Study: Psilocybin Extends Lifespan in Aged Mice and Human Cells, Suggesting Anti-Aging Potential
A new study published in npj Aging finds that psilocybin, the psychoactive compound in psychedelic mushrooms, significantly extends lifespan in both aged mice and human cells—marking the first experimental evidence that the substance may have geroprotective properties. Researchers from Baylor College of Medicine and Emory University tested the effects of psilocin—the active metabolite of psilocybin—on …
Study: CBD Inhibits Osteosarcoma by Targeting Tumor-Driving Inflammation
A new study published in Phytomedicine finds that cannabidiol (CBD) can significantly inhibit the growth and spread of osteosarcoma, a highly aggressive bone cancer, by targeting a key inflammatory pathway. “Osteosarcoma remains a therapeutic challenge due to its aggressive behavior and high metastatic potential, necessitating exploration of novel treatment modalities”, states the study’s abstract. “Cannabidiol …
Study: Cannabidivarin (CBDV) May Help Improve Motor Coordination and Cognitive Function in Rhett Syndrome Patients
Researchers from Universidade de Lisboa and the Gulbenkian Institute of Molecular Medicine have found that chronic administration of cannabidivarin (CBDV), a non-intoxicating cannabinoid, may help alleviate some symptoms of Rett Syndrome in a female mouse model of the disorder. Rett Syndrome is a rare neurodevelopmental condition caused primarily by mutations in the MECP2 gene, which …
Study: Clinical Trial Finds CBD/CBDA Safe for Dogs Undergoing Chemotherapy
A new randomized, placebo-controlled clinical trial has found that short-term supplementation with CBD/CBDA-rich hemp oil appears safe and well-tolerated in dogs receiving chemotherapy for lymphoma. The study, conducted by researchers from Cornell University College of Veterinary Medicine, the University of California, and the University of Florida, was published in the Journal of Veterinary Internal Medicine. …
Study: THC-Dominant Cannabis Use Linked to Long-Term Relief From Anxiety and Depression
A new study published by the Journal of Affective Disorders found that adults with clinically significant anxiety and depression experienced substantial and sustained symptom relief after initiating medicinal cannabis, particularly THC-dominant products. Conducted by researchers at Johns Hopkins University School of Medicine and La Trobe University, the observational study followed participants in Maryland over a …
Study: Extending Photoperiod in Final Weeks Boosts Marijuana Yields Without Reducing Cannabinoid Levels
Extending the daily light cycle during the final two weeks of cultivation may increase marijuana yields without diminishing cannabinoid content, according to a new study published in Industrial Crops and Products. For the study, researchers at Wageningen University and Research conducted a detailed series of experiments using the THC-dominant ‘White Russian’ cultivar. The study aimed …
Study: THC and CBD Combination Reduces Inflammation Triggered by Viral Immune Receptors
New research published in the European Journal of Pharmacology found that THC and CBD—especially when combined in equal parts—can significantly reduce inflammation in human immune cells triggered by toll-like receptors 7 and 8 (TLR7/8), key components of the body’s response to viral RNA. Conducted by scientists at the University of Dublin, the study explored how …
Study: Cannabidiol Reduces Seizures and Extends Lifespan in Animal Model of Rare Genetic Epilepsy
Researchers have found that cannabidiol (CBD) significantly reduces seizures and extends survival in a mouse model of developmental and epileptic encephalopathy type 1 (DEE1), a rare and drug-resistant pediatric epilepsy. The study, published in Epilepsia, involved a collaboration between researchers from the National Research Council of Italy, the University of Cassino and Southern Lazio, the …
Study: Cannabis Use Associated With Lower Risk of Vision-Threatening Complication After Retinal Detachment Surgery
A new study in JAMA Ophthalmology found that people who used cannabis were less likely to develop proliferative vitreoretinopathy, a serious complication that can cause retinal detachment surgeries to fail. Researchers from Baylor College of Medicine, Stanford University School of Medicine, and the Palo Alto Medical Foundation conducted a large retrospective cohort study using electronic …
