Senator George Burns (R) has prefiled Senate Bill 320 for the 2025 legislative session. The bill would establish a new purchase limit for medical marijuana patients in Oklahoma.
If enacted, SB 320 will amend existing state law to limit medical marijuana purchases to no more than two and one-half ounces (70.9 grams) within a one-week period. This provision will join the current regulations allowing licensed patients to legally possess up to three ounces of marijuana on their person and additional quantities in various forms, such as edibles and concentrates.
The measure, which will receive its first reading in the Oklahoma Senate on February 3, will leave other possession limits for plants and processed marijuana products unchanged.
The bill, if passed, will take effect on November 1, 2025.
Oklahoma currently leads the nation with the highest percentage of medical marijuana patients, with approximately 9.5% of the state’s population enrolled in the medical marijuana program. Oklahoma also boasts more dispensaries per capita than any other state, despite having a moratorium on new marijuana stores in place since 2023.
