CBD May Reduce Intestinal and Liver Damage in Acute Mesenteric Ischemia, Study Finds
Administering cannabidiol (CBD) shortly before blood flow was restored to the intestines reduced tissue damage and helped protect the liver in a rat model of acute mesenteric ischemia, according to a study by researchers from Complutense University of Madrid, the University of the Basque Country and Hospital de Galdakao. For the study, researchers examined whether …
Study Finds Teen Marijuana Use Fell More Than 60% From 2013 to 2025 Despite Legalization
Marijuana use among Minnesota adolescents fell substantially between 2013 and 2025, declining across every demographic group examined even as the state adopted increasingly permissive marijuana laws during that period, according to a new study. Published by Social Science & Medicine, the study was conducted by researchers from the University of Minnesota, University of Connecticut and …
Study Details How Temperature and Catalyst Determine CBD’s Conversion Into Different Forms of THC
A new study provides a more detailed explanation of how temperature and catalyst type influence whether acid-catalyzed conversion of cannabidiol (CBD) produces primarily delta-9 THC, delta-8 THC or iso-delta-8 THC. Published in the journal Organic & Biomolecular Chemistry, the study combined laboratory experiments with computational modeling to examine the acid-catalyzed conversion of CBD into THC-type …
Study Reports First Successful Callus Induction From Cannabis Anthers
Researchers at the University of Connecticut have reported the first successful induction of callus tissue from cannabis anthers, a development that could eventually support faster and more precise cannabis breeding. The study, published in HortScience, was conducted by Michelle M. McDonald and Jessica D. Lubell-Brand of the university’s Department of Plant Science and Landscape Architecture. …
Study Finds 85% of Bulgarian Chronic Pain Patients Open to Using CBD if Recommended by a Healthcare Professional
A new study has found substantial interest in cannabidiol (CBD) among patients in Bulgaria with chronic pain and neurodegenerative diseases, with more than 85% saying they would consider using CBD if it were recommended by a healthcare professional. Published in the journal Pharmacia, the study was conducted by researchers from the Medical University of Plovdiv …
Review Finds Nanoencapsulation Could Improve Cannabinoid-Based Pain Treatments
Encapsulating cannabinoids in lipid nanoparticles may improve their stability, absorption and pain-relieving effects, according to a new review published in the journal Pharmaceutics. Researchers from the Federal University of Rio Grande do Norte and the Federal University of Uberlândia in Brazil reviewed the available evidence on nanoencapsulated cannabinoids, particularly cannabidiol (CBD), for managing acute, chronic …
THCV and CBD Reduce Voluntary Alcohol Consumption in Long-Term Animal Study
Tetrahydrocannabivarin (THCV) and cannabidiol (CBD) both reduced voluntary alcohol consumption among male rats with a long history of drinking, according to a new long-term animal study from Vilnius University. The research examined whether the two cannabis compounds affect different components of alcohol consumption, including the motivation to begin drinking and the reinforcing effects that encourage …
CBD Reduces Brain Inflammation, Partially Restores Immune-Cell Function in Study of Gulf War Illness
Chronic cannabidiol (CBD) treatment reduced excessive brain inflammation and partially restored impaired immune-cell function in a model of Gulf War Illness, according to a new study from researchers at the University of California. The study examined how Gulf War Illness affects microglia, the brain’s resident immune cells, as animals age. Gulf War Illness is a …
CBD and Anti-Inflammatory Drug Combination Shows Potential Against Aggressive Brain Tumors in Preliminary Study
A liposomal formulation combining cannabidiol (CBD) with the anti-inflammatory drug celecoxib may help slow the progression of high-grade glioma, according to a new study published in the International Journal of Molecular Sciences. Researchers from Poznan University of Medical Sciences in Poland examined formulations containing CBD, celecoxib or a combination of the two. The treatments were …
