ACS Omega – September 16, 2025
Summary
Sample 2C, derived from the stem bark of *Mimosa tenuiflora*, yielded 3.45% DMT from 5 g of powdered material, equating to approximately 0.172 g of pure compound. Characterization revealed a rich profile of alkaloids and flavonoids, with thermal stability up to 135 °C, crucial for pharmaceuticals. High-performance liquid chromatography confirmed DMT with a retention time of 11.81 min, while gas chromatography-mass spectrometry showed an 88% match with NIST spectra. Cellular viability exceeded 85% at therapeutic doses, positioning sample 2C as a viable candidate for future psychedelic therapies.
Abstract
N,N-Dimethyltryptamine (DMT), a plant-derived tryptamine alkaloid, has attracted growing interest due to its therapeutic potential in treating ment...
Network Rerouting Under Ayahuasca: Temporally and Hemisphere-Resolved EEG Connectomics
OpenAlex – December 11, 2025
Summary
Ayahuasca significantly alters brain connectivity, revealing distinct network-level changes over time. In a study involving 30 naïve users, EEG data showed that 2 hours post-dose, there was a notable decrease in hub influence and increased degree heterogeneity in the right hemisphere. Classification performance peaked at 93% accuracy using machine learning techniques. Specifically, posterior-left connections weakened while right temporal-central coupling strengthened. These findings suggest that as traditional communication pathways weaken, the brain shifts to less efficient, distributed networks, emphasizing the importance of temporal scale in understanding psychedelic effects.
Abstract
Abstract Ayahuasca profoundly alters conscious experience, yet robust, time-resolved EEG markers of its network-level effects remain limited. We co...
Ketamine psychotherapy for heroin addiction: immediate effects and two-year follow-up.
Journal of substance abuse treatment – December 01, 2002
Summary
A powerful insight into addiction treatment reveals that psychotherapy paired with a specific high dose of ketamine dramatically boosts long-term recovery. Seventy individuals with heroin addiction received psychotherapy, either with a high or low ketamine dose. Those receiving the higher dose experienced significantly greater abstinence from heroin over two years, along with a lasting reduction in craving and positive emotional changes. This highlights the potential of psychedelic-assisted therapy for lasting success.
Abstract
Seventy detoxified heroin-addicted patients were randomly assigned to one of two groups receiving ketamine psychotherapy (KPT) involving two differ...

Development of the Japanese version of the Ego‐Dissolution Inventory (EDI)
Neuropsychopharmacology Reports – March 13, 2024
Summary
Psychedelics show promise for mental health, often inducing a unique "ego-dissolution" experience. To better understand this in a human context, a new Japanese version of the Ego-Dissolution Inventory (EDI) was developed. Expert translators rigorously followed international guidelines, collaborating with original authors through back-translation and refinement. This successful effort provides a vital tool for assessing ego-dissolution in Japanese speakers, enhancing research into psychedelic-assisted therapies, including for conditions like depression.

Transient Elevation of Plasma Glucocorticoids Supports Psilocybin-Induced Anxiolysis in Mice
ACS Pharmacology & Translational Science – August 02, 2023
Summary
Psilocybin's long-term anxiolytic effects stem from a temporary stress hormone surge, not its hallucinogenic properties. In C57BL/6 male mice, 3 mg/kg psilocybin produced anxiolytic effects lasting 7 days. This pharmacology was blocked by a glucocorticoid receptor antagonist, an antiglucocorticoid, or suppressing corticosterone. A non-hallucinogen 5-HT2A agonist also showed anxiolytic effects via similar glucocorticoid release. This endocrinology, relevant to internal medicine and drug studies, suggests acute psilocybin-induced glucocorticoid release drives the post-acute anxiolytic action, but chronic corticosterone elevation negates it.
Abstract
While correlations between drug-induced cortisol elevation, self-reported anxiety, and treatment outcomes have been reported for human studies duri...
