Psilocybin beats nicotine patches 40.5% vs 10% for quitting smoking

Key Findings

🧠 Female rats show heightened sensitivity to psychedelic 5-MeO-DMT

• Female rats demonstrated markedly enhanced sensitivity to low-dose 5-MeO-DMT (0.1 mg/kg), showing extensive brain activity changes that were largely absent in males at the same dose

• Brain imaging revealed peak effects occurred within the first 10 minutes after injection, aligning with the compound's rapid-acting therapeutic potential

• This represents the first fMRI study of 5-MeO-DMT in any species, revealing previously unknown sex differences in psychedelic response

🕊️ Psychedelics linked to reduced fear of death

• Meta-analysis of 8 studies found psychedelics associated with moderate-to-large reductions in death anxiety (Cohen's d = 0.70)

• Mystical experiences during psychedelic sessions were particularly associated with decreased death anxiety

• Effects were stronger in clinical settings compared to general population use

🌿 Scientists discover magic mushroom's closest wild relative in Africa

• Researchers identified Psilocybe ochraceocentrata as the closest wild relative to cultivated Psilocybe cubensis, last sharing a common ancestor approximately 1.5 million years ago

• Both species are associated with large herbivore dung, suggesting their common ancestor was already adapted to this ecological niche

• DNA analysis challenges previous assumptions about the geographic origins and evolutionary history of psychedelic mushrooms

👶 Ketamine shows promise for PTSD patients in real-world settings

• 202 real-world patients with PTSD reported improvements across multiple trauma symptoms after ketamine treatment

• Patients with PTSD had more severe depression, anxiety, and sleep problems before treatment but responded just as well as those without PTSD

• Most PTSD patients received additional psychotherapy, though improvements were also reported by those receiving ketamine alone

🧪 Ayahuasca linked to improved memory and cognitive flexibility

• Systematic review of 16 studies found short-term improvements in working memory and cognitive flexibility following ayahuasca use

• Long-term studies generally found no cognitive deficits, with some reporting enhanced memory and executive function

• Social cognition studies showed increased empathy and emotion recognition, though experimental studies only observed faster reaction times

⚠️ Hallucinogen use linked to complex clinical outcomes in adolescent psychosis

• 14.3% of adolescents with early-onset psychosis had used hallucinogens, with rates varying widely across studies

• Hallucinogen use was consistently associated with polysubstance use, suicidality, conduct disorder, and reduced educational attainment

• In general population studies, associations between hallucinogen use and psychotic symptoms were weak and largely disappeared after accounting for other drugs and genetic vulnerability
