How CBD Modulates THC’s Impact on the Brain

Researchers have identified how CBD interacts with cannabinoid receptors to mitigate the negative effects of THC, the psychoactive component of cannabis. Unlike THC, which fully activates the receptor and causes side effects like memory loss and addiction, CBD acts as a modulator, fine-tuning receptor activity.

Cannabis Use Reduces Brain Activity in Key Memory Regions

A study of over 1,000 young adults reveals that both recent and heavy lifetime cannabis use reduce brain activity in regions critical for working memory, including the prefrontal cortex and anterior insula. This reduced activity correlates with poorer performance on memory tasks like following instructions or solving problems.

Psychosis Risk Tied to Heavy Cannabis Use and Genetic Factors

Heavy cannabis use and genetic risk for schizophrenia independently contribute to the likelihood of developing psychosis. Researchers used two large datasets to analyze the relationship between cannabis use, schizophrenia polygenic risk scores (PRS), and psychosis.

Teens’ Views on Cannabis Tied to Perceptions of Parental Use

Teens who perceive their parents use cannabis are more likely to hold favorable views toward the drug and express intentions to try it. The impact of parental cannabis use perception varies by parent gender, with closeness to mothers and fathers influencing teens’ attitudes differently.

Cannabis Impacts Brain Plasticity via Astrocyte Receptors

Researchers discovered that cannabis affects brain development by interacting with CB1 receptors on astrocytes, not just neurons. Using a mouse model, they showed that removing these receptors impaired the brain’s ability to adapt during critical periods of plasticity, particularly in the visual cortex.

Can Cannabis Help ADHD?

Researchers are investigating how cannabis affects ADHD symptoms, focusing on its interactions with the body's endocannabinoid system. Evidence suggests cannabis influences attention, hyperactivity, and anxiety, but the findings are limited due to legal restrictions and the complexity of ADHD presentations.

Alcohol Use Predicts Escalating Cannabis Vaping Among Youth

A recent study highlights alcohol as the strongest predictor of cannabis vaping initiation and experimentation among youth and young adults, regardless of demographic factors. Conducted over three years, the research found that alcohol consumption increased the likelihood of transitioning from non-use to cannabis vaping.

Cannabis Worsens Brain Connectivity Deficits in Psychosis Risk

Young adults at risk of psychosis show reduced synaptic density, a critical brain connectivity deficit that cannabis use appears to exacerbate, according to new research. The study revealed lower synaptic density linked to social withdrawal and motivational deficits, symptoms poorly addressed by current medications.

Cannabis Use Linked to Epigenetic Changes, Cancer Risk

Research indicates that cannabis use causes cellular damage that increases the risk of highly cancerous tumors by disrupting mitochondria and damaging DNA. This genotoxicity can result in mutations, accelerated aging, and birth defects, with potential to be passed on to future generations through egg and sperm. Insights from broader mitochondrial research provide a mechanistic understanding of how cannabis affects genetic stability.

Cannabis Compound Found to Improve Sleep

Researchers have demonstrated that cannabinol (CBN), a compound found in aged cannabis, improves sleep in rats. The study revealed that CBN increased both NREM and REM sleep, leading to more total sleep time with effects comparable to zolpidem, a common sleep medication.

Metabolic Pathways Link Cannabis to Psychosis in Teens

A study investigated how cannabis use influences metabolomic patterns linked to psychotic-like experiences in adolescents. Blood samples revealed that non-cannabis users showed inflammatory metabolic changes associated with hallucinations, while cannabis users exhibited shifts in energy-related metabolites tied to brain ketogenesis. These findings suggest that cannabis use may trigger distinct molecular pathways in psychotic-like experiences.
