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...
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...
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...

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...
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...
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...
Little comparative data on substance use (SU) between sexual minority youth (SMY) and heterosexual youth (HET) is available. This study compares the prevalence of SU in an urban cohort between SMY and HET and evaluates demographic and psychosocial predictors of SU. Data came from a prospective-longitudinal cohort study in an urban setting (N = 1297). SU and psychosocial variables such as...
Background: In the wake of positive clinical trial outcomes of psychedelic-assisted psychotherapy for the treatment of various psychiatric disorders, there has been an influx of financial investment into psychedelic drug development from the pharmaceutical and biotech sectors. Psychedelics are now a multibillion dollar industry, with hundreds of companies that are seeking to commercialize...
Much recent attention has been directed toward the spatial organization of the cell nucleus and the manner in which three-dimensional topologically associated domains and transcription factories are epigenetically coordinated to precisely bring enhancers into close proximity with promoters to control gene expression. Twenty lines of evidence robustly implicate cannabinoid exposure with...

Ayahuasca is a tea used in original indigenous rituals with the aim of expanding the mind and consciousness. Some studies have pointed to Ayahuasca as a potent antidepressant with reduced side effects when compared to other conventional synthetic allopathic treatments. Over the years, tea has come to be known by both the popular community and the scientific community. The species used are...
