Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether taking CBD can reduce PTSD symptoms. It also looks at whether the dose matters.
- Who it's for
- You may be able to join if you have PTSD, and half of the participants also have a mild traumatic brain injury.
- What's involved
- You will take a pill every day for 8 weeks. The pill could be low dose CBD, high dose CBD, or a pretend pill with no medicine. You will have check‑ins to see how you feel and to measure your PTSD symptoms.
- Time commitment
- The study lasts 8 weeks and includes daily pill taking and several visits to the clinic for assessments.
- Phase 2: a mid-size study of how well it works
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance.
