Ayahuasca, a plant-based hallucinogen that serves as a spiritual medicine in South America, has improved depression in at least one placebo-controlled clinical trial. Case studies suggest that dramatic behavioral changes often follow the Ayahuasca ceremony, but most explanations of antidepressant effects focus on changes in mindfulness. This study investigated whether both mindfulness and...
Lysergic acid diethylamide (LSD) is a potent hallucinogenic substance that was extensively investigated by psychiatrists during the 1950s and 1960s. Researchers were interested in the unique effects induced by this substance, some of which resemble symptoms seen in schizophrenia. Moreover, during that period LSD was studied and used for the treatment of several mental disorders such as...
The psychedelic research renaissance is gaining traction. Preliminary clinical studies of the hallucinogenic fungi, psilocybin, with psychological support, have indicated improvements in mood, anxiety and quality of life. A seminal, open-label study demonstrated marked reductions in depression symptoms in participants with treatment-resistant depression (TRD). The associated neurobiological...
Background: There is a growing interest in the use of psychedelic substances for health related purposes, including symptom relief for disorders like anxiety, depression, and pain. Although the focus of recent clinical trials has been on high doses of these substances, anecdotal evidence suggests that low (micro) doses are also effective, and may be more suitable for certain conditions....

Recent findings have suggested that psychedelic drugs may have a role in the treatment of depressive symptoms, and a number of groups are in the process of developing protocols to study this question...
Posttraumatic stress disorder is a prevalent mental health condition with substantial impact on daily functioning that lacks sufficient treatment options. Here we evaluate six phase 2 trials in a pooled analysis to determine the study design for phase 3 trials of MDMA-assisted psychotherapy for PTSD. Six randomized, double-blind, controlled clinical trials at five study sites were conducted...
Multiple initiatives at the national and international level support natural drug discovery. Psychiatrists and patients are not well informed about natural psychotropics in general. Existing antidepressant and antipsychotic drugs were developed from atropine, a natural product. Subsequent drug developments were largely based on extension and modification of earlier molecular scaffolds. This...
AIMS AND OBJECTIVES: To explore the studies that used interventions based on the Mindfulness-Based Stress Reduction (MBSR) for decreasing psychological distress among nurses. BACKGROUND: Because of the demanding nature of their work, nurses often have significantly high levels of stress, anxiety and depression. MBSR has been reported to be an effective intervention to decrease psychological...
ABSTRACT The effects of cannabis reported by users range from experiences of euphoria and anxiolytic effects to paranoia, anxiety, and increased risk of depression. Attempts to reconcile the apparent contradictions in user response have not been conclusive. Here, we utilized selectively-bred stress-resilient socially dominant (Dom) and stress-sensitive socially submissive (Sub) mice to...
Objective: The purpose of the present study was to obtain patient information across a wide geography about medical history, drug use, symptoms, and treatments of individuals diagnosed with hallucinogen persisting perception disorder (HPPD). Methods: The study was an internet survey that yielded 26 HPPD patients from North America (81%), Europe (12%), and South America (almost 8%),...
