Oklahoma Cannabis Laws & Regulations

Oklahoma was one of the last states to join the United States in 1907, being the 46th state. Home to the Cherokee and Choctaw tribes, Oklahoma derives its name from the Choctaw okla and humma, meaning “red people”. Its unofficial nickname is the Sooner State, after the state's pioneers who came to Oklahoma to create their home.

Oklahoma boasts a diverse culture, with over 25 native languages spoken across the state. Its largest and most well-known city, Oklahoma City, is also the state capitol. Home to beautiful landscapes such as the Ouachita Mountains and the Black Kettle National Grassland, Oklahoma has plenty of wide-open plains and rolling hills. Oklahoma is also home to the Trail of Tears and the Santa Fe Trail, two important historical landmarks.

Cannabis became prohibited in the state of Oklahoma in 1933, and it wasn’t until 85 years later in 2018 that the state legalized medical marijuana for sale and use. As of March 2022, Oklahoma currently has over 381,000 medical marijuana patients, 8,184 cannabis growers, and 2,285 cannabis retailers. Activists in the state are working on measures for legalizing the recreational sale and use of cannabis, which may be up for a vote on the 2022 ballot.

Weed Legalization in Oklahoma

Cannabis was a banned substance in Oklahoma from 1933 to 2018. Hemp CBD oil containing less than 0.3% THC was the first to become legal in Oklahoma in April 2015. In 2015, advocates of cannabis legalization began a petition to add medical marijuana to the 2016 ballot. After some trouble with the bill's language, the vote was delayed until June 2018, when it passed with 57% in favor.

The passing of Oklahoma State Question 788, the Medical Marijuana Legalization Initiative, legalized medical marijuana in Oklahoma and led the state to create the Oklahoma Medical Marijuana Authority (OMMA). The state continues to refine its medical cannabis program, with the most recent OMMA emergency rules passed in November 2021. Among other things, the emergency rules limit the size of pre-rolls to 1 gram or less and prohibit growers or dispensaries from making or packaging infused pre-rolls. The permanent rules became effective in Jan. 2024 and kept this and other restrictions in place.

As of 2024, the consumption of cannabis is legal for medicinal use only in the state of Oklahoma.
