For now, Oklahoma is a medical-only state. Residents voted to legalize a medical program in 2018 through Ballot Question 788. The good news is that the bill offered significant possession and cultivation allowances. Medical patients aged 18 or older are allowed to possess up to 8 ounces of weed at home, 3 ounces on their person, and an ounce of concentrated cannabis at home. Additionally, they can have up to 72 ounces of edibles. Cultivation is also allowed, with patients allowed to grow up to six plants, including six mature and six immature plants. However, non-medical marijuana remains illegal, and you can face prosecution for possession outside of the medical framework. Oklahoma does not have reciprocity laws accepting medical patients from other states, so your out-of-state medical card won't work at Oklahoma dispensaries.
