This bill authorizes counties in Oklahoma to levy an excise tax on retail medical marijuana sales, capped at ten percent of the gross amount received by sellers. The tax must be approved by a majority of registered voters in the county through a special election, which can be initiated by a resolution from the county commissioners or by an initiative petition signed by at least five percent of registered voters. If the tax is not approved, the county cannot hold another election on the matter for six months. The proceeds from this tax are designated for public safety and infrastructure and must be deposited into the county's general revenue or a specific revolving fund.

Additionally, the bill allows cities and towns to impose a similar excise tax on medical marijuana sales, also limited to ten percent of gross receipts, with the same purpose of funding public safety and infrastructure. The bill specifies that the duration of the tax can be either limited or unlimited, and this duration must be clearly identified when presented to voters. The act is set to take effect on November 1, 2026.
