A 2026 survey of 38 drug checking services found that Latin American programs faced a different operating reality than US programs: funding was a major barrier more often (80% vs. 54%), drug checking equipment was legally permitted less often (44% vs. 75%), and law enforcement confiscation of checking supplies was reported more often (38% vs. …
A 2026 prospective German aneurysm cohort found risky alcohol use in 4.6% of 954 intracranial aneurysm patients, and that exposure carried 2.00x higher adjusted odds of aneurysm rupture plus 3.26x higher adjusted odds of clinically severe aneurysmal subarachnoid hemorrhage. Research Highlights Risky alcohol was the main signal: drinking above the study threshold was independently associated …
Semaglutide is not close to being an approved cocaine-use-disorder medication, but a 2026 rat study gives the idea a more demanding preclinical test than ordinary self-administration experiments. After 5 days of treatment, rats shifted away from cocaine choice without losing total operant responding, which separates the result from a broad appetite-suppression artifact. Research Highlights Semaglutide …
A 2026 cross-species metabolism study found that eutylone, a synthetic cathinone stimulant sometimes sold as a “bath salt” or MDMA-like drug, inactivated CYP2D6 with Ki = 4.2 μM, kinact = 0.069 min-1, and inactivation efficiency = 1.64 x 10-2 min-1 μM-1 — a range the researchers described as comparable to MDMA. Research Highlights CYP2D6 was …
A 2026 population-based polysomnography study involving 1,206 adults found current smokers had 1.75x higher odds of worse obstructive sleep apnea severity than non-smokers or occasional smokers after adjustment for age and body mass index. Former smokers showed almost the same overall signal — 1.76x higher odds than never smokers — but that part of the …
A 2026 ABCD Study preprint involving 11,868 youth found stable time-ordered predictors of teen substance-use initiation, but the adjusted effects were small: most estimates ranged from −0.01 to 0.02 initiation-probability points per 1-SD predictor increase. Research Highlights Large ABCD panel: Wei et al. analyzed 11,868 youth with repeated observations and interval-level initiation outcomes for alcohol, …
A 2026 cross-sectional study in Moshi, Tanzania found that only 26 of 246 injury patients who drank alcohol, or 10.6%, had ever told a healthcare provider about their alcohol use.1 The calibration result was contrary to the prediction: measured alcohol stigma did not track disclosure, while alcohol-related consequences did. Research Highlights Disclosure was rare: among …
