Hundreds of peer-reviewed cannabis-related studies have been published already in 2026, highlighting the continued growth of scientific interest in marijuana, cannabinoids, hemp and the endocannabinoid system.
The studies cover a wide range of topics, including cancer, chronic pain, inflammation, neurological disorders, addiction, HIV, metabolic health, veterinary medicine, product testing, cultivation and industrial hemp uses. Many focus on cannabidiol (CBD), while others examine THC, CBG, CBC, THCV, CBN, terpenes, cannabis oils, hemp seed compounds and marijuana policy.
With that in mind, below are over 100 peer-reviewed cannabis studies, all published in 2026.
THC and CBD May Strengthen Cisplatin’s Effects Against Cervical Cancer Cells
Researchers found that THC and CBD enhanced the anti-cancer effects of cisplatin in cervical cancer cells, suggesting cannabinoids may help improve the effectiveness of the chemotherapy drug.
CBD Triggers Anti-Cancer Effects in Breast Cancer Cells, Including Drug-Resistant Line
A new study found that CBD triggered anti-cancer effects in both standard and drug-resistant breast cancer cells, including reduced viability, cell cycle disruption and increased apoptosis.
Marijuana Use Linked to Lower Risk of Several Metabolic Conditions
A large study found that marijuana use was associated with a modestly lower risk of several metabolic conditions, including hypertension and type 2 diabetes, although the relationship varied significantly depending on body mass index.
Cannabinoid Compound Reduces Asthma-Related Airway Inflammation
Researchers found that a cannabinoid-based compound reduced airway inflammation and improved respiratory markers in a model of asthma, pointing to potential therapeutic use in inflammatory lung disease.
CBD May Strengthen Effects of Breast Cancer Drug
A recent study found that CBD may strengthen the effects of a breast cancer drug, with the combination producing greater anti-cancer activity than the drug alone in lab testing.
CBD Shows Benefit for Schizophrenia Symptoms
A new review found that CBD showed potential benefit for schizophrenia symptoms, particularly in reducing psychotic symptoms, while also appearing to be well tolerated compared to many conventional treatments.
CBD Reduces Heroin-Seeking Behavior by Reversing Brain Changes Linked to Relapse
Researchers found that CBD reduced heroin-seeking behavior in an animal model by reversing brain changes associated with relapse vulnerability, supporting its potential role in addiction treatment.
CB1 Activation Promotes Myelin Repair in Multiple Sclerosis Model
A new study found that activating the CB1 receptor promoted myelin repair and improved neurological recovery in a model of multiple sclerosis, highlighting a possible new target for treating demyelinating disease.
CBD Reduces Inflammation in Canine Mammary Cancer Cells
Researchers found that CBD reduced inflammatory signaling in canine mammary cancer cells without harming cell viability, pointing to potential therapeutic value for one of the most common cancers affecting female dogs.
Minor Cannabinoids Show Distinct Effects on Pain-Sensing Neurons
A new study found that several minor cannabinoids produced distinct effects on pain-sensing neurons, suggesting these lesser-known compounds may influence pain pathways in different and potentially useful ways.
Cannabis Seed Feed Boosts Chicken Nutrition Without Impacting Growth
Researchers found that adding cannabis seed to chicken feed improved nutritional quality without negatively affecting growth, suggesting it may serve as a useful feed ingredient in poultry production.
CBD Blocks HIV Infection Pathways in Immune Cells, Shows Potential as Preventative Therapy
A recent study found that CBD blocked key HIV infection pathways in immune cells, pointing to its potential as a preventative therapy targeting early stages of viral transmission.
Cannabinoid-Silver Combination Shows Potent Activity Against Drug-Resistant Bacteria
A new study found that a three-part combination of silver, CBC and CBG produced strong antibacterial and anti-biofilm effects against drug-resistant pathogens including MRSA, E. coli and Pseudomonas aeruginosa, while also reducing the amount of silver needed.
CBD May Help Reverse Cognitive Decline Linked to Olanzapine and High-Fat Diet
Researchers found that CBD may help counter cognitive decline tied to olanzapine use and a high-fat diet, with effects in rats that were comparable to a commonly used metabolic drug.
Cannabinoid Compounds Trigger Ferroptosis in Aggressive Brain Cancer Cells
A recent study found that two synthetic cannabinoid compounds reduced glioblastoma cell viability by triggering ferroptosis, an iron-dependent form of cell death linked to oxidative stress and lipid peroxidation.
