Small CBD trial found no significant reduction in trauma-script reactivity
Randomized double-blind placebo-controlled trial
Published Jul 3, 2024 · Verified Oct 10, 2026
Study overview
A trial in 42 trauma-exposed participants with elevated stress found no statistically significant reduction in anxiety, distress or heart-rate response to personalized trauma scripts, either after initial CBD administration or one week of repeated administration.
Evidence & interpretation
Participants were assigned oral CBD or placebo. The study's measured outcomes did not show significant benefit relative to placebo; broader claims require additional controlled evidence.
Limitations
Small sample, short duration and a specific laboratory task. A non-significant result does not prove there is no effect under every condition and does not establish treatment efficacy.
