Carrying Under the Influence in Oklahoma

Oklahoma prohibits the carry of a handgun while the carrier is under the influence of alcohol or any controlled dangerous substance. The rule applies to both Oklahoma Self-Defense Act licensees and constitutional carriers. The principal statutes are Section 1289.9 and Section 1290.17 of Title 21 of the Oklahoma Statutes, with the related under-the-influence-discharge prohibition in Section 1272.2.

Section 1289.9 - Under-the-Influence Carry Prohibition

Section 1289.9 makes it unlawful for any person to carry a firearm while the person is under the influence of any intoxicating liquor, any drug, or any controlled dangerous substance, regardless of whether the person holds an SDA license. The prohibition applies in any place where the person would otherwise be authorized to carry, including:

• Public streets, sidewalks, parking lots, and other public areas
• Restaurants and other commercial premises
• Vehicles (Section 1289.7 carry coverage does not override Section 1289.9)
• Private property open to the public

Section 1290.17 - Licensee-Specific Prohibition

Section 1290.17 establishes a parallel under-the-influence prohibition specifically for SDA licensees, with additional administrative consequences:

• A licensee found carrying while under the influence is subject to misdemeanor prosecution.
• The OSBI may suspend the license for a defined period under Section 1290.16.
• A second or aggravating violation may result in revocation of the SDA license.

What "Under the Influence" Means

Oklahoma case law and the related driving-under-the-influence framework establish that "under the influence" includes:

• A blood alcohol concentration (BAC) at or above the 0.08 percent legal driving threshold, or
• Any lesser concentration of alcohol that has impaired the person's normal mental or physical faculties, or
• The presence of any controlled dangerous substance (including marijuana metabolite, regardless of impairment) in the person's blood, breath, urine, or saliva.

The relevant threshold for carry under Section 1289.9 is a person who is "under the influence" - the statute does not adopt a strict BAC number. Oklahoma courts have treated the standard as the same observable-impairment standard used in DUI prosecution, with the BAC threshold serving as a per se trigger.

Marijuana - Including Medical Marijuana

Oklahoma legalized medical marijuana by State Question 788 in 2018. Possession of a valid Oklahoma Medical Marijuana Authority patient license does not authorize the patient to carry a firearm while using marijuana. The interaction is governed by both state and federal law:

• State law: Section 1289.9 prohibits carry "under the influence" of any controlled substance. Marijuana is a controlled substance under Oklahoma law for this purpose, and a person who is actively impaired by marijuana use cannot lawfully carry.
• Federal law: 18 U.S.C. Section 922(g)(3) prohibits firearm possession by any person who is "an unlawful user of, or addicted to, any controlled substance." The federal government continues to classify marijuana as a Schedule I controlled substance under the Controlled Substances Act, even where state law authorizes its medical use. This means that medical marijuana cardholders are categorically barred from firearm possession under federal law - a distinct issue from the state-level under-the-influence carry rule.

A medical marijuana patient who is also an SDA licensee or a constitutional carrier faces a significant federal-law issue beyond the Section 1289.9 in-state impairment rule.

Section 1272.2 - Discharging a Firearm While Intoxicated

Section 1272.2 is a more serious sibling statute: it makes it a misdemeanor (with potential felony enhancement) to discharge a firearm while under the influence of alcohol or a controlled substance. This prohibition is separate from the carry-under-the-influence rule and applies whether the discharge is in self-defense (subject to the justification analysis under Section 1289.25 and Section 1289.26) or in some other context.

A defensive shooting by an impaired carrier is doubly problematic - the discharge itself may violate Section 1272.2, and the impairment may undercut the reasonableness analysis required for self-defense justification.

Penalty Schedule

• Section 1289.9 carry-under-the-influence: misdemeanor, with potential SDA license suspension or revocation
• Section 1272.2 discharge-under-the-influence: misdemeanor for first offense, with felony enhancement for second or subsequent offenses
• Federal 18 U.S.C. Section 922(g)(3) unlawful drug user possession: federal felony, up to 10 years and forfeiture

Practical Guidance

• Do not carry while drinking. The bright-line practical rule is to avoid carrying a handgun if alcohol or a controlled substance is in the carrier's system.
• A single drink does not necessarily impair, but a carrier in any doubt should secure the firearm (vehicle locker, hotel safe, locked container at home) before consuming alcohol.
• Bars and taverns where the primary business is on-premises alcohol consumption are off-limits under Section 1277 even for sober carriers. Restaurants that primarily serve food are permitted for an SDA licensee or constitutional carrier (subject to Section 1289.9 if the carrier is drinking).
• Medical marijuana patients should consult an attorney about the federal-law interaction with firearm possession.
• Self-defense by an impaired carrier is fact-dependent and risky; the reasonable-fear analysis in Section 1289.25 still applies, but impairment can affect the analysis and the credibility of the defense.
