Risk for Ecstasy Use Disorder and Other Substance Use Among International Users of Recreational Ecstasy/Molly/MDMA.

Journal of Psychoactive Drugs 2024 Nancy A Haug, Richa Wadekar, Rachel Barry et al.

Ecstasy/Molly/MDMA is a widely used substance often taken in combination with other drugs in different contexts. The current study assessed ecstasy use patterns, concurrent substance use and the context of ecstasy use among an international sample of adults (N = 1,732). Participants were 87% white, 81% male, 42% college educated, 72% employed, with a mean age of 25.7 (SD = 8.3). Using the...

Psychedelic substitution: altered substance use patterns following psychedelic use in a global survey.

Frontiers in Psychiatry 2024 Nicolas G. Glynos, Jacob S. Aday, Daniel J. Kruger et al. 15 citations

Recent research suggests that psychedelics may have potential for the treatment of various substance use disorders. However, most studies to date have been limited by small sample sizes and neglecting to include non-North American and European populations. We conducted a global, cross-sectional online survey of adults (n = 5,268, 47.2% women) self-reporting past or current psychedelic use and...

Depersonalization-derealization Disorder in Men

Health of Man December 28, 2023 Oksana Kobzar, Galyna Pyliagina

The objective: to analyze the features of the course of depersonalization-derealization disorder (DDD) in men on the example of a clinical case. Materials and methods. The pilot study included 51 individuals, namely: 8 (15.7%) men and 43 (84.3%) women, with average age 21 years (SD=3.66) and 23.86 years (SD=6.88), respectively. Study participants had criteria for DDD according to the...

Development of the Protective Strategies for Psychedelics Scale: A novel inventory to assess safety strategies in the context of psychedelics

Journal of Psychopharmacology December 4, 2023 Maha N. Mian, Brianna R. Altman, Fiona Low et al. 8 citations

Background: Individuals who use psychedelics take efforts to mitigate unintended consequences. Despite the demonstrated utility of analogous protective behavioral strategies (PBS) assessments for other substances, no standardized scale exists to capture these protective strategies for psychedelic use. Objective: The present study addresses a notable gap concerning the assessment of psychedelic...

Effects of the Acute and Chronic Administration of Cannabidiol on Cognition in Humans and Animals: A Systematic Review.

Cannabis and Cannabinoid Research December 2023 Ana Julia de Lima Bomfim, Stefany Mirrelle Fávero Zuze, Daiene de Morais Fabrício et al.

Introduction: The effects of cannabidiol (CBD) on cognition has been investigated in recent years to determine the therapeutic potential of this cannabinoid for a broad gamut of medical conditions, including neuropsychiatric disorders. The aim of the present study was to perform a systematic review of studies that analyzed the effects of the acute and chronic administration of CBD on cognition...

Public Interest in Psilocybin and Psychedelic Therapy in the Context of the COVID-19 Pandemic: Google Trends Analysis

JMIR Formative Research November 28, 2023 George Danias, Jacob Appel 13 citations

Background Psychedelic substances have demonstrated promise in the treatment of depression, anxiety, and substance use disorders. Significant media coverage has been dedicated to psychedelic medicine, but it is unclear whether the public associates psilocybin with its potential therapeutic benefits. The COVID-19 pandemic led to an increase in depression, anxiety, and substance abuse in the...

A case of incubus phenomenon

European Psychiatry November 17, 2023 L. Tjokrodipo, A. Sneep, P. Michielsen

Introduction The incubus phenomenon is a paroxysmal sleep-related disorder in which patients experience sleep paralysis and compound hallucinations. The symptoms of this phenomenon contain: sensed presence, fear, visual and auditory hallucinations, unusual body experiences such as out-of-body experience and feelings of floating/paralysis, experiencing a pressure on the thorax, difficulties...

Chronic psychosis associated with new hallucinogenic drug 25I-NBOMe

European Psychiatry October 23, 2023 O. Martin-Santiago, G. Guerra-Valera, C. Alario-Ruiz et al.

Introduction The presence of perceptual disturbances and psychotic symptoms associated with substance abuse are widely known. While the abuse of substances is becoming more widespread, there is a general perception that their use entails fewer risks. 25I-NBOMe is a recently introduced hallucinogenic drug producing visual hallucinations and euphoria. Although people consume it like LSD, its...

Subtle Structural Modification of a Synthetic Cannabinoid Receptor Agonist Drastically Increases its Efficacy at the CB1 Receptor

ACS Chemical Neuroscience October 17, 2023 Hideaki Yano, Rezvan Chitsazi, Christopher Lucaj et al. 12 citations

The emergence of synthetic cannabinoid receptor agonists (SCRAs) as illicit psychoactive substances has posed considerable public health risks, including fatalities. Many SCRAs exhibit much higher efficacy and potency compared with the phytocannabinoid Δ 9 -tetrahydrocannabinol (THC) at the cannabinoid receptor 1 (CB1R), leading to dramatic differences in signaling levels that can be toxic. In...

PPARα and PPARγ are expressed in midbrain dopamine neurons and modulate dopamine- and cannabinoid-mediated behavior in mice.

Molecular Psychiatry October 2023 Briana J. Hempel, Madeline Crissman, Sruti Pari et al.

Peroxisome proliferator-activated receptors (PPARs) are a family of nuclear receptors that regulate gene expression. Δ9-tetrahydrocannabinol (Δ9-THC) is a PPARγ agonist and some endocannabinoids are natural activators of PPARα and PPARγ. However, little is known regarding their cellular distributions in the brain and functional roles in cannabinoid action. Here, we first used RNAscope in situ...
