In Oklahoma, a new law effective November 1, 2025, specifically addresses carrying THC/ma*****na in a car: it is illegal to have an open container of ma*****na in the passenger area of a motor vehicle. This is a misdemeanor offense.
Additionally, other laws and existing regulations govern the transport of THC in a vehicle:
New Law (Effective November 1, 2025)
Open Containers: It is unlawful for a person operating a motor vehicle to possess any open container that contains ma*****na in the passenger area of the vehicle.
Consumption: Consuming ma*****na or inhaling secondhand smoke while operating a motor vehicle on a public road is also illegal.
Minors Present: A separate new law (also effective November 1, 2025) makes it unlawful to knowingly smoke to***co or ma*****na in a vehicle while a minor is present.
Existing Regulations for Medical Cardholders
For individuals with an Oklahoma medical ma*****na license, the following rules apply to transporting THC products:
DUI Laws: It is illegal to drive a motor vehicle while under the influence of ma*****na, regardless of having a medical card. Oklahoma has a zero-tolerance law for any detectable amount of a Schedule I substance in a driver's system, which includes THC metabolites.
Packaging: All medical ma*****na products must be transported in a container that is clearly labeled "For use by licensed medical ma*****na patients only" and "Keep out of reach of children". New packaging requirements taking effect November 1, 2025, also mandate the label to state: "It is illegal to drive a motor vehicle while under the influence of ma*****na or ma*****na products".
Storage: While not explicitly required for individual patient transport, best practice is to transport medical ma*****na in a secured area of the vehicle not accessible to the driver during transit (e.g., the trunk) to avoid potential issues.
In summary, ensure any THC product is in a closed container, ideally in the trunk, and never consume it while driving or with a minor present in the vehicle.
