Brief Summary

Chronic headaches are a major cause of disability among adolescents. Cannabis products have supported the management of headaches in adults and may play a role in pediatric chronic pain. We propose a multisite, open-label, tolerability study conducted across three centers in Canada of Cannabidiol-enriched Cannabis Herbal Extract in adolescents (ages 14 to 17 years old) with chronic headaches. The study includes a one month baseline assessment, four months of escalating treatment doses and a weaning period. Our primary outcome is tolerability defined as the number and severity of reported adverse events.
