The pace of cannabis research in 2025 has been unprecedented. Through the end of August, scientists around the world have released hundreds of peer-reviewed studies exploring nearly every facet of the plant and its compounds. This wave of research reflects both a growing acceptance of marijuana as a subject of serious academic inquiry and the …

Study: CBDA Shows Far Greater Bioavailability Than CBD in Animal and Cell Models
Researchers from the University of Chemistry and Technology Prague and the Institute for Clinical and Experimental Medicine have found that cannabidiolic acid (CBDA) has far stronger bioavailability than cannabidiol (CBD), making it a potentially underutilized therapeutic compound. The study, which is being published in the November 2025 issue of the International Journal of Pharmaceutics, tested …
Study: No Significant Change in Car Accidents Following Cannabis Legalization in Connecticut
A new peer-reviewed study has found that Connecticut’s move to legalize recreational cannabis in 2023 did not lead to an increase in car accidents, either across the state or in neighborhoods surrounding dispensaries. Published in Cannabis and Cannabinoid Research and made available online by the U.S. National Library of Medicine, the research adds to the …
Study: 1 in 12 U.S. Cancer Survivors Use Marijuana, Nearly Half for Medical Purposes
A nationwide analysis has found that roughly 1 in 12 cancer survivors in the United States use marijuana, with medical use being far more common among this group than the general population. The study, published in JCO Oncology Practice, reviewed survey data from more than 82 million adults across 23 states who responded to the …
New Study Identifies Universal Genetic Marker for Early Sexing of Marijuana Plants
Researchers from University College Dublin have developed what they call a breakthrough method to determine the sex of cannabis plants at an early stage of growth. The study, published in Planta, introduces CsPDS5, a highly conserved genetic marker that enables precise, affordable, and reliable sex identification using a simple PCR-based assay.
Study Finds Cannabinoids Show Potent Anti-Biofilm Activity Against MRSA
According to the results of a new study published in the Journal of Applied Microbiology, several cannabinoids, including CBN, THC, CBG, CBC, and CBD, demonstrate significant activity against methicillin-resistant Staphylococcus aureus (MRSA) biofilms, a major source of hospital-acquired pneumonia. Researchers evaluated the five main phytocannabinoids for their effects on MRSA biofilms using crystal violet staining, …
Study: CBD and Low-Dose Radiation Show Protective Effects Against Hepatic Encephalopathy
A study published recently in the peer-reviewed journal Immunopharmacology and Immunotoxicology finds that cannabidiol (CBD), alone or combined with low-dose ionizing radiation (LDR), may help protect against brain and liver damage linked to hepatic encephalopathy (HE). Hepatic encephalopathy, a condition stemming from severe liver dysfunction, can trigger inflammation, oxidative stress, and cognitive decline. To test …
Study: Vaporized Cannabis May Ease Naloxone-Induced Opioid Withdrawal Symptoms
A new proof-of-concept study published in Experimental and Clinical Psychopharmacology finds that vaporized cannabis may help reduce the severity of withdrawal symptoms triggered by naloxone, a medication commonly used to reverse opioid overdoses. Researchers from Columbia University and Johns Hopkins School of Medicine tested the effects of vaporized cannabis on a 52-year-old male participant with …
Study Finds THC and CBD Create Distinct Brain Activity Patterns
A new study published in the Journal of Psychopharmacology reports that THC and CBD produce markedly different effects on brain function, with THC increasing connectivity and blood flow while CBD decreases certain measures of connectivity without altering blood flow. Researchers from the University of Reading, Heinrich-Heine University, and King’s College London administered THC, CBD, and …
Nanoparticle Delivery of CBD Shows Strong Tumor Inhibition in Triple-Negative Breast Cancer
A study published today by Oxford Academic’s Journal of Pharmacy and Pharmacology finds that cannabidiol (CBD), when delivered through a folic acid-modified chitosan (FA-CS) nanoparticle system, significantly inhibited tumor growth in triple-negative breast cancer (TNBC), an aggressive form of the disease with few effective treatment options. Researchers from Sun Yat-sen University, Zunyi Medical University, and the …
