Summary
This Phase 3 study tests whether nightly doses of CBD (75mg or 150mg) can reduce insomnia severity in adults over 8 weeks. Participants take capsules or a placebo, and researchers measure changes in sleep quality using a standard questionnaire and sleep efficiency. The goal is to provide reliable evidence on whether CBD is a safe and effective option for managing insomnia.
