The intensity of altered states of consciousness (ASC) induced by a psychedelic represents a key mechanism underlying the therapeutic effects of psychedelic-assisted therapy (PAT). However, growing evidence suggests that expectations may contribute significantly to therapeutic effects of PAT. The present study examined whether a psychedelic placebo could induce an ASC in a PAT- analogous...

Background: Despite significant advancements in the treatment of depression, challenges such as inadequate response rates and high placebo effects highlight the need for improved therapies and a deeper understanding of treatment expectations. Patient expectations play a crucial role in treatment outcomes but have not been systematically investigated in the context of novel interventions like...

Evidence on the neuropsychological consequences of classic psychedelics like psilocybin, LSD, and ayahuasca is conflicting, and little is known about how sporadic use of psychedelics under naturalistic conditions may affect cognitive functioning. Given the growing interest in the therapeutic potential of psychedelics and the rise in non-medical use, further exploration into their...

Classic psychedelics and MDMA have a colorful history of recreational use, and both have recently been re-evaluated as tools for the treatment of psychiatric disorders. Several studies have been carried out to assess potential long-term effects of a regular use on cognition, delivering distinct results for psychedelics and MDMA. However, to date knowledge is scarce on cognitive performance...

Serotonergic psychedelics (SP) are psychoactive substances that produce unique sets of subjective effects, such as hallucinatory experiences. This systematic review is the first to summarise which motives for SP use have been assessed in medical, psychological, sociological and ethnological research across different types of SPs and across cultural backgrounds. Findings on use motives can be...

ObjectivesBoth substance use, on the one hand, and the first signs of psychosis, on the other, commonly begin in adolescence. Adolescents with substance use disorder (SUD) frequently show recreational use of cannabis and 3,4-methylenedioxymethamphetamine (MDMA). When attenuated psychotic symptoms (APS) occur during the course of SUD, they are commonly attributed to the cannabis use, neglecting...

Background: Serotonergic psychedelics (SPs) like LSD, psilocybin, DMT, and mescaline are a heterogeneous group of substances that share agonism at 5-HT 2a receptors. Besides the ability of these substances to facilitate profoundly altered states of consciousness, persisting psychological effects have been reported after single administrations, which outlast the acute psychedelic effects. In...

ABSTRACT Background: Adolescent patients with a substance use disorder (SUD) often fulfil the criteria for a co-occurring post-traumatic stress disorder (PTSD). However, it is not clear if these dual-diagnosed adolescents present with unique levels of substance use and how their substance use relates to PTSD symptom clusters. Objective: To investigate substance use in adolescents with...

Introduction: Nitrous oxide (N2O) is a psychoactive substance with euphoric and mildly hallucinogenic effects and a variety of medical applications. Non-medical use of N2O is widespread and in recent years, there has been a significant increase across the world. To investigate potential drivers of this increase, this review summarizes the current state of research on use motives for N2O...
