March 25, 2024 – CBD presents consumers with a big problem,” said Professor Chris Eccleston, who led the research from the Centre for Pain Research at Bath. “It’s touted as a cure for all pain, but there’s a complete lack of quality evidence that it has any positive effects.”

CBD products sold directly to consumers may contain chemicals other than CBD, some of which may be harmful and some illegal in some jurisdictions. Such chemicals include THC (tetrahydrocannabinol), the main psychoactive component of the cannabis plant.

Of the 16 randomized controlled trials that have explored the link between pain and pharmaceutical-grade CBD, 15 have shown no positive results, with CBD being no better than placebo at relieving pain.

A meta-analysis (which combines data from multiple studies and plays a fundamental role in evidence-based health care) links CBD to increased rates of serious adverse events, including liver toxicity.
