A survey of cost, access and outcomes for cannabinoid-based medicinal product use by Australians with endometriosis.

People with endometriosis use cannabis to manage their symptoms. This study aimed to identify costs, modes of administration, product composition, and self-reported effectiveness for those accessing medicinal cannabis in Australia. There were 192 survey responses analysed. Most (63.5%) used a 'cannabis clinic' doctor, incurring an initial consultation cost of $100-$200+ (10.2% Medicare bulk-billed) and median cannabinoid medicine costs of $300AUD per month. Cost was a major barrier to access, necessitating reducing dosage (76.1%) and/or consuming illicit cannabis (42.9%), despite a prescription. Most (77%) medical consumers used two or more cannabis products, with delta-9-tetrahydrocannabinol predominant oil and flower products most frequently prescribed.
