Background and Aims The ongoing opioid epidemic remains a major public health crisis in the United States, with over 100,000 opioid-related deaths annually. Mental health disorders are strongly associated with opioid use disorder (OUD), compounding risks of misuse and overdose. Emerging evidence indicates that psychedelics may be associated with reduced risk...
IntroductionBipolar disorder (BD) is a severe and persistent mental disorder characterized by recurrent mood episodes, with BD depression accounting for most of the illness burden. Although the mainstay treatment of BD consists of pharmacotherapy with mood stabilizers and atypical antipsychotics, a large proportion of patients with BD depression do not respo...
Psychedelic-assisted therapy (PAT) frequently utilises a “cotherapy” model, in which two therapists jointly support participants or patients through preparation, dosing, and integration sessions. While common in clinical trials, the experience of cotherapy from the participant perspective remains underexplored. This qualitative study examined experiences of ...
Introduction: Treatment-Resistant Depression (TRD) affects approximately 30-50% of patients with Major Depressive Disorder (MDD) who fail to respond to at least two adequate antidepressant trials. This condition presents substantial clinical and functional challenges, and no universally accepted treatment algorithm currently exists. Emerging therapeutic stra...
Background: Psychedelics are gaining renewed scientific interest as a treatment for mental health conditions such as major depression, post-traumatic stress disorder (PTSD), anxiety, and addiction. Numerous clinical trials and meta-analyses suggest these substances may produce significant therapeutic effects. However, there is currently no high-level synthes...
Classic psychedelic drugs, including psilocybin, lysergic acid diethylamide, and ayahuasca/N,N-dimethyltryptamine, are increasingly being studied as therapeutics for myriad health conditions; however, predicting individual responses is notoriously difficult. An arguably underappreciated variable potentially moderating responses to psychedelics is age. Older ...
Introduction In recent years, psychiatry has witnessed a renaissance in the investigation of psychedelic compounds, a broad class of psychoactive substances that induce altered states of consciousness, often characterized by changes in perception, mood, and cognition, which were largely shelved following regulatory crackdowns in the 1970s. The renewed intere...
Dementia is a progressive neurodegenerative disease which is characterised by cognitive decline, memory loss, and behavioural changes. Patients suffering from dementia often experience emotional distress, sadness and depression which also impacts the wellbeing of their caregivers. Recent research has explored the potential of psychedelics, such as psilocybin...
Serotonergic psychedelics, including the recreationally used psilocybin and LSD, have become promising therapeutic agents for the treatment of treatment-resistant depression. While it is generally agreed that they exhibit their antidepressant effects by inducing rapid and sustained neuroplasticity, the molecular mechanisms responsible are widely debated. In ...
The stresses of the Coronavirus Disease of 2019 (COVID-19) pandemic highlighted the burden of psychiatric disorders within the pediatric population, revealing a pre-existing need for rapid-onset therapies that have since driven efforts to expand effective therapeutic interventions. In this narrative review, we utilized the Preferred Reporting Items for Syste...
The resurgence of psychedelic-assisted psychotherapy marks a pivotal evolution in mental health treatment, challenging traditional paradigms by integrating compounds such as psilocybin, LSD, MDMA, and ketamine into clinical practice. Historically marginalized due to regulatory and societal concerns, these agents are now gaining recognition for their unique n...
Background and HypothesisVisual hallucinations (VH) are a core symptom of both Lewy body diseases (LBDs; e.g., Parkinson’s disease and dementia with Lewy bodies) and serotonergic psychedelics (SPs; e.g., psilocybin and mescaline). While these classes of VH differ in etiology, shared pathways are suggested by overlapping phenomenology and neural mechanisms. T...

BackgroundClassic serotonergic psychedelics are 5-HT2A partial agonists that induce non-ordinary states of consciousness. Many have demonstrated anti-addictive properties; however, their impact on smoking behaviors remains under-researched. This review provides a synthesis of the therapeutic potential of these compounds in promoting smoking cessation and red...
Psychedelics have been studied since the 1950s as a potential treatment for alcohol use disorder (AUD), with over a dozen clinical trials of lysergic acid diethylamide (LSD), and several contemporary trials of psilocybin and ayahuasca for this indication. Herein, we characterize foundational studies from the 1950s to the present, with emphasis on key design ...
Background: Individuals with bipolar II disorder (BD-II) and depression face limited treatment options and are often excluded from psilocybin therapy trials due to theoretical concerns of precipitating mania or psychosis. Although psilocybin has demonstrated antidepressant effects when combined with psychotherapy, adverse event reporting is inconsistent, and...
Psychoactive substances are compounds that can influence perception, consciousness, cognition, and emotions. The psychoactive substances caffeine, nicotine, cannabis, and psilocybin all originate from natural sources and can be used without complex processing or synthesis. Their natural availability has contributed to a long-standing history of human use and...
IntroductionNatural hallucinogens derived from fungi and animals have been used for centuries in shamanic, ritualistic, and medicinal practices across diverse cultures. These compounds exhibit a widerange of structures and mechanisms of action, affecting various neurotransmitter systems pathways. Fungal hallucinogens, primarily indole alkaloids like psilocyb...
Trauma-related disorders and substance use are disproportionately underdiagnosed and undertreated in individuals with High-Functioning Autism (Level 1 Autism Spectrum Disorder), particularly those in underserved or marginalized communities. Emerging evidence suggests that psychedelic-assisted therapies-including psilocybin, MDMA, and ketamine-offer promising...
