A new study shows inflammation may explain who benefits from CBD, highlighting why verified cannabinoid content and Certified CBD products matter more than ever.
Last year, almost 33% of Americans made a mental health-based New Year’s resolution, which was a 5% increase from the previous year. It shows we’re taking our mental health seriously and may mean we might be more likely to turn to supplements when stress and sleepless nights build up. Cannabis and CBD products often sit right in the middle of this conversation, as they claim to help calm the mind, restore sleep, and take the edge off anxiety. Even though those supposed benefits are sometimes included in marketing efforts, the scientific evidence about them remains mixed. These products have a history of working for some people and not for others, and now we might know why. A 2025 study in Frontiers in Behavioral Neuroscience offers valuable insights and suggests that differences in why CBD may or may not work for a person could be due to inflammation. If you’re a CBD brand or drug-tested athlete taking this product, this is what you need to know.
It can be tricky to know whether someone will get the benefits or whether their CBD will be a damp squib. To find out more, researchers tracked 171 adults with mild to high anxiety and gave them either THC-dominant, CBD-dominant, or balanced cannabinoid products. For 4 weeks, they used their products as they usually would at home and reported their changes in mood, stress, and sleep. They also gave blood samples to track their levels of inflammation. The results? It didn’t make much of a difference to any of it. Inflammation barely moved in any direction, regardless of what product someone used. However, there was a catch. What mattered wasn’t whether inflammation changed over time, but how inflamed someone was at the start of the study. People with the highest baseline inflammation showed the greatest improvements in sleep quality, while those with the lowest baseline inflammation showed smaller gains. The CBD-rich cannabinoid products were the most consistently effective across the full range of inflammation levels, while THC-heavy products varied depending on how inflamed a person already was.
If consumers expect CBD products to help with their sleep, stress relief, and mood, this study shows why consistency matters. It shows how uncontrolled, variable, or unlabeled THC content in a product can lead to unpredictable outcomes. A brand using CBD should recognize that according to this recent study customers may differ significantly based on their existing levels of inflammation.Some people might enjoy massive mprovements. Others may not change at all. Regardless of where someone falls, everyone deserves to know exactly what’s in a product, with the label giving them all they need to make an informed decision. Poorly manufactured or inaccurately labeled products erode consumers' trust and distort the emerging science in this space. Without precision quality, personalized and effective cannabinoid use might not be possible.
This is where BSCG’s Certified CBD program creates peace of mind for whatever the future science may hold. Every finished product lot is tested against BSCG’s industry-leading banned substance menu, which covers more than 450 drugs, while also verifying cannabinoid content and THC daily dose limits.Surveillance testing is conducted for environmental contaminants,including heavy metals, pesticides, and microbiological agents.Certification also evaluates GMP requirements, raw material specifications, and finished product testing. The results are made completely transparent, with the reports publicly available through BSCG’s database, allowing consumers and professionals to confirm quality for themselves. BSCG covers more drugs than any other certification provider, and more than 400 on the WADA Prohibited List, the best protection available today around the world. In a market where purity and accuracy can’t always be assumed, BSCG Certified CBD provides trust and reportable quality results for CBD products.
As more research like this emerges, it pushes the CBD conversation into new territory. It shows that one product is likely to work the same way for everyone because each person’s physiology is unique. CBD products are starting to build a consistent evidence base, but that can only translate into the real world if the products themselves are consistent. As CBD expands into the wellness,mental health, and sleep support markets, quality control might be the foundation for everything that comes next. When you verify purity, the exact amounts of active ingredients, and safety, they can become the focal point for any brand hoping to serve their consumers responsibly
