Study: Secondhand Cannabis Smoke Can Contaminate Hair With Detectable THC and CBD Levels
A new study published in Forensic Science International found that even brief, passive exposure to cannabis smoke can lead to detectable levels of THC and CBD in human hair—potentially complicating forensic drug testing. For the study, researchers from the University of Bologna exposed four volunteers to controlled cannabis smoke inside a car for 15 minutes …
Study: Hemp Infructescences Found to Be Viable Source of Essential Oils
A new study highlights the potential of hemp infructescences—typically discarded after seed harvesting—as a valuable and sustainable source of essential oils. Published in Industrial Crops and Products, the research analyzed the morphology and chemical profile of mature hemp infructescences to evaluate their suitability as raw material for essential oil (EO) extraction. Two types of material …
Study: Sustainable Hemp/Cotton Blended Yarn Successfully Produced for Knitwear Using Vortex Spinning
Researchers from the Bangladesh University of Textiles have successfully produced hemp/cotton blended yarns using the vortex spinning system, offering a sustainable alternative to traditional cotton textiles. The study focused on overcoming hemp’s natural limitations—its stiffness and coarseness—which typically reduce its spinnability. By blending hemp with cotton and using vortex spinning, the team was able to …
Study: California Marijuana Legalization Linked to Decline in Heavy Alcohol Use Among Middle-Aged Adults
A study published this week by the journal Addiction found that marijuana legalization in California may have contributed to a reduction in alcohol consumption, particularly among middle-aged adults. For the study, researchers from Kaiser Permanente and the University of California examined over 8 million alcohol screening results collected from more than 3.5 million patients at …
Study: Medical Marijuana Use Linked to Lower Emergency and Urgent Care Visits in Chronic Pain Patients, Better Quality of Life
Medical marijuana use may reduce reliance on emergency and urgent care services for individuals with chronic pain, according to a large new study published in the journal Pharmacy. Researchers from George Mason University analyzed health and survey data from more than 5,200 adults across 36 states who received medical marijuana certifications through a telehealth platform. …
Study: Off-Label CBD Treatment Significantly Reduces Seizures in Epilepsy Patients
A new study published in Neurological Research and Practice finds that off-label use of cannabidiol (CBD) in patients with various forms of refractory epilepsy can significantly reduce seizure frequency and is generally well-tolerated. Researchers from University Hospital Bonn, Philipps-University Marburg, Goethe-University Frankfurt, and University Medicine Frankfurt conducted a retrospective analysis of 108 patients treated with …
Study: Intranasal CBD Nanocarriers May Improve Seizure Control and Brain Targeting
New research suggests that delivering cannabidiol (CBD) through the nasal cavity using nanostructured lipid carriers (NLCs) may improve its effectiveness in treating epilepsy. Published in Molecular Pharmaceutics and conducted by researchers at Dalian University of Technology, the study aimed to bypass limitations of oral medications—such as first-pass metabolism and poor penetration through the blood-brain barrier—by …
Study: CBD May Block Addictive Effects of Cocaine and Caffeine, Targeting Brain Matrix Genes
According to a new study published in Addiction Neuroscience, cannabidiol (CBD) could protect against the behavioral effects of cocaine and caffeine when used together, by altering gene expression in a key brain region associated with reward. Researchers from Universidad de la República and the Biological Research Institute Clemente Estable in Uruguay conducted the study on …
Study: Strong Majority of IBD Patients Believe Cannabis and CBD Oil Help Manage Symptoms
A strong majority of people with inflammatory bowel disease (IBD) believe cannabis and CBD oil provide meaningful symptom relief, according to a new study published in the journal Academic Medicine. Researchers from Case Western Reserve University and affiliated institutions surveyed 139 individuals, including 93 IBD patients and 33 without the condition. Over half of IBD …
