A survey of Australian women with endometriosis found that 76% of those who self-managed with cannabis noticed effective pain reduction and 56% were able to reduce pharmaceutical medications by at least half:
The study’s objective was to determine the prevalence, tolerability, and self-reported effectiveness of cannabis in women with endometriosis.
A cross-sectional online survey was conducted between October and December 2017.
Recruitment targeted women with endometriosis through social media postings from endometriosis advocacy groups.
Women aged 18 to 45, living in Australia, and with surgically confirmed endometriosis were eligible to participate.
Survey questions investigated the types of self-management used, change in symptoms or medication use, costs, and adverse events.
A total of 484 responses were included for analysis, with 76% of the women reporting the use of general self-management strategies within the last 6 months. Of those using self-management, 13% reported using cannabis for symptom management. Self-reported effectiveness in pain reduction was high (7.6 of 10), with 56% also able to reduce pharmaceutical medications by at least half.
Women reported the greatest improvements in sleep and in nausea and vomiting. Adverse effects were infrequent (10%) and minor.
Australian law currently requires legal medicinal cannabis use to follow specific, regulated pathways that limit prescription by this method; however, self-reported illicit use of cannabis remains relatively common in Australian women with endometriosis. Women report good efficacy of cannabis in reducing pain and other symptoms, with few adverse effects reported.
Further clinical research is warranted to determine the effectiveness of cannabis in managing endometriosis symptoms. In locations where medicinal cannabis is more accessible, there remains a paucity of evidence for its clinical efficacy with endometriosis-associated symptoms.
