NCT ID NCT03972124

First seen May 07, 2026 · Last updated Jun 23, 2026 · Updated 5 times

Summary

This study tests whether CBD oil (a non-psychoactive cannabis compound) can reduce the number of headache days in people with chronic migraine. About 72 adults with a long history of migraines will receive either a low dose of CBD, a higher dose, or a placebo for several months. The main goal is to see if CBD leads to fewer headache days compared to placebo.
