Marijuana plants exposed to a bioacoustic protocol produced nearly twice as much usable dry flower as untreated plants in a new cultivation study. The study, conducted by Robert Flannery, PhD, of Dr. Robb Farms in California, examined the Bioacoustic Cultivation and Communication Protocol (BCCP), a sequence of sound signals developed by Haivya, Inc. The paper was …

Study: Cannabis Extract Reduced UVB-Induced Oxidative Stress in Melanoma Cell Model
A cannabis extract rich in neutral cannabinoids significantly reduced ultraviolet B (UVB)-induced oxidative stress and partially restored a key regulator of pigment-producing cells, according to a new laboratory study. The study, published in BMC Complementary Medicine and Therapies, was conducted by researchers from Mahidol University and Thailand’s National Science and Technology Development Agency. Researchers said …
Study: California Adult Marijuana Use Remained Largely Stable After Retail Sales Began, While Edible Use Rose
Adult marijuana use in California remained largely stable during the seven years following the launch of licensed recreational sales, although consumption shifted away from smoking and toward edibles, according to a new study. The study, published in the Journal of Cannabis Research, was conducted by researchers from the University of California, San Diego’s Center for …
Study: CBD Triggered Cell Death and Disrupted Growth in Fibrosarcoma Cells
Cannabidiol (CBD) triggered programmed cell death and disrupted cell-cycle progression in human fibrosarcoma cells, according to a study published online by the Journal of Cannabis Research. Fibrosarcoma is a rare and aggressive cancer that develops in fibrous connective tissue and can be difficult to treat once it becomes advanced or metastatic. For the study, researchers …
Study: Cannabis Oral Spray and Cannabis Tea Improved Spasticity, Spasms and Pain in Multiple Sclerosis Patients
Both a cannabis-based oral spray and a cannabis decoction (tea) significantly improved spasticity, muscle spasms and pain in people with multiple sclerosis, according to a new study published in Multiple Sclerosis and Related Disorders. Researchers from Azienda Sanitaria Universitaria Giuliano Isontina, the University of Trieste and Fondazione IRCCS Istituto Neurologico Carlo Besta, all in Italy, …
Study: Cannabis Flower Extracts Inhibited Multiple Alzheimer’s-Related Enzymes and Protected Cells From Damage
Cannabis flower extracts inhibited several enzymes associated with Alzheimer’s disease while protecting neuron-like cells from oxidative and amyloid-related damage, according to a study published in Journal of Cannabis Research. Researchers from the MIGAL – Galilee Research Institute and Tel-Hai University in Israel examined ethanol extracts derived from four cannabis chemovars. Three contained relatively balanced levels …
Researchers Develop Microbial Process That Produces Spinnable Hemp Fiber in Seven Days
Researchers from Ege University in Türkiye say they’ve developed a controlled microbial process that extracts usable textile fiber from hemp in seven days, cutting the time required by conventional water retting roughly in half. Their findings were published in a study (PDF) in AUTEX Research Journal. The team used bacteria isolated from hemp-retting water in …
Clinical Trial: CBD Provided Pain Relief Comparable to Codeine-Acetaminophen After Laser Eye Surgery
Oral cannabidiol (CBD) provided pain relief comparable to codeine-acetaminophen following laser eye surgery, according to a randomized clinical trial published in the Journal of Cataract & Refractive Surgery. Researchers from the University of Florida compared low-THC oral CBD with codeine-acetaminophen for controlling postoperative pain following photorefractive keratectomy (PRK), a laser procedure used to correct nearsightedness, …
CBD Oil Was Well Tolerated in Dogs With Osteoarthritis, Clinical Trial Finds
Cannabidiol (CBD) oil was well tolerated by dogs with osteoarthritis, according to a new clinical trial. Researchers from University College Dublin conducted the randomized, double-blinded, placebo-controlled crossover study, which has been posted as a preprint while under consideration by Irish Veterinary Journal. The study involved 10 dogs with osteoarthritis confirmed through diagnostic imaging. Each dog …
CBD Nanoparticles Suppressed Liver Tumor Growth in New Study
Cannabidiol (CBD) delivered through specially designed nanoparticles significantly inhibited liver tumor growth in mice, performing comparably to a commonly used chemotherapy drug, according to a study published in the Journal of Drug Delivery Science and Technology. Researchers developed microscopic drug carriers designed to overcome one of the primary obstacles to using CBD therapeutically: its extremely …
