CBD oil put to the test for breast cancer joint pain
NCT ID NCT06787118
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial tests whether CBD oil can reduce joint pain caused by aromatase inhibitors, a common hormone therapy for early breast cancer. About 130 participants will receive either CBD or a placebo for 12 weeks, then switch treatments. The study measures pain interference and joint stiffness to see if CBD offers real relief.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- CBD oil (cannabidiol oral solution)
- What this could lead to
- If it works, this could provide a new, non-addictive option to ease joint pain for breast cancer patients on hormone therapy, improving their quality of life.
- What could go wrong
- This is a single-center study with only 130 participants, so results may not apply to everyone. CBD may cause side effects like drowsiness or liver issues, and the placebo effect could be strong for pain relief.
