ED Naloxone Need: 3.87M At-Risk Visits vs. 226K Overdoses

MHD featured image for emergency department naloxone distribution and opioid overdose prevention.

A 2026 emergency department claims analysis estimated 3.87 million United States ED visits in 2021 where take-home naloxone could have been clinically relevant, compared with 226,453 ED-treated opioid-overdose visits in the same database.1 The finding reframes naloxone distribution as an emergency-care workflow for overdose risk, polysubstance exposure, long-term opioid use, and patients who arrive after …

New Psychoactive Stimulant Deaths in Australia: 70 Toxicology Cases

Australian coronial data show that fatal poisonings involving new psychoactive stimulants and hallucinogens were rarely single-drug events. In 70 toxicology-confirmed deaths from 2007 through 2025, 92.9% involved other psychoactive drugs and 75.7% involved multiple stimulants or hallucinogens. Research Highlights Fatal cases were usually polysubstance cases: 65 of 70 deaths (92.9%) had psychoactive drugs beyond the …

Teen THC Increased Anxiety-Like Behavior in Adult Rats

A 2026 rat study found that 21 days of late-adolescent tetrahydrocannabinol (THC) exposure produced adult anxiety-like behavior in the elevated plus maze and weaker novel object recognition than vehicle exposure. The controlled animal result gives a biologically anchored model for why repeated high-THC exposure during development remains a real concern.1 Research Highlights Late-adolescent THC exposure …

SMART Texts Raised Diabetes Confidence in Schizophrenia

MHD featured image for SMART text messages and diabetes self-management in schizophrenia.

A 12-week text-message intervention for people with schizophrenia spectrum disorders improved diabetes self-management confidence and patient activation, but it did not yet move weight, HbA1c, physical activity, or psychiatric symptoms. SMART looked feasible and psychologically useful in this uncontrolled pilot; cardiometabolic outcomes need a full-scale randomized trial with longer follow-up.1 Research Highlights SMART was tested …

Early Clozapine in Schizophrenia: 34% Lower Relapse Risk

Stylized illustration of a stopwatch overlaying schizophrenia treatment-stage icons, representing the multi-year delay before clozapine is offered to patients who already meet treatment-resistance criteria.

Clozapine has been the most effective antipsychotic in schizophrenia for almost 40 years, yet it is still routinely held back until patients have failed multiple alternatives over many years — a “third-line, after years of failure” default that a 2026 Current Opinion review by Davani et al. argues is no longer supported by the evidence.1 …

Music During Ketamine Did Not Improve Resistant Depression

MHD featured image for ketamine psychotherapy, treatment-resistant depression, music, and psychedelic-like treatment context.

Adding music to ketamine psychotherapy failed to provide extra antidepressant benefit over matched non-music support in a 2026 randomized clinical trial (RCT; a study that assigns participants to groups by chance), even though the full 6-infusion ketamine-psychotherapy course was followed by large depression-score reductions. Research Highlights Music added no confirmed MADRS benefit: in the MUSIK …

GLP-1 Drugs Suppress Reward Feeding Through an Amygdala-Dopamine Circuit

MHD featured image for GLP-1 drugs, reward feeding, amygdala signaling, and dopamine circuitry.

GLP-1 drugs are usually described as appetite drugs, but a 2026 Nature mouse study mapped a more specific reward circuit: small-molecule GLP-1 receptor agonists suppressed palatable-food intake through Glp1r-expressing central-amygdala neurons that reduced dopamine release in the nucleus accumbens during high-fat-food retrieval.1 That mechanism makes binge-eating and substance-use hypotheses more plausible without turning an animal …
