Summary
Cannabis use impacts lipid pathways, reducing niacin skin flushing in schizophrenia patients and controls. This suggests a gene x environment interaction affecting schizophrenia risk and progression.
Area of Science:
- Neuroscience
- Psychiatry
- Genetics
Background:
- Cannabinoids may influence schizophrenia onset, severity, and outcomes.
- Gene x environment interactions, including cannabis use, are implicated in schizophrenia's pathomechanism.
Purpose of the Study:
- To investigate the relationship between delta-9-tetrahydrocannabinol intake and niacin sensitivity in schizophrenia patients and healthy controls.
- To explore the impact of cannabis consumption on lipid-arachidonic acid pathways.
Main Methods:
- Cross-sectional study design.
- Assessed niacin skin flushing response to methylnicotinate using optical reflection spectroscopy.
- Compared cannabis-consuming and non-consuming schizophrenia patients and healthy controls.
Main Results:
- Cannabis consumption significantly decreased skin flushing in healthy controls.
- Schizophrenia patients exhibited decreased flush response compared to controls, irrespective of cannabis use.
- An inverse association was found between skin flushing and Symptom Check List 90-R scores.
Conclusions:
- Long-term cannabis use affects lipid-arachidonic acid pathways.
- Cannabis use may exacerbate pre-existing lipid metabolism vulnerabilities in schizophrenia.
- Findings support a gene x environment interaction model for schizophrenia.

01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...

01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its effects by...
01:29Biological Causes of Schizophrenia
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin studies.

01:27Hallucinogens and Psychedelics
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
