Environmental enrichment found to weaken stress-triggered fentanyl relapse

Combating the opioid crisis relies on identifying new prevention strategies for problematic fentanyl use. In a collaboration between Washington State University and Washington University in St. Louis, researchers led by Jose Moron tested whether enriching a rat's environment can reduce fentanyl use and relapse.

People with chronic pain are twice as likely to smoke cigarettes

New research from the University of Kansas shows people who experience chronic pain tend to consume cigarettes and e-cigarettes at higher rates than others.

Brain pathways combine memory and reward to guide behavior

New research from the University of Maryland, Baltimore County (UMBC) reveals how two different parts of the brain's memory center team up in a key reward region to help mice-and likely humans-combine memories of places and contexts with the drive to pursue rewards.

Swapping passive screen time with mental activity may cut dementia risk

Research shows that mentally active sedentary behavior can reduce dementia risk, emphasizing the importance of daily cognitive engagement for brain health.

AI models may amplify bias in psychiatric aggression predictions

A first-of-its-kind study led by researchers at the Centre for Addiction and Mental Health (CAMH) has found that artificial intelligence (AI) models used to predict aggressive incidents in acute psychiatric care can reinforce and amplify existing social and structural inequities by overestimating the likelihood of aggression among already marginalized groups.

What happens in the brain on psychedelics? Scientists identify a common circuit pattern

Researchers combined 11 international resting-state fMRI datasets to map how psychedelic drugs reshape brain connectivity across cortical and subcortical circuits. The mega-analysis found a shared signature of stronger coupling between transmodal association networks and unimodal or sensorimotor systems, alongside selective and variable reductions in within-network connectivity.

Smoking shrinks key brain regions while cannabis shows weaker effects

The study highlights brain changes from tobacco use and calls for more research on cannabis, as its effects on brain structure remain inadequately understood.

Expanded Medicaid improved access to buprenorphine for opioid use disorder

Medicaid insurance expansions between 2017 and 2023 sharply increased access to medication treatment for opioid use disorder in a period when fatal overdoses continued to climb, according to Rutgers Health researchers.

Organ-on-chip model advances study of sexually transmitted infections

Sexually transmitted infections (STIs) not only impact an individual's health but also result in multibillion-dollar economic losses worldwide.

Semaglutide for weight loss was linked to a sharp drop in alcohol use in this case report

A 2026 case report describes a 34-year-old man with obesity and alcohol use disorder whose semaglutide treatment for weight loss was associated with a marked drop in drinking over 10 months, with his AUDIT score falling from 27 to 7 and alcohol use dropping from about 15 drinks per week to half a beer per month. The authors frame this as a promising but preliminary finding that adds to growing evidence on GLP-1 drugs and alcohol use, while also stressing that this was a single case and that better AUD screening in family medicine remains important.

Many US jails lack nearby access to opioid treatment programs, study shows

A new study led by researchers at Brown University School of Public Health found that more than half of U.S. jails are located at least a 30-minute drive from the nearest opioid treatment program - a distance that may make it harder for incarcerated people to receive methadone, a key medication for opioid addiction.

New brain circuit discovery offers hope for chronic pain treatment

A new map of a brain circuit specific to chronic pain suggests a promising route to treatment for the roughly 60 million Americans living with persistent pain, according to a study published in Nature.

Highly potent opioid shows potential as therapy for pain and opioid use disorder

Researchers at the National Institutes of Health (NIH) have identified a novel, highly potent opioid that shows potential as a therapy for both pain and opioid use disorder.

Brain pathway explains how stress drives alcohol-seeking behavior

Why do stressful moments so often push people toward habits like drinking? A new study from Texas A&M University offers one of the clearest answers yet, identifying a direct connection inside the brain that links stress to addiction‑related behaviors.

Attachment anxiety linked to higher risk of short video addiction

No matter where we turn on social media, short videos are everywhere. Repeated exposure to this brief, information-dense, and rewarding content stimulates the brain in a way that tells us the experience is pleasurable or satisfying.

Nicotine e-cigarettes outperform other methods for quitting smoking

A new analysis of existing studies co-led by a University of Massachusetts Amherst public health researcher finds that nicotine e-cigarettes consistently help adults quit smoking, a conclusion that emerges with striking agreement across nearly a decade of studies.

Study links social media addiction to worse student mental health and points to family as a key buffer

A study of 627 Saudi university students found that higher social media addiction was associated with more anxiety and depression, while family environment fully mediated those links in the statistical model. The findings suggest that supportive family relationships may help buffer the mental health burden associated with problematic social media use, although the cross-sectional design does not establish causation.

How behavior and biology combine to drive addiction

Genomic analyses reveal that addiction risk is influenced by both shared behavioral traits and specific biological factors, informing prevention and treatment.
