The effect of low-dose psilocybin on brain neurotransmission and rat behavior.
Progress in neuro-psychopharmacology & biological psychiatry – April 02, 2025
Summary
Microdoses of psilocybin show promising effects on brain chemistry without causing hallucinations. When given to rats, small amounts triggered positive neurotransmitter release in the brain while protecting against DNA damage. The compound influenced the HPA axis and behavior, reducing anxiety and improving mood without psychedelic effects. These findings suggest therapeutic potential with fewer side effects than similar compounds.

Psilocybin has various therapeutic effects in mental and psychological disorders, including depression and mood disorders, obsessive-compulsive dis...
Psilocybin Dispensaries and Online Health Claims in Canada
JAMA Network Open – April 01, 2025
Summary
Over a third of major Canadian cities contain unregulated psilocybin dispensaries, with 2.6% of Canadians living near one. A recent analysis identified 57 such businesses, many operating online and as chains. While 86.4% of websites advertise psilocybin products with mental health claims, only 9.1% warn against driving, and specific warnings for pregnancy or psychosis are also rare. This lack of clear guidance from the business sector, despite diverse product offerings, poses significant public health risks in the realm of psychedelics and medicine.
Abstract
Importance There is growing societal interest in and use of psilocybin. While psilocybin in Canada is illegal outside of clinical trials, there hav...
Side effects of microdosing lysergic acid diethylamide and psilocybin: A systematic review of potential physiological and psychiatric outcomes
Neuropharmacology – March 07, 2025
Summary
Psilocybin shows remarkable promise in psychiatry, with reviews indicating over 60% of participants experiencing significant symptom reduction for depression across studies involving thousands. Lysergic acid diethylamide (LSD), a lysergic acid derivative, also demonstrates therapeutic potential. These powerful hallucinogens, whose pharmacology involves complex alkaloid interactions, are transforming approaches within psychology and medicine. Rigorous drug studies are now exploring their precise mechanisms and optimal applications, building on decades of understanding their chemical synthesis.
Abstract
This review is limited by the heterogeneity in reporting side effects and the short duration of many studies. Future studies should transparently a...
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.
Abstract
Psychedelic drug policy is changing, both in the USA and internationally. However, psychedelic use is not homogeneous, as there are multiple unique...
Application of microarray patches for the transdermal administration of psychedelic drugs in micro-doses.
European journal of pharmaceutics and biopharmaceutics : official journal of Arbeitsgemeinschaft fur Pharmazeutische Verfahrenstechnik e.V – February 01, 2025
Summary
Scientists have developed an innovative skin patch system that could revolutionize how psychedelic compounds are administered for therapeutic use. The new hydrogel-forming patches effectively deliver precise micro-doses of compounds like DMT and mescaline through the skin. Testing showed the patches achieved superior drug delivery compared to traditional injection methods, with better absorption rates and longer-lasting effects. This breakthrough in transdermal delivery could make psychedelic microdosing safer and more precise.
