FAA Weighs New Marijuana Rules for Pilots and Air Traffic Controllers

Policy Review Scope and Timing

The FAA's review covers both pre-employment screening protocols and ongoing random testing requirements for certificate holders. The agency hasn't published a notice of proposed rulemaking. No timeline exists for policy changes. Under current regulations codified at 14 CFR §120.109, any individual performing safety-sensitive aviation functions is prohibited from using marijuana regardless of state law.

Thirty-eight states have legalized medical cannabis. Twenty-four have authorized adult-use programs. The gap between federal aviation law and state-level policy continues to widen.

Current Federal Aviation Marijuana Prohibitions

FAA Order 8000.95A establishes a permanent disqualification for airman medical certificates if an applicant tests positive for THC metabolites above 50 ng/mL. The threshold mirrors Department of Transportation cutoff levels but applies more strictly in aviation contexts. Pilots who hold a first-class, second-class, or third-class medical certificate face revocation proceedings upon a confirmed positive test.

Air traffic controllers employed by the FAA or contract tower operators fall under the same prohibition. Even a single instance of marijuana use within the prior two years can serve as grounds for medical certificate denial under 14 CFR §67.307.

Safety-Sensitive Function Definition

Safety-sensitive functions include flight crew duties, aircraft dispatch, maintenance actions, and ground security coordination. This broad scope covers approximately 580,000 active pilot certificate holders and 14,500 air traffic controllers as of 2026 FAA workforce data. Contract maintenance personnel and ramp workers at Part 121 carriers also fall within the testing pool.

The regulatory framework doesn't distinguish between THC from marijuana and hemp-derived cannabinoids, a gap that's generated enforcement complications as CBD product use has increased.

State Law Conflict and Enforcement Gaps

State medical marijuana programs don't create an exception to FAA drug testing requirements, even when a pilot holds a valid state registry card. Federal preemption under 49 USC §41713 ensures that aviation safety regulations override conflicting state statutes. Pilots who use cannabis under state medical programs risk certificate action identical to recreational users.

States including New York, New Jersey, and Connecticut have enacted employment protections for off-duty cannabis use, intensifying the conflict. Those protections don't extend to positions regulated under federal safety mandates.

DOT Drug Testing Program Precedents

The Department of Transportation's drug testing program, codified at 49 CFR Part 40, serves as the template for FAA protocols. DOT has maintained a zero-tolerance marijuana policy across all modes: trucking, rail, transit, pipeline, and maritime. State-level legalization hasn't changed that. Any FAA policy shift would require coordination with the DOT Office of Drug and Alcohol Policy and Compliance.

In December 2023, DOT issued guidance reaffirming that state laws don't alter federal testing requirements for safety-sensitive transportation workers. The FAA has cited that guidance in certificate denial cases.

Potential Policy Frameworks Under Consideration

The FAA could adopt impairment-based testing protocols, adjust THC detection thresholds, or create carve-outs for non-psychoactive cannabinoids. Each option carries distinct operational and legal risks. Impairment testing would require validated performance metrics that don't currently exist for THC. Raising the cutoff threshold from 50 ng/mL would align with some state programs but could trigger objections from safety advocacy groups.

A narrow exemption for CBD or other hemp cannabinoids would require amending the definition of marijuana in 14 CFR §120.7, which currently references the Controlled Substances Act's Schedule I classification.

Industry and Workforce Implications

Any relaxation of marijuana prohibitions could affect pilot hiring pipelines and medical certificate issuance rates. Regional carriers have reported difficulty filling cockpit positions, and some industry groups have suggested that cannabis policies contribute to the shortfall. The Air Line Pilots Association hasn't taken a formal position on policy changes.

The FAA's next step will likely be a request for public comment or an advance notice of proposed rulemaking. Until formal regulatory text is published, all current prohibitions remain in force.
