UPDATE: This study has now closed. We will share results when they become available.

This study examines the safety of a CBD-enriched herbal extract oil to see what effect it has on participants and their headaches.

We aimed to recruit 20 participants ages 14-17 who have been diagnosed with chronic headaches and have failed other treatments.

Participants administered CBD-enriched cannabis herbal extract oil twice per day, attended 7 in-clinic visits and completed daily electronic headache diaries.
