Oklahoma City, OK Public Conduct: Public Marijuana Use (2026)

Section 30-471(a) declares smoking and vaping "a public nuisance and dangerous to public health" and bans it in any indoor place used by or open to the public, in zoos, in public parks whether indoors or outdoors, in indoor workplaces, on vehicles providing public transportation, at meetings of public bodies, in licensed nursing facilities, and in licensed child care facilities. Subsection (b) extends the ban outdoors across all City-owned or City-operated property, including City trails posted with signage, with narrow carve-outs for public golf courses and licensed horse-racing facilities. Subsection (f) is the marijuana-specific hook: "The prohibition or regulation of smoking or vaping as established in this Article shall include the smoking or vaping of any marijuana product." Section 30-470 defines "marijuana product" broadly as any product containing cannabinoids derived from the cannabis plant or its resin, including synthetic cannabinoids and cannabis plant material, so the ban covers flower, concentrates, and vapor cartridges alike.

Unlike the article's ordinary exemptions for stand-alone bars, cigar bars, and up to 25 percent of a hotel's guest rooms under § 30-472, none of those carve-outs apply to marijuana: the exemption section opens with "Except for smoking or vaping of any marijuana product," stripping marijuana consumption of every exception the article otherwise allows tobacco smokers. The same exclusion appears in § 30-473's designated smoking-room provisions, which likewise do "not include or permit the smoking or vaping of any marijuana product." Property owners and operators must post signs at least four inches by two inches at each entrance under § 30-474 identifying the prohibition, with responsibility falling on the owner or lessee of private facilities and the manager or supervisor of corporate or public facilities.
