Psychedelic iatrogenic structural dissociation: an exploratory hypothesis on dissociative risks in psychedelic use

This paper explores potential risks of psychedelic use in people who have experienced trauma, proposing that psychedelics might reactivate unprocessed traumatic memories and cause psychological instability. The authors suggest that while psychedelics show promise for treating depression and PTSD, people with trauma histories need careful screening and support before, during, and after use. They recommend body-focused therapies and strong social support to help safely integrate traumatic material that might surface during psychedelic experiences.

Decreases in State and Trait Anxiety Post-psilocybin: A Naturalistic, Observational Study Among Retreat Attendees

This study followed 52 people who attended psilocybin retreats in the Netherlands and measured their anxiety levels before, one day after, and one week after the experience. Participants showed significant reductions in both immediate anxiety (state anxiety) and long-term anxiety tendencies (trait anxiety) that lasted up to a week. The anxiety improvements were most strongly linked to feeling a sense of ego dissolution during the experience and to lasting changes in personality traits, particularly becoming less neurotic.

Comparing Antidepressant Effects of Psilocybin-Assisted Psychotherapy in Individuals That Were Unmedicated at Initial Screening Versus Individuals Discontinuing Medications for Study Participation

This study compared how well psilocybin therapy works for people with treatment-resistant depression depending on whether they were already off antidepressants or had stopped taking them for the study. The researchers found that both groups improved similarly in depression and anxiety symptoms after receiving psilocybin with therapy support. These results suggest that stopping antidepressants before psilocybin treatment may not reduce its effectiveness, though more research is needed to fully understand the relationship between medication status and treatment outcomes.

Methodological challenges in psychedelic drug trials: Efficacy and safety of psilocybin in treatment-resistant major depression (EPIsoDE) – Rationale and study design

This research paper describes a major clinical trial testing whether psilocybin (the active compound in magic mushrooms) can treat depression that doesn’t respond to standard medications. The trial involves 144 patients receiving either psilocybin at different doses or a placebo in a carefully controlled medical setting with psychological support. The researchers developed special methods to address unique challenges in psychedelic research, such as making it difficult for patients to guess whether they received the active drug, and ensuring all patients eventually get access to the potentially helpful treatment.

Negative affective bias in depression following treatment with psilocybin or escitalopram – a secondary analysis from a randomized trial

This research compared how psilocybin mushrooms and escitalopram (a common antidepressant) affect the way depressed people perceive emotions. Both treatments helped patients become better at recognizing positive facial expressions and less likely to misinterpret neutral or positive faces as negative. Interestingly, while both treatments improved emotional processing similarly, the improvements were connected to later mood improvement in different ways for each drug, suggesting they may work through somewhat different mechanisms in the brain.

Simultaneous cannabis and psychedelic use among festival and concert attendees in Colorado: characterizing enhancement and adverse reactions using mixed methods

This study surveyed music festival and concert attendees in Colorado about their experiences using cannabis and psychedelics together. Researchers found that most people reported cannabis made their psychedelic experience better by reducing anxiety, enhancing mood, or intensifying effects. Only a small percentage experienced negative effects like increased anxiety or confusion. The study suggests cannabis may help people manage difficult psychedelic trips, though more research is needed to understand how different types and amounts of cannabis affect outcomes.

Psychedelic Psilocybin-Assisted Therapy Reduces Depressive Symptoms in Adults with Cancer and Depression

Researchers conducted a trial testing psilocybin-assisted therapy in cancer patients with depression. Participants received a single dose of psilocybin combined with therapy sessions. After eight weeks, most patients showed significant improvement in depression symptoms, with many achieving full remission. The treatment was generally safe with only mild side effects, and patients reported feeling more hopeful and better equipped to cope with their cancer diagnosis.

A systematic review to assess the use of psilocybin in the treatment of headaches

Researchers reviewed eight studies examining whether psilocybin, a naturally occurring psychedelic compound found in certain mushrooms, could treat various types of headaches and migraines. Most studies found that psilocybin provided clinically significant relief, with participants experiencing improvements in how often they got headaches, how intense they were, and how long they lasted. However, some users experienced side effects like hallucinations or temporary increases in anxiety, and the compound remains illegal in most countries, limiting current research.

Biological studies of clavine alkaloids targeting CNS receptors

This paper reviews clavine alkaloids, a class of natural compounds from ergot fungi that show promise as psychiatric medications. Unlike well-known psychedelics like LSD, clavine alkaloids may provide therapeutic benefits for anxiety and depression without strong hallucinogenic effects. The authors highlight how these compounds interact with brain receptors in ways that could make them safer and more effective medications for treating mood and neurological disorders.

Postpartum depression: A role for psychedelics?

Postpartum depression affects many new mothers and involves feelings of disconnection from themselves and their babies. This review suggests that psilocybin, the active compound in psychedelic mushrooms, might help by promoting reconnection and acceptance. The authors examine safety data suggesting psilocybin could potentially be used safely in postpartum women if appropriate precautions are taken, such as temporarily stopping breastfeeding after treatment.
