Persistent Tinnitus after Inhaled N,N-dimethyltryptamine (DMT)
Journal of Psychoactive Drugs – November 26, 2020
Summary
A unique case links hallucinogen use to persistent ear ringing. A 39-year-old male with a history of polysubstance dependence and depression developed tinnitus after a single DMT use, persisting for several months. The context included weekly LSD microdosing. Distress and anxiety over the condition prompted evaluation by audiology and medicine, including psychiatry. Psilocybin microdoses exacerbated symptoms on two occasions. While psychedelics are known for sensory changes, this case highlights a novel association in drug studies, prompting further psychological and medical inquiry into tinnitus mechanisms.

Converging pathways: shared brain circuitry engaged by monoaminergic antidepressants, ketamine and psilocybin
OpenAlex – May 30, 2025
Summary
Ketamine offers rapid relief for Major Depression, often within a single day, unlike traditional monoaminergic antidepressants requiring weeks. Neuroscience investigations in mice reveal a shared limbic brain circuit crucial for antidepressant efficacy. While Ketamine and high-dose Psilocybin, a hallucinogen, acutely activate key frontal brain regions, standard monoaminergic drugs and Psilocybin microdosing require chronic administration to achieve similar activation. This insight from Psychedelics and Drug Studies informs Psychiatry and Medicine, explaining delayed effects and advancing our understanding of neurotransmitter receptor influence on behavior in treating Major Depression.

Do undergraduates’ views of psychedelics relate to the context for psychedelic use?
Drug Science Policy and Law – March 01, 2025
Summary
Undergraduates largely perceive psilocybin and other hallucinogens similarly across diverse contexts, from clinical therapy to naturalistic use. A study of 277 psychedelic-naïve undergraduates (75.81% female) revealed limited distinctions in their views, despite the substances' varied chemical synthesis. When differences arose, clinical settings were viewed most positively, then microdosing. Only 19 of 79 comparisons showed significant variation in these perceptions. This highlights a need for greater social psychology understanding as policy shifts, impacting diverse academic themes from psychology to the aesthetics of archaeology.

Mood and cognition after administration of low LSD doses in healthy volunteers: A placebo controlled dose-effect finding study
European Neuropsychopharmacology – October 17, 2020
Summary
Microdosing with LSD can enhance mood and cognitive performance, as shown in a study with 24 healthy participants. A dose of just 5 mcg improved positive mood by 33% and reduced attentional lapses by 25%. Higher doses, particularly 20 mcg, further boosted friendliness and arousal while introducing some confusion and anxiety. Notably, the most significant effects on subjective experience were observed at 20 mcg. This suggests that even minimal doses of LSD may selectively improve mood and cognition without overwhelming side effects.

There is a popular interest in microdosing with psychedelics such as LSD. This practice of using one-tenth of a full psychedelic dose according to ...
Psilocybin improves novel object recognition in a rat model of Fragile X Syndrome through the modulation of the BDNF/TrkB signaling pathway
Neuropsychopharmacology – February 13, 2026
Summary
Psilocybin microdosing significantly improved object recognition memory in a rat model of Fragile X Syndrome (FXS), the leading inherited cause of intellectual disability. In a sample of Fmr1-Δexon 8 rats, psilocybin normalized mature BDNF levels and enhanced TrkB signaling in the prefrontal cortex, crucial for synaptic plasticity. Notably, this improvement occurred independently of classical serotonergic receptor activation, suggesting that BDNF/TrkB-AKT pathways are key to its effects. These findings position psilocybin as a promising therapeutic approach for neurodevelopmental disorders like FXS and autism spectrum disorder.
