TSA Updates Policy to Allow Medical Cannabis on Flights

The Transportation Security Administration quietly updated its website April 27 to permit travelers to fly with medical cannabis, marking a significant shift in federal policy following marijuana's recent reclassification under the Controlled Substances Act.

The policy change comes less than two months after the Drug Enforcement Administration formally moved cannabis from Schedule I to Schedule III, ending its classification alongside heroin and LSD. The TSA's website now reflects guidance that acknowledges medical cannabis as a federally recognized therapeutic substance.

"TSA's screening procedures are focused on security and are designed to detect potential threats to aviation and passengers," the agency states in its updated guidance. The revision represents the first major federal travel policy shift since rescheduling took effect in March.

What the Policy Covers

The updated guidance applies specifically to medical cannabis products carried by patients with valid documentation from states with legal medical marijuana programs. TSA officers will no longer flag medical cannabis during routine security screenings, though travelers must still comply with individual state laws at their departure and arrival locations.

The policy creates a complex patchwork for travelers. While TSA won't confiscate medical cannabis at checkpoints, passengers could still face legal issues if they land in states without medical marijuana programs or attempt to cross international borders. Twelve states currently have no legal cannabis provisions whatsoever.

Dr. Rachel Gillette, a cannabis attorney based in Colorado, noted the practical challenges. "You might clear TSA in Denver with your medical card, but landing in Texas or Idaho with cannabis products could still result in state-level prosecution," she said. "Federal rescheduling doesn't override state law."

Industry Response

Cannabis industry advocates are calling the TSA policy update a watershed moment for patient access. The National Organization for the Reform of Marijuana Laws estimates that over 400,000 medical cannabis patients travel domestically each month, many of whom previously risked federal prosecution for bringing their medication on flights.

"This removes a major barrier for patients who need their medicine while traveling," said Morgan Fox, political director for the National Cannabis Industry Association. "But we need clear federal guidelines about quantity limits and acceptable product forms."

The TSA guidance doesn't specify quantity restrictions or address whether all cannabis product types—flower, concentrates, edibles, topicals—receive equal treatment under the new policy. The agency states only that medical cannabis is subject to the same liquid restrictions as other medications in carry-on luggage.

The Rescheduling Effect

The policy shift demonstrates how Schedule III reclassification is rippling through federal agencies beyond just the DEA. Since March, the Department of Veterans Affairs has also revised its guidance to allow VA doctors to discuss—though not prescribe—medical cannabis with veteran patients.

Research from the Congressional Research Service indicates that at least 47 federal policies related to controlled substances may require revision following marijuana's rescheduling. The TSA update represents one of the first concrete changes, though agencies including the Department of Transportation and Federal Aviation Administration have yet to issue updated guidance for their respective jurisdictions.

Cannabis remains illegal under international aviation treaties, meaning travelers on international flights—even to countries with legal cannabis—cannot bring products across borders. The TSA website explicitly states that its updated policy applies only to domestic travel within the United States.

What's Next

Industry observers expect additional federal agencies to clarify their cannabis policies throughout 2025. The Department of Homeland Security, which oversees TSA, has indicated it's reviewing other cannabis-related policies for potential updates.

For now, medical cannabis patients planning to fly should carry documentation proving their enrollment in a state medical marijuana program, including current certification from a licensed physician. Legal experts recommend researching destination state laws before traveling and avoiding international flights with cannabis products entirely.

The TSA did not respond to requests for comment about specific implementation details or officer training on the new policy.
