- Consciousness and complexity: a consilience of evidence (review, more on consciousness with mention of psychedelics)
- Consciousness in active inference: Deep self-models, other minds, and the challenge of psychedelic-induced ego-dissolution (theory of consciousness and rebuttal to psychedelic-induced ego-dissolution as counterargument, “I argue that an account of consciousness in the predictive brain is within reach via recent accounts of phenomenal self-modelling in the active inference framework. The central claim here is that phenomenal consciousness is underpinned by ‘subjective valuation’—a deep inference about the precision or ‘predictability’ of the self-evidencing (‘fitness-promoting’) outcomes of action.”)
- Psychoactive Substance Use Among Individuals with Chronic Spinal Cord Injury: Patterns and Characteristics (n=4577, survey, 24% used psychoactive substances in population with spinal cord injury (SCI), but focus is on cannabis use, not psychedelics)
- Neural circuit dynamics of drug-context associative learning in the hippocampus (pre-print, in mice, “we reveal that drug-context associations for psychostimulants and opioids are encoded in a subset of hippocampal neurons … dissociative drug ketamine blocked both the drug-induced changes to hippocampal coding and corresponding drug-seeking behavior”)

- A novel method for predicting human cardiotoxicity without animal testing (thesis, covers ibogaine toxicity)
- Ketamine ameliorates depressive-like behaviors in mice through increasing glucose uptake regulated by the ERK/GLUT3 signaling pathway (in mice, “ketamine mitigated depressive-like behaviors in female mice by activating the ERK/GLUT3 signal pathway, which further increased glucose uptake in the prefrontal cortex“)
- Investigation of MDMA Inhibitory Effect on CytochromeP450 3A4 in Isolated Perfused Rat Liver Model Using Tramadol (in rats, “the regular doses of MDMA cannot inhibit the CYP3A4 activity.“)

- Serotonin transporter availability, neurocognitive function and their correlation in abstinent 3,4-methylenedioxymethamphetamine users (review, “This suggests that serotonin transporter (SERT) availability is not a biomarker for MDMA-induced cognitive impairment and likely also not for MDMA-induced neurotoxicity“)

- The environmental release and ecosystem risks of illicit drug during Glastonbury Festival (“MDMA mass loads were 104 times greater downstream in comparison to upstream sites … This concentration is deemed harmful to aquatic life using Risk Quotient assessment (RQ) and provides evidence of continuous release after the festival due to leaching of MDMA from the site.”)Wastewater analysis for psychoactive substances at music festivals across New South Wales, Australia in 2019-2020 (related)

- A Phenomenology of Challenging Psychedelic Experiences: From Relational Trauma to Relational Healing (thesis, “… phenomenological structure of challenging psychedelic experiences consisting of a change process that moved the participants from a sense of disconnection to a sense of connection with themselves, others, nature and the cosmos.”)
- Hard Boiled: Alcohol Use as a Risk Factor for MDMA-Induced Hyperthermia: a Systematic Review (safety, review, “It is concluded that recreational and clinical MDMA-users should refrain from concomitant drinking of alcoholic beverages to reduce the risk for adverse health incidents when using MDMA.“)
