Effects of classical psychedelics on implicit and explicit emotional empathy and cognitive empathy: a meta-analysis of MET task

This study compiled data from multiple research studies to understand how classical psychedelics like LSD, psilocybin, and ayahuasca affect empathy—the ability to understand and share others’ feelings. The findings show these substances significantly increase emotional empathy, helping people feel more connected to others’ emotions. However, they don’t appear to affect cognitive empathy, which is the mental ability to understand what others are thinking. These results suggest psychedelics may have therapeutic potential for improving social connection and emotional understanding.

Naturalistic psychedelic therapy: The role of relaxation and subjective drug effects in antidepressant response

Researchers studied how LSD and psilocybin work in real-world therapy settings in Switzerland. They found that these compounds effectively reduced depression symptoms in patients who hadn’t responded to other treatments. Surprisingly, the feeling of relaxation during the session was more important for improvement than having intense mystical experiences. The therapy was generally safe, with side effects that resolved quickly.

The Role of Psychedelics in the Treatment of Substance Use Disorders: An Overview of Systematic Reviews

This research review examines how psychedelic drugs like psilocybin and ketamine might help treat addiction. Studies show these substances could help people quit alcohol, drugs, and smoking by reducing cravings and promoting long-term abstinence. While results are promising, scientists caution that more rigorous research is needed before these treatments can be recommended for regular medical use, and they acknowledge real risks associated with these powerful drugs.

The therapeutic potential of microdosing psychedelics in depression

This review examines whether taking very small doses of psychedelic drugs like LSD and psilocybin might help treat depression. While users report benefits and some studies show subtle positive effects on mood and thinking, scientists have not yet confirmed whether microdosing actually works as a depression treatment. More research with depressed patients is needed to understand if this approach is truly helpful and safe for regular use.

Addressing blinding in classic psychedelic studies with innovative active placebos

This research paper discusses how scientists can better test whether psychedelic drugs actually work by improving the way they conduct clinical trials. A major problem is that psychedelic drugs produce obvious effects that make it easy for patients and researchers to figure out who received the real drug versus a fake one. The authors recommend using different types of drugs as placebos that produce similar effects without being therapeutic themselves, such as certain existing medications. By using these better-designed placebos along with other strategies, future research can more definitively prove whether psychedelics truly help treat depression, chronic pain, and other conditions.

Psychotomimetic compensation versus sensitization

This paper proposes a new way to understand why drugs that can cause psychosis-like effects (such as psilocybin, LSD, and ketamine) can also help treat depression and anxiety. The authors suggest that these drugs trigger compensatory responses in the brain that temporarily help us cope with stress, similar to how a runner’s high feels good during exercise. However, if someone uses these drugs repeatedly or experiences chronic stress, they may become sensitized and more vulnerable to developing actual psychotic symptoms over time.

Adults who microdose psychedelics report health related motivations and lower levels of anxiety and depression compared to non-microdosers

This large international study of over 8,700 people found that adults who microdose psychedelics report taking small doses for health and wellness reasons. Among people with anxiety or depression, microdosers showed lower symptom levels than non-microdosers. Most microdosers used psilocybin and combined it with other substances like Lion’s Mane mushrooms or niacin, practices they refer to as stacking.

The Afterglow Inventory (AGI): Validation of a new instrument for measuring subacute effects of classic serotonergic psychedelics

Researchers created a new questionnaire called the Afterglow Inventory to measure the positive effects people experience in the days and weeks after using psychedelics like psilocybin and LSD. These ‘afterglow’ effects include improved mood, feelings of spiritual connection, increased creativity, and better relationships. The study with over 1,300 participants showed the questionnaire works well at measuring these effects, which could help researchers better understand how psychedelics might help treat depression and other conditions.

Knowledge, perceptions, and use of psychedelics for mental health among autistic adults: An online survey

This survey studied how autistic adults feel about using psychedelics like psilocybin mushrooms for mental health. Nearly 70% of participants had tried psychedelics before and most found them helpful for anxiety and depression. Many participants were interested in trying them or participating in research, though legal and practical barriers stood in the way. The study suggests that psychedelics could be a promising treatment option for autistic people with mental health challenges.

Direct comparison of the acute effects of lysergic acid diethylamide and psilocybin in a double-blind placebo-controlled study in healthy subjects

This study directly compared two popular psychedelic drugs, LSD and psilocybin (magic mushrooms), in 28 healthy volunteers. Researchers found that these substances produce very similar mental effects when given at equivalent doses, with the main difference being that LSD lasts longer. The study establishes that about 20 milligrams of psilocybin is roughly equivalent to 100 micrograms of LSD. These findings could help guide dosing for future psychiatric treatments using these psychedelics.
