Below is a breakdown of more than 70 studies published in 2026 covering cannabis and compounds such as CBD, THC and CBG. The findings span pain relief, cancer, brain injury, sleep, metabolism, inflammation, wound healing and industrial hemp applications, underscoring just how broad the field has become. The title of each section below links to a full article on The Marijuana Herald.
Clinical Trial: Cannabis-Based Herbal Formula Matches Lorazepam for Chronic Insomnia Relief
A clinical trial found that a cannabis-based herbal formula performed similarly to lorazepam in relieving chronic insomnia, while also showing potential benefits for sleep quality and related symptoms.
Hemp Seed Compounds Show Potential for Treating Diabetes and Obesity
Researchers found that two hemp seed hull compounds, Cannabisin A and Cannabisin B, improved blood sugar control and restored key metabolic signaling tied to diabetes and obesity in cell, liver and mouse models.
Study: CBD Triggers Cell Death in Breast Cancer Cells Through Multiple Molecular Pathways
A new study found that CBD reduced breast cancer cell viability and triggered cell death through several interconnected pathways involving oxidative stress, mitochondrial dysfunction and apoptosis.
CBG-Dominant Cannabis Extract Reduces Fat Cell Formation and Boosts Fat Burning
Researchers found that a CBG-dominant cannabis extract reduced the formation of fat cells while increasing markers tied to fat breakdown and energy expenditure in a lab model.
Exosome-Based Oral CBD Slows Aggressive Triple-Negative Breast Cancer
A study published in Cancer Letters found that an exosome-based oral CBD formulation improved tumor targeting and slowed the growth of aggressive triple-negative breast cancer in mice, while also altering the activity of more than 1,000 genes tied to cancer progression.
Marijuana Flower Shows Neuroprotective and Pain-Relieving Effects in Alzheimer’s Model
A study published in Frontiers in Pharmacology found that marijuana flower produced strong pain-relieving and neuroprotective effects in an animal model designed to mimic both Alzheimer’s-related cognitive impairment and chronic neuropathic pain.
Multiple Cannabis Compounds Found to Target Key Skin Cancer Growth Pathways
A new study found that numerous cannabis-derived compounds may interfere with major skin cancer growth pathways tied to proliferation, invasion and metastasis.
Marijuana Use Linked to Lower Opioid Need After Wrist Fracture Surgery
New research published in the Journal of Surgical Orthopaedic Advances found that patients who used marijuana required significantly fewer opioids after distal radius fracture surgery while reporting pain control comparable to non-users.
CBD-Derived Compound Shows Potential to Treat Bladder Dysfunction After Spinal Cord Injury
A study published in Life Sciences found that the CBD-derived compound CIAC001 improved bladder function, reduced neuroinflammation and helped restore bladder-related nerve pathways in mice with spinal cord injury.
THC and CBD Combination Reduces Pain, Improves Jaw Function in Patients With Chronic TMD
A study in adults with chronic temporomandibular disorder found that a balanced THC/CBD treatment significantly reduced pain and improved jaw mobility, with functional pain falling by roughly 90%.
What Marijuana’s Move to Schedule III Will and Will Not Change Under Federal Law
A new policy analysis found that moving marijuana to Schedule III would mark the biggest federal marijuana policy shift in decades, but it would still fall well short of legalization and would not automatically make state markets federally lawful.
Hemp Protein Cuts Cholesterol by Nearly 40% in Lab Tests
A new study found that a modified hemp protein reduced total cholesterol by nearly 40% and triglycerides by more than 30% in lab testing, while also increasing HDL cholesterol.
Optimized CO2 and Ventilation Boost Cannabis Micropropagation Biomass by Up to 282%
Researchers found that carefully balancing carbon dioxide levels and air exchange dramatically improved the growth of medicinal cannabis plantlets, with the biggest gains coming under elevated CO2 and moderate ventilation.
CBD and Bevacizumab Combo Reduces Lung Cancer Cell Growth by Over 50%
Researchers found that combining CBD with bevacizumab significantly increased cancer cell death in a lab model of non-small cell lung cancer, pointing to potential benefits from the two-drug approach.
Hundreds of Industrial Uses for Marijuana Plant Waste
A review of 262 studies found that marijuana plant waste may have significant industrial value, with potential uses spanning textiles, bioplastics, fuels and food products.
No Significant Driving Impairment Found 12 to 15 Hours After Marijuana Use in Frequent Consumers
A new study found that frequent marijuana users did not show measurable driving impairment 12 to 15 hours after use, even when THC remained detectable in blood and oral fluid.
CBD Shows Anti-Tumor Effects in Burkitt Lymphoma Cells
Researchers found that CBD may help slow the growth of Burkitt lymphoma cells and reduce a key cancer stem cell marker, suggesting potential anti-tumor effects in this aggressive cancer type.
Even 1 to 5 mg of THC Can Trigger a Positive Urine Test Weeks After Use, Study Finds
A recent study found that even very small amounts of THC can lead to a positive urine test for days or even weeks, underscoring how low-dose exposure may still carry drug-testing consequences.
Study: Cannabis Drinks Linked to 50% Drop in Alcohol Use, University at Buffalo Study Finds
Researchers found that adults who used cannabis-infused beverages during a monitored drinking period cut their alcohol intake by about half, suggesting the products may serve as a substitute for some drinkers.
Clinical Trial Finds CBD Suppositories May Ease Menstrual and Pelvic Pain
A clinical trial found that CBD suppositories were associated with reductions in menstrual and pelvic pain symptoms, pointing to a potential new localized treatment approach.
