Psychedelic single-dose therapy boosts cocaine abstinence in small trial

A randomized JAMA Network Open trial found that a single psilocybin dose, paired with psychotherapy, increased cocaine abstinence versus placebo among 36 participants, highlighting a potential new treatment since there are no FDA-approved cocaine-use meds. Experts say psilocybin may act as a catalyst for behavioral change via neuroplasticity, not as a maintenance drug. However, the small size, specific exclusions (no comorbid depression/anxiety), and recruitment nuances limit generalizability, and larger trials are needed. Notably, the study included a majority of Black participants, a first for psychedelic trials.

One Psilocybin Dose May Rewire the Brain for Weeks

A UCSF and Imperial College London study found that a single 25 mg dose of psilocybin increases brain entropy during the experience and is followed by lasting changes in brain connectivity for about a month, alongside reported boosts in psychological insight and well-being. The results suggest the psychedelic experience itself may drive durable mental health benefits and could inform optimized psilocybin-based therapies.

Tiny psilocybin study links intense trips to brain wiring changes

A small 28-participant study finds that after a 25 mg psilocybin dose, diffusion tensor imaging shows changes in water diffusion along neural fibers—especially in tracts linking the prefrontal cortex with other brain regions—with stronger trips associated with larger changes; about 70% of participants reported improved well-being 2–4 weeks later, suggesting psychedelic-induced brain plasticity, though results are exploratory and require replication in larger trials.

Psilocybin-assisted therapy shows potential to help people quit smoking

Psilocybin-assisted therapy shows potential to help people quit smoking

A BBC Health report describes a randomized trial where a single high dose of psilocybin (about 30 mg, with 10 CBT sessions) plus talk therapy led to significantly higher smoking cessation than nicotine patches: 52% abstinent at six months in 82 participants vs 25% in the patch group. These findings, echoing earlier smaller studies, suggest psychedelics can trigger neuroplastic changes and a shift in priorities that support quitting, and are driving a larger NIH-funded, multi-site follow-up study to confirm efficacy and understand mechanisms. However, experts caution the sample was small and not highly diverse, so results may not generalize, and long-term safety and durability remain to be seen.

Trump Signs Order to Fast-Track Psychedelic Therapies for Veterans

President Trump signed an executive order to accelerate research and access to psychedelic medicines—highlighting ibogaine—as potential treatments for serious mental illnesses and focusing on veterans with PTSD and suicide risk. The order directs cross‑agency collaboration (DOJ, HHS, VA, FDA), aims for faster regulatory review through science‑based pathways, and includes a $50 million federal funding commitment for ibogaine research and expanded access in licensed, hospital‑grade settings, all while maintaining rigorous safety standards.

Trump pushes fast-track reviews for psychedelic medicines

President Trump issued an executive order directing the FDA (and DEA) to fast-track reviews for psychedelic drugs and to establish a pathway for access to investigational psychedelics under FDA review, including granting priority review vouchers for three serotonin 2A agonists. Companies like Compass Pathways welcomed the move as a step toward faster, regulated access to psychedelic medicines for mental illness while maintaining scientific rigor.

Trump signs order to fast-track psychedelic research, including ibogaine

President Trump signed an executive order to ease federal restrictions on psychedelic research, including ibogaine, with a $50 million funding commitment and a pathway for ibogaine to be studied and used under the FDA's Right To Try for seriously ill patients. The FDA will also add three psychedelics to the National Priority Voucher program to accelerate reviews, while maintaining oversight and not legalizing the drugs. The move aims to spur new mental-health treatments but underscores safety concerns and the need for more robust clinical trials.

Five psychedelics converge on a common brain pattern, despite different chemistries

Five psychedelics converge on a common brain pattern, despite different chemistries

A multi-dataset analysis of over 500 brain scans from 267 participants shows psilocybin, LSD, mescaline, DMT, and ayahuasca produce a shared brain-state: weakened within-network connections and increased cross-network communication. This common neural signature could help standardize psychedelic research and guide future mental-health therapies, though the study used healthy adults and variations across datasets mean more work is needed.

Common neural fingerprint linked to five psychedelics, study suggests

A multinational reanalysis of 11 datasets (267 participants, 519 brain scans) across five psychedelics—psilocybin, LSD, mescaline, DMT and ayahuasca—identified a shared neural fingerprint: increased cross-network communication and selective reductions within certain networks across cortical and subcortical regions, suggesting a flattening of the brain's hierarchy. The pattern was most similar for psilocybin and LSD. While promising for understanding psychedelics and potential therapies, the study emphasizes the need for standardized, larger trials and notes that existing datasets used varied methods and doses.
