Oklahoma Self-Defense Act; modifying elements of eligibility for medical marijuana license holders. Effective date.

SB 39 modifies Oklahoma law to clarify that medical marijuana license holders may carry firearms while under the influence of medical marijuana, but only if the effects do not impair mental, emotional, or physical processes to the point of causing abnormal behavior. The bill also adds a new disqualifier for handgun license eligibility: a conviction for illegal drug use or possession, which must be considered under existing rules. These changes update the Oklahoma Self-Defense Act and related statutes to distinguish between medical marijuana use and illegal drug offenses in firearm possession rules.
