Cannabis

A new study suggests a compound in cannabis could protect the brain from Alzheimer’s disease. Researchers found that treating rats with cannabidiol prevented memory loss and inflammation by activating specific brain receptors.

Swapping a beer for a cannabis drink could reduce alcohol-related harms. New research indicates that consumers of infused beverages are likely to use them as substitutes, resulting in fewer weekly drinks and less bingeing.

A new study suggests that adding cannabidiol, commonly known as CBD, to products containing caffeine and delta-9-tetrahydrocannabinol (THC) can intensify the drug’s psychoactive effects and increase impairment.

A new study suggests cannabidiol may prevent sensitization to combined cocaine and caffeine. The findings link this protective effect to specific gene expression changes in the brain’s extracellular matrix.

New findings suggest cannabis microdosing protects cognition in mild Alzheimer’s cases without the side effects of recreational use.

New research shows that smoking cannabis with 7.2% THC reduced alcohol intake by nearly a third in heavy drinkers.

New research tracks how THC exposure during pregnancy disrupts fetal brain development and leads to sustained structural changes in adulthood.

New research suggests CBD shields the brain from relapse triggers by repairing molecular damage caused by opioid use.

Research involving frequent older cannabis users indicates that smoking marijuana slows executive function but produces inconsistent effects on memory, suggesting the aging brain may process the drug’s acute effects differently than younger brains.

A new study shows frequent marijuana use increased among California 11th graders following the 2018 legalization of recreational retail. However, students in cities with bans on dispensaries reported lower usage rates than those with legal shops.

In a recent laboratory experiment, cannabis use was associated with reduced alcohol consumption among heavy drinkers. This substitution effect appears to be driven by a significant decrease in the self-reported urge to drink.

Cannabidiol is often seen as a protective component of cannabis. A new study challenges this idea in a specific group of patients, revealing a surprising and counterintuitive interaction between the two substances.

How does cannabis use during pregnancy affect the developing brain? A new study in rats explored the role of a key nutrient in brain development, finding that dietary changes could influence some, but not all, of the outcomes associated with...

Scientists may have found a reason why cannabis users who also smoke tobacco report worse mental health. A new study reveals that co-use is associated with elevated levels of a specific brain enzyme involved in mood regulation.

A study of adolescent twins links occasional cannabis use with increased psychotic-like experiences. The findings suggest the relationship is shaped by individual environments rather than shared genetics or specific brain connectivity patterns.
