TL;DR
Recreational cannabis is illegal in Oklahoma. Licensed medical patients can carry 3 ounces, keep 8 ounces at home, and grow 6 mature plants and 6 seedlings. Without a license, having up to 1.5 ounces can be a $400 fine if you can state a medical condition. The 2023 legalization vote failed, and a 2025 petition was withdrawn.
Oklahoma voters approved medical cannabis with State Question 788 in 2018. The law has no list of qualifying conditions, so any doctor can recommend it, and Oklahoma quickly grew one of the largest markets in the country. Recreational cannabis is still illegal: voters rejected SQ 820 in 2023. The Oklahoma Medical Marijuana Authority (OMMA) regulates the program.

Medical cannabis in Oklahoma
Adults need a recommendation from an Oklahoma-licensed physician, then apply to OMMA for a patient license. There's no list of required conditions. Out-of-state patients can get a temporary license.
| Limit | Medical patients |
|---|---|
| On you | Up to 3 ounces of flower |
| At home | Up to 8 ounces of flower |
| Concentrate | Up to 1 ounce |
| Edibles | Up to 72 ounces |
| Home grow | Up to 6 mature plants and 6 seedlings |
Home grows must be on property you own or have the owner's written permission to use, and can't be visible from the street. Making concentrates at home with butane or other hazardous solvents is banned.
Taxes on cannabis in Oklahoma
Medical purchases carry a 7% excise tax plus state and local sales tax.
Driving and work
Driving while impaired is illegal, including for patients. Oklahoma law gives patients some protection from being fired just for having a license, but employers can ban use and impairment at work, and safety-sensitive jobs are exempt.
Is anything changing in 2026?
No recreational measure is on the 2026 ballot. A citizen petition (SQ 837) was withdrawn in 2025 after organizers said they wouldn't get enough signatures under Oklahoma's new, stricter petition rules. The state continues to tighten oversight of medical licenses.
Federal law in 2026
Federal law still treats recreational cannabis as illegal. In April 2026, the federal government moved marijuana sold under a state medical license (and FDA-approved cannabis medicines) to Schedule III, but adult-use cannabis is still Schedule I. That means it's still banned on federal land and can't legally cross state lines, even between two legal states.
Separately, a federal ban on intoxicating hemp products takes effect in two steps: synthetic and converted cannabinoids like delta-8 lose their legal status on November 12, 2026, and naturally derived hemp THC (THCA flower, hemp delta-9 edibles and drinks) on December 11, 2026.
