Researchers from NICM Health Research Institute are seeking participants to be involved in a clinical trial investigating the efficacy and safety of two different medicinal cannabis products in people with endometriosis. The study will explore whether medicinal cannabis helps with pelvic pain severity, fatigue, quality of life, and mental wellbeing.
The trial will involve 126 patients, living in New South Wales, who will be monitored by researchers to learn whether medicinal cannabis improves outcomes for people with endometriosis.

Who can participate?
You may be eligible to participate if:
- You have endometriosis (confirmed either via laparoscopy, MRI or ultrasound),
