Discrete choice experiment on Australian public preferences for provision of medicinal cannabis

A new study found Australians prefer medicinal cannabis as a complementary option rather than last resort, with strong support for prescribing at any treatment stage. Preferred oral formulations and lower THC levels were favored, while cost was a critical issue, with many advocating for government subsidies.
