In sintesi

The evidence for CBD as a standalone remedy for insomnia is mixed — some studies show benefits while others do not, so more research is needed before it can be confidently recommended.

Results are mixed across 9 studies, even at Grade A evidence level due to study volume
A 2025 meta-analysis found inconsistent effects of cannabinoids on sleep quality
Some studies used medicinal cannabis blends rather than pure CBD, complicating comparisons
Individual responses to CBD for sleep may vary significantly
