Oklahoma Cannabis Laws 2026: The Modern Era
State regulators have continued efforts to tighten licensing and enforcement after years of rapid, largely unrestricted market growth.
2026 (Current Status)
2026 (Current Status): Oklahoma remains a medical-only state with one of the largest numbers of licensed dispensaries and growers per capita in the country. Recreational cannabis remains illegal following the failed 2023 ballot measure.
The Failed Recreational Vote: State Question 820 (2023)
2023 (March)
2023 (March): Voters reject State Question 820, a measure that would have legalized recreational marijuana for adults 21 and older, in a special election.
Medical Marijuana Legalization: State Question 788 (2018)
Oklahoma's medical marijuana law is notably broad, requiring only a physician's recommendation rather than a specific list of qualifying conditions.
2018 (June)
2018 (June): Voters approve State Question 788, legalizing medical marijuana with one of the least restrictive qualification standards in the nation.
2018–2020
2018–2020: Licensing opens rapidly, and Oklahoma quickly becomes home to one of the largest numbers of licensed medical marijuana businesses of any state.
