General Internal Medicine

Many US health systems and policies produce unwarranted, inflexible, and punitive practices that create life-threatening barriers to care for people struggling with substance use disorders. Minimally disruptive medicine (MDM) is a framework that focuses on achieving patient goals while imposing the smallest possible burden on their lives. A minimally disruptive OUD framework could inform improvements in clinical practice, health system redesign, payment reform, and policy change. That means incorporating factors such as racism, housing, transportation, income, technology, and culture into care.

 

NIAAA 50th Anniversary Festschrift: From the Editor 🔓

Alcohol Research Current Reviews

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) was created 50 years ago by an act of Congress with a mission to conduct health education, training, research, and planning programs for the prevention and treatment of alcohol-related problems. In this editorial, the author looks back at some of the accomplishments in those 50 years and references several articles in the Festschrift topic series. Some of the major accomplishments include the epidemiology of alcohol use, genetic basis of alcohol use disorder (AUD), effects of alcohol on adolescent brains, neurobiology in recovery from AUD, behavioral interventions and medications for AUD, effects on the fetus, and finally alcohol-associated liver disease. While these are not all the accomplishments in the last 50 years, they highlight some of the successes of the NIAAA. 

 

Grief at the Heart of the Opioid Overdose Crisis: Past Lessons and Present Implications

Journal of Addiction Medicine

The AIDS epidemic provides a framework for understanding the impact of grief in the opioid overdose crisis. Today, most clinicians do not routinely discuss the impact of overdose losses or consider the role of grief in treatment outcomes with their patients with OUD. This grief places patients at greater risk of returning to use  and losing control over their use, resulting in increased risk of overdose or suicide. Direct, tangible measures can be implemented, including the Brief Grief Questionnaire, referral to psychotherapy, or antidepressant medication. Clinicians should also heed worsening OUD by enhancing prevention efforts, titrating medications to control cravings, and employing harm reduction strategies.
