CBD safety trial for athletes: could it protect against concussion?

NCT ID NCT06204003

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This completed Phase 1 study tested whether a high-CBD hemp extract is safe for healthy male athletes in contact sports. Thirty-four participants took increasing daily doses of CBD (up to 30 mg per kg of body weight) over several weeks. Researchers monitored brain and heart function, side effects, and how the body processes CBD. The goal was to check safety, not to prove it prevents or treats concussion.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

high-CBD cannabis/hemp isolate extract (99% CBD, 0.1% THC)

What this could lead to

If safe, this could support larger studies on CBD for concussion protection and pain management in athletes.

What could go wrong

This is a very early Phase 1 safety study with only 34 healthy athletes. It does not test effectiveness for concussion or pain, and results may not apply to the general public.
