Psychedelics: Safety and Efficacy

mycolabadmin

This paper reviews scientific research on psychedelic drugs like LSD and psilocybin that are being studied for treating depression and PTSD. While some research claims these drugs are beneficial, many studies have serious flaws including hiding negative side effects and being influenced by money from pharmaceutical companies. The author concludes that we need much better research before these drugs can be safely approved for medical use.

Biological markers of treatment response to serotonergic psychedelic therapies: a systematic review

mycolabadmin

This review examines how scientists can predict which patients will benefit most from psychedelic-assisted therapy for depression by measuring biological markers in the brain and blood. Researchers found that certain brain changes and protein levels—particularly involving the amygdala, specific brain regions, and inflammation markers—appear linked to treatment success. While the current studies are small, they suggest that measuring these biological markers could eventually help doctors personalize psychedelic treatments for depression.

Norpsilocin: freebase and fumarate salt

mycolabadmin

Researchers determined the crystal structures of norpsilocin, a naturally occurring compound found in magic mushrooms that is chemically similar to psilocin. This work is important because norpsilocin appears to be as potent as psilocin at serotonin receptors and may contribute to the therapeutic effects of magic mushroom extracts. By obtaining pure crystalline forms and understanding the compound’s structure, scientists can better study its properties and potential medical applications for treating conditions like depression and anxiety.

Psychedelics and the Serotonin Hypothesis of Eating Disorders

mycolabadmin

This review explores how psychedelic drugs like psilocybin (found in certain mushrooms) might help treat eating disorders by promoting flexible thinking and breaking rigid eating patterns. The authors summarize evidence from animal studies and early clinical trials showing that psychedelics work differently than traditional antidepressants by triggering brain changes that help people adopt new, healthier behaviors. While results are promising, more research is needed to determine the best doses, patient populations, and long-term safety.

Changes in synaptic markers after administration of ketamine or psychedelics: a systematic scoping review

mycolabadmin

This review examines how ketamine and psychedelics affect connections between brain cells. Under stressful conditions, ketamine and psychedelics appear to strengthen these connections in brain areas important for mood and learning. However, the effects are mixed under normal conditions and vary based on dose, sex, and which specific markers are measured. The findings suggest these substances may help restore brain function damaged by stress or substance use.

Transient Elevation of Plasma Glucocorticoids Supports Psilocybin-Induced Anxiolysis in Mice

mycolabadmin

This study examined how psilocybin works to reduce anxiety in mice by investigating the role of stress hormones, particularly corticosterone. Researchers found that psilocybin causes a temporary spike in corticosterone levels that is essential for its anxiety-reducing effects hours after administration. Interestingly, other interventions that increase corticosterone levels also produced similar anxiety-reducing effects, suggesting the stress hormone response itself drives the therapeutic benefit rather than psilocybin’s psychedelic properties alone. These findings suggest that measuring cortisol levels in human patients receiving psilocybin therapy could help explain and optimize therapeutic outcomes.

Efficacy of psilocybin for treating symptoms of depression: systematic review and meta-analysis

mycolabadmin

This comprehensive analysis of clinical trials found that psilocybin, a compound found in certain mushrooms, shows promise as a treatment for depression compared to placebo. The treatment was particularly effective for patients with depression related to serious illness, those using self-reported symptom assessments, older adults, and those with prior experience with psychedelics. While side effects were minimal and temporary, researchers emphasize that more research is needed to fully understand how expectancy and individual factors influence treatment outcomes.

How to account for hallucinations in the interpretation of the antidepressant effects of psychedelics: a translational framework

mycolabadmin

Psychedelic drugs like LSD and psilocybin show promise in treating depression with effects lasting months after single doses. However, scientists debate whether the hallucinations and mystical experiences these drugs produce are necessary for their healing effects. This review proposes a framework to test whether lower doses without hallucinations might still provide antidepressant benefits, similar to how anesthesia-administered ketamine works without the patient’s awareness.

Synthesis and bioactivity of psilocybin analogues containing a stable carbon–phosphorus bond

mycolabadmin

Researchers created new chemical versions of psilocybin (the active compound in magic mushrooms) that cannot be broken down by the body’s natural enzymes in the same way. They tested these new compounds to see if they could help with depression and anxiety by targeting specific brain receptors. The best compound worked well on the intended brain receptors but importantly showed less activity on a heart-related receptor, potentially making it safer than natural psilocybin.

Extensive Collection of Psychotropic Mushrooms with Determination of Their Tryptamine Alkaloids

mycolabadmin

Scientists analyzed 226 mushroom samples from about 30 psychotropic species to measure their psilocybin and related compound content. They found that the amounts of these compounds vary greatly, even within the same species, making it difficult to predict how strong a mushroom will be. The research shows that Psilocybe species generally contain the most psychoactive compounds, with some varieties containing over 15 times more psilocybin than others, highlighting safety concerns for users.
