The illicit drug 3,4-methylenedioxymethamphetamine (MDMA) has recently shown promising efficacy as an adjunct to psychotherapy for posttraumatic stress disorder (PTSD), although the underlying mechanisms are poorly defined. In this review, we contextualize the emergence of MDMA-assisted psychotherapy (MDMA-AT) within 20th century psychiatry and trace its journey from assisting with military...
Cannabis is often consumed in polysubstance contexts, yet research comparing its isolated use to polydrug use is limited. Such comparisons are essential for understanding substance-specific versus interactive effects on brain activity. This study investigates how cannabis-only and polydrug use relate to alterations in resting-state EEG functional connectivity, using the Directed Transfer...
In a suburb of Vancouver, Canada, a nondescript three-story building sits alongside a strip of parking lots. From the outside, it looks like an ordinary commercial office space. But inside is something more extraordinary: rows of shelves stacked with plastic tubs full of magic mushrooms—mushrooms that contain the hallucinogenic chemical psilocybin. In a year, enough psychedelic mushrooms can be...
Psychedelics are mind-altering substances that have shown promising effects in the treatment of neuropsychiatric disorders owing to their antidepressant, anxiolytic and antiaddictive effects. However, data on their developmental toxicity is scarce, which might hinder its therapeutic suitability, and preclinical data on their behavioral effects is mainly restricted to rodents. In this context,...
Novel psychoactive substances (NPS) are increasingly used by young individuals for their psychoactive effects and have been frequently associated with the emergence of psychotic symptoms and schizophrenia spectrum disorders. However, it remains unclear whether NPS use directly increases the risk of psychosis onset or whether individuals with a predisposition to psychosis are more likely to...

Humans have long used various substances to enhance sexual pleasure and performance, often at the expense of their overall health. This review investigates the sexual-related effects of recreational drugs, including amphetamines, 3,4-methylenedioxymethamphetamine (MDMA), mephedrone, gamma-hydroxybutyrate (GHB), and ketamine. By examining anecdotal evidence, self-reports, and limited scientific...
Background: Posttraumatic stress disorder (PTSD) affects approximately 5-7% of the population, with conventional treatments often proving inadequate for some patients. Recent studies suggest that methylenedioxymethamphetamine (MDMA) combined with psychotherapy may offer a novel therapeutic approach. This systematic review evaluates the efficacy and safety of MDMA-assisted psychotherapy for the...
Psychedelic research is progressing at breakneck speed and is creating new challenges for drug developers, regulatory authorities, and legislators. Most “classic” psychedelics undergoing clinical investigation are C-I controlled drugs with perceived high potential for abuse and no medical use. These and next-generation psychedelic drug-candidates require scientific and clinical assessment of...
