While the adoption of psilocybin-assisted therapy for existential distress offers promising support for patients with life-threatening illnesses, implementing this intervention into palliative care settings presents significant real-world challenges. To examine palliative care stakeholders' knowledge and attitudes regarding psilocybin-assisted therapy, and i...
This brief review highlights some of the structure-activity relationships of classic serotonergic psychedelics. In particular, we discuss structural features of three chemotypes: phenethylamines, ergolines and certain tryptamines, which possess psychedelic activity in humans. Where they are known, we point out the underlying molecular mechanisms utilized by ...
Psychedelic drugs are under active consideration for clinical use and have generated significant interest for their potential as anti-nociceptive treatments for chronic pain, and for addressing conditions like depression, frequently co-morbid with pain. This review primarily explores the utility of preclinical animal models in investigating the potential of ...
The past decade has seen a huge increase in clinical research with psychedelic drugs and 3,4-methylenedioxymethamphetamine (MDMA), which have revealed great potential for treating mental health conditions. Given this progress in research, as well as the current unmet clinical need of millions of patients, in 2023, the Australian Therapeutic Goods Administrat...
Psychedelic drugs such as LSD and psilocin were once relegated to the fringes of medical research because of their association with counterculture movements and a perceived concern about harm through recreational use, and their consequent legal prohibition in the early 1970s. However, these drugs are now experiencing a renaissance in the field of psychiatry ...
Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N-dimethyltryptamine, ayahuasca; non-hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g. ibogaine, ketamine and esketamine; and other atypicals e.g. dextrom...
Serotonergic psychedelic drugs are under investigation as therapies for various psychiatric disorders, including major depression. Although serotonergic psychedelic drugs are 5-HT receptor agonists, some such agonists are not psychedelic, potentially due to differences in 5-HT receptor ligand bias or signalling efficacy. Here, we investigated 5-HT receptor s...
Psychedelic drugs that activate 5-HT receptors have been long used for cultural, medicinal and recreational purposes. Interest in psychedelics for treating psychiatric disorders has resurged recently and is well documented; less well recognised are their anti-inflammatory properties. Growing evidence now demonstrates that psychedelics modulate immune respons...
Psychedelics have garnered great attention in recent years as treatments for major depressive disorder (MDD) and treatment-resistant depression because of their ability to alter consciousness and afflicted cognitive processes with lasting effects. We aimed to characterise how psychedelics are currently being investigated to treat substance use disorders (SUD...
Fragile X Syndrome (FXS) is the most common inherited intellectual disability and a leading monogenic cause of autism spectrum disorder (ASD). As a synaptic disorder, FXS involves the loss of Fragile X messenger ribonucleoprotein 1 (FMRP), leading to abnormal dendrite development and immature dendritic spines. Serotonergic signaling, essential for neuronal d...
Recreational drug poisonings pose a growing public health concern. European-level data remain limited, although poison centres are well placed to monitor related health incidents. This study analysed temporal trends in recreational drug poisonings reported to six European poison centres. Aggregated retrospective data were collected over four years (2021-2024...
Wood-lover paralysis is a rare complication of mushroom ingestion. The clinical spectrum is poorly characterized and published cases remain limited. We describe three patients who developed acute muscle weakness following ingestion of mushrooms in Victoria, Australia. Written informed consent was obtained from these patients for publication of this case seri...
Borderline personality disorder (BPD) is a serious mental illness with high rates of morbidity and stigma; however, successful remission is frequently limited by a paucity of accessible treatment options. In an era of growing interest in psychedelics as novel psychiatric treatment modalities, patients with BPD are often excluded from research due to perceive...
Based on its in vitro profile and preliminary evidence, 4-bromo-2,5-dimethoxyphenethylamine (2C-B) may have psychoactive properties that are similar to 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin, which are investigated for the treatment of posttraumatic stress disorder and depressive disorders. We compared acute effects of 2C-B (10, 20, and 30 m...
Treatment-resistant depression is a condition with significant morbidity, despite the current standard of treatment, including traditional pharmacotherapy, psychotherapy, augmentation strategies and electroconvulsive therapy. While novel therapies have emerged, such as ketamine/esketamine, transcranial magnetic stimulation and psilocybin-assisted therapy, th...
Natural hallucinogenic compounds have arisen independently across plants, fungi, and animals, evolving into a diverse chemical arsenal that includes phenethylamines, indolealkylamines, and terpenoid scaffolds. Beyond clinical and cultural frameworks, their ecological origins and evolutionary trajectories may help explain why such potent modulators of percept...
Fungal natural products, also called secondary metabolites (SMs), continue to inspire chemists and drug development. Around 30,000 fungal SMs are known, mainly from filamentous fungi of the phylum Ascomycota. Only 5% of all fungal species are described today, and even fewer have been cultured or chemically screened, which makes fungi an untapped reservoir fo...
In the past decade, interest in studying psychedelic compounds as potential therapeutic agents has resurged. These studies carefully exclude individuals at risk for developing psychotic symptoms in response to psychedelic use. Given the potential for psychedelics to be established as treatments in psychiatry, it is important to more robustly understand their...
Previous studies of pediatric recreational drug exposures have often been limited in scope. Given the rapidly changing recreational drug supply and the related unintentional ingestion of these drugs by young children, a comprehensive study that includes recent data about these exposures is needed. The objective of this study is to investigate the characteris...
Recreational drugs affect the cardiovascular system through distinct mechanisms; however, data regarding their cardiovascular impact in the emergency department setting is limited. This study aimed to assess the incidence of cardiovascular effects following recreational drug use in presentations to the emergency department, identify the main drug groups invo...
