Teen Vaping in Thailand: 17.6% Considered E-Cigs Despite Ban

MHD featured image for teen vaping tendency, e-cigarettes, and youth nicotine risk in Thailand.

A 2026 cross-sectional school study involving 1,848 rural Thai teenagers found that 17.6% reported a tendency to use e-cigarettes, even though Thailand bans e-cigarette sale and importation.1 The strongest adjusted correlate was having ever considered smoking cigarettes: those teenagers had 6.71 times the odds of e-cigarette use tendency compared with teenagers who had never considered …

Ebselen Failed to Reduce Impulsivity in 130 Healthy Adults

MHD featured image for ebselen and impulsivity placebo trial.

A double-blind placebo-controlled trial found no evidence that ebselen reduced impulsivity in 130 healthy adults: 66 received ebselen, 64 received placebo, and the 1,800 mg 2-day regimen did not improve motor impulsivity, reflection impulsivity, or delay discounting.1 The more interesting calibration is that several trait-impulsivity interactions ran opposite the secondary prediction, weakening the idea that …

Cannabis Abstinence: Frequent Use Did Not Increase Acute Pain in 75 Adults

MHD featured image for cannabis abstinence, THC exposure, and acute pain sensitivity.

A 2026 laboratory study found no detectable acute-pain increase in frequent cannabis users after at least 12 hours of biochemically verified abstinence. Frequent users had higher THC exposure and higher plasma cannabinoid markers, but pain threshold, pain tolerance, and pain ratings did not differ from occasional users.1 Research Highlights 75 healthy adults were tested: Pabon …

P2X7 Receptors in Depression: ATP-Inflammation Target

MHD featured image for P2X7 receptors and depression inflammation pathways.

A 2026 review in Purinergic Signalling argues that P2X7 receptors are one of the clearest molecular bridges between stress, ATP danger signaling, microglial inflammation, NLRP3 inflammasome activation, reduced BDNF, and new antidepressant drug targets.1 Research Highlights P2X7 is the lead receptor: Mattova et al. reviewed 7 ATP-gated P2X receptor subunits, with P2X7 carrying the strongest …

Bumetanide PROMset Study: 83% Improved in 1 Sensory-Related Domain

MHD featured image for bumetanide and sensory-related parent-reported outcomes in neurodevelopmental disorders.

A 2026 medRxiv preprint using parent-cocreated sensory-related outcome measures found that 83% of children and teens improved on at least 1 PROMIS domain during 6 months of bumetanide treatment.1 The result is interesting, but the unmasked single-case design means the strongest claim is about sensitive outcome tracking, not definitive bumetanide efficacy. Research Highlights Most participants …

Psilocybin First Use Changed Brain Signals for 1 Month

MHD featured image for first-time psilocybin use, brain entropy, MRI changes, and psychological insight.

A 2026 mechanistic study involving 28 healthy adults found that a single 25 mg psilocybin session changed acute brain entropy, psychological insight, well-being, cognitive flexibility, and some MRI-derived white-matter signals for up to 1 month. Research Highlights Acute brain entropy rose clearly: 25 mg psilocybin increased Lempel-Ziv complexity (LZc; a measure of signal irregularity) at …

Psilocybin Reduced Fish Aggression Bursts in Rivulus Study

MHD featured image for psilocybin effects on aggression and activity in a mangrove rivulus fish model.

A 2026 study involving 32 adult mangrove rivulus fish pairs found that 3,000 µg/L waterborne psilocybin reduced movement and aggressive swimming bursts, but the result belongs in animal behavioral pharmacology, not in human aggression treatment claims.1 Research Highlights Fish movement decreased: psilocybin produced a treatment-by-time interaction for time spent moving (p = 0.006), with a …
