For several years, I have been interested in the Brazilian churches that use a particular mind-altering brew as a sacrament. This brew is referred to as "ayahuasca,""yage,""hoasca," etc., depending on the part of the country in which one encounters it. I am often invited to participate in evening ceremonies by the church elders, and one visit was especially memorable.

AbstractGeometry optimization for each member of a series of 15 substituted phenethylamines with reported psychotomimetic activity was performed using MM2 and MOPAC93 (AM1) methods. This was followed by calculation of previously developed, numerically unitary structure indices, viz., the molecular transform indices FTm, FTe, and FTc, indicating general, electronic, and charge properties...

Thinking is known to be state dependent but a systematic study of how thinking in dreams differs from thinking while awake has not been done. The study consisted of analyzing the dream reports of 26 subjects who, in addition to providing dream reports also provided answers to questions about their thinking within the dream. Our hypothesis was that thinking in dreams is not monolithic but has...

Abstract: Psychoses are relatively low prevalence disorders that have a disproportionately negative impact on individuals and society. Cannabis use is one factor that can exacerbate the negative consequences associated with psychotic disorders. Relatively few studies have examined the effects or reasons for using cannabis self‐reported by individuals with psychosis. The present study is the...

Dextromethorphan is an over-the-counter dissociative agent of increasing popularity as a drug of abuse among younger adolescents. The drug produces a range of toxicities depending upon either the dose or the components of the specific formulation that was ingested. Most cases improve with supportive care alone, but severely intoxicated patients may require significant attention. Because...

The N-methyl-d-aspartate (NMDA) receptor antagonist ketamine produces episodic memory deficits. We used functional magnetic resonance imaging to characterize the effects of ketamine on frontal and hippocampal responses to memory encoding and retrieval in healthy volunteers using a double-blind, placebo-controlled, randomized, within-subjects comparison of two doses of intravenous ketamine....

We used PET (15)O and a modified version of the Stroop task to determine if 25-day abstinent heavy marijuana (MJ) users have persistent deficits in executive cognitive functioning (ECF) and brain activity. Performance on a modified version of the Stroop task and brain activity was compared between 25-day abstinent, heavy marijuana users (n = 11), and a matched comparison group (n = 11). The...

Abstract It is not possible to engage in reflection on the relationship of mind and brain without considering the evolutionary history that produced brains in the first place. Or rather, it is certainly possible, since many have written treatises in the philosophy of mind without considering evolution. A dualist might well conclude that she is not required to consider evolution since, however...

Abstract 3,4,‐Methylenedioxymethamphetamine (MDMA; ‘ecstasy’) acts at monoamine nerve terminals to alter the release and re‐uptake of dopamine and 5‐HT. The present study used microdialysis in awake rats to measure MDMA‐induced changes in extracellular GABA in the ventral tegmental area (VTA), simultaneous with measures of extracellular dopamine (DA) in the nucleus accumbens (NAC) shell....

The use of ecstasy (MDMA) has developed in the young since the eighties, particularly in festive settings. Among the severe adverse events induced by this synthetic drug, the hepatotoxicity related to MDMA and to its physiopathological mechanism warrant attention. A 21 year-old man consulted for anaemia that had persisted over the past months with abnormality in hepatic profile. The...
