Full Breakdown

Under 63 O.S. Section 420 et seq., implementing State Question 788 (2018), Oklahoma medical marijuana patient license holders may possess up to six mature plants and six seedlings for personal medical use. Cultivation must occur on property owned or leased by the patient, in a location not visible from public space. The Unity Bill (HB 2612) clarified that municipalities may regulate commercial cannabis through zoning but cannot prohibit medical patient cultivation outright or require additional patient permits. Recreational cultivation remains illegal in Oklahoma. Plants must be secured from minors, and rental tenants need landlord consent.

Violations & Penalties

Exceeding the 6+6 plant limit, public visibility, or growing without a valid OMMA patient license can result in criminal possession or cultivation charges and license revocation.
