Charting the Decline of the Fourth Wave: US Overdose Deaths by Race, Ethnicity, and Substance Involvement

Between 2023 and 2024, the United States experienced a significant 24.4% decline in overdose death rates driven by a sharp drop in fentanyl-involved deaths, marking the first decrease in the "fourth wave" of the crisis, though substantial racial disparities persist with American Indian/Alaska Native and Black individuals continuing to face the highest mortality rates.

Effectiveness of Noninvasive Brain Stimulation Protocols on Drug Craving and Consumption/Relapse in Substance Use Disorders: A Systematic Review and Meta-analysis of 208 Clinical Trials and 36 Protocols

This systematic review and meta-analysis of 208 clinical trials demonstrates that noninvasive brain stimulation techniques, particularly high-frequency TMS and tES targeting the frontopolar and DLPFC regions, produce medium-to-large effects in reducing drug craving and consumption in substance use disorders, with high-frequency deep TMS using the H4 coil showing the strongest efficacy.

Cannabis Co-Use and Endocannabinoid System Modulation in Tobacco Use Disorder: A Translational Systematic Review and Meta-Analysis

This translational systematic review and meta-analysis reveals that while naturalistic cannabis co-use significantly hinders tobacco cessation, preclinical and clinical evidence supports targeted modulation of the endocannabinoid system, particularly with cannabidiol (CBD), as a promising therapeutic strategy for treating tobacco use disorder.

Estimating the Daily Milligrams of Morphine Equivalent of Illicit Fentanyl Use in Los Angeles: Clinical and Epidemiological Implications

This study utilizes Los Angeles drug checking data to estimate that individuals consuming illicit fentanyl ingest daily doses equivalent to thousands of milligrams of oral morphine, a magnitude far exceeding clinical guidelines that likely drives high overdose mortality and extreme opioid tolerance.

Racial and Ethnic Differences in Pregnancy Associated Overdose Mortality in the United States, 2016 to 2022

This study analyzes US mortality data from 2016 to 2022 to reveal that pregnancy-associated overdose deaths have surged across racial and ethnic groups, with a particularly steep increase among non-Hispanic Black individuals that has widened the mortality disparity relative to non-Hispanic White individuals, underscoring the urgent need for targeted prevention strategies.

Salient cue reactivity and eating behaviours in ex-smokers, abstinent alcohol use disorder and obesity

This neuroimaging study reveals that abstinent ex-smokers exhibit heightened brain reactivity to both food and drug cues compared to those with alcohol use disorder or obesity, suggesting that persistent neural sensitivity to high-energy foods may drive post-cessation weight gain, while a distinct sweet taste preference endophenotype appears specific to alcohol use disorder.

Suicidality and Drug Use Behavior Among Perinatal Individuals in Recovery

This study of perinatal individuals in recovery from substance use disorders found that a history of suicidal thoughts and behaviors is significantly associated with increased cravings for opioids, higher rates of recent cannabis use, stronger correlations in nicotine use, and comorbid mental health conditions, while also revealing racial disparities in overdose history and opioid cravings.

Integrating Screening and Clinical Interviews: Advancing the Assessment of Exercise Addiction in Athletes

This study demonstrates that while high scores on the Exercise Dependence Scale are common among endurance athletes, only a subset meet the stricter ICD-11 criteria for clinical addiction, highlighting the necessity of combining quantitative screening with structured clinical interviews to distinguish normative high involvement from pathological exercise addiction.

Brain penetrant calcium channel blockers do not reduce alcohol consumption: Converging results from two large independent cohort studies using electronic health records

Despite compelling genetic and preclinical evidence, two large, preregistered observational studies using electronic health records found that initiating brain-penetrant L-type calcium channel blockers does not reduce alcohol consumption compared to non-penetrant alternatives or unexposed controls, indicating these drugs are not effective for repurposing in alcohol use disorder treatment.

Optimising supervised machine learning algorithms predicting cigarette cravings and lapses for a smoking cessation just-in-time adaptive intervention (JITAI)

This study found that while machine learning models can detect smoking lapse risks, their modest overall performance and high inter-individual variability suggest that reducing assessment frequency or simplifying predictors does not consistently improve outcomes, indicating that such algorithms are best used in combination with rules-based approaches rather than as standalone solutions for just-in-time adaptive interventions.
