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%),...
Ayahuasca is a botanical hallucinogenic preparation traditionally used for ritual and therapeutic purposes by native populations of the Northwestern Amazon. In the last decades, ayahuasca use has spread to Europe, the United States, Asia, and Africa, and interest in the possible therapeutic uses of ayahuasca for treating anxiety and mood disorder and substance-use disorders has increased both...

Background: The role of hippocampus in context-dependent recall of extinction is well recognized. However, little is known about how intervention-induced changes in hippocampal networks relate to improvements in extinction learning. In this study, we hypothesized that mindfulness training creates an optimal exposure condition by heightening attention and awareness of present moment sensory...
Abstract Graduate healthcare students can experience stress that affects their ability to perform academically and clinically, decreases empathy, and affects their well-being and clinical competence. The purpose of the current study was to determine the effects of a seminar on a yoga-inspired biopsychosocial-spiritual model of self-care on perceived levels of anxiety, self-compassion,...
Background Although it has been determined that mindfulness meditations are positively related to personality constructs such as conscien-tiousness, there is no clear evidence of whether personality can influence the effectiveness of mindfulness intervention. The aim of the current research was to investigate the immediate effects of single sessions of mindfulness meditation (MM) and...

The purpose of the present study is to conduct a bibliographic review to organize scientific evidence on the...
The use of cannabis is rapidly gaining legal status across North America. Such dramatic legislative shifts have prompted an urgency in elucidating the stimulus effects of cannabis consumption. Cannabis use, though relatively safe compared to other drugs of abuse, has been associated with greater risk of mental health disorders, possibly via its primary psychoactive constituent,...
Synthetic cannabinoids are psychoactive substances designed to mimic the euphorigenic effects of the natural cannabis. Novel unregulated compounds appear once older compounds become illegal. It has been previously reported that synthetic cannabinoids are different than Δ9 -tetrahydrocannabinol (Δ9 -THC) as they have chemical structures unrelated to Δ9 -THC, different metabolism and, often,...
Background: As individuals are increasingly attending health and wellness courses outside of the conventional medical system, there is a need to obtain objective data on the effects of those programs on well-being. Methods: In total, 154 men and women (mean age 54.7 years; range 25-83) participated in 3 different holistic wellness programs based on Ayurvedic Medicine principles (Seduction of...
This study presents the impact of chaplain-provided mindfulness meditation (MM) groups on state-anxiety in adolescent inpatients on an acute psychiatric unit, an understudied topic that warrants further research given that anxiety is a demonstrated predictor of suicide attempts in adolescents and the elevated suicide risk of this population. A total of 53 adolescent patients, age 13–19,...
N, N-dimethyltryptamine (DMT) is an indole alkaloid produced by a number of plants and animals, including humans. Its psychoactive effects were first described in 1956 by Stephen Szára, but have been exploited for centuries by South American indigenous populations in the form of ayahuasca. In the present review, we assess the state of the art regarding a putative role for endogenous DMT and...
