Bill No. 39 amends various sections of the Oklahoma Statutes related to firearms, specifically addressing the carrying of weapons under the influence of alcohol and the eligibility criteria for obtaining a handgun license under the Oklahoma Self-Defense Act. Key changes include the prohibition of carrying firearms while under the influence of medical marijuana obtained through a valid patient license if it affects mental or physical processes. Additionally, the bill clarifies that being a lawful holder of a medical marijuana patient license cannot be the sole reason for denying an applicant's eligibility for a handgun license.

The bill also updates the language regarding eligibility conditions for obtaining a handgun license, replacing "Ineligible" with "Ineligibility" in certain contexts and modifying the language surrounding protective orders and mental health conditions. It establishes that individuals with a medical marijuana license cannot be denied a handgun license solely based on that status. The act is set to take effect on November 1, 2025.
