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

We are recruiting 20 participants aged 14-17 who have been diagnosed with chronic headaches and have failed other treatments.

Participants will administer CBD-enriched cannabis herbal extract oil twice per day, will attend 7 in-clinic visits and will complete daily electronic headache diaries.

We have begun recruitment in Toronto, Vancouver and Halifax.
