The Transportation Security Administration (TSA) has updated its guidance for medical marijuana, listing it as allowed in both carry-on and checked bags, subject to “special instructions.”

The update, listed on TSA’s “What Can I Bring?” page, states that medical marijuana is marked “Yes” for both carry-on bags and checked bags.

On the page, the agency notes that  “TSA’s screening procedures are focused on security and are designed to detect potential threats to aviation and passengers. Accordingly, TSA security officers do not search for illegal drugs, but if any illegal substance or evidence of criminal activity is discovered during security screening, TSA will refer the matter to a law enforcement officer.”

The guidance does not mean travelers are broadly protected from legal consequences for carrying marijuana through an airport. Instead, it reflects TSA’s long-standing position that its officers are primarily looking for weapons, explosives and other threats to air travel, while clarifying that medical cannabis is an allowable item.

The agency also notes that the final decision on whether an item is allowed through a checkpoint rests with the TSA officer conducting the screening.

The update comes as the federal government is in the process of rescheduling cannabis. The DOJ recently issued a final order moving FDA-approved and state-legal cannabis to Schedule III, with an administrative hearing scheduled for June 29 to begin the process of moving all cannabis to Schedule III.
