The Transportation Security Administration updated its marijuana screening guidelines on May 23, 2026, clarifying that TSA officers don't actively search for cannabis but must refer any discovered marijuana to federal law enforcement because possession remains illegal under federal law.

TSA Revises Checkpoint Language on Cannabis Screening

TSA revised its public guidance on marijuana screening procedures, replacing previous ambiguous language with explicit statements about officer responsibilities under federal law. The update to the agency's "What Can I Bring?" webpage now states that while TSA security officers don't search for marijuana or other illegal drugs as a primary objective, they're required by federal statute to report any cannabis discovered during routine screening to law enforcement. The change comes as 38 states have legalized medical or adult-use marijuana programs. Travelers remain confused about what they can carry through airport checkpoints.

The revised guidance specifies that marijuana and certain cannabis-infused products remain illegal under the Controlled Substances Act, 21 U.S.C. § 812, which classifies cannabis as a Schedule I substance. TSA officers operate under federal jurisdiction at all U.S. airports, regardless of state-level legalization status.

Federal Jurisdiction Overrides State Legalization at Airports

State marijuana laws don't apply within federally regulated airport security checkpoints. A traveler departing from California or Colorado with state-legal cannabis faces the same federal enforcement risk as a traveler in Texas or Florida. When cannabis is detected during screening, TSA officers must defer to federal law—even if the passenger holds a valid state medical marijuana card or purchased the product from a licensed dispensary.

The agency's guidance doesn't specify whether officers will confiscate small amounts or refer all cases to local airport police. Enforcement discretion varies by airport and local law enforcement policies. Some jurisdictions instruct officers to dispose of small quantities without filing charges, while others process possession cases through federal magistrate courts.

Medical Marijuana Cards Provide No Federal Protection

TSA's updated language makes clear that state-issued medical marijuana authorization doesn't exempt patients from federal enforcement at checkpoints. Possession of a medical cannabis card or physician recommendation doesn't alter the federal prohibition. Patients traveling with cannabis derivatives such as oils, edibles, or vaporizer cartridges face the same referral protocols as recreational users.

The only exception carved out in the guidelines applies to FDA-approved cannabinoid medications such as Epidiolex, a CBD-based seizure drug, and synthetic THC products like Marinol and Syndros. These prescription medications are legal to carry in carry-on or checked baggage with proper documentation.

Hemp-Derived CBD Products Remain in Legal Gray Zone

TSA's revised guidance doesn't address hemp-derived CBD products containing less than 0.3% THC. Travelers face uncertainty. The 2018 Farm Bill removed hemp from the Controlled Substances Act, but TSA's website doesn't explicitly permit CBD oils, gummies, or topicals in carry-on bags. Officers screening bags can't visually distinguish hemp CBD from marijuana-derived THC products, and field testing equipment at most checkpoints doesn't differentiate cannabinoid sources.

Travelers carrying hemp CBD products risk bag searches and delays even if the products comply with federal hemp regulations. TSA recommends passengers carry certificates of analysis or product labels showing THC content, but the guidance stops short of guaranteeing clearance.

Enforcement Data and Traveler Confusion Persist

TSA doesn't publish data on marijuana referrals or confiscations, but airport police reports show inconsistent enforcement nationwide. Airports in states with legal markets report fewer criminal charges filed after TSA referrals. Airports in prohibition states more frequently process possession cases. This lack of uniform policy creates confusion for travelers attempting to comply with both state and federal rules.

The next inflection point will come if the DEA finalizes its proposed rescheduling of cannabis from Schedule I to Schedule III, which wouldn't change TSA enforcement protocols but could influence prosecutorial discretion at federal facilities.
