Cannabidiol boosts social learning by enhancing brain acetylcholine signaling, study finds
Cannabidiol appears to improve social memory in mice, according to new research in Psychopharmacology. The study shows that CBD enhances the ability to remember food-related information from peers by increasing acetylcholine activity in the basal forebrain.
Researchers uncover causal evidence that cannabis legalization reduces problematic consumption
Researchers in Switzerland have completed the first randomized trial comparing legal and illegal cannabis use. The study suggests that public health-oriented cannabis access may help reduce misuse, particularly among people with more complex patterns of drug use.
Daily use of cannabis is strongly associated with chronic inflammation, study finds

Surprising link between cannabis use and cognitive decline uncovered after analyzing decades of data
A study tracking men for 44 years found past cannabis use did not accelerate cognitive decline. Users actually experienced a slightly smaller decline than non-users.
How cannabis influences brain plasticity: Scientists uncover crucial role of astrocytes
New research reveals astrocytes, not just neurons, are crucial for cannabinoid receptor-mediated brain plasticity during development.
Legal cannabis linked to drop in anxiety medication prescriptions
Could legal marijuana be changing how we treat anxiety? A new study in JAMA Network Open reveals that in states with legal cannabis, fewer patients are filling prescriptions for anti-anxiety medications like benzodiazepines.
